With each passing month, more research is being published and our understanding of effective means for personalizing diets grows. Last month a study was published in the journal Cell entitled “Personalized Nutrition by Prediction of Glycemic Responses.” Since then it has been making big waves in the media being touted by some as the diet study that changes everything we know about dieting. While this hyperbolic statement is grossly misleading, the study itself is very interesting, reinforcing things that we already knew about individual diet response and while also shedding light on some new areas.
