Overview

What Is A Dietary/Food Supplement?

A food supplement, or  a dietary supplement, is designed to provide nutrients or compounds that a person might not be sufficiently consuming. These supplements can include vitamins, minerals, amino acids, antioxidants, enzymes, and herbs. They are available as tablets, capsules, powders, and liquids. While they can support a balanced diet, they are not intended to replace whole foods or be a sole source of nutrition. Instead, they ensure that an individual’s nutrient intake meets their body’s demands for proper functioning, especially when their diet lacks specific nutrients.

Are Food Supplements Healthy?

Food supplements can be healthy when used appropriately and with a clear understanding of their purpose. They are beneficial in filling nutritional gaps and supporting specific health needs when dietary intake is insufficient. However, they are not a cure-all and should not be a substitute for a balanced and varied diet. Excessive or inappropriate use of supplements can lead to health issues, including nutrient imbalances and unwanted interactions with medications. Therefore, it is vital to use supplements judiciously, under the guidance of a healthcare professional, and as part of an overall healthy lifestyle.

Why We Need Food Supplements?

We may need food supplements to address specific nutritional deficiencies or to meet increased nutrient demands that isn’t fulfilled just through diet. Factors such as aging, health conditions, dietary restrictions, or special life stages (like pregnancy or intense physical training) can increase the need for certain nutrients. In such cases, supplements are the practical means to ensure adequate nutrient intake. However, it is essential to acknowledge that supplements are an adjunct to, not a substitute for, a well-rounded diet, and their use should be based on individual nutritional requirements and under professional guidance.

What Food Supplements Should You Take?

The need for food supplements varies largely among individuals, depending on diet, lifestyle, age, health status, and specific nutritional needs. It is best to consult with a healthcare professional or a registered dietitian to assess your dietary intake and determine if you have any nutritional gaps that require supplementation. Generally, they may recommend appropriate supplements if your diet lacks certain nutrients, such as Vitamin D during the winter months, or calcium for bone health. However, indiscriminate use of supplements can lead to unnecessary intake and potential nutrient imbalances, so personalized advice is crucial.

Are Fortified Foods Better Than Supplements?

Fortified foods can offer a more food-based approach to increasing the intake of specific nutrients and are beneficial in improving the overall nutrient profile of the diet without the need to take pills or capsules. They can be helpful in reaching populations with specific nutrient deficiencies and are often part of public health strategies to address those deficiencies. However, the advantage of fortified foods over supplements depends on individual dietary patterns, nutritional needs, and preferences. While fortified foods can seamlessly integrate nutrients into the diet, supplements can provide higher, more targeted doses of specific nutrients when needed. Both approaches have their place in a comprehensive strategy to meet nutritional needs.

Why Can't Supplements Replace Food?

Supplements cannot replace food because whole foods provide a complex nutritional matrix that supplements cannot replicate. Along with vitamins and minerals, food also contains fiber, antioxidants, and numerous other bioactive compounds that work together to promote health. The interaction of these compounds within the body’s biological systems contributes to proper digestion, absorption, and the holistic functioning of the human body. Moreover, the experience of eating—tasting, digesting, and metabolizing whole foods—plays a crucial role in satiety, appetite regulation, and the enjoyment of meals, aspects that supplements alone cannot fulfill.

Impact Of Dietary/Food Supplements

Proper use, tailored to individual health needs and based on scientific evidence, can support disease prevention, immune function, and overall physical and mental performance. However, the balance is key, as indiscriminate use without professional guidance might lead to unintended consequences. As such, dietary supplements represent a valuable tool in the modern health landscape, promising benefits when integrated thoughtfully into a holistic approach to health and wellness.

What Foods And Supplements Lower Cholesterol?

Foods rich in soluble fiber, such as oats, barley, beans, lentils, fruits, and vegetables, can help lower cholesterol levels. Omega-3 fatty acids, found in fish like salmon and mackerel,  flaxseeds and walnuts, have been shown to lower triglycerides and improve heart health. Supplements such as red yeast rice, psyllium husk, and plant sterols can also help reduce cholesterol levels. However, it’s crucial to use these supplements under medical supervision, as they can interact with medications and might not be suitable for everyone.

Which Food Supplement Is Best For Bodybuilding?

Protein supplements are popular for bodybuilding as they support muscle repair and growth. Whey protein is a favorite due to its high biological value and fast absorption. Creatine is another widely used supplement known for improving strength, increasing lean muscle mass, and helping muscles recover quickly during exercise. Other supplements like branched-chain amino acids (BCAAs), beta-alanine, and L-glutamine can also support muscle recovery and growth. However, it’s essential to approach supplementation with a strategy that complements a well-planned diet and workout routine, and ideally, under the guidance of a fitness or health professional.

Vitamin A Levels refer to the concentration of vitamin A in the body, a fat-soluble vitamin  essential for vision, the immune system, and reproduction. Vitamin A also helps the heart, lungs, kidneys, and other organs work properly.

Vitamin A levels have significant genetic roots. For example, genetic variations in the TRR gene have been linked to vitamin A levels in the body. The TTR gene is responsible for coding the transthyretin protein. Transthyretin plays a crucial role in distributing vitamin A and the hormone thyroxine across the body. 

Read about this and other interesting genetic markers here.

Vitamin B5 Levels, also known as pantothenic acid levels, refer to the concentration of this vitamin in the body. Vitamin B5 is essential for energy production, the synthesis of fatty acids, and the metabolism of fats, proteins, and coenzyme A. Read in detail about the genetics of vitamin B5 levels here. 

Vitamin B6 Levels indicate the concentration of vitamin B6, or pyridoxine, in the body. It is involved in the metabolization processes of protein, fats, and carbohydrates. It further aids in new red blood cells formation and supports the function of the nervous and immune systems.

Vitamin B6 levels have been shown to vary based on variations in genes like ALPL and NBPF3.

Vitamin B12 Levels measure the amount of vitamin B12, a crucial nutrient for nerve tissue health, brain function, and the production of red blood cells. Deficiency can lead to anemia and neurological issues.

Vitamin B9 (Folate) Levels indicate the concentration of folate or folic acid, a B vitamin necessary for proper brain function, plays a crucial role in mental and emotional health. It is also essential for producing DNA and RNA and particularly important in aiding rapid cell division and growth, such as during infancy and pregnancy.

Vitamin B9 levels in the body are strongly associated with genetic variations in the MTHFR gene. The MTHFR gene is a prominent gene that influences several critical functions related to growth and development. We will discuss the functions of this gene in more detail in a future article, stay tuned!

Vitamin D Levels refer to the concentration of vitamin D, a fat-soluble vitamin essential for strong bones because it helps the body use calcium from the diet. Traditionally, vitamin D deficiency has been linked to rickets, a disease in which the bone tissue does not properly mineralize, leading to soft bones and skeletal deformities.

The GC gene, which codes for the vitamin D Binding Protein, a pivotal player in vitamin D level regulation, is closely tied to how vitamin D influences our wellness.

Zinc Levels refer to the bodily concentration of zinc, a critical mineral for a healthy immune system, wound healing, DNA synthesis, and cell division. Zinc also supports regular growth and development during pregnancy, childhood, and adolescence. We require zinc also for proper sense of taste and smell.

Zinc levels have a genetic component. Studies have found variations in genes like PPCDC and CA1 to influence blood zinc levels.

Iron Levels denote the amount of iron in the body, an essential mineral critical for the production of hemoglobin, a protein in red blood cells that carries oxygen from the lungs to the rest of the body. Iron is also necessary for growth, development, normal cellular functioning, and for synthesizing some hormones and connective tissue.

Genetic variations in genes like HFE and TMPRSS6 influence iron levels.

Cholesterol Levels traits (two of them) refer to the amount of cholesterol in the blood, either the low-density lipoprotein (LDL, or “bad” cholesterol) or the high-density lipoprotein (HDL, or “good” cholesterol). While cholesterol is essential for forming cell membranes, certain hormones, and vitamin D, high LDL cholesterol levels increase the risk of heart disease and stroke. 

Genetic factors play a significant role in determining an individual’s HDL cholesterol levels. Read about it here.

Copper Levels indicate the concentration of copper in the body, a trace mineral vital for making red blood cells and maintaining nerve cells and the immune system. It also helps the body form collagen, absorb iron, and play a role in energy production.

The SNP rs1175550, located in the SMIM1 gene, is linked to serum copper concentrations. Individuals carrying the A allele of this SNP are more susceptible to lower levels of copper. 

DHA Levels refer to the amount of docosahexaenoic acid, a type of omega-3 fatty acid that is a major structural component of the human brain, cerebral cortex, skin, and retina. Adequate DHA levels are crucial for brain health, visual development, and reducing inflammation. 

From the genetic perspective, variations in the ELOVL2 gene, responsible for producing proteins that extend the chain length of omega-3 and omega-6 fatty acids, have been linked to reduced levels of DHA. This connection is significant, considering the crucial part DHA plays in maintaining brain health and supporting cognitive functions.

