What is Snacking Behavior?

Aira on October 22, 2023

What is Snacking Behavior?

Snacking behavior refers to the consumption of food and drinks other than main meals – breakfast, lunch, and dinner. The small meals or bites we take between our primary meals can range from a piece of fruit to a handful of chips.

Why Do People Snack? The Biology

Snacking is an integral part of many people’s dietary habits. But beyond the mere act of consuming food between meals, the biological reasons for snacking provide an intriguing insight into our body’s inner workings and the evolutionary pressures that shaped them.

Hunger and Satiety Mechanisms

The primary biological reason for snacking is due to our body’s hunger and satiety mechanisms. The hypothalamus in the brain plays a critical role in regulating these mechanisms. It responds to signals from hormones like ghrelin, which stimulates hunger, and leptin, which signals satiety. When our energy levels drop, ghrelin production increases, prompting us to seek out food. Conversely, our leptin levels rise after we have eaten, signaling that we have had enough.

Blood Sugar Regulation

Blood sugar levels can also influence snacking. When blood sugar drops, the body seeks a quick source of energy. Carbohydrate-rich snacks, for example, can rapidly boost blood sugar levels, alleviating feelings of hunger or fatigue. But, consistently relying on sugary snacks can lead to peaks and troughs in blood sugar, increasing the urge to snack frequently.

We will discuss this cycle of hunger and satiety in more detail in our blog on the Genetics of Appetite.

Metabolic Rate Variations

Everyone’s metabolism is slightly different from others’. Some people have faster metabolic rates, meaning they burn calories more quickly and might feel hungry more often. In contrast, those with a slower metabolic rate may not feel the need to snack as much.

Evolutionary Perspective

From an evolutionary standpoint, our ancestors did not always have the luxury of regular meals. Snacking, or eating whenever food was available, was crucial for survival. Our modern snacking behavior might be a trace of this “eat when you can” approach, a biological drive to ensure we have enough energy stored for times of scarcity.

Brain Reward System

Beyond pure physiological hunger, the brain’s reward system also plays a role in snacking. Foods, especially those rich in sugar, salt, and fat, can stimulate the release of dopamine, a neurotransmitter associated with pleasure and reward. Over time, we might seek out snacks more to experience the pleasurable feeling associated with certain foods than to satiate hunger.

Section Summary

The biology of snacking is a complex interplay of physiological needs, metabolic processes, and brain chemistry, all influenced by our evolutionary history. Understanding these factors can provide insights into our modern dietary habits and how to make healthier snacking choices.

Genetics of Snacking Behavior

The predisposition of some individuals to snack more frequently or prefer certain types of snacks might be genetic. Scientists have recently identified several genes that might influence snacking habits.

FTO Gene

The FTO gene, often labeled as the “obesity gene,” is one of the most extensively studied genes concerning eating habits and weight management. Variants of this gene are linked to increased calorie intake and a preference for high-calorie foods. Individuals with specific variants of the FTO gene might find it more challenging to resist calorie-dense snacks.

For example, individuals harboring the “A” allele of SNP rs9939609 are less likely to feel satiated or full after eating. This reduced sensation of fullness can lead to increased food intake, potentially contributing to weight gain or obesity over time.

In a fascinating study published in 2017, researchers observed the consumption of advertised food in children. When subjected to food advertisements, the children consumed an average of 48 kCals more of the recently advertised food than their peers who watched toy advertisements. Interestingly, the consumption of the recently advertised food related to viewing food advertisements increased linearly with every additional FTO risk allele (“A” allele in SNP rs9939609) present in the individual.

MC4R Gene

The MC4R gene encodes the melanocortin 4 (MC4) receptor, which interacts with alpha-melanocyte-stimulating hormone (a-MSH). Predominantly found in the brain’s hypothalamus region, this receptor plays a pivotal role in regulating food consumption, metabolic processes, and reproductive behaviors, among other functions.

Variants of this gene can influence feelings of satiety, which means individuals with specific mutations might feel hungry sooner after a meal, leading to more frequent snacking. In a study involving participants from various European nations, the rs17782313 “C” variant was linked to heightened feelings of hunger, increased snacking tendencies, and the consumption of larger food quantities.

In another study on 5724 women, the risk allele C of rs17782313 was significantly associated with higher intakes of total energy and dietary fat.

In a recent study on 151 Chinese children and their parents, individuals carrying the MC4R rs12970134 “A” variant displayed a heightened inclination towards food and had a higher intake of beverages.

DRD2 Gene

The DRD2 gene stands for dopamine receptor D2 and encodes the D2 subtype of the dopamine receptor. D2 receptor plays a significant role in the neurotransmission of dopamine, a crucial neurotransmitter involved in pleasure, reward, and motivation, among other functions. People with specific variants of the DRD2 gene might derive more pleasure from eating, which can translate to more frequent snacking or a preference for pleasurable, often unhealthy, snacks.

A 2018 study investigated the association of DRD2 Taq1A, Taq1B, and Taq1D gene polymorphisms with eating behavior, the preference/intake frequency/craving of high-fat foods, and obesity in 394 Malaysian adults. Participants carrying the A1 or B1 allele demonstrated a lower Cognitive Restraint score and a higher Uncontrolled Eating score. Additionally, those with the A1/A1 or B1/B1 genotype strongly preferred fast food.

DRD2 gene variants also influence binge eating disorder, bulimia nervosa, and other substance abuse issues.

