How does your DNA test affect your dietary choices? Our Holistic Nutritionist explains how to tailor your diet around your DNA results.

by Jen Casey, CNP

This is not your ancestry DNA test, although those are super cool.

This new, diet-focused DNA test is a new tool that our Holistic Nutritionist uses to learn how your body metabolizes macronutrients, naturally. Over 100 of your key genes that are responsible for metabolic processes within your body are tested.

How can a DNA test express this kind of information? Nutrigenomics is the study of the interaction of nutrition and genes. A diet-focused DNA test shows how diet, exercise and environmental factors are related to how your genes are expressed and what outcomes you are predisposed to. Some nutrients can turn your genes on and off! How cool is that?







The test results give you some insight into scenarios like:

  • why you aren’t metabolizing fats efficiently
  • why you might have an increased need for vitamins D, C, A or B
  • why you prefer and function well on a high protein diet
  • your tolerance for caffeine, lactose, gluten and alcohol
  • why your best friend can eat anything she wants and never gains weight…but your jeans don’t fit the moment you indulge

How does it work?

Here is what the whole process looks like: Book in for a quick 15 minute appointment at the clinic to pick up your DNA test and schedule in your follow-up hour (aprox 3-4 weeks later). A non-invasive saliva sample is taken and sent in to the lab. The 50pg results, showing variances in the genes responsible for over 100 markers, are sent via email to you and our Nutritionist.

For example:

Your report shows that you have a 67% variance in the key genes responsible for calcium (Ca) absorption. This means that you are at an increased risk for developing problems associated with Ca absorption, such as osteoporosis, or blood pressure issues. Why? Calcium is the most abundant mineral in the body, and it is required for muscle function (including your heart. It is a big muscle!), blood pressure regulation, healthy bones and teeth, and even hormone regulation.

Your genes will not change, but you can be proactive with what and how you eat. When your test results are in, your appointment with our Holistic Nutritionist includes specific dietary recommendations to help you optimize your calcium absorption and reduce your risk of future health problems related to the variance in your genes.

Suggestions such as:

  • weight-bearing exercises to increase bone density
  • increase dietary sources of calcium, such as salmon, spinach, kale, parsley, sunflower and chia seeds, cheese and organic milk
  • foods to avoid that interfere with calcium absorption

What else does the test cover?

Other areas tested are:

    • Diet Management: How your body burns fat, your sensitivity to carbohydrates and insulin, your cholesterol regulation, and your protein requirements to help determine your optimum diet
    • Weight Response: Your body’s ability to control body mass index (BMI)
    • Food Tolerances: Your tolerances to alcohol, caffeine, salt, lactose, gluten and sugar cravings
    • Food Taste and Preferences: Your preference for caffeine, carbohydrates, fats and protein. Your taste ability for bitter, salt, sweet tastes, as well as smoking behaviour
    • Vitamins and Supplements: Your need for vitamins including vitamin A, vitamin B6, vitamin B9 (folate), vitamin B12, vitamin C, vitamin D, vitamin E as well as your need for supplements such as Calcium, Iodine, Iron, Omega 3 and Omega 6 to stay healthy

What doesn’t the test cover?

This particular diet-focused test does not cover areas such as allergies, ancestry, inherited diseases, or illnesses.

How often do I need to do this test?

This is a one-time test. Your genes won’t change, but you will have the tools to optimize your health and the function of your genes through diet. Book in at Rocky Point Wellness Clinic to pick up your test and schedule your 1 hour test result appointment.
