Myth #22: “But I need to eat meat for my blood type.”
This theory, primarily made famous by the best-selling book “Eat Right 4 Your Type”, claims that humans must match their diets with their blood types in order to maintain optimum health — and more specifically, that those individuals having type-O blood need to eat animal flesh in order to do so. Not only have I personally debunked this theory (I am blood-type O-negative, have been vegan for almost two years now, and have never been healthier or felt better in my life), but nutritionists see little scientific merit in it as well. Even the author of the book himself notes that “type-O people” might want to “explore a more high-protein lifestyle” — not that they must obtain that protein from animals.
Current status of this Myth: Debunked
Justification it provides for eating animals: NONE
