The case for a balanced plant-based diet has been exhaustively argued by many qualified nutritionists and other professionals, and is widely supported as perfectly healthy for all people, at all stages of life, by mainstream medical and dietary organisations, including the World Health Organisation, The American Dietetic Association and countless others.
Given these prominent endorsements, it is fair to argue that the burden of proof has in fact shifted to those who would continue to claim that a balanced vegan diet is in any way inferior or unhealthy, especially given the numerous studies indicating its strong correlation with low incidences of many dread illnesses.
Note: This article is still in development; we hope to offer a fuller account of the health reasons for going vegan in the near future. In the meantime, have a look at the excellent www.veganhealth.org.
