Perhaps you, or someone you know on Facebook, has seen the new documentary, What The Health ? The film is encouraging veganism in viewers (there's even a meal planner to help you on your "plant-based journey"), based on a bundle of alarmist assertions and assumptions about the food industry. "Absolutely everyone is talking about [the movie], and I have clients and people calling me saying, 'I want to be vegan!'" says Mascha Davis , MPH, RDN, a registered dietitian nutritionist in Los Angeles and spokesperson for the American Academy of Nutrition and Dietetics. Veganism isn't new, but this movie is attracting a new crowd to the idea.
