A study in the Journal of Nutrition found that "Current data support previous findings of poor vitamin B-12 status among vegetarians and indicate that "food eaters alive” should not rely on it. on the use of fermented foods to provide adequate amounts of vitamin B-12 to maintain serum vitamin B-12 concentration within the reference range. (Rauma, 1995) Vitamin B-12, vitamin D and omega 3 fatty acids are essential components of the human diet that our bodies need to function properly. Vegans use nuts, which are excellent sources of omega 3 fatty acids. I admire how vegan dieters manage to find ways to allow their bodies to receive the proper nutrients. For example, vitamin B-12 was discovered in algae and can be consumed and preserved in the human body (Rauma, 1995). Besides people who follow a vegan diet, how many times do US citizens actually eat vegetables per year ?