BDNF Gene

The BDNF gene encodes for the brain-derived neurotrophic factor (BDNF) protein. BDNF is a member of the neurotrophin family of growth factors and plays a critical role in the development, maintenance, and plasticity of the central and peripheral nervous systems. Some research suggests a potential connection between BDNF and eating behaviors. Specific variants in the BDNF gene are associated with anorexia nervosa and other eating disorders.

As per a 2021 study comparing patients with anorexia nervosa to healthy controls, the serum BDNF levels in the patients were slightly lower upon admission. However, these levels steadily rose as time progressed, surpassing those in healthy controls at the 2.5-year mark. At discharge, they found a negative correlation between BDNF levels and the severity of eating disorder symptoms.

LEP Gene

The LEP gene codes for leptin, a hormone predominantly produced in adipose (fat) cells. It plays a crucial role in regulating appetite, energy expenditure, and body weight. Variations in the LEP gene and its receptor (LEPR) have been of interest in numerous studies investigating obesity and eating behaviors.

A 2021 article on the genetic and molecular examined the evidence supporting the influence of the hormones leptin and ghrelin on snacking. The article highlighted that individuals with the genotype CT of the rs791607 SNP had a tendency for higher snack consumption.

LEPR Gene

The LEPR gene is associated with the leptin receptor and regulates body weight, energy balance, and appetite. Leptin is a hormone that signals the brain to reduce appetite when energy stores (in body fat) are sufficient.

Early GWAS studies on the LEPR gene established the significant influence of intronic G/A variant rs2025804 on body mass index (BMI). Another study showed that individuals with the risk variant of rs2025804 had the propensity for higher BMI and lower energy. And more recently a 2022 cross-sectional study observed that carriers of the “G” allele of this variant had a tendency for extreme snacking behavior.

PLIN1 Gene

The PLIN1 gene (Perilipin 1) regulates lipid storage and metabolism in adipocytes (fat cells). While its primary function revolves around lipid metabolism, several studies have looked into its potential association with obesity and related eating behaviors, such as snacking. Variations in this gene influence how individuals metabolize and store fat from snacks. It means two individuals consuming the same fatty snack might store that fat differently based on their PLIN1 gene variation.

Section Summary

While genetics can provide insight into our potential snacking behaviors, it’s essential to remember that genes are not destiny. Environmental factors, personal choices, and lifestyle are crucial in shaping our eating habits.

Evolutionary Significance of Snacking

Evolutionary biologists posit that our ancestors, the hunter-gatherers, used to eat multiple small meals throughout the day based on food availability. This approach ensured they had the energy to hunt and gather effectively. Further, the ability to ingest more energy than you expend was beneficial because it allows for energy (fat) storage that may be required in times of food scarcity.

Non-Genetic Factors Influencing Snacking Behavior

Beyond genetics, several non-genetic factors influence our snacking habits:

Emotional State: Stress, boredom, or emotional distress can lead to comfort eating or emotional snacking.

Social Environment: Peer pressure or societal norms can influence snacking. For instance, group settings might make some consume more snacks than alone.

Accessibility: The easier it is to access snacks, especially unhealthy ones, the more likely people are to consume them.

Ideas for Healthy Snacks

Not all snacking is bad. Healthy snacking can provide essential nutrients and keep energy levels stable. Here are some nutritious snack ideas:

A handful of nuts.
Greek yogurt with berries.
Baby carrots with hummus.
Apple slices with almond butter.
Whole-grain crackers with cheese.

Can Snacking be a Good Habit?

Whether snacking is a ‘good’ habit depends mainly on what and how much you’re eating. Healthy snacks in moderation can balance blood sugar levels, provide essential nutrients, and prevent overeating at mealtimes. However, excessive or unhealthy snacking can lead to weight gain and other health issues.

Is Lactose Tolerance Genetic and What the Research Tells Us

Aira on September 1, 2023

How many people do you know can’t drink milk or consume anything with dairy because it “doesn’t agree with them”? While the effects of lactose may vary from person to person, they can all agree that lactose intolerance can be uncomfortable, if not downright painful. Nowadays, nutritional genetic testing lets you know if your DNA is more likely to make you lactose intolerant.

What Is Lactose Tolerance?

Lactose intolerance is a condition in which the body cannot fully digest lactose, a sugar found in milk and milk byproducts. This is due to the lack of an enzyme called lactase in the small intestine. As a result of this malabsorption, consuming dairy may cause bloating, gassiness, and diarrhea.

Some people who are lactose intolerant can still consume dairy products in small amounts, while others need to eliminate lactose from their diet completely. It all depends on how badly the symptoms manifest for an individual and what their healthcare provider recommends

Some tests can be done to determine if you are lactose intolerant. The hydrogen breath test and the lactose intolerance test are two of the most common methods healthcare professionals use to determine if an individual has this condition.

The hydrogen breath test is done by making an individual drink a liquid with plenty of lactose and then measuring the hydrogen levels in their breath afterward. Too much hydrogen means you are lactose intolerant.

The lactose intolerance test makes you drink a liquid with high levels of lactose, and then your blood will be drawn two hours later to see if glucose levels rose. If glucose remains the same, your body is not digesting lactose, and you are intolerant.

Note that lactose intolerance is not the same as milk allergy. A dairy allergy, or milk allergy, occurs when the immune system overreacts to the presence of proteins in milk. Symptoms may include swelling, breathing problems, and anaphylaxis. Lactose intolerance, on the other hand, is not an allergy because it does not involve the immune system but instead the body’s lack of ability to digest dairy properly.

