Nutrigenetics

Why do some thrive on a high saturated fat diets and others develop heart disease? How can one population eat a high carbohydrate diet, while another group eating the same diet develops type 2 diabetes at an accelerated rate? The emerging science of nutrigenetics offers answers. Nutrigenetics, which involves tailoring diet to DNA, helps sheds light on how genetic variability plays a big role in why people respond differently to different diets. The articles published here cover the latest developments, including ApoE4 and brain health, B vitamin and fatty acid metabolism, the latest science on popular SNPs, such as CBS, COMT and MTHFR, and much more. For more information on the genes we report on in our custom nutrition plans, take a look at our Guide to Nutrigenetics.
