In terms of nutrition, you must ensure you obtain enough essential vitamins and minerals. Things that vegans generally need to make sure they are getting enough of are protein, iron, and vitamin B12 as these are normally found primarily in meat and dairy. However, if you learn to include vegan foods rich in such nutrients as regular parts of your diet, you can guarantee you won't be lacking. Such nutrient rich foods include fortified soy milk (which is also an excellent source of calcium), nuts, beans and legumes, and of course, vegetables.