Top 7 FAQs About Lactose Intolerance

Today, we’re answering your most frequently asked questions about lactose intolerance

Who Is Most Likely To Have Lactose Intolerance?

While children and younger adults are less likely to be lactose intolerant, they can still develop the condition at a later age. Some health experts even view lactose intolerance as a natural condition of the human body that is related to aging, rather than being a serious condition that needs to be treated. Apart from age, ethnic background may also be a factor for individuals with lactose intolerance.

How Long Do Symptoms of Lactose Intolerance Last?

Symptoms of lactose intolerance usually manifest anytime between 30 minutes to 2 hours after an individual has consumed dairy. They can last for up to 48 hours, depending on how much dairy is consumed.

Does Lactose Intolerance Cause Constipation?

Apart from the typical symptoms of bloating, flatulence, diarrhea, and abdominal pain, a good number of cases of lactose intolerance also have constipation as a symptom. This particular symptom can also be as uncomfortable and painful as diarrhea.

What Happens If You Ignore Lactose Intolerance?

Lactose intolerance is usually harmless if the symptoms are only mild to moderate. Some people have symptoms that are mild enough to be ignored. Thus, they continue to consume dairy in moderate amounts. Lactose intolerance symptoms can vary in severity, but if you suspect you have severe digestive problems, contact your primary care physician immediately.

Can You Reverse Lactose Intolerance?

If lactose intolerance is caused by an underlying condition, getting treatment for the pre-existing disease might help alleviate the symptoms of lactose intolerance, if not completely restore the body’s ability to digest the lactose. However, if lack of lactase causes the symptoms, there is not much an individual can do except manage their symptoms and avoid dairy.

Can Stress Cause Lactose Intolerance?

Researchers have long seen a link between gastric and digestive problems and mental and psychological issues. According to these experts, stomach problems may have little to do with what an individual has consumed and more to do with anxiety, stress, depression, and other psychological conditions.

What Is The Genetic Basis of Lactose Intolerance In Humans?

Does Genetics Affect Lactose Intolerance?

Yes, lactose intolerance can be influenced by your DNA. For people who consume dairy with genetic lactose sensitivity, there may be excess gas, pain, and other digestive problems. One of the genes we analyze for your lactose tolerance is your MCM6 gene. Discover your genetic likelihood of lactose intolerance today based on DNA with our LifeDNA Nutrition Report .

LCT Gene

Variations affecting the LCT gene, which encodes the lactase enzyme, are the main contributors to lactose intolerance. The enzyme lactase converts lactose, a sugar present in milk and dairy products, into glucose and galactose, two sugars that can be absorbed by the body.

MCM6 Gene

One of the main genetic polymorphisms linked to lactase persistence, or the capacity to digest lactose into adulthood, is the MCM6 gene (SNP rs4988235). On chromosome 2, the MCM6 gene is next to the LCT (Lactase) gene and has regulatory components that affect how the LCT gene is expressed. The rs4988235 SNP, which is specifically positioned in an enhancer region of the MCM6 gene, affects the expression of the nearby LCT gene, which in turn affects lactase synthesis.

The “T” allele of rs4988235 is linked to lactase persistence, which means that people who possess this allele are more likely to produce lactase enzyme throughout adulthood and have the capacity to digest lactose without feeling too uncomfortable. Particularly in areas where dairy products have been a dietary mainstay for decades, this allele is frequently discovered in cultures with a history of dairy production and consumption.

The “C” allele of rs4988235, on the other hand, is linked to lactase non-persistence, which indicates that people who have this allele experience a decline in lactase synthesis during childhood, resulting in lower lactose digestion and a higher chance of experiencing the symptoms of lactose intolerance.

The SNP rs4988235 in MCM6 gene region is the most extensively researched and well-known variation (also known as the LCT T-13910C polymorphism) that impacts lactase expression. It is the main variant that has been thoroughly studied and connected to lactase persistence, while other genetic variations for example in the MCM6 or LCT genes that affect this feature may exist. Genetic differences connected to lactase persistence may vary throughout groups, and the interaction between these variations can lead to varied levels of lactase activity and lactose tolerance.

An individual’s genotype at the rs4988235 locus can be determined by genetic testing, and this information can reveal whether they are likely to be lactase persistent (and lactose tolerant) or not. However, as heredity only accounts for a small portion of lactose intolerance, environmental variables and cultural customs can significantly affect a person’s actual tolerance to lactose-containing foods.

To avoid uncomfortable symptoms, people with the lactase non-persistence SNP may need to limit their dairy intake. Consuming lactose-free dairy products, taking lactase enzyme supplements prior to consuming dairy, or selecting dairy substitutes are all ways to manage lactose sensitivity.

How To Manage Lactose Intolerance

A lactose-free diet is more relaxed than it sounds. Fruits, vegetables, meat, poultry, seafood, soy products, whole grains, nuts, and healthy fats can still be fully enjoyed by lactose-intolerant individuals. As a precaution, consult with your doctor before making any major changes in your diet.

Additionally, be extra careful when consuming dairy and dairy-based products. Try the elimination diet and slowly reintroduce dairy products in small amounts into your diet and see how much is too much and what moderate means. You can also find dairy alternatives such as plant-based products and byproducts but make sure you are still getting your daily recommended dose of calcium.