Liver Enzyme Levels refer to the concentrations of  the liver enzymes, including alanine-aminotransferase (ALT), aspartate transaminase (AST), alkaline phosphatase  (ALP), and gamma-glutamyl transferase (GGT). These enzymes are released into the bloodstream when the liver is damaged. Monitoring these levels helps diagnose and monitor liver damage or diseases. 

A 2008 GWAS across three populations (7,715 individuals) and validated in three additional cohorts (4,704 individuals) identified specific genetic loci associated with levels of liver enzymes, including ALT, GGT, and ALP. Significant loci were discovered for ALT (on chromosomes 10 and 22), one for GGT (on chromosome 12), and three for ALP (on chromosomes 1, 6, and 10). The study also confirmed known associations with GGT and ALP levels.

CoQ10 Levels refer to the amount of Coenzyme Q10 in the body, a substance that helps convert food into energy and acts as a powerful antioxidant, protecting cells from damage and playing a part in the metabolism.

Genetics significantly influences CoQ10 levels. A 2016 study investigated the genetic factors influencing serum CoQ10 levels. A meta-analysis of two Northern German cohorts identified two significant genetic loci linked to CoQ10 levels. The COLEC12 gene on chromosome 18 and the NRXN-1 gene on chromosome 2, previously associated with neuronal diseases, showed the strongest associations. 

Probiotic Need reflects the necessity for probiotics, live beneficial bacteria and yeasts that are good for the digestive system. They help keep the gut healthy and are often referred to as “good” or “friendly” bacteria because they help keep the gut environment healthy.

A 2016 study examined how genetics influences the gut microbiome by analyzing metagenomic sequencing data from 1,514 individuals. Researchers identified significant genetic associations with microbial species, pathways, and gene ontology categories, pinpointing nine loci linked to microbial taxonomies and 33 loci associated with microbial pathways and gene ontology terms. The study also highlighted 32 loci, related to complex diseases, immunity, and food preferences, with a suggestive association level. Notably, the findings include new associations, like those at the genome-wide significance for CLEC4F–CD207 and CLEC4A–FAM90A1. 

Magnesium Levels indicate the amount of magnesium in the body, an essential mineral for bone health and proper function of nerves, muscles, etc. Magnesium is also involved in over 300 biochemical reactions in the body.

Variations in the TRPM6 and ATP2B1 genes are commonly associated with changes in magnesium levels and an increased likelihood of developing hypomagnesemia.

 

Thyroid Function refers to how well the thyroid gland works, producing hormones that regulate metabolism, heart rate, body temperature, and more. Tests often measure levels of Thyroid Stimulating Hormone (TSH), T3, and T4 to assess thyroid function.

Genetics significantly influence thyroid hormone levels, TSH concentrations, and the likelihood of developing autoimmune thyroid diseases. Studies indicate that genetic factors account for nearly 67% of the variation in thyroid hormone and TSH levels. While research has identified specific genes, like those for phosphodiesterase 8B (PDE8B), iodothyronine deiodinase 1 (DIO1), F-actin-capping protein subunit beta (CAPZB), and the TSH receptor, as contributors to these variations, they explain only a little portion of the hormone level differences. More genes and genetic mechanisms affecting thyroid hormone levels remain undiscovered.

Melatonin Levels measure the concentration of melatonin, a hormone the pineal gland produces to regulate the sleep-wake cycle. It is often called the “sleep hormone” as high levels can help you fall asleep.

Genetics significantly influences melatonin levels. For example, the MTNR1B gene variant is linked to endogenous melatonin signaling, sleep status, and circadian rhythm.

Calcium Levels indicate the amount of calcium in the body, essential for maintaining strong bones and carrying out many vital functions such as muscle contraction, blood clotting, and nerve transmission.

Phosphorus Levels measure the amount of phosphorus, or phosphate, in the body, an essential mineral involved in hundreds of cellular activities everyday. The body uses phosphorus to repair cells and tissues, to make the energy needed for daily activities, and to filter waste out of the kidneys.

Glomerular Filtration Rate (GFR) is a test to check how well the kidneys work. It estimates how much blood passes through the glomeruli, tiny filters in the kidneys, each minute. Several genetic factors contribute to GFR regulation, influencing the efficiency of the glomerular filtration process. 

For example, genetic variants in SHROOM3, such as the SNP rs17319721, have been linked to an increased risk of Chronic Kidney Disease (CKD) and reduced GFR.

How Do Genes Influence Your Vitamin B5 Needs?

Aira on August 16, 2024

What is Vitamin B5?

Vitamin B5, also known as pantothenic acid, is an essential nutrient present in various foods and supplements. It supports the body in producing coenzyme A (CoA) and acyl carrier protein, crucial for tasks such as breaking down fats. During consumption, the majority of Vitamin B5 comes in diverse forms, but the body converts them into a straightforward form that is usable.

Vitamin B5 Levels

What Does Vitamin B5 Do to Your Body?

Vitamin B5 serves many essential functions in the body, contributing to overall wellness. Here are some key roles that vitamin B5 plays:

  • Making Coenzyme A 

Vitamin B5 plays a role in making coenzyme A, a key player in various metabolic pathways. Coenzyme A is instrumental in the synthesis of fatty acids, facilitating the conversion of dietary components into essential fats and cholesterol. 

Additionally, it contributes to the production of sphingosine, a lipid-like molecule that functions in transmitting chemical messages within the body’s cells. Notably, the liver relies on coenzyme A to metabolize certain drugs and toxins safely.

  • Supporting a Good Digestive System

Maintaining a good digestive system is crucial for overall well-being, directly impacting nutrient absorption and utilization. Vitamin B5 plays a significant role in this process, assisting in the use of other essential vitamins, especially vitamin B2.

The collaboration between these vitamins optimizes the efficiency of nutrient absorption, fostering optimal digestive function. Through its support for the digestive system, Vitamin B5 helps guarantee that the body can effectively extract and use nutrients, contributing to overall well-being and vitality.

  • Skin Moisturization and Wound Healing

The importance of skin moisturization and efficient wound healing cannot be overstated. Vitamin B5 has demonstrated its efficacy in both these aspects. Studies indicate that Vitamin B5 serves as a potent moisturizer for the skin, promoting hydration and skin wellness.

Furthermore, research has shown promising results in using Vitamin B5 as a dietary supplement for facial acne, with a significant reduction in total lesion count over a 12-week period. While these findings are encouraging, further clinical trials are warranted to validate the results.

  • Cholesterol and Triglyceride Regulation

Maintaining optimal cholesterol and triglyceride levels is crucial for cardiovascular wellness. Vitamin B5 has been implicated in potentially contributing to the regulation of cholesterol and blood triglyceride levels, as suggested by some studies. 

However, it is imperative to highlight that any approach to managing cholesterol levels should only be undertaken under medical supervision. Vitamin B5’s potential role in this regard emphasizes the interconnectedness of nutrition and cardiovascular wellness, highlighting the need for a comprehensive and medically guided approach to address lipid profile imbalances.

The roles of vitamin B5 are crucial in maintaining overall well-being. Therefore, it is important to balance its levels in our bodies to keep us in top shape.

Genetics of Vitamin B5 Levels

Understanding the genetics of vitamin B5 levels holds the promise of personalized nutrition and targeted wellness interventions. By identifying specific genetic variations related to vitamin B5 metabolism, individuals can receive tailored dietary suggestions and interventions to optimize their nutrient levels.

The following are some genes that play a role in Vitamin B5 levels.

PANK 2

This gene encodes Pantothenate kinase 2, an enzyme that catalyzes the first step of vitamin B5 (pantothenic acid) metabolism, converting it to 4’-phosphopantothenic acid. This enzyme is inhibited by coenzyme A, a derivative of vitamin B5 that is essential for many biochemical reactions.

SLC5A6

The SLC5A6 gene provides instructions for making a protein called the sodium (Na+): multivitamin transporter (SMVT). This protein acts as a carrier that helps bring important vitamins, including vitamin B5, into our cells.

When there are changes in this gene, such as when the SNP rs1395 is present, it can influence the function of the SMVT protein. A study suggests that individuals carrying the A allele of rs1395 may experience variations in how their cells absorb and handle vitamin B5.

It is important to note that while information on genetic factors affecting vitamin B5 levels provides valuable insights, it is just one aspect of a holistic approach to wellness. Lifestyle factors, environmental influences, and overall wellness assessments should also be considered to comprehensively understand an individual’s well-being.

Non-Genetic Factors Influencing Vitamin B5 Levels

As we investigate the role of vitamin B5 in our bodies, it’s essential to recognize that genetic factors aren’t the sole influencers. External elements, such as diet, medications, stress, and age, play pivotal roles in shaping the intricate dynamics of vitamin B5 metabolism.

Diet

A diet that is low in vitamin B5 or high in processed foods that contain little or no vitamin B5 may lead to deficiency. Conversely, a diet that is rich in vitamin B5 or fortified with vitamin B5 may increase the levels of this vitamin in the body.

