Recent Advances and Controversies in Genetic Testing for Precision Nutrition with Ahmed El-Sohemy, Ph.D

There is increasing awareness among researchers, educators, healthcare professionals and consumers that the one-size-fits-all, population-based approach to nutritional guidance is inefficient and sometimes ineffective. Genetic differences can explain why some people respond differently from others to the same foods, beverages and supplements they consume, and studies show that giving DNA-based dietary advice is superior to population-based recommendations for improving compliance. With increasing consumer awareness and demand for genetic testing, there is a need for nutrition professionals to have sufficient knowledge to understand the science behind these tests, and determine the benefits and limitations of both the science and the testing.
