<< nnot absorb or reabsorb B12 become deficient in only 3 or so years. "Careful studies from England on several hundered vegans showed that they all eventually get vitamin B-12 deficiency disease...". The reference is Chanarin et al; Megaloblastic anemia in a vegetarian Indian community. >> confirms my point, Indian Vegetarians are not Vegans, they are lacto vegetarians, and as such drink and use milk, which in England has antibiotics in it which inhibits the production of B12 in the colon, the same would apply to most Iranian vegetarians. All vegans are vegetarians, but not all vegetarians are vegan, only about 1/3 and most of us westerners Thanks, jerry