Medications

Some medications may interfere with the absorption or metabolism of vitamin B5, including antibiotics, oral contraceptives, anticonvulsants, and cholesterol-lowering drugs. These medications may reduce the levels of vitamin B5 in the body or increase the requirement for this vitamin.

Stress

Stress may increase the demand for vitamin B5, as it is involved in the production of stress hormones, such as cortisol and adrenaline. Stress may also affect the intestinal microbiota, which may alter the production of vitamin B5 by the bacteria.

Age

Age may affect the levels of vitamin B5 in the body, as older adults may have lower absorption and higher excretion of vitamin B5 compared to younger adults. Older adults may also have a lower intake of vitamin B5 from the diet or lower production of vitamin B5 by intestinal bacteria.

Keeping our vitamin B5 levels in balance is easier when we pay attention to how we treat our bodies. Being aware of our habits and surroundings helps us make choices that support good vitamin B5 levels, which is important for our overall well-being.

How to tell if you’re deficient in vitamins?

Aira on August 16, 2024

In a fast-paced world, everything changes, including food. Whereas before, food was a source of strength and energy for people to go about their daily tasks, nowadays, food is also a luxury and sometimes even an experience.
The way that food is prepared has changed so much within the recent decades, and with that, its nutritional value. 

For many, a nice, hearty, and delicious meal cooked at home has been replaced with everyday cheap, accessible, and delicious fast food.

What is Nutritional Deficiency?

As a result of this, health concerns have also been on the rise. Food is, after all, everyone’s first source of vitamins and minerals. One of the major health concerns that have been growing recently is nutrient deficiency. Fast food and other types of commercial food have been directly linked to the rise in nutrition deficiencies for many. 

By definition, nutritional deficiency is when an individual’s body does not get or is unable to absorb the proper amount of nutrients such as vitamins and minerals. People who have nutritional deficiencies may need supplements for their bodies to function properly. Nutritional deficiency in itself is not a disease but it can be the cause of other complications down the road such as anemia, which has many types depending on what caused the condition. 

Is Nutritional Deficiency Influenced by DNA?

While genetics is known to pass down food intolerances and allergies, recent research has shown that genetics also play a role in nutritional deficiencies. Thanks to technological advances, these factors can now be traced via DNA sampling and analyses. LifeDNA is one of the most premium personalized wellness companies that offer genetic testing and analysis for nutritional needs and a complete and comprehensive report for individuals who want to know more about their potential food response and sensitivities and whether or not they have deficiencies.

Want to discover your body’s genetic likelihood for certain vitamin and mineral deficiences? Get LifeDNA’s personalized wellness and nutrition analysis today.

How to tell if you're deficient in vitamins

Nutritional deficiency can manifest in many different ways depending on which particular vitamin or mineral the body is not getting enough of. There are many telltale signs of deficiency but they sometimes blur altogether that it is difficult to pinpoint what particular nutrient your body needs. Blood tests are the most efficient but your primary care physician might recommend other tests just to rule out other causes for your symptoms. 

There are some common symptoms that you might want to watch out for if they continue to persist. Some of them may or may not include severe hair loss, extreme and chronic fatigue, irregular heartbeat (tachycardia), muscle weakness, slow healing of wounds, frequent infections, etc. These symptoms may be due to other underlying health conditions so talking to your physician is always your best bet.

What Vitamin Deficiencies Cause Tingling in the Hands and Feet?

Vitamin B12 deficiency can cause a “pins and needles” sensation in both the hands and feet. They may vary in intensity and can come and go. This is because B-12 plays a crucial role in the nervous system, the lack or absence of it can increase the risk of developing nerve conduction problems and even nerve damage if not treated properly and immediately. Can low B12 cause dizziness? The answer is yes and this can turn chronic (vertigo) if not addressed with supplements. 

Do you have a higher likelihood of Vitamin B-12 deficiency based on DNA? Find out now with Free Vitamins Report – available when you get your Nutrition Report today. 

What Vitamin Deficiency Causes Muscle Cramps?

Muscle cramps and pain are most common for people with Vitamin D deficiency. The body cannot produce Vitamin D on its own; the main source is the sun. The whole process is complex but, when the sunlight hits the skin, the body can convert it into Vitamin D. During the winter or seasons when the sun is scarce, people are at a higher risk of developing Vitamin D deficiency. 

Supplements come in handy and food rich in Vitamin D such as salmon, cod, tuna, beef liver, and dairy products fortified with Vitamin D. Can low Vitamin D cause shortness of breath? Studies show that being low on the vitamin has to cause a myriad of respiratory problems including shortness of breath.

How Do Genes Influence Your Vitamin D Needs?

Aira on August 12, 2024

What is Vitamin D?

Vitamin D, also referred to as the “sunshine vitamin,” is a special micronutrient that our bodies need, and we also make it ourselves. It’s a kind of vitamin that dissolves in fat, and one of its main jobs is helping our bodies take in and keep important minerals such as calcium and phosphorus, which are highly important for making strong bones.

But vitamin D does more than just help our bones. Studies show that it can slow down the growth of cancer cells, help our bodies fight off infections, and reduce swelling. Our organs and tissues have special components that can grab onto vitamin D, suggesting that this vitamin has more functions than just reinforcing bones.

Vitamin-D

Why Does Our Body Need Vitamin D?

Vitamin D is essential for various crucial functions in the body.

Optimizing Bone Wellness

One of the primary roles of vitamin D is to support the absorption of calcium in the intestines, ensuring the body maintains proper levels of calcium and phosphorus in the blood. This balance is critical for good mineralization of bones. In children, lack of vitamin D can lead to rickets, causing the bones to soften and resulting in a bowlegged appearance. Similarly, adults with vitamin D deficiency may experience osteomalacia, characterized by weakened bones and reduced bone density, leading to muscular weakness. Prolonged vitamin D deficiency can also contribute to the development of osteoporosis.

Supporting Immunity

Vitamin D plays a crucial role in supporting immune function, and maintaining an adequate intake may help reduce the risk of autoimmune conditions. Some research suggests a potential link between long-term vitamin D deficiency and the onset of autoimmune conditions such as diabetes, asthma, and rheumatoid arthritis.

While studies in test tubes have demonstrated a positive impact of vitamin D on the immune response of human cells, further research in controlled human trials is needed to confirm these findings.

Understanding the diverse roles of vitamin D in maintaining bone wellness and supporting the immune system underscores its significance in overall well-being. Continued exploration through research will contribute to a comprehensive understanding of the far-reaching effects of vitamin D on the human body.

Genetics of Vitamin D Levels

Genetics plays a part in determining our vitamin D levels, influencing how our bodies handle and regulate this important nutrient. Scientists are exploring the impact of our genes on vitamin D to better understand its role in supporting our well-being.

GC Gene

Vitamin D’s influence on wellness is closely tied to the GC gene, which codes for the Vitamin D Binding Protein, a pivotal player in the regulation of vitamin D levels. Research indicates that variants in this gene can significantly influence the concentration of vitamin D in the bloodstream.

NADSYN1/DHCR7 Gene

In the context of vitamin D dynamics, the NADSYN1/DHCR7 gene emerges as a factor of interest. Genetic analyses concerning variants such as rs12785878 provide insights into the regulatory mechanisms influencing circulating 25-hydroxyvitamin D levels.

CYP2R1 Gene

Within the complex landscape of vitamin D metabolism, the CYP2R1 plays a discernible role. This enzyme is a microsomal vitamin D hydroxylase that converts vitamin D into the active ligand for the vitamin D receptor. Examining diverse groups of people reveals associations between specific gene variants, notably rs10741657, and the modulation of circulating 25-hydroxyvitamin D concentrations, contributing valuable genetic insights to the understanding of vitamin D regulation.

CYP24A1 Gene

In the intricate framework of vitamin D homeostasis, the CYP24A1 stands out as a contributor. This mitochondrial protein initiates the degradation of 1,25-dihydroxyvitamin D3, the physiologically active form of vitamin D3, by hydroxylation of the side chain. In regulating the level of vitamin D3, this enzyme plays a role in calcium homeostasis and the vitamin D endocrine system. 

Through systematic analysis and replication efforts, associations between certain gene variants, such as rs17216707, and the regulation of vitamin D levels become apparent, enriching our understanding of the genetic determinants of vitamin D balance.

Two other genes associated with Vitamin D levels and found on the LifeDNA’s Vitamin D Levels Report are AMDHD1 (rs10745742) and SEC23A (rs8018720), but their functional role in regulating Vitamin D levels is less known at this time. 

Unraveling the genetic factors affecting vitamin D levels provides a deeper understanding of how our bodies manage this essential nutrient. As ongoing research sheds light on the intricate interplay between genetics and vitamin D regulation, these insights can inform personalized approaches to wellness, fostering a clearer path toward optimal well-being.

Non-Genetic Factors Influencing Vitamin D Levels

Sun Exposure

The amount of sunlight available varies with geographical location, influencing the natural vitamin D synthesis by our bodies. People living at higher latitudes may experience reduced sun exposure, particularly during certain seasons or times of the day, impacting their ability to produce sufficient vitamin D.

