There is no vitamin or mineral needed by the human body which cannot be obtained through a vegetarian or vegan diet. Yes, it does require a lot of planning and knowledge... but then again, so does a meat-eater's diet! Most meat eaters are NOT getting well balanced diets, and it is not that much more difficult to have a good diet if you're vegetarian/vegan. I applaud Albasari for having the morals and the courage to refrain from eating meat. I only wish I and other people had what it took (the reasons why I don't/can't are complicated, but I do try to minimize my meat consumption).
