My guest on today’s podcast, Jonathan Clinthorne, PhD, has an intimate knowledge regarding the role that diet plays in immune function. Although it flies under the radar in nutrition science, the idea that certain nutrients can interact with the function of a type of cell known as a natural killer (NK) cell is very unique, an enchanting concept and certainly cutting edge, especially when you consider the role of mTOR activators such as leucine, and mTOR suppressors such as calorie restriction and intermittent fasting on NK cell maturation and function.

Dr. Clinthorne is an ultra-endurance athlete who was awarded his PhD in Human Nutrition from Michigan State University. He has served on numerous medical advisory boards and has been an author or coauthor on a number of research papers covering topics such as aging, caloric restriction, omega-3 fatty acids, probiotics, immune function, inflammation and human nutrition. When not working as the Manager of Scientific Affairs and Nutrition Education at Natural Grocers, you can find Jonathan running, climbing or skiing in the mountains of Colorado.
