This dangerous cult excludes all animal products and is linked to extremist thinking, malnutrition, and early death. Because animal foods are the most nutritious and bioavailable, vegans are restricting themselves to the most nutrient poor foods available - however, they can still overindulge in unhealthy vegan junk food such as Oreos and Coca Cola. The Vegan Diet can cover many subtypes, which often object to other subtypes, and mostly represents the religious views of the dieters instead of the foods eaten.
