Vitamin B12 breakthrough for more complete Vegetarian and Vegan diets

Scientists have made a significant discovery about how the vitamin content of some plants can be improved to make vegetarian and vegan diets more complete. Vitamin B12 (cobalamin) is an essential dietary component but vegetarians are more prone to B12 deficiency as plants neither make nor require this nutrient. But now a team, led by Professor Martin Warren, has proved that common garden cress can take up cobalamin.
