According to the Academy of Nutrition and Dietics "vegetarian and vegan diets are appropriate for all stages of the life cycle [and] ... help reduce the risk for heart disease, high blood pressure, type 2 diabetes, stroke, obesity, and some types of cancer." One supplement that is recommended is vitamin B12. Carnists generally get this vitamin from animals who were injected with the vitamin supplement. That vegan and vegetarians must be concerned with protein adequacy is a myth as all plants contain complete proteins. As long as enough calories are consumed, protein needs are met.