Atmospheric Components

The atmospheric conditions, including cloud cover and pollution, can hinder the penetration of UVB rays necessary for vitamin D production. Such variations in weather patterns contribute to the risk of impaired vitamin D status, especially in regions with inconsistent sunlight.

Clothing and Sunscreen Use

Clothing coverage and the application of sunscreen act as physical barriers that limit the skin’s exposure to sunlight. While these practices are essential for sun protection, they can reduce the synthesis of vitamin D, contributing to the prevalence of low vitamin D levels.

Skin Pigmentation

Individuals with darker skin pigmentation have a natural sunscreen effect, requiring more extended sun exposure to produce the same amount of vitamin D as those with lighter skin. 

Age and Obesity

Age and obesity play roles in vitamin D metabolism. Aging may reduce the skin’s ability to synthesize vitamin D. At the same time, obesity can sequester vitamin D in fat tissues, affecting its bioavailability and contributing to the risk of vitamin D deficiency.

Chronic Illnesses

Several chronic illnesses, such as certain autoimmune conditions and metabolic disorders, are associated with an increased risk of vitamin D deficiency.

In summarizing these factors, it becomes evident that vitamin D levels are profoundly influenced not only by genetics but also by various non-genetic elements, emphasizing the need for a comprehensive approach to address and mitigate the widespread prevalence of low vitamin D levels across the globe.

How to Optimize Vitamin D Levels Naturally?

Understanding the sources and metabolism of vitamin D is crucial for optimizing its levels naturally. The primary source of vitamin D is cutaneous synthesis, where sunlight triggers the conversion of provitamin D to previtamin D3. However, food sources contribute only in moderate amounts, making supplementation necessary for those with limited sun exposure or reduced cutaneous synthesis, such as older adults.

Get Sun Exposure

Sunlight exposure, specifically UVB radiation, is pivotal for synthesizing vitamin D in the skin. Even a short duration of sunlight on specific body parts can produce significant amounts of vitamin D. Factors such as age, skin color, season, weather, latitude, and sunscreen use influence this synthesis. While sunlight is essential, caution is needed to avoid skin damage, while factors such as sunscreen and increased skin pigmentation can reduce vitamin D synthesis.

Eat Food Rich in Vitamin D

Food sources contribute to dietary vitamin D, with fatty fish, eggs, and fortified foods being notable examples. However, these are often not consumed in quantities sufficient for optimal vitamin D levels. For example, mushrooms, when exposed to UV light, provide a plant-based vitamin D source. While some foods are fortified, their consumption varies, making it challenging to rely solely on dietary intake for adequate vitamin D.

Consider Supplementation

Supplements become crucial, especially for individuals with limited sun exposure or reduced cutaneous synthesis, such as older adults. Fortified foods such as milk, butter, and cereals, along with vitamin D supplements, offer a reliable way to ensure consistent and adequate vitamin D intake. This is particularly important for those with malabsorption conditions, where dietary sources alone may not suffice.

Improving vitamin D levels requires a holistic approach, combining sun exposure, dietary adjustments, and supplementation. While sunlight remains a vital natural source, dietary shifts and fortification contribute to meeting vitamin D needs. Balancing nutrient intake with environmental considerations adds complexity to the equation, emphasizing the importance of personalized strategies for achieving optimal vitamin D levels.

Genetic Influence on Selenium Levels

Aira on August 12, 2024

What is Selenium?

Selenium is a trace mineral found in soil, water, and certain foods, and it is necessary for the proper functioning of the body in small amounts. It is a component of selenoproteins, which are important antioxidant enzymes that protect cells from oxidative damage and support thyroid health. It is important in supporting a healthy metabolism, immune system, and cognitive function, and may also help reduce the risk of certain cancers.

Good food sources of selenium include Brazil nuts, seafood, lean meats, eggs, and whole grains. The amount of selenium in foods depends on the selenium content of the soil where the food was grown.

Most people in the U.S. consume adequate amounts of selenium from their diet with the recommended daily intake of 55 mcg for adults. The safe upper limit is 400 mcg (micrograms) per day.

Selenium is available as a dietary supplement, commonly in the form of selenomethionine or selenium-enriched yeast. However, supplements are not necessary if one is getting enough from food sources, in order to avoid selenium toxicity which is rare but can occur with excessive supplementation, causing nausea, hair loss, and nervous system problems. 

Genetic Influence on Selenium Levels

Benefits of Selenium in the Body

Selenium supplementation has been found to significantly reduce insulin resistance and serum insulin levels in patients with cardiometabolic diseases. It has also been shown to increase high-density lipoprotein cholesterol (HDL-C) levels, which can have a beneficial impact on cardiovascular health.

For patients with kidney disease, selenium deficiency is common and can lead to complications like cardiovascular disease, bone loss, and anemia. Selenium supplementation may help address these issues, though more research is needed to fully understand its role.

Some studies have also suggested that selenium may have benefits in treating depression and sleep disorders. However, the evidence on this is more limited compared to the other areas discussed.

Furthermore, selenium has been shown to have therapeutic benefits against various cancers, including hematological malignancies. Supplementing chemotherapy and radiotherapy with selenium has been found to alleviate side effects and improve the quality of life in cancer patients. Selenium levels in patients have also been used as a diagnostic marker to track the efficiency of cancer treatments.

How Genetics May Influence Selenium Levels

Genetics plays a significant role in influencing selenium (Se) levels in individuals. Genome-wide association studies (GWAS) have identified various single-nucleotide polymorphisms (SNPs) associated with blood selenium concentrations.

In a GWAS conducted on adult cohorts from Australia and the UK, significant associations between certain SNPs and selenium levels were observed. A locus on chromosome 5 was found to be significant in both cohorts, suggesting genetic variations affecting the metabolism of sulfur-containing amino acids and selenium compounds. This genetic locus spans several genes, such as the ARSB, DMGDH, and BHMT, and contains at least 10 SNPs that can have an effect on blood selenium levels. 

Similarly, a GW meta-analysis of toenail selenium concentrations, reflecting prolonged exposure, identified a locus near DMGDH especially at the SNP rs248381, confirming the influence of genetic variation at this 5q14 locus on selenium levels. Furthermore, using genome-wide summary statistics from both toenail and blood selenium, statistical evidence of polygenic overlap was observed and meta-analysis of results from studies of either trait yielded a second significant locus at 21q22.3, harboring gene CBS and SNPs rs6586282, rs234709 and rs1789953. 

Genetic Factors in Response to Selenium Supplementation

GWAS have also elucidated the genetic basis of responses to selenium supplementation.

In a study involving participants of European descent, SNPs in the NEK6 and the above-mentioned DMGDH/BHMT regions were found to potentially influence changes in selenium concentrations after supplementation. Specifically, rs56856693, located upstream of NEK6, and SNPs in the DMGDH/BHMT region were nominally associated with changes in selenium concentrations following supplementation.

These findings underscore the intricate interplay between genetics and selenium metabolism. Genetic variations in genes related to sulfur-containing amino acid metabolism and homocysteine pathways influence selenium levels and responses to supplementation. Understanding these genetic factors can provide insights into individual differences in selenium status and may have implications for personalized nutrition and health interventions.

Non-Genetic Factors Influencing Selenium Levels

There are several key factors that can influence selenium levels aside from genetics:

  • Dietary intake: Selenium levels are influenced by dietary intake, as selenium is obtained primarily through the diet. Factors like the selenium content of the soil and food sources can impact an individual’s selenium status.
  • Health conditions: Certain health conditions, such as cancer and kidney disease, can lead to lower selenium levels. Cancer progression has been found to be inversely related to serum selenium levels. Patients with kidney disease are also prone to selenium deficiency due to increased loss during dialysis.
  • Lifestyle factors: Smoking and alcohol consumption have been found to negatively impact selenium levels in some studies. Nutritional status and serum albumin levels were also positively correlated with selenium concentrations.
  • Environmental factors: Environmental factors like mercury levels in the surrounding ecosystem can influence selenium bioaccumulation in certain species like European perch. This suggests that environmental pollution may also be another factor affecting human selenium status.

Optimizing Selenium Levels

There are two main ways to improve your selenium levels: through dietary changes and with supplements.

Dietary Changes

  • Eat Brazil nuts: A single Brazil nut can provide more than the recommended daily intake of selenium. However, it’s important to be moderate as too much selenium can be toxic.
  • Incorporate other selenium-rich foods: Fish, poultry, eggs, whole grains, and some meats are all good sources of selenium.

Supplements

  • Talk to your doctor: Before taking any supplements, discuss it with your doctor. They can advise you on the appropriate dosage based on your individual needs and test for any deficiencies to determine if supplementation is necessary.

Important to Remember

  • Don’t overdo it: While selenium is an important mineral, too much can be harmful. It’s important to follow your doctor’s advice regarding supplements and avoid exceeding the recommended daily intake from both food and supplements.
  • Consult a doctor: If you suspect a selenium deficiency, it’s important to see a doctor for proper diagnosis and treatment. They can perform a blood test to measure your selenium levels.

Where is Phosphorus Found?

