As a registered dietitian, I advocate all the time for people to eat sensibly and include lots of variety to mitigate disease risk and nutritional deficiencies. However, this generalized way of approaching health oftentimes isn’t enough, and may be due, in part, to individual genetic variances. How our genes determine our response to nutrients in food and beverages is known as the study of Nutrigenetics. Let’s take Vitamin A as an example:
People who have the GG variant of the BCMO1 gene are inefficient at converting beta-carotene to the active form of vitamin A. These individuals are considered low responders to dietary beta-carotene so
consuming enough active vitamin A can help support vision, immunity and reproductive functions.
