The Ultimate Beginners Guide To Nutrigenomics: How To DNA Test For Nutrition and Health

What Is Nutrigenomics And What Is The Point Of Nutrigenomic Testing?

Nutrigenomics is a field of genetics that helps in determining the nutritional requirements of an individual based on their genetic makeup. 

Nutrigenomics also aims to identify genetic susceptibility to diseases and the ways in which very small difference in our genes can alter the effects that nutrient intake has on the body.

Nutrigenomic testing is at the forefront of personalized medicine.  

We are all very unique, and DNA testing allows us to gain a greater understanding of our unique biochemistry, so that we can optimize health and prevent disease.

Our individual genetic make-up controls what we can and can’t digest, our tendency to gain weight, absorb important nutrients and cope with toxins.

By knowing our individual tendencies we might be able to stop uncomfortable symptoms, prevent obesity and fight disease.

How Can Nutrigenomics Help You Find The "Perfect" Diet?

There are two approaches to nutrigenomic testing:

Firstly, scientists can investigate how common variations found throughout the human genome explain individual differences in response to dietary intake.

These days we can easily access our own nutrigenomic data, which allows us to find our "perfect" diet, based on our unique genetic profile.

Many people thrive on a high fat ketogenic diet and have no problem with their cholesterol levels, while others experience the exact opposite response.

A simple DNA test can now help people determine if your diet of choice is actually the best option for you.

The second approach that nutrigenomics researchers use is to investigate how nutrients and bioactive components in food turn on or off certain genes that control important metabolic and physiologic processes in the body.

For example, researchers have identified compounds found in broccoli that can switch on a specific gene that helps the body detoxify harmful chemicals we are exposed to.

This "broccoli" gene is missing in about 20% of the population which means a large number of us will not benefit from the detoxifying properties of broccoli.

As you can see, a diet that is matched to your specific genotype is extremely powerful when compared to traditional diet formulations.

Nutrigenomic testing used to be reserved for the elite but is now affordable and easily accessible for everyone.

NutritionGenome have created a simple tool which allows anyone to gain an in-depth understanding of their potential genetic “weaknesses” and "strengths".

They have created an easy to use cheek swab for toddlers through seniors that will provide all the information you need on nutrition plus much more.

All you have to do is:

  1.  order your DNA test
  2.  Register your kit and take a swab
  3. Send it back.

DNA Test For Digestion

Nutrition DNA Test Results For Digestion: 

The NutritionGenome DNA Test Kit allows you to learn your body’s metabolism for protein, fat, carbohydrates, and higher needs for vitamins, minerals and compounds to discover your optimal ancestral diet.

Example Report Findings - Strengths Identified:

  • You have a good conversion of plant-based omega-3 ALA (walnuts, flax seeds, pumpkin seeds) to EPA and DHA.
  • Improved transportation of folate into the cell for the SLC19A1 gene.
  • Vitamin D levels more likely to be in range due to normal variant of CYP2R1 gene.
  • Normal adiponectin levels, linked to improved bodyweight, insulin and glucose levels.
  • Lower risk of iron overload for the HFE genes.
  • Improved glucose metabolism from saturated fat intake
  • Reduced likelihood of saturated fats causing weight gain for the APOA2 gene.
  • You have an increased ability to breakdown lactose in milk. Lower probability of chronically elevated uric acid levels.

Example Report Findings - Weaknesses Identified:

  • You have a reduced conversion rate of plant-based beta carotene (squash, sweet potatoes, carrots) to vitamin A. This increases your need for foods higher in vitamin A like eggs, cod liver oil, wild salmon oil and organ meats for skin, digestion,healthy eyes, lungs, and immunity.
  • Lower bifidobacteria levels in the gut that may decrease B12 absorption and GABA production due to variants in the FUT2 genes. This increases your need for prebiotic foods to help probiotic colonization like garlic, onions, leeks, pistachios, asparagus, bananas, kiwi and artichokes.
  • You are more likely to have low B6 levels due to variants in the NBPF3 gene, increasing the sensitivity to medications that deplete B6 (oral contraceptives, antibiotics, ACE inhibitors, antacids, proton pump inhibitors and more). You need to focus on increasing foods high in B6 like wild salmon, pistachios, avocados and potatoes.
  • Increased probability of elevated blood sugar from refined sugar and grains due to variants in TCF7L2. You may do better on a diet low in grains, higher in omega-3 fatty acids, diversified prebiotic foods, higher in olive oil, and includes cinnamon, turmeric and cordyceps mushrooms.
  • Potentially elevated levels of histamines in the digestive tract due to variants in APB1 gene that encodes for the DAO
    enzyme. You may be more sensitive to gut dysbiosis and fluctuating estrogen levels (females). Histamine is lowered by Vitamin C, choline, folate, magnesium, chamomile, basil, stinging nettle, echinacea, fennel, ginger and wild oregano.
  • Potentially elevated levels of histamine in the central nervous system, skin and bronchial tissue due to a heterozygous or homozygous HMNT gene.
  • You may be more sensitive to gut dysbiosis and fluctuating estrogen levels (females). Histamine is lowered by Vitamin C, choline, folate, magnesium, chamomile, basil, stinging nettle, echinacea, fennel, ginger and wild oregan

Nutrition DNA Test Results For Mood and Neurological: 

Determine serotonin, dopamine, adrenaline, GABA and glutamate gene function to understand your mental and neurological health.

Example Report Findings - Strengths Identified:

  • You have improved PEMT function for phosphatidycholine levels for a healthy liver, memory, homocysteine levels and REM sleep.
  • Normal levels of BDNF for improved glutamate modulation, brain repair, spatial learning, memory, and adaptability.
  • You do not have the APOE E4/E4 genotype, improving cholesterol transport and the maintenance of brain neurons.

Example Report Findings - Weaknesses Identified:

  • You have potentially lower levels of dopamine due to a lower density of dopamine receptors. This could theoretically create a higher likelihood of addictive behaviors, compulsive eating and ADHD. Keeping your blood sugar balanced with adequate protein and fiber, high intensity exercise, lower media exposure, vitamin D, omega-3’s and meditation all increase dopamine receptor density.
  • You have a slower breakdown of dopamine, adrenaline and estrogen, creating higher circulating levels in response to
    stress due to variants in the COMT genes.
  • You have a reduced glutamate to GABA conversion due to numerous variants in the GAD1 genes. If neurodegenerative
    disorders run in your family, all the genes associated with glutamate levels should be assessed.
  • You may have a delayed recovery from head injuries due to variants in SLC17A7. It is advised to be proactive with zinc,
    omega-3 fatty acids, Lion’s mane mushroom, magnesium and consistent exercise in case a head injury occurs.
