Health Implications of a Vegan Diet


To find scientific evidence supporting the theory that adherence to a vegan diet has significant health benefits. Specifically note any benefits associated with switching from a vegetarian to a vegan diet. Information should come from reputable organizations, peer-reviewed journals, and other credible sources.
