There is a wonderful answer in this URL: http://wiki.answers.com/Q/Is_there_Vitamin_B12_in_fruit_or_vegetables Quote: "Vitamin B12 -- The Jury Is Still Out There is no Vitamin B12 in fruits or vegetables. There is controversy over this, of course. Many people say that the only foods which contain Vitamin B12 are animal-derived foods. This also is untrue. No foods naturally contain Vitamin B12 -- neither animal or plant foods. Vitamin B12 is a microbe -- a bacteria -- which is produced by microorganisms. Vitamin B12 is the only vitamin that contains a trace element -- cobalt -- which give this vitamin its chemical name, cobalamin, which is at the center of its molecular structure. Humans and all vertebrates require cobalt, although it is assimilated only in the form of Vitamin B12. If you want to take Vitamin B12, be sure you know how much you need for your body size and don't overdose on it. Get more information from a homeopath or from your medical doctor. Fruits and vegetables do not contain Vitamin B12. Strangely enough, though, if you are in the habit of eating unwashed veggies, these may contain small amounts of B12, as it is produced by microbes found in soil. However, it is possible to get Vitamin B12 from vegetarian sources, such as yeast and seaweed. It was thought that these foods contain a type of B12 that cannot be absorbed by the human body. However, new research indicates that humans can, in fact, absorb the types of cobalamin found in these foods. Recent research has also found out that the absorption of B12 from dairy and meat is much poorer than it was thought to be. As a result, a large part of the population is suffering from a B12 deficiency, even though they include plenty of animal-based foods in their diet. Since most of us don't eat a perfect diet, we miss out on some important vitamins and minerals. Having just become a vegan after being a vegetarian for many years, I was concerned about the B12 issue. There are many sublingual supplements on the market you can take to ensure you are getting enough B12. I suggest sublingual, as the body does not absorb it well enough via the stomach and liver. With sublingual, it goes right into the bloodstream. No, the best source for Vitamin B12 is liver. It can also be found in soymilk, soybeans, eggs, clams, salmon, crab, milk, dairy products, and more."
Vitamin B12 is water soluble.
Perncious anemia is caused by the body's inability to absorb the vitamin B12 from the gastrointestinal tract, due to a loss of gastric parietal cells. Regular B12 supplementation can keep pernicious anemia at bay, though it is not a complete cure. B12 is a vitamin obtained from meat and dairy products.