Making dietary and lifestyle decisions that reduce the discomfort and symptoms brought on by consuming lactose-containing foods is essential to managing lactose intolerance. Here are some recommendations for managing lactose intolerance:

Pick out the trigger foods. Keep a list of the foods and drinks that make you feel unwell. While some people with lactose intolerance are able to handle modest doses of lactose, others must completely avoid it. To find out how much dairy you can tolerate, try out various dairy products.
Select lactose-free dairy products. Lactose-free versions of dairy goods like milk, cheese, yogurt, and ice cream are widely available in grocery shops. These goods have had the lactose removed or broken down, which makes them simpler to digest.
Try dairy substitutes. Investigate non-dairy substitutes such as oat or rice-based lactose-free products, soy milk, coconut milk, and almond milk. To assist satisfy your nutritional needs, make sure to choose alternatives that are fortified with calcium and vitamin D.
Step by step raise intake. Over time, some people who are lactose intolerant can tolerate modest doses of lactose. Incorporate dairy products into your diet gradually to see how your body reacts to them.
Take supplements with the lactase enzyme. You can buy supplements containing the lactase enzyme over-the-counter to aid in the digestion of lactose. Take these before consuming foods or beverages that contain lactose.
Recognize hidden lactose. Unexpected sources of lactose include processed foods, baked products, salad dressings, and some medicines. Keep an eye out for hidden sources of lactose by reading labels carefully.
Speak with your primary care physician or a registered dietitian. Consider speaking with a certified dietitian if you’re unsure how to manage your lactose intolerance or are worried about receiving enough nutrition. They can assist you in developing a healthy, lactose-free diet plan.

Keep in mind that everyone has a different level of tolerance, so what works for one person might not work for another. Finding a strategy that works for your body and lifestyle while yet meeting your nutritional needs is crucial.

DHA Levels Based on DNA: Omega 3 deficiency

Aira on March 20, 2023

If you’re a big fan of fish and other seafood, you have probably looked up their health benefits and already know they are a good source of beneficial nutrients such as Omega-3 fatty acids.

Omega-3 fatty acids have a wide range of health benefits, including reduced risk of inflammatory diseases and heart disease. One of the Omega-3 fatty acids is Docosahexaenoic acid, more commonly known as DHA.

Much like Omega-3, DHA can be found in oily fish and has a myriad of scientifically-backed health benefits. On its own, DHA can support your brain function and improve your eye health. This fatty acid can also help your muscles recover faster from exercise, reduce certain types of cancers from developing, and support overall blood circulation.

How Genetics Can Affect DHA Metabolism

Depending on your DNA, your body may have a reduced or increased metabolism for DHA. This means that your body may be able to synthesize less or more DHA or absorb less or more DHA from your diet and from supplements.

Although your body can produce DHA, it does so in minimal doses via other fatty acids already present. If you want to make your DHA levels higher, taking this fatty acid via food or supplements might help. People commonly take DHA supplements or eat food rich in this fatty acid to lower high levels of cholesterol and other bad fats that might pose a health risk

Genetic testing for deficiency can help reveal your DHA levels LifeDNA offers a wide range of DNA plans to help you get started on your personalized wellness journey.

DHA and Cardiovascular Support

As you may already know, DHA supports overall cardiovascular health. Omega-3 fatty acids, including DHA, can help lower blood pressure. You may probably wonder, “do Omega-3s lower cholesterol?” According to some studies, Omega-3 containing DHA and EPA may also reduce blood cholesterol as an added supplement.

However, it is important to note that DHA supplements cannot and should not replace medication that your physician prescribes for conditions such as high blood pressure and high cholesterol levels.

Symptoms of omega 3 deficiency

It is important that you consume enough Omega-3 fatty acids in order to maintain optimal wellness.

Without adequate DHA in your body, you may be at an increased risk of a compromised immune system, as well as suboptimal pulmonary, endocrine, and cardiovascular health.

In fact, some studies have found that a lack of Omega-3 fatty acids in the body has been associated with several conditions such as:

Skin and eye dryness and irritation
Depression or depressive episodes
Pain and stiffness of the muscles and joints

To boost your DHA levels, optimizing your diet can definitely help! Including more fatty fish such as salmon and cod, as well as nuts high in precursors of DHA can also help boost your DHA levels.

If you suspect that your body is not able to synthesize or absorb DHA efficiently and effectively, a DNA test for a potential nutrient insufficiency might help. LifeDNA can provide full and comprehensive information on hundreds of unique traits based on your genetic variation.

Genetic testing for vitamin deficiency

Remember, LifeDNA offers a Vitamins Report that provides insights into your body’s potential deficiencies for certain vitamins and minerals, as well as suggestions on how you can improve your lifestyle and supplementation based on your result.

Genetic testing for nutrition and food allergies

Aira on February 10, 2023

While you may not experience it first-hand, you most likely have witnessed someone or know someone who has allergies. Allergies, in general, are the body’s immune response to certain environmental factors that are otherwise harmless to other people. These triggers are known as allergens and can come in the form of food, dust mites, pollen, animal hair, medication, and others. This immuno-response may vary from mild and manageable to severe and life-threatening.

What is Food Allergy? Food allergens elicit the same response from your immune system if your allergies are triggered. Depending on how allergic you are to a particular food, even the tiniest amount of it can trigger allergic reactions. Food allergies can occur almost immediately and up to 2 hours after an individual has eaten an allergen.

The Role of Genetics in Food Allergies

As many studies have shown, food allergies can be genetic. Your DNA can impact your likelihood of developing allergies toward peanuts, peaches, and even shrimps.

