What is nutrigenomics?
Nutrigenomics is a rapidly advancing science that looks at the links between nutrition (the foods and nutrients needed to be healthy) and genomics (how the DNA encoded in your genes acts in your body). It’s a form of personalized nutrition that looks at how your personal set of genes influence the nutrients you need. Nutrigenomics is a very high-tech way of tailoring nutrition recommendations to one single person, based on their unique set of genes.
Here’s how your genes work. You have a set of genes that you inherited from your parents (half from each parent). This is your unique “genetic code.” Siblings (except for identical twins) from the same parents have some similarities, but each are still genetically unique individuals. You may have different hair or eye colors, or be a different height from your siblings. All of these uniquenesses are due to your genes.
Each gene is a piece of DNA that codes for one single protein. That’s why you have thousands of genes—because your body needs thousands of proteins to do all of its cellular and molecular jobs to keep you alive and healthy. There are several variations for each gene. For example, you may be genetically predisposed to having high (or low) levels of cholesterol or a resistance (or easier ability) to losing weight. Perhaps you have a lower (or higher) ability to use folate (vitamin B9), but maybe you are (or aren’t) very sensitive to caffeine or high levels of sodium. And possibly, you are very unlikely (or likely) to develop celiac disease.
How would you know? By having an accurate genetic test done to look for variations in all of those (and more) genes.
But, it doesn’t stop there. Your genes code for so many areas of health, like metabolism, inflammation, hormones, stress response, moods, detoxification, weight, fitness, cognition, and your ability to use essential nutrients from foods and supplements.
Imagine how you could tailor your food and lifestyle choices if you knew the areas that you as a unique individual should focus on, and which areas you need not worry too much about.
How can nutrigenomics help improve my health?
Let’s go through these examples so you can see what you can do when you learn your unique gene profile and take advantage of precision nutrition.
Susceptible to high levels of cholesterol
High levels of cholesterol can increase your risk for heart disease and stroke. This is partly the result of how your genes allow your body to process fats. If you knew you had genetic variants that made you prone to high levels of cholesterol, you could focus your foods on choosing more plant-based meals, heart-healthy fats, and higher-fiber foods.
Resistance to losing weight
Imagine knowing if your genes are influencing your ability to lose weight. If this were the case, you can be more forgiving in your weight-loss goals, and incorporate some cognitive behavioral therapy or mindfulness to help you.
Lower ability to use folate (vitamin B9)
Folate is found in green leafy vegetables and beans. Supplementation is often recommended for people who are or can become pregnant. If your genes code for a lower ability to use folate, then you may need to eat more folate-rich foods or take a supplement to ensure you get enough folate to compensate for your lower ability to use it so that you could maintain good health.
Not very sensitive to caffeine
Some people are able to metabolize (process and eliminate) caffeine faster than others. If you know that you are a “fast caffeine metabolizer,” you may be able to enjoy caffeine without having to worry too much about some of the common side effects that happen more often in people who are “slow caffeine metabolizers.”
Not very sensitive to high levels of sodium
Salt contains sodium, and too much sodium can increase blood pressure. However, some people are more sensitive to sodium than others.
Very unlikely to develop celiac disease
If you don’t experience gut symptoms and you are not likely to develop celiac disease, then you may not need to avoid eating gluten (a protein commonly found in wheat, rye, and barley).
And remember, these are just a few examples of how the variations in your genetic blueprint can impact your health and wellness, and how you can [strategically/proactively] address them to reach your health goals.
Nutrigenomic testing is very accessible now. It’s never been easier to answer the question, “Based on my genes, what should I eat to optimize my health?”
Why you should start now…
Science is quickly unravelling the mysteries of the human genome and that is a great opportunity for you to reach your optimal health with a strategy developed based on your genes. There is a genetic test that looks at dozens of health-related genes to identify the areas you will be naturally healthier in, and which areas may need some extra attention. Unique to you.
Wondering why some of your health efforts are so hard, while others seem easier? Want to know which foods, nutrients, or lifestyle choices will make the most difference in your life? Need a personalized nutrition plan based on your genes so that you can be confident it will be worth the effort?
