are vegetarians nutrient starved – vitamin B12 (part 5 of 5)
Monday, January 11th, 2010B12 is the only vitamin that is not recognised as being reliably supplied from a varied wholefood, plant-based diet with plenty of fruit and vegetables, together with exposure to sun. B12 is produced by “good” bacteria which are found in the soil and on plants. Every herbivore in nature gets its supply of B12 from consuming these bacteria on the plants they eat. These bacteria then make homes in the gut of the herbivores that eat them. Carnivores get their B12 by consuming the organs and thus the bacteria from their herbivore prey.
Vitamin B12 is needed for cell division and blood formation. Neither plants nor animals make vitamin B12. Bacteria are responsible for producing vitamin B12. Although recommendations for vitamin B12 are very small, a vitamin B12 deficiency is a very serious problem leading ultimately to anemia and irreversible nerve damage.