Genetic testing for nutrition

Thanks to technological advances, people can now get a personalized nutrition DNA analysis to see if they are susceptible to food allergies. LifeDNA can provide a full and comprehensive Nutrition Report that includes insights on food allergies and sensitivities, vitamin deficiencies, and other wellness factors based on your DNA.

If you’re ready to get personalized insights into your DNA, get your Nutrition Report today.

Today, we’ll answer some of the most common questions about certain food allergies:

What is peanut allergy?

Peanut allergy is one of the most common causes of anaphylaxis. While commonly mistaken for tree nuts, peanuts are actually part of the legume family. They are grouped together with lentils, beans, and soy. A peanut allergy happens when your immune system sees peanut proteins as harmful substances to the body and violently reacts to counter them.

Why are peanut allergies so common?

Millions of children suffer from peanut allergies but adults can also have them. While studies show that over 20 percent of children outgrow this food allergy, its effects can still vary from mild to severe.

Are peanut allergies genetic?

One study showed that some parts of the DNA harbor genes that are linked to peanut allergies. This study suggests that these genes pose a significant genetic risk from parent to child, although no conclusive data are available to this day as research continues.

Peanut Allergy Test

Peanut allergies can be detected via a blood test called an immunocap radioallergosorbent (RAST). This test checks the number of immuno-response cells in your blood called antibodies. The higher the antibodies after a controlled food intake, the higher the chances you might be allergic to it.

What is peach allergy?

Peaches belong to the family of apricots, cherries, plums, and almonds. Their edible flesh is sought-after because of their sweet-tangy taste. However, some are allergic to peaches. The two types of peach allergies are those that have birch-pollen allergies and those that have non-birch-pollen allergies.

Birch-pollen allergies are caused by the body mistaking peach protein similar to birch protein which causes birch-pollen allergies. This type of protein cannot survive heat and cooking so people with this type can eat cooked or processed peaches.

Non-birch-pollen allergies are caused by eating the flesh and peel which contains a protein present in peaches. They are tough and can survive heat, thus, people with this type of allergy cannot consume peaches in any form.

Peach allergy symptoms

Like most food allergies, symptoms of peach allergy can vary from mild to severe. They also include symptoms such as rashes, gastrointestinal problems, and anaphylaxis. Peach allergy may also include symptoms of Oral Allergy Syndrome (OAS) including an itchy mouth, swollen tongue, and scratchy throat.

Peach Allergy Test A peach allergy test can be done via a skin test or blood test. An oral challenge is making the patient take a certain amount of peaches and then test for antibodies. This is only done for those without severe allergic history to peaches. The prick-prick test is also another test; it is done by pricking a lancet into a peach and pricking the same lancet through the individual’s skin. Any adverse reaction will merit a positive result in peach allergies.

What is shrimp allergy?

Shellfish allergy is an allergy to proteins in certain edible marine animals such as crustaceans and mollusks. These include crabs, shrimps, lobsters, squid, oysters, scallops, and other shellfish. Symptoms may also vary from mild to severe.

Shrimp Allergy Test

Allergy testing for shrimp allergy can be done the same way as peach allergy testing. A blood test or skin prick tests are two options widely available for shrimp allergy test results. The process is the same; either oral intake of shellfish and then a blood test for antigens or prick shellfish proteins and prick the human skin for any reactions.

When to see a doctor

Food allergies are more common than you might think. If any allergic reaction takes place after eating a certain food, immediately take note of its intensity and take due course of action. See your primary care physician if these symptoms start to manifest more frequently or if they increase in intensity. Emergency cases such as anaphylaxis should be treated immediately and given first-aid medications such as epinephrine injections.

Food sensitivity test: Is gluten bad for you?

Aira on February 8, 2023

Gluten is a kind of natural protein that can be found in wheat, barley, rye, and other grains. It is found in many common food and drinks such as dough, pasta, cereal, beer, and even some types of medicines. Too bad for you if you love pizza and carbonara and turns out you have gluten sensitivity. Even food without naturally occurring gluten can still be contaminated if they are processed in factories that also handle grains or otter food that contains gluten.

Gluten acts like a binder, giving food a solid bond and that “stretchy” texture. For example, a dough without gluten cannot be kneaded and hand-tossed without a gluten substitute because it can easily rip apart. While a gluten-free diet may need extra planning and paying attention to nutritional labels, it is possible and millions of people have switched to it, even those without gluten sensitivity issues because of the supposed health benefits it can give you.

What is Gluten Sensitivity?

Gluten sensitivity, also sometimes known as non-Celiac gluten sensitivity (NCGS) or gluten intolerance, is when you get sick after eating food or drinks that contain gluten. Symptoms of gluten sensitivity may range from occasionally passing gas to locking yourself up in the toilet for hours. These symptoms can manifest anytime from after eating the gluten-containing food up to several days. Signs of gluten sensitivity may include:

Gastrointestinal issues such as abdominal pain, diarrhea, and irritable bowel syndrome
Bloating and flatulence
Unexpected fatigue or brain fog
Nausea and vomiting
Joint and muscle pain
Skin rashes or hives

Genetics and Gluten Sensitivity

Gluten sensitivity can be influenced by your DNA. Since gluten sensitivity is highly related to food allergies, we have analyzed genetic variants that are linked with allergenic reactions including the varied HLA and MYO9B genes.

