Vitamin B12 deficiency is related to megaloblastic anemia that results in cognitive dysfunction, and it increases the risk for arterial vascular disease and thrombosis. Obviously a diet based primarily on grains will be deficient in vitamin B12, including strict vegetarian diets. We were not evolved to eat plants exclusively.
