hmm, pity thing is that: "There are no reliable, unfortified plant sources of vitamin B12 (see B12 in Tempeh, Seaweeds, Organic Produce, and Other Plant Foods for more information); therefore fortified foods and/or supplements are necessary for the optimal health of vegans and even vegetarians in many cases. Luckily, vitamin B12 is made by bacterial fermentation such that no animal foods are necessary to provide it." http://www.veganhealth.org/articles/vitaminb12 problem is, that these doesnt come naturaly in to a vegan food. it must be fortified. well i once read it may appear in food through the natural way. but it can only apear in "soiled" vegetabels. so in India for example, many people live a vegan lifestlye but they barely dont get any b12 lacks, because they eat rather "soiled" vegetables. and how the research says b12 appears on "soiled" plants. they get the b12, because they dont wash the plants that clean. well, thats a good point, they can do it this way, because they dont use on this vegetables that much pesticides (well i read it that way in an article, but i'm still not sure if they dont use that much pesticides). and the next point is: many indians which emigrated to the western countries, showed a lack of b12 after some time. so i mean we cant eat our vegetables without washing them, after we know how they're threatened with pesticides and insecticides (well they're allready sold washed). that means we barely cant enough b12 the natural way, with a vegan diet nowadays.(its what research says). In the past it was surely possible for the ppl. to get enough b12 "the natural way" But when i'm thinking about it, the b12 fortified food isnt that bad, (somehow natural too, besides that, meat isnt that natural too nowadays(and milkshit etc..)) hmm, i read somewhere that a little amount of barm could provide you the rda of b12 too, but i have to analyse that. with regards ppl.
