Although there are health advantages of being a vegetarian,
there are also disadvantages. Vegetarians can develop defficiency in vitamins B12, B2, and D. B12 is only present in animal products. Reduced levels of B12 can
cause anemia and degenerative changes in the central nervous system. Vegetarians must get
vitamin B12 from either a vitamin supplement or soy milk. Or they can just be sure to eat
broccoli, asparagus, and almonds.Calcium, iron, and zinc,
are all major minerals. It's difficult to get calcium without
consuming dairy products. Mustard greens, broccoli, and fortified tofu contain calcium but
substances in some vegetables, such as oxalic acid, usually decrease the absorption of
calcium.
There are nine essential amino acids that act as a
building block for protein. No single plant contains all these acids, except for soy
beans. It is important for a vegetarain to eat a wide variety of protein-rich foods, such
as nuts, legumes, and seeds, to avoid loss of these amino acids. |