Phosphorus, a cornerstone of life, can be found in various geological and biological reservoirs, intricately woven into the fabric of Earth’s ecosystems. Predominantly sourced from phosphate rocks, phosphorus deposits are scattered globally, with notable concentrations in regions like North Africa, China, Russia, and the United States.

Geologically, phosphorus primarily resides in phosphate minerals, such as apatite. Weathering of these rocks over eons releases phosphorus into the soil, initiating a crucial cycle for sustaining life. Within ecosystems, phosphorus cycles through the lithosphere, hydrosphere, and biosphere, manifesting in soils, sediments, and living organisms.

Water bodies serve as reservoirs for dissolved phosphorus, a key player in aquatic ecosystems. Its abundance influences the growth of aquatic plants and algae, shaping the dynamics of freshwater and marine environments.

In agriculture, phosphorus fertilizers derived from phosphate rocks replenish soil phosphorus levels, enhancing crop growth and ensuring global food security. However, the careful management of phosphorus usage is imperative to mitigate environmental concerns like eutrophication, emphasizing the delicate balance between necessity and ecological impact.

Why Does the Body Need Phosphorus?

Phosphorus, an elemental mineral, is indispensable to the human body for a myriad of essential physiological functions. Constituting a vital component of DNA, RNA, and ATP, phosphorus is fundamental to the genetic coding and energy transfer processes within cells. Its presence in bones and teeth, primarily as hydroxyapatite, imparts structural integrity and strength.

Phosphorus plays a pivotal role in the cellular machinery, facilitating the synthesis of proteins and enzymes crucial for metabolic activities. As a key component of cell membranes, it contributes to cellular signaling and transport processes. Additionally, phosphorus is involved in the regulation of pH balance, participating in acid-base buffering systems within bodily fluids.

The body maintains phosphorus homeostasis through a delicate balance of absorption from the gastrointestinal tract, renal excretion, and bone resorption. Adequate dietary intake is imperative for maintaining optimal health, with sources encompassing various foods like dairy products, meat, fish, and nuts.

Deficiency or excess of phosphorus can lead to disruptions in bone metabolism, impaired energy production, and compromised cellular function. The intricate orchestration of phosphorus within the human body underscores its critical role in sustaining life and highlights the importance of maintaining a balanced intake for overall well-being.

What Can Affect Phosphorus Levels?

Genetic Factors

Phosphorus, a vital mineral for cellular energy and bone health, is regulated by a complex interplay of ion transporters and hormones. A recent study involving 16,264 participants of European ancestry explored the genetic factors influencing serum phosphorus levels. The researchers conducted a genome-wide association study, identifying seven genetic loci associated with phosphorus concentration. 

Notably, three of these loci were near genes (SLC34A1, CASR, and FGF23) related to kidney-specific sodium phosphate transport, calcium-sensing, and fibroblast growth factor 23—key players in phosphorus metabolism. Additionally, genes encoding phosphatases, kinases, and phosphodiesterases were implicated, suggesting roles in phosphorus homeostasis.

The study underscores the importance of genetic variation in regulating phosphorus levels in the general population. Dysregulated phosphorus metabolism can have clinical consequences, including vascular calcification and increased cardiovascular risk.

The findings provide valuable insights into the genetic underpinnings of phosphorus regulation, paving the way for further research into potential mechanisms and therapeutic targets. This large-scale genome-wide association study represents a significant step toward understanding the heritable aspects of serum phosphorus concentration and its health implications.

Environmental Factors

Environmental factors play a crucial role in influencing phosphorus levels in the human body, impacting both intake and absorption. Understanding these factors is vital for maintaining phosphorus homeostasis and preventing imbalances that can adversely affect health.

  1. Dietary Intake: The primary source of phosphorus for the human body is the diet. Foods rich in phosphorus include dairy products, meat, fish, nuts, and whole grains. Variations in dietary habits directly influence phosphorus intake, with vegetarian diets potentially leading to lower phosphorus levels compared to omnivorous diets. Conversely, excessive consumption of phosphorus-rich processed foods, especially those containing phosphoric acid, can contribute to elevated levels.
  2. Calcium-Phosphorus Ratio: The interaction between phosphorus and calcium is critical for bone health. An imbalance in the calcium-phosphorus ratio can affect the absorption of both minerals. High intake of phosphorus relative to calcium may lead to increased parathyroid hormone (PTH) secretion, promoting the release of calcium from bones and potentially disrupting bone metabolism.
  3. Vitamin D Status: Vitamin D facilitates the absorption of phosphorus in the intestines. Inadequate sunlight exposure or insufficient dietary intake of vitamin D can impair phosphorus absorption, potentially leading to lower phosphorus levels. Conversely, excessive vitamin D intake can increase phosphorus absorption, contributing to hyperphosphatemia.
  4. Renal Function: The kidneys play a crucial role in regulating phosphorus levels by excreting excess phosphorus in the urine. Individuals with compromised renal function may experience difficulty eliminating phosphorus, leading to elevated levels in the blood. Chronic kidney disease (CKD) is particularly associated with disturbances in phosphorus homeostasis, contributing to mineral and bone disorders.
  5. Medications: Certain medications can influence phosphorus levels. Phosphate-containing laxatives, antacids, and some diuretics may contribute to increased phosphorus intake. On the other hand, medications used in the treatment of hyperphosphatemia, such as phosphate binders, can reduce phosphorus absorption.
  6. Physical Activity and Metabolism: Increased physical activity and metabolism can impact phosphorus utilization. Athletes and individuals with higher metabolic rates may experience greater phosphorus turnover, necessitating an increased dietary intake to meet the body’s demands. Conversely, sedentary lifestyles may influence phosphorus requirements.
  7. Age and Growth: Phosphorus needs vary across life stages. Infants, children, and adolescents have higher requirements for phosphorus due to growth and bone development. Aging adults, particularly postmenopausal women, may experience changes in phosphorus metabolism and absorption, affecting bone health.
  8. Gastrointestinal Disorders: Conditions affecting the gastrointestinal tract, such as malabsorption disorders (e.g., celiac disease, inflammatory bowel disease), can impact the absorption of phosphorus. Individuals with these disorders may require dietary adjustments or supplementation to maintain adequate phosphorus levels.

Understanding the intricate interplay of these environmental factors is essential for promoting optimal phosphorus levels in the human body and preventing the potential health complications associated with imbalances. Regular monitoring, a balanced diet, and consideration of individual health conditions are key components of maintaining phosphorus homeostasis.

Understanding and Optimizing DHA Levels

Aira on August 12, 2024

Overview

Docosahexaenoic acid (DHA) is a type of omega-3 fatty acid vital for our health, and DHA levels in our bodies play a significant role in our overall well-being.

This long-chain fatty acid is a crucial component of cell membranes throughout the body and plays a significant role in transmitting messages between nerves.

DHA is naturally produced in small quantities by our bodies, but to achieve adequate amounts, DHA needs to be obtained through dietary sources or supplements. Dietary sources of DHA include cold-water fish, such as salmon, mackerel, and trout. It is also available as a supplement, such as via fish oil preparations.

Life DNA

Importance of DHA in Wellness

Our body’s ability to work well is closely linked to our DHA levels. This important omega-3 fatty acid is key to keeping our essential bodily processes balanced. The following are some of its fundamental contributions.

Cellular Health

DHA is a crucial component of the membrane of each cell in our body. It helps maintain the fluidity and permeability of cell membranes, which is essential for the proper functioning of cells.

Brain Function

DHA levels are especially high in the brain and the retina (eye). Researchers are actively investigating the possible benefits of DHA in preventing or treating a variety of brain and eye-related conditions.

Heart Health

DHA and another omega-3 fatty acid called eicosapentaenoic acid (EPA) may help reduce inflammation and your risk of chronic diseases, such as heart disease. Some studies suggest that DHA may be more effective than EPA at improving several markers of heart health.

Maintaining adequate levels of DHA in the body is essential for optimal health and well-being. It can be obtained through dietary sources or supplements, ensuring that our bodies function at their best.

Genetics of DHA Levels

The DHA levels in our body can be influenced by various genetic factors. This section will explore the specific genes that may affect DHA levels.

FADS1 and FADS2 Genes

The FADS1 and FADS2 genes encode desaturase enzymes. These enzymes play a crucial role in converting dietary alpha-linolenic acid (ALA) into DHA. Single nucleotide polymorphisms (SNPs); variations at a single position in the DNA sequence within these genes can influence the efficiency of this conversion process. For instance, minor alleles of SNPs in FADS1 (such as rs174548) and FADS2 were associated with higher levels of ALA and lower levels of DHA.

ELOVL2 Gene

The ELOVL2 gene encodes an enzyme known as elongase. This enzyme is involved in the extension of the carbon chain of fatty acids, a critical step in the production of DHA. Variations in the ELOVL2 gene can influence the levels of DHA in the body. For example, minor alleles of the SNP rs2236212 in ELOVL2 were associated with higher levels of DHA.

