Chris and Xand continue their conversation with Professor Stella Volpe, head of the department of Human Nutrition, Foods, and Exercise at Virginia Polytechnic Institute and State University in the United States.

They talk to Stella about her work as a sports nutritionist, specialising in diabetes and obesity, about whether athletes need to think about magnesium differently, and the relationship between magnesium and diabetes.
