About this episode
This episode discusses the concept of the food matrix and its implications for nutrition, featuring insights from registered dietitian Sally Cummins.
Food is more than the sum of its parts. Nutrients in supplements act differently than the same nutrients in whole foods. The way those nutrients are packaged, bonded and processed all factor into what’s known as a food matrix. On this episode of On Nutrition, we talk with Sally Cummins, a registered dietitian and senior vice president of nutrition affairs at the National Dairy Council. She shares the science behind the dairy food matrix and explains how you can see the food matrix at work in everyday foods. Sign up to receive Mayo Clinic Press emails.
