oing vegan is becoming more popular, with more supermarkets catering to customers who follow this diet, which relies exclusively on plant-based foods. Plant-based foods have moved further into mainstream markets, where sales rose to 20 percent over the past year, according to new retail data from Nielsen and the Plant Based Foods Association.
While there are many benefits to going vegan, including a better complexion and increased energy levels, those who follow a strict vegan diet are at risk of developing a deficiency in vitamin B12, which comes only from animal-based foods in its natural form.
Healthline explains that vitamin B12 is essential for producing "the DNA needed to make red blood cells". Lacking the vitamin causes incomplete cellular development building, and the resulting red blood cells lose their ability to divide. This is a type of anemia called megaloblastic anemia, a condition in which insufficient red blood cells are circulating through the body so the skin appears pale or yellowish.
Megaloblastic anemia can also cause weakness and fatigue, as there aren't enough enough red blood cells to carry a sufficient amount of oxygen throughout the body.

If low vitamin B12 levels are left untreated, the condition can result in nervous system damage with symptoms such as pins and needles, balance and coordination problems, breathlessness, dizziness and disturbed vision.
If you are following a strict vegan diet that contains no animal products or derivative foods, make sure that you are getting enough B12 through fortified foods like bread and plant-based milk, notes Healthline.
Shira Eytan, a board-certified endocrinologist, said to Health.com that those who follow a vegan diet are advised to consult a doctor or nutritionist to determine whether or not they should be taking vitamin supplements. (mut)
