Both sets of my grand-parents became vegetarian (my grand-father was also a doctor in Loma Linda that lived to be 92). Both of my parents were raised vegetarian and so were their children. I became mostly vegan 24 years ago, and fully vegan about 5 months ago, after viewing videos on what is being done to animals to obtain milk and eggs. I couldn't be a part of it. Being vegan is a good, healthy choice. I do take vitamin supplements, which is a good idea for most people...no matter their diet. We need to care about a good diet from babyhood...as we lay the foundation for future health from the start. I like this video and love that Dr. Wareham is doing so well as a vegan. It's an inspiration!
