According to a study published in the New England Journal of Medicine, “Over the course of two months, a 62-year-old man developed numbness and a “pins and needles” sensation in his hands, had trouble walking, experienced severe joint pain, began turning yellow, and became progressively short of breath. The cause was lack of vitamin B12 in his bloodstream….
Vitamins are required in organisms in limited amounts; however, the problem with vitamins is that a human body cannot produce sufficient quantities of these compounds on its own. Therefore, they must be acquired through food. B12, in particular, is an important vitamin that supports several functions of the brain and nervous system in humans. It is also instrumental in metabolism, red blood cells formation and DNA synthesis.
1The Vegan Diet

Being vegan means to give up eating all the foods of animal origin. So, the list of foods that the rules of the vegan diet do not permit is as such:
- Meat and fish of any kind
- Poultry meat and eggs
- Dairy products and honey
Many people get into this diet for ethical reasons while others think of the advantages of it in weight loss. Mostly, the diet relies on grains, fruits and vegetables. While the eating regime can be extremely beneficial for the most part, it does not come without risks.
This lifestyle, though healthy and environmentally responsible, is not an ideal one. The vegan foods lack, rather have inadequate quantities of certain nutrients that are extremely necessary for good health.