Benefits of trying out a food sensitivity test

Doing genetic testing with LifeDNA for personalized nutrition can tell you what your gluten needs (or lack thereof) and you can start from there. A comprehensive nutritional genetic testing on your gluten sensitivities may help with managing your symptoms, identifying potential gluten triggers and avoiding them, as well as reducing your risk of adverse reactions to gluten-containing food and beverages.

LifeDNA can provide a full and comprehensive Nutritional Report that includes gluten sensitivities, food allergies, vitamin deficiencies, and other health factors based on your personalized nutrition test

What causes gluten sensitivity?

Gluten sensitivity is not to be confused with gluten allergy. Simply speaking, food sensitivities or intolerances affect the digestive system while food allergies are triggered by the immune system. Gluten sensitivity is more common than you might think and affects people of all ages. Some people are born with gluten sensitivity while others develop them with age.

Diagnosing Gluten Sensitivity

To diagnose gluten sensitivity, your primary care physician may ask you to go on a gluten-free diet for a certain period of time, usually for more or less six weeks to rule out Celiac disease or wheat allergies. They might also perform blood tests and skin tests. The former is to see how your immune system will react to wheat proteins and the former is a prick test of wheat protein on an area of your skin for adverse reactions.

Celiac Disease vs. Gluten Sensitivity

Gluten sensitivity vs. Celiac disease has long been lumped together because of the similar symptoms they cause. The two, however, are two different conditions. Celiac disease is an autoimmune condition caused by an abnormal gene wherein the body’s response to gluten is to treat it as if it were an invading virus. With this condition, your tissues eat at your gut (small intestines) whenever you ingest gluten, causing much inflammation and damage to your digestive tract.

While gluten sensitivity can become uncomfortable and sometimes downright painful, it is generally considered a less serious condition compared to Celiac disease. Gluten sensitivity also isn’t caused by abnormal genes, although they can be genetic.

Can gluten sensitivity cause hair loss?

Gluten doesn’t directly cause hair loss but there are studies that show gluten can influence hair loss. Celiac disease has hair loss listed as a symptom and because gluten is related to this condition, gluten might aggravate the hair loss situation, especially if you have been diagnosed with Celiac disease.

Can gluten sensitivity cause acne?

While gluten’s relation to Celiac disease can be linked to several skin conditions, there is no scientific evidence that gluten can cause acne. No studies have shown that gluten triggers acne either so you might want to go easy on the spot treatment after eating a burger for dinner.

Plus, did you know that acne can also be influenced by your DNA? Some people are more likely to develop severe acne as compared to others.

Lactose: Food tolerance testing based on DNA

Aira on February 3, 2023

How many people do you know can’t drink milk or anything with dairy in it because it “doesn’t agree with them”? While the effects of lactose may vary from person to person, they can all agree that lactose intolerance can be uncomfortable, if not downright painful. Nowadays, nutritional genetic testing lets you know if your DNA is more likely to make you lactose intolerant.

What is Lactose Tolerance?

Lactose intolerance is a condition in which the body is unable to fully digest lactose, a sugar found in milk and milk byproducts. This is due to the lack of an enzyme called lactase in the small intestine. As a result of this malabsorption, consuming dairy may cause bloating, gassiness, and diarrhea.

Some people who are lactose intolerant can still consume dairy products in small amounts while others need to completely eliminate lactose from their diet. It all depends on how badly the symptoms manifest for an individual and what their healthcare provider says about it.

Some tests can be done to determine if you are lactose intolerant. The hydrogen breath test and the lactose intolerance test are two of the most common methods used by healthcare professionals to determine if an individual has this condition.

The lactose intolerance test makes you drink a liquid with high levels of lactose and then your blood will be drawn two hours later to see if glucose levels rose. If glucose remains the same, this means your body is not digesting the lactose in the liquid and you are intolerant.

Top 7 FAQs About Lactose Intolerance

Today, we’re answering your most frequently asked questions about lactose intolerance.

Does genetics affect lactose intolerance?

Who is most likely to have lactose intolerance?

While children and younger adults are less likely to be lactose intolerant, they can still develop the condition at a later age. Some health experts even view lactose intolerance as a natural condition of the human body rather than a serious condition that needs to be treated. Apart from age, ethnic background may also be a factor for individuals with lactose intolerance.

How long does lactose intolerance last?

Symptoms of lactose intolerance usually manifest anytime between 30 minutes to 2 hours after an individual has consumed dairy. They can last for up to 48 hours depending on how much dairy was consumed.

Does lactose intolerance cause constipation?

Apart from the typical symptoms of bloating, flatulence, diarrhea, and abdominal pain, a good number of cases of lactose intolerance also has constipation as a symptom. This particular symptom can also be as uncomfortable and painful as diarrhea.

What happens if you ignore lactose intolerance?

Lactose intolerance is usually harmless if the symptoms that manifest are only mild to moderate. Some people have symptoms that are mild enough to be ignored, thus, they continue to consume dairy in moderate amounts. Lactose symptoms can vary in severity but if you suspect that you have severe digestive problems, contact your primary care physician immediately.

Can you reverse lactose intolerance?

If lactose intolerance is caused by an underlying condition, getting treatment for the pre-existing disease might help alleviate the symptoms of lactose intolerance, if not completely restore the body’s ability to digest the enzyme. However, if lactose intolerance is caused by the lack of lactase, there is not much an individual can do except manage their symptoms and avoid dairy.

Does lactose intolerance get worse with age?