Interaction of FADS1, FADS2, and ELOVL2 Genes with Dietary Intake

Interestingly, the impact of these genetic variations on DHA levels may also affect the effect of the dietary intake of omega-3 fatty acids. For instance, in individuals with certain genetic variants in the FADS1 and FADS2 genes, dietary supplementation with fish oil led to a greater increase in DHA levels compared to those without these variants. This suggests that the effect of diet on DHA levels can be moderated by our genetics.

In conclusion, our genetics, particularly variations in the FADS1, FADS2, and ELOVL2 genes, can significantly influence the levels of DHA in our body. Understanding these genetic influences can provide valuable insights into how we can optimize our DHA levels for better health.

Non-Genetic Factors Influencing DHA Levels

Aside from genetics, several factors, such as our diet and lifestyle, can impact the DHA levels in our bodies. Understanding these influences is key to ensuring we maintain the right levels of this important omega-3 fatty acid for our overall well-being.

Dietary Intake

Boosting DHA levels in the body is most directly achieved through dietary intake. Incorporating foods rich in DHA, such as cold-water fish like salmon, mackerel, and trout, along with nuts, seeds, and certain plant oils, can significantly contribute to meeting this essential omega-3 fatty acid requirement. Additionally, fish oil supplements serve as another convenient source of DHA.

Lifestyle

Lifestyle factors such as physical activity and alcohol consumption can also impact DHA levels. Regular exercise can help improve the body’s utilization of DHA, while excessive alcohol can interfere with DHA absorption.

Health Status

Various health conditions can impact DHA levels in the body. For example, individuals with diabetes may experience changes in the metabolism of DHA. Additionally, conditions affecting fat absorption, like Crohn’s disease, can also influence DHA levels.

Age and Sex

DHA levels can be influenced by age and gender. Women often have higher DHA levels than men, possibly due to the effects of estrogen. Moreover, DHA levels tend to decrease with age, emphasizing the dynamic nature of these levels as we grow older.

How To Boost DHA Levels

Improving the DHA levels in our body involves a combination of dietary changes and lifestyle modifications. Here are some strategies that can help:

  • Increase Omega-3 Intake

Consuming EPA and DHA directly from foods and/or dietary supplements is the only practical way to increase the levels of these fatty acids in the body. Foods rich in DHA include cold-water fish like salmon, mackerel, and trout. Algal oil, a plant-based source of DHA, is also an option, especially for vegetarians and vegans.

  • Limit Omega-6 Intake

While omega-6 fatty acids are essential for health, a high ratio of omega-6 to omega-3 in the diet can inhibit the conversion of ALA to DHA. Therefore, try to balance your intake of these fatty acids by reducing the consumption of omega-6-rich foods such as vegetable oils and processed foods.

  • Regular Exercise

Regular physical activity can help improve the body’s utilization of DHA. It also helps control blood sugar levels and lowers the risk of heart disease, which is beneficial for overall health.

  • Adequate Hydration

Dehydration can cause blood sugar levels to spike, which can affect the metabolism of DHA. Therefore, it’s important to stay well-hydrated.

  • Limit Alcohol Consumption

Excessive alcohol can interfere with DHA absorption. It’s advisable to limit alcohol intake to moderate levels as defined by health guidelines.

  • Avoid Smoking

Smoking can hurt overall health and may interfere with the absorption and utilization of essential nutrients, including DHA.

The Genetics Of Antioxidants

Aira on August 12, 2024

What Are Antioxidants?

Antioxidants are molecules that neutralize free radicals in the body. Free radicals are compounds that can cause harm if their levels become too high. They come from various sources, including food, medicines, tobacco smoke, radiation, and various biological processes of the body.

Genetics Of Antioxidants

What Do Antioxidants Do?

Free radicals are unstable atoms that can damage cells, thus contributing to aging and diseases. Antioxidants neutralize these harmful free radicals, preventing cellular and DNA damage. The body has its system of providing antioxidants but also sources them from our diet – primarily through fruits, vegetables, and certain types of meat and fish.

According to the National Center for Complementary and Integrative Health, dietary antioxidants include:

Are Antioxidants Good for You?

Generally, a balanced diet rich in fruits and vegetables – good sources of antioxidants – is most beneficial. Studies show a strong correlation between a diet rich in antioxidants and a reduced risk of chronic diseases like heart disease, cancer, and neurodegenerative diseases.

Protection Against Reactive Oxygen Species

At the cellular level, metabolic processes generate reactive oxygen species (ROS), potentially harmful molecules capable of damaging cellular components, including DNA, proteins, and lipids. Over time, organisms developed antioxidant systems as a defense mechanism against ROS. These systems help maintain cellular integrity and function.

Mitochondrial Function

Mitochondria, often referred to as the powerhouses of the cell, play a critical role in making energy for the cells. While essential for life, this process also produces ROS as a byproduct. Antioxidants help protect mitochondria from ROS-induced damage, ensuring efficient energy production and cellular survival.

Adaptation and Survival

In evolutionary history, environmental stress factors, such as exposure to high radiation levels from the sun, could lead to increased ROS production. Organisms with effective antioxidant systems had a survival advantage, as they could better manage oxidative stress, leading to improved cellular function, DNA integrity, and overall survival.

Complex Antioxidant Systems

Evolution favored organisms with diverse antioxidants, enabling them to respond to various oxidative challenges. This is evident in various antioxidant systems in modern organisms, including enzymes like superoxide dismutase, catalase, and glutathione peroxidase and non-enzymatic molecules like vitamins C, E, and beta-carotene.

Antioxidant-rich Diets and Human Evolution

As early human diets were rich in fruits, vegetables, and other plant-based foods, the intake of dietary antioxidants likely played a role in human evolution. A diet rich in antioxidants could have protected against oxidative stress, supporting overall health, longevity, and reproductive success.

Vitamin C as an Antioxidant

Vitamin C, also known as ascorbic acid, is a potent antioxidant to safeguard against oxidative stress. It also plays a role in collagen production, wound healing, and maintaining cartilage, bones, and teeth. Fruits like oranges, strawberries, and kiwi are abundant sources of vitamin C.

Genetics of Antioxidant Status

Our genetic makeup plays a vital role in determining our body’s antioxidant status, influencing the production of natural antioxidants and the response to antioxidants obtained from dietary sources. A deeper understanding of this relationship has emerged from studying gene polymorphisms related to antioxidant enzymes and their respective functions.

Several genes encoding for antioxidant enzymes have been identified, and their polymorphisms can have profound implications for health and susceptibility to oxidative stress:

SOD (Superoxide Dismutase)

Superoxide dismutases (SODs) are special enzymes in all life forms, from bacteria to humans. Their main job is to protect cells from harmful ROS. Think of ROS as tiny invaders that can harm our cells. SODs defend against these invaders by breaking down a harmful ROS called the superoxide anion free radical (O2-). They convert this harmful molecule into two less harmful substances: regular oxygen that we breathe and hydrogen peroxide. By doing this, SODs help maintain a balance in our cells and prevent excessive amounts of damaging ROS from accumulating.

Different genes encode the three forms of SOD (SOD1, SOD2, SOD3), and polymorphisms in these genes can influence antioxidant capacity. The SOD2 gene polymorphism, Ala16Val (rs4880), in exon 2 is well-studied. This particular single nucleotide polymorphism (SNP) swaps the amino acid at the 16th position from valine (Val) to alanine (Ala). Numerous studies have linked the Ala16Val SNP with variations in the SOD2 enzyme activity, influencing disease progression and risk, including this 2016 meta-analysis. 

CAT (Catalase)

The CAT gene encodes for the enzyme catalase, which helps convert hydrogen peroxide, a potential ROS, into water and oxygen. A lack or dysfunction of catalase is theorized to contribute to the onset of several age-related conditions, including cancer, diabetes mellitus, hypertension, anemia, Alzheimer’s disease, Parkinson’s disease, and other chronic conditions such as vitiligo, bipolar disorder, and schizophrenia.

Variations in the CAT gene can lead to differing levels of catalase enzyme activity in the body. A 2016 meta-analysis reviewed the correlation between two prevalent catalase gene polymorphisms (rs1001179 and rs794316) and cancer risk. This analysis encompassed 37 published studies, totaling 14,942 cancer patients and 43,285 individuals without cancer.  Both polymorphisms were associated with an increased cancer risk.

GPX (Glutathione Peroxidase)

This family of enzymes, particularly GPX1, encodes the GPx-1 protein. GPx-1 targets hydrogen peroxide, a molecule that can cause damage to our bodies. GPx-1 converts hydrogen peroxide into water. Specific polymorphisms in the GPX1 gene can affect the activity of the GPx-1 protein and, subsequently, the body’s ability to neutralize ROS.

The GPX1 polymorphism Pro198Leu genotype was examined in 82 individuals with prostate cancer and 123 controls. The researchers identified a protective effect from the variant Leu allele of the GPX1 polymorphism against the risk of prostate cancer. Individuals heterozygous for the variant Leu allele exhibited a notably reduced risk of prostate cancer compared to those homozygous for the wild-type.

