The future of nutrition advice.
How is precision nutrition different from current nutrition advice?
Dr. Frank Hu: The idea of precision nutrition is to have the right food, at the right amount, for the right person. Instead of providing general dietary recommendations for everyone, this precision approach tailors nutrition recommendations to individual characteristics, including one’s genetic background, microbiome, social and environmental factors, and more. This can help achieve better health outcomes.
Not everyone responds to the same diet in the same way. For example, given the same weight-loss diet, some people can lose a lot of weight; other people may gain weight. A recentstudy in JAMA randomized a few hundred overweight individuals to a healthy low-carb or low-fat diet. After one year, there was almost an identical amount of weight loss for the two groups, but there was a huge variation between individuals within each group — some lost 20 pounds. Others gained 10 pounds.
