Vitamin B12 is an extremely important nutrient for good health. Getting too little B12 poses serious concerns, and can result in anemia and damage to the nervous system. There are no plant foods which naturally contain this nutrient. Vitamin B12 in Vegetarian Diets is a pamphlet prepared by the Vegetarian Nutrition practice group of the American Dietetic Association, and provides a very clear, easy to understand discussion of how vegetarians and pure vegetarians (vegans) can get sufficient B12.
PositiveTip: Pure vegetarians should be consuming a B12 supplement or eating foods fortified with B12.