GST (Glutathione S-transferase)

GST enzymes, encoded by the GST family of genes like GSTM1 and GSTT1, assist in detoxifying and neutralizing certain oxidants. Deletions or null polymorphisms in these genes are associated with reduced enzyme activity and increased susceptibility to oxidative stress-related conditions.

A meta-analysis study indicated that individuals possessing the GSTM1 null genotype, or having both GSTM1 and GSTT1 null genotypes, or those with the GSTT1 null genotype in combination with the GSTP1 A131G variation are at an increased risk of developing prostate cancer.

A 2018 study showed that the absence of the GSTM1 gene was related to a greater likelihood of colorectal cancer spreading to the lymph nodes. The same study also demonstrated that variation in the GSTT1 gene was linked to a higher severity of tumors in colorectal cancer patients.

Does Genetics Influence Your Thyroid Function?

Aira on August 12, 2024

Overview

What is a Thyroid?

Who would have thought that an organ much smaller than the palm of your hand could affect so much of your bodily functions? The small, butterfly-shaped gland nestled at the base of your neck orchestrating a symphony of metabolic functions within your body is called a thyroid. It is a crucial endocrine gland that plays a pivotal role in regulating metabolism, energy production, and overall growth and development.

Anatomy and Function

The thyroid gland, situated just below the Adam’s apple, produces essential hormones that influence nearly every cell in the human body. T3 (triiodothyronine) and T4 (thyroxine), the thyroid hormones, meticulously control the body’s metabolic rate, impacting processes such as heart rate, body temperature, and energy expenditure. This intricate control is orchestrated by the hypothalamus and pituitary gland, forming a complex feedback loop known as the hypothalamic-pituitary-thyroid (HPT) axis.

What is the Function of a Thyroid?

Controlled by the sophisticated HPT axis, the thyroid’s activity is orchestrated by the release of thyrotropin-releasing hormone (TRH) from the hypothalamus and thyroid-stimulating hormone (TSH) from the pituitary gland. This intricate system ensures precise regulation of thyroid hormone secretion based on the body’s metabolic demands.

Thyroid hormones influence various tissues and organs that are essential for normal growth and development, particularly in the central nervous system and skeletal development. Aberrations in thyroid function, whether hypo- or hyperthyroidism, can lead to a spectrum of health issues, underscoring the critical role this gland plays in maintaining overall physiological balance and homeostasis. Understanding the nuanced functions of the thyroid provides a foundation for comprehending the complexities of metabolic regulation in the human body.

Does Genetics Influence Your Thyroid Function?

Are Humans the Only Ones with a Thyroid?

No, humans are not the only organisms with a thyroid; the thyroid gland is present in a wide range of vertebrates, emphasizing its evolutionary significance. The thyroid gland is a fundamental component of the endocrine system, and its structural and functional homologs exist in various animal species.

Other mammals, including non-human primates, share a similar thyroid anatomy and function with humans. Also, birds possess a thyroid gland situated near their trachea, playing a crucial role in regulating metabolism and growth. Reptiles also exhibit thyroid function, influencing their metabolism and reproductive cycles. Fish, amphibians, and even some invertebrates have thyroid-like structures that contribute to hormonal regulation within their respective physiological systems.

The conservation of thyroid glands across diverse species underscores the evolutionary importance of this endocrine organ. While variations exist in the specifics of thyroid anatomy and hormone production, the overarching function of regulating metabolism and maintaining physiological balance remains a common thread throughout the animal kingdom.

What Can Affect Thyroid Function?

There are many things, both internal and external to the human body, that may affect thyroid function. Delving into the genetics of thyroid function unveils a fascinating interplay between inherited factors and environmental influences. Genetic variations can predispose individuals to thyroid disorders, such as hypothyroidism or hyperthyroidism. Understanding these genetic and environmental intricacies is not only pivotal for comprehending the roots of thyroid-related conditions but also holds the promise of personalized approaches to diagnosis and treatment.

Genetic Factors

Genetic factors play an important role in a person’s thyroid function. While genetics are not the sole determinant of a healthy, well-functioning thyroid, some genes have been linked to better or worse thyroid function.

Thyroid-stimulating hormone (TSH) orchestrates thyroid function by binding to its receptor (TSHR), triggering cyclic AMP (cAMP) production. Serum TSH levels serve as a sensitive gauge of thyroid health, and anomalies impact approximately 10% of individuals over a lifetime. 

In a recent study examining genetic data from over 16,000 individuals, common variants linked to TSH and free thyroxine (FT4) level variation were explored. For TSH, a new variant in SYN2 (rs310763) and an independent variant in PDE8B (rs470397) were identified. SYN2, a protein involved in neurotransmitter regulation, and PDE8B, associated with cyclic AMP production, play key roles in thyroid regulation. For FT4 levels, a low-frequency variant near B4GALT6/SLC25A52 was found, tagging a rare TTR variant linked to ceramide metabolism and cyclic AMP inhibition in thyroid-stimulated cells.

These findings highlight the complex factors influencing thyroid traits, contributing to our understanding of normal thyroid function. The study demonstrates the importance of analyzing both common and rare genetic variants to uncover novel associations with thyroid function. 

In another study with 4,300 Sardinians, a significant association between a genetic variant (rs4704397) in PDE8B, a gene encoding a cAMP-specific phosphodiesterase, and circulating TSH levels was found notably, PDE8B variants were implicated in altering cAMP levels in the thyroid, influencing the production of T4 and T3 and, in turn, impacting TSH release from the pituitary. This positions PDE8B as a potential target for interventions in thyroid dysfunction. 

These findings illuminate the genetic factors influencing TSH levels, providing insights into thyroid physiology and the potential modulation of thyroid disease progression. The genome scans have also highlighted associations with several other genes like PDE10A, TSHR, THRB, GNAQ, TG, POU1F1, PDE4D, and TSHR.

Environmental Factors

The thyroid gland can be influenced by a variety of environmental factors that may impact its function. Understanding these influences is essential, as alterations in thyroid function can lead to a spectrum of health issues. Here are some key environmental factors known to affect thyroid function:

  1. Iodine Availability: Iodine is an indispensable component for thyroid hormone synthesis. Insufficient iodine intake can lead to iodine deficiency disorders, such as goiter and cretinism. Conversely, excessive iodine intake, often seen in areas with iodine-rich diets or due to iodine-containing medications, can also disrupt thyroid function, potentially triggering hyperthyroidism or hypothyroidism.
  2. Endocrine Disruptors: Certain environmental contaminants, or endocrine disruptors, can interfere with thyroid hormone production and regulation. Chemicals like perchlorate, found in some fertilizers and drinking water, can competitively inhibit iodine uptake by the thyroid, affecting hormone synthesis. Bisphenol A (BPA), present in plastics, has also been linked to thyroid dysfunction by disrupting hormone signaling pathways.
  3. Heavy Metals: Exposure to heavy metals, such as mercury, lead, and cadmium, can adversely affect thyroid function. Mercury, often found in contaminated fish, can interfere with thyroid hormone synthesis and lead to autoimmune thyroiditis. Lead exposure has been associated with decreased thyroid hormone levels, particularly in children, impacting cognitive development.
  4. Radiation Exposure: Ionizing radiation, whether from medical procedures, environmental sources, or nuclear accidents, poses a risk to thyroid health. The thyroid is highly sensitive to radiation, and exposure can result in an increased risk of thyroid cancer and other thyroid disorders. This was notably observed following the Chernobyl nuclear disaster.
  5. Stress: Chronic stress can influence the hypothalamic-pituitary-thyroid (HPT) axis, disrupting the normal feedback loop and leading to alterations in thyroid hormone levels. Stress-induced changes in cortisol levels may also impact thyroid function indirectly. While the relationship between stress and thyroid function is complex, studies suggest a potential link between chronic stress and thyroid disorders.
  6. Dietary Factors: Nutritional factors, beyond iodine, play a role in thyroid health. Selenium, for example, is a crucial micronutrient involved in the conversion of T4 to the active T3 hormone. Deficiencies in selenium can impair this conversion, affecting overall thyroid function. Additionally, certain foods, known as goitrogens, can interfere with iodine utilization and may impact thyroid hormone production.

Understanding the intricate interplay between environmental factors and thyroid function provides valuable insights into preventive measures and potential interventions to maintain optimal thyroid health. Regular monitoring and addressing environmental influences are essential aspects of comprehensive thyroid care.

How Do You Measure Thyroid Levels?

Measuring thyroid levels is a crucial aspect of assessing thyroid function and identifying potential disorders. The primary indicators analyzed are the levels of thyroid hormones (T3 and T4) and thyroid-stimulating hormone (TSH) in the blood.

