Moderation in all things is wise.

Agreed, Dr. Bill. I have talked to vegetarians about dietary deficiencies and they tell me that there is nothing available in meat which isn't available in some veggie or vitamin supplement. However, they acknowledge that they have to follow research on the subject more closely than people who eat meat.

Are they correct, Dr. Bill, or are they just fooling themselves? Is it possible to fulfill all dietary requirements without eating any meat?
