Can Athletes Perform Well on a Vegan Diet?
With the publication this month of “Eat and Run: My Unlikely Journey to Ultramarathon Greatness,” by the vegan distance runner Scott Jurek, vegan diets have become a wildly popular topic on running-related Web sites. But is going totally meatless and, as in Mr. Jurek’s case, dairy-free advisable for other serious athletes, or for the rest of us who just want to be healthy and fit?
To find out, I talked with three experts about why, and whether, those of us who are active should consider giving up meat or more. None of the experts are themselves vegan, though two are vegetarian: David C. Nieman, a professor of health and exercise science at Appalachian State University, who’s run 58 marathons or ultramarathons and has studied runners at extreme events; and D. Enette Larson-Meyer, an associate professor of human nutrition at the University of Wyoming, as well as a longtime competitive athlete and author of “Vegetarian Sports Nutrition.” A third expert, Nancy Clark, who describes herself as “two-thirds vegetarian” — she doesn’t have meat at breakfast or lunch, but does at dinner — is a sports nutrition expert in Massachusetts and the author of “Nancy Clark’s Food Guide for Marathoners.
