If you come across research on the net or elsewhere that tries to document information about plants, vegans and B12, please post the URL here with (at least) an excerpt of the text (unless it is copyrighted). I t doesn't matter what the conclusions are or if you agree in them, this thread is just meant to reflect the info that is available out there. Thanks!

Serum vitamin B12 levels in young vegans who eat brown rice.

A nutritional analysis was conducted on the dietary intake of a group of 6 vegan children aged 7 to 14 who had been living on a vegan diet including brown rice for from 4 to 10 years, and on that of an age-matched control group. In addition, their serum vitamin B12 levels and other data (red blood cell count, hematocrit, hemoglobin, etc.) were determined in the laboratory. In vegans' diets, 2-4 g of nori (dried laver), which contained B12, were consumed daily. Not a single case of symptoms due to B12 deficiency was found. There were no statistically significant differences between the two groups with respect to any of the examination data, including B12 levels (p < 0.05). Therefore, consumption of nori may keep vegans from suffering B12 deficiency.