It is not uncommon for people to suddenly develop lactose intolerance. This condition can either be primary and congenital or secondary and developmental. The former is hereditary and passed down via genetics while the latter is caused by decreased lactase in the body. Secondary lactose intolerance can occur at any age but is more likely to occur at a later age.

Can stress cause lactose intolerance?

Researchers have long found a link between gastric and digestive problems with mental and psychological issues. According to these experts, stomach problems may have little to do with what an individual has consumed and more with anxiety, stress, depression, and other psychological conditions.

Discover your body’s lactose tolerance levels and get genetic testing for personalized nutrition today with LifeDNA’s most updated and detailed nutrition reports.

LifeDNA’s Genetic Testing for Food Intolerance

LifeDNA offers a non-invasive test for food tolerance testing. This genetic testing is done via a saliva sample and analyzed by the best scientific labs.

We also offer a DNA upload option to make it easier for people who have already taken a test to optimize their wellness with LifeDNA.

How to Manage Lactose Intolerance

A lactose-free diet is not as restrictive as it sounds. Fruits, vegetables, meat, poultry, seafood, soy products, whole grains, nuts, and healthy fats can still be fully enjoyed by lactose-intolerant individuals. Just a precaution, be sure to consult with your doctor first before making any major changes in your diet. Additionally, be extra careful when consuming dairy and dairy-based products. Try the elimination diet and slowly reintroduce dairy products in small amounts into your diet and see how much is too much and what moderate means. You can also find dairy alternatives such as plant-based products and byproducts. Thinking about doing genetic analysis to discover what foods work best for you and your unique body?

Genetic testing for vitamin deficiency: B12

Aira on January 31, 2023

If you are a health buff, or even just someone who casually watches out for their vitamin and mineral intake, you would know that Vitamin B is essential for your body. There is not only one Vitamin B but eight types of Vitamin Bs. These B-group vitamins are water-soluble vitamins that are necessary for the body to complete certain metabolic processes.

How Important is Vitamin B12 to Your Overall Health?

The human body does not make Vitamin B12 on its own. You have to either get it from certain foods or from supplements. There is a certain amount of Vitamin B12 that is recommended daily for the human body depending on factors such as age, body weight, and diet.

Luckily, plenty of food commonly contains Vitamins B1, B6, B9, B12, and others. Some examples of food with Vitamin B are eggs, red meat, soy products, nuts and seeds, and shellfish. Some Vitamin B12 vegetables and fruits include dark, leafy greens, potatoes, mushrooms, bananas, apples, and berries.

Does Genetics Affect Vitamin B Levels?

The deficiency of Vitamin B12 can be linked to genetic factors, as well as lifestyle, dietary, environmental, and other intrinsic factors. While these studies are still premature in their scientific evidence, technological advancement in DNA testing for vitamin deficiency has greatly helped those affected by decreasing or deficient Vitamin B levels.

Want to know if you have a higher risk of Vitamin B-12 deficiency based on your DNA? Find out now with LifeDNA’s Vitamins Report – available for free when you get your Nutrition Report today.

Does Vitamin B12 give you energy?

The B-group vitamins in general help your body convert the food you eat into glucose, which is then converted into energy for you to go about your daily tasks. Vitamin B12 is said to aid in a number of processes including the production of red blood cells, the production of elements for DNA to be formed, and the overall health of the nervous system.

What are Vitamin B12 benefits for hair?

Vitamin B12 deficiency is often linked to hair loss and thinning of hair as symptoms of anemia. While Vitamin B12 does not prevent hair problems nor solve them, they are known to help in the production of red blood cells, which then carry oxygen to the hair follicles for hair health. A deficiency in Vitamin B12 may increase your likelihood of

LifeDNA’s Genetic Testing for Vitamin Deficiency

LifeDNA offers personalized wellness insights based on the latest research in order to provide you with the most accurate results when it comes to vitamin deficiency. LifeDNA’s diet and health pack includes a personalized Vitamin Report and over 40 unique trait reports on:

Vitamin B Levels
Vitamin D Levels
Thyroid Functions
Liver Enzyme Levels
Biotin Levels
…and so much more!

What is too much Vitamin B12?

Your body’s B12 levels are essential for your overall health and well-being. According to the NIH, the recommended daily dose of Vitamin B12 for adults is 2.4 mcg but consuming more than that is your safest bet, the body absorbs what it needs and the rest gets secreted via urine because B vitamins are water-soluble.

The tolerable upper intake level for those suffering from a B12 deficiency is up to 1000 mcg per day. Discover your Vitamins B Levels today based on your DNA with LifeDNA’s most powerful nutrition and vitamin reports.

How to Manage Vitamin B Deficiency

Some people find it easy to manage their Vitamin B deficiency by making dietary and lifestyle changes. Others turn to B12 supplements after talking to their primary care physician. The bottom line is, Vitamin B12 deficiency is manageable if it is detected and addressed early on.

The Genetics of Food Sensitivities: How LifeDNA’s DNA Analysis Can Help You Identify and Manage Adverse Reactions to Certain Foods

Aira on January 20, 2023

How many times have you eaten something, thinking it was good food not to be wasted, and ended up paying for it hours later in the bathroom? Your body’s reaction might not be all that alarming apart from a bit of gas, belching, bloating, or maybe moderate irritable bowel syndrome (IBS). Still, it can get pretty uncomfortable, if not downright painful.