  • TSH Levels: Thyroid-stimulating hormone, produced by the pituitary gland, stimulates the thyroid to release T3 and T4. Elevated TSH levels typically indicate an underactive thyroid (hypothyroidism), as the body attempts to stimulate more hormone production. Conversely, low TSH levels may suggest an overactive thyroid (hyperthyroidism).
  • T3 and T4 Levels: Triiodothyronine (T3) and thyroxine (T4) are the thyroid hormones responsible for regulating metabolism. Abnormalities in their levels can indicate thyroid dysfunction. High T3 and T4 levels may be associated with hyperthyroidism, while low levels can indicate hypothyroidism.
  • Thyroid Antibodies: Testing for thyroid antibodies, such as anti-thyroid peroxidase (TPO) and anti-thyroglobulin antibodies, helps identify autoimmune thyroid conditions like Hashimoto’s thyroiditis or Graves’ disease.
  • Thyroid Imaging: In certain cases, imaging techniques like ultrasound or scintigraphy may be employed to assess the physical structure of the thyroid gland. This is particularly useful in identifying nodules, inflammation, or abnormalities.
  • Reverse T3 (rT3): While less commonly measured, reverse T3 can provide additional insights into thyroid function. It is the inactive form of T3 and may be elevated in certain conditions, reflecting altered thyroid hormone conversion.

These laboratory tests, collectively known as thyroid function tests, provide a comprehensive profile of thyroid health. Interpretation involves considering the interplay between TSH, T3, and T4 levels, along with clinical symptoms and potential underlying causes. Regular monitoring of thyroid levels is crucial for individuals with thyroid disorders or those at risk, enabling timely interventions and personalized management strategies.

Acute symptoms of zinc toxicity include nausea, vomiting, loss of appetite, and abdominal cramps. Long-term consumption of excessively high zinc levels can impair immune function, disrupt copper absorption, and cause deficiencies in other essential minerals.

Chronic exposure to elevated zinc concentrations may lead to metal fume fever, a condition characterized by fever, chills, and respiratory distress, commonly observed in industrial settings where workers inhale zinc-containing fumes.

Topical application of zinc, often used in sunscreens and creams, is generally safe. However, some individuals may experience skin irritation or allergic reactions. Inhaling zinc oxide nanoparticles, especially in occupational settings, may pose respiratory risks.

As with any nutrient, moderation is key, and individuals with specific health conditions or those considering zinc supplementation should consult healthcare professionals to ensure optimal intake without compromising overall health.

What is the Suggested Daily Intake of Zinc?

The recommended daily intake of zinc varies based on age, sex, and life stage. 

Adults: For adult males aged 19 years and above, the recommended dietary allowance (RDA) is 11 mg per day, while adult females in the same age group require slightly less at 8 mg per day. 

Pregnant and Lactating Individuals: During pregnancy, the RDA increases to 11 mg, emphasizing the heightened need for zinc to support both maternal and fetal health. Lactating women have a higher RDA of 12 mg per day to meet the demands of breastfeeding.

Children: Children have different recommended levels: 2 mg for infants aged 7-12 months, 3 mg for children aged 1-3 years, 5 mg for those aged 4-8 years, and 8 mg for children aged 9-13 years.

These recommendations are established by health authorities such as the National Institutes of Health (NIH) and are intended to ensure adequate zinc intake for the normal growth, development, and maintenance of physiological functions. 

While these values serve as general guidelines, individual variations, dietary patterns, and health conditions may warrant adjustments. Individuals need to maintain a balanced diet with diverse zinc sources, including meat, dairy, nuts, and legumes, to meet their specific nutritional needs.

What are the Symptoms of Zinc Deficiency and Zinc Overdose?

Taking the right amount of zinc every day can help lessen your chances of developing zinc deficiency or going into zinc overdose. Should you constantly lack or exceed zinc intake, visit a healthcare professional if symptoms arise. Some of the symptoms of zinc deficiency and zinc overdose are listed below.

Zinc Deficiency Symptoms

  • Impaired Growth and Development: Zinc is crucial for cellular growth and division. Inadequate zinc levels can result in stunted growth, delayed sexual maturation, and developmental issues, particularly in children.
  • Weakened Immune Function: Zinc plays a pivotal role in the immune response. Deficient individuals may experience more frequent infections, prolonged illnesses, and difficulty recovering from infections.
  • Skin Disorders: Skin manifestations include dermatitis, eczema, and hair loss. These symptoms are attributed to the role of zinc in skin health, immune function, and wound healing.
  • Gastrointestinal Issues: Zinc deficiency can lead to gastrointestinal problems such as diarrhea and impaired absorption of nutrients, contributing to a cycle of malnutrition.
  • Impaired Cognitive Function: Zinc is involved in neurotransmitter regulation, and its deficiency may result in impaired cognitive function, affecting memory and concentration.
  • Reproductive Issues: In both men and women, zinc deficiency can impact fertility. In men, it may lead to reduced sperm quality, while women may experience menstrual irregularities.
  • Loss of Appetite: Zinc deficiency is associated with a diminished sense of taste and smell, leading to a decreased appetite and potential weight loss.

Zinc Overdose Symptoms

  • Nausea and Vomiting: Acute zinc toxicity can lead to gastrointestinal distress, with symptoms like nausea, vomiting, and abdominal cramps.
  • Lowered Immune Function: Paradoxically, excessive zinc intake can suppress immune function. This can result in increased susceptibility to infections and a compromised immune response.
  • Copper Deficiency: High zinc levels can interfere with copper absorption, leading to copper deficiency. Symptoms include anemia, fatigue, and neurological issues.
  • Gastrointestinal Disruption: Chronic zinc overdose may cause gastrointestinal issues such as diarrhea and abdominal pain. These symptoms often prompt individuals to reduce zinc intake.
  • Headache and Dizziness: Neurological symptoms, including headache and dizziness, can occur with zinc overdose. These symptoms may subside upon reducing zinc intake.
  • Impaired Iron Absorption: Excessive zinc can inhibit iron absorption, contributing to iron deficiency anemia. This is particularly relevant in populations where iron intake is already a concern.
  • Metal Fume Fever: Inhalation of high levels of zinc-containing fumes, often in industrial settings, can cause metal fume fever. Symptoms include fever, chills, and respiratory distress.

Balancing zinc intake is crucial to prevent both deficiency and toxicity. Consulting healthcare professionals for guidance on appropriate zinc levels, especially when considering supplementation, is essential to maintaining optimal health.

How to Maintain Adequate Levels of Zinc

Maintaining adequate levels of zinc is paramount for overall health, given its integral role in numerous physiological processes. A balanced approach, incorporating dietary choices, supplementation when necessary, and mindful lifestyle habits, can ensure optimal zinc levels.

Here’s a comprehensive guide to achieving and sustaining adequate zinc intake.

Diverse Diet

Embrace a diet rich in zinc-containing foods. Animal sources like meat, poultry, fish, and dairy provide highly bioavailable forms of zinc. Plant-based sources such as nuts, seeds, legumes, and whole grains contribute to overall zinc intake. Varied dietary choices help mitigate the impact of potential inhibitors like phytates found in some plant foods, promoting effective zinc absorption.

Consideration of Bioavailability

Be mindful of zinc bioavailability, as not all forms of zinc in food are equally absorbable. Animal sources typically provide zinc in a more readily absorbable form compared to plant sources. Cooking methods, such as soaking and fermenting, can enhance the bioavailability of zinc in certain plant foods.

Avoid Excessive Iron Intake

High iron intake, particularly from supplements, can interfere with zinc absorption. While iron is essential, balance is crucial. If iron supplementation is necessary, it’s advisable to monitor zinc levels and, if needed, adjust zinc intake accordingly.

Moderate Phytate Intake

Phytates, present in certain plant foods, can hinder zinc absorption. However, these foods also offer essential nutrients. Balancing the intake of phytate-rich foods with zinc-rich options and employing food preparation techniques that reduce phytate levels can help maintain adequate zinc absorption.

Limit Alcohol Consumption

Excessive alcohol intake can compromise zinc status by impairing absorption and increasing urinary zinc excretion. Moderating alcohol consumption is beneficial for overall health and aids in maintaining optimal zinc levels.

Regular Monitoring for At-Risk Groups

Certain groups, including pregnant and lactating women, infants, and individuals with gastrointestinal disorders, are at an increased risk of zinc deficiency. Regular monitoring of zinc levels through blood tests can help identify potential deficiencies early, allowing for timely interventions.

Choose Zinc-Rich Supplements Wisely

Supplements can be beneficial for individuals at risk of zinc deficiency, but their use should be approached judiciously. Choosing supplements with forms of zinc that have good bioavailability, such as zinc picolinate or zinc citrate, is important. Consultation with healthcare professionals is advisable to determine the appropriate dosage and duration.

Optimal Water Source

While water is not a primary source of zinc, using clean and uncontaminated water ensures that the body receives zinc without additional unwanted elements. Water purification methods should be considered in areas with known water quality issues.

Sunscreen with Caution

Zinc oxide is a common ingredient in sunscreens, offering protection against UV radiation. While this topical application is generally safe, individuals with sensitive skin should be cautious, and proper cleansing after sun exposure can prevent prolonged zinc exposure.

Maintaining adequate levels of zinc involves a holistic approach that combines dietary diversity, mindful food choices, and lifestyle considerations. Tailoring strategies based on individual needs and regularly assessing zinc status can help individuals achieve and sustain optimal zinc levels, supporting overall health and well-being.
