The gut is a profoundly important (yet often underappreciated) organ that needs to function well for athletes to optimize training, performance, and recovery.

Patrick Wilson, PhD, is one of the world’s foremost experts on the connections between exercise, nutrition, and the gut and is the author of the recently released book, The Athlete’s Gut: The Inside Science of Digestion, Nutrition, and Stomach Distress.

In this series of articles, Patrick will shed light on the inner workings of the gut, why certain athletes are prone to digestive issues, and how they can go about tackling these gut issues using nutrition, training and psychological strategies.