Knowing what food triggers these reactions in your body will help in managing the symptoms or even eradicate them. Apart from the try-it-and-test-it method of ruling out which food to avoid or eat more of (others consider this is the best test for food sensitivities while others think it is unnecessary if not scientifically tested), a food sensitivity test can be done via DNA analysis. LifeDNA offers a comprehensive DNA nutrition analysis for individuals who want to start optimizing their diet and wellness.

What is Food Sensitivity?

Food sensitivity is also sometimes called food intolerance. Some experts separate their definitions but many lump them together. Food sensitivity is the body’s reaction to food that cannot be digested or digested at a much slower rate than usual by the digestive system. This might be due to your body’s lack of enzymes to digest a certain food. Simply put, when you are sensitive to a certain food, symptoms can arise – symptoms that can make you uneasy, uncomfortable, and even cause pain.

Some of the most common food sensitivities symptoms can include excessive gas, bloating, diarrhea, constipation, nausea, vomiting, and stomach cramps. Not to be confused with food allergies, almost always, the symptoms are digestive-related and that’s how many identify food sensitivities. Food allergies may vary in severity and affect the immune system, which when left untreated, can become a serious health issue and even life-threatening.

Can My Genetics Affect Food Sensitivity?

Over the years, there have been multiple studies that suggest DNA may play a role in our food allergies and sensitivities. This only suggests that looking into your DNA can provide a wide array of information about an individual’s well-being.

Using LifeDNA’s personalized nutrition analysis, your nutritional needs, food sensitivities, your body’s needs for unique vitamins and minerals, as well as its ability to digest lactose and tolerate gluten can be revealed. Your DNA can greatly help you achieve optimal nutrition.

How Can LifeDNA’s Genetic Testing Help with Food Sensitivity?

LifeDNA’s genetic testing can generate personalized nutrition tests for individuals. Our popular nutrition DNA analysis can allow you to use your existing DNA test results to discover what foods would work best for your unique body based on DNA.

Why do I have so many food sensitivities?

An individual can have multiple food sensitivities. If this is the case for you, no need to panic yet as many food sensitivities can be treated or managed. One of the most common food intolerance is lactose intolerance and it can often be managed by taking Lactaid pills or other kinds of medicine to help relieve you of symptoms.

How Can I Manage My Food Sensitivities?

Food sensitivity may vary in severity from person to person. Managing them usually entails taking a closer look at your diet, changes in lifestyle, and sometimes taking medications that can help relieve symptoms and discomfort. It is important to consult first with your primary care physician when going on diets that may affect your overall health and well-being. Food journaling may also help you keep track of what food triggers your intolerance and what keeps them at bay.

Understanding and managing food sensitivities can help prevent you from potentially developing more serious health-related problems down the road.

Are You More Likely To Binge Eat Based On DNA?

Aira on November 10, 2022

People may tend to overeat from time to time.

However, binge eating is a different matter. If you always eat a large amount of food in a brief period of time, even when you are not hungry, you’re probably binge-eating.

When you’re binge-eating. you’re also more likely to feel embarrassed or guilty about it.

Your genetics play a significant role in your diet and health, particularly your eating habits. LifeDNA has found 5 important genes that can influence your likelihood of binge-eating.

What is considered binge-eating?

Binge-eating and overeating both include mindless activity. You eat excessively without considering why.

However, there are significant differences.

Here are some examples of overeating:

Enjoying multiple desserts after dinner
Consuming an entire bag of popcorn while watching a movie

Here are some examples of binge-eating:

Consuming two or three burgers even when you’re already stuffed.
Eating to the point of pain.
Eating a whole cake in one sitting and then feeling guilty.

Your FTO Gene & Your Natural Eating Habits

A variety of genes influence your likelihood of binge eating. These genes have the potential to influence brain circuits that regulate hunger and mood.

One of the genes that our geneticists have looked into is your FTO gene

Your FTO gene is also linked to other traits such as:

Saturated Fat Metabolism

How quickly do you metabolize saturated fats?

Satiety

Trouble feeling full? Ask your DNA.

Appetite

Appetite determines how much you naturally want to eat.

Preference for fatty foods

The food you love to eat is heavily determined by your genetics.

And weight change

Research suggests that for some people, genes account for 25% of their predisposition to be overweight/underweight, while for others, the genetic influence is as high as 70% to 80%.

Want to get personalized diet insights tailored to your DNA? Check out our nutrition report now.

Certain genetic variants may increase your likelihood of binge eating, but other factors including your lifestyle and environment can also trigger it.

Other external factors that can affect your binge-eating tendencies

Parents and families.

If you often see your parents overeat, you’re more likely to pick up these behaviors. The practices you acquire from the people around you may have an impact on your eating habits.

Anxiety and Stress.

People tend to binge eat after going through a serious, stressful situation. It is important to note that emotional eating is not always a sign of binge eating.

Depression.

Depression may increase your likelihood of binge-eating. In fact, about 50% of people who tend to binge eat are also depressed.

Excessive calorie restriction.

An attempt to shed a few pounds might sometimes result in binge eating. This is particularly true when people try to lose weight by cutting meals or consuming too little. If they don’t attain their target weight, they may feel so bad about themselves that they overeat.

If you want to lose weight, the best DNA test will help you do that based on the way your own, individual body works.

Final Thoughts

Binge-eating can lead to obesity, which is a risk factor for many diseases.

That’s why it’s important to know your genetic predisposition to binge eating in order to get the right prevention management from health care professionals.
