The new Netflix documentary “What the Health” is made by two animal rights activists who argue that a vegan diet is the cure for all chronic diseases; that meat, dairy and fat cause those diseases; and nonprofits like the American Heart Association don’t want you to know the truth. Some of the claims in the film: One egg is as dangerous as five cigarettes, and eating processed meat is as bad as smoking. Some nutrition experts say this film is hyperbolic and not scientific.
