article on Vegetarianism and how it is not as healthy as its proponents tout:
The Myths of Vegetarianism
by Stephen Byrnes, ND, PhD, RNCP
"An unflinching determination to take the whole evidence into account is the only method of preservation against the fluctuating extremes of fashionable opinion" -- Alfred North Whitehead
Dr. Byrnes sets the article up with the telling of a consultation he had with a vegetarian patient. He then goes on to list 15 myths about Vegetarianism that are worth looking at. He also provides several references (text only, not links) for each Myth so you can do your own research.
Here is a partial excerpt of the first two. Well written and researched:
MYTH #1:
Meat consumption contributes to famine and depletes the Earth's natural resources.
Some have argued that cows and sheep require pasturage that could be better used to raise grains to feed starving millions in Third World countries. Additionally, claims are made that raising livestock requires more water than raising plant foods. Both arguments are illogical and simplistic.
The pasturage argument ignores the fact that a large portion of our Earth's dry land is unsuited to cultivation. The open range and desert and mountainous areas yield their fruits to grazing animals (1).
Unfortunately, the bulk of commercial livestock are not range fed, but stall fed. They do not ingest grasses and shrubs (like they should), but are fed an unnatural array of grains and soybeans. It is true that these foods could be fed to humans. The argument here, then, is not that eating meat depletes the Earth's resources, but that commercial farming methods do. Such methods also subject livestock to deplorable living conditions where infections, antibiotics, steroids and synthetic hormones are common. These all lead to an unhealthy animal and, by extension, an unhealthy food product. Organically raised livestock, then, is a healthier and more humane choice (see myth #15 for more on this topic).
As for the claims that raising livestock requires more water than raising plant foods, water that livestock drink would be drunk by them anyway, even if they were not being raised for food. Additionally, the urine of grazing animals, which mostly comprises water, is rich in nitrogen which helps replenish the soil. Much of the water used in commercial livestock farming, however, is used up in growing the various grains and soybeans fed to the animals. If a concerted effort were made to return to the ecologically sound "mixed farm," (described below), then such huge expenditures of water would be unnecessary.
MYTH #2:Vitamin B12 can be obtained from plant sources.
Of all the myths, this is perhaps the most dangerous. Vegans who do not supplement their diet with vitamin B12 will eventually get anaemia (a fatal condition) as well as severe nervous and digestive system damage (6). Claims are made that B12 is present in certain algae, tempeh (a fermented soy product) and brewer's yeast. All of them are false.
Like the niacin in corn, the B12 analogues present in algae and tempeh are not bioavailable. We know this because studies done on people's blood levels of B12 remained the same after they ate spirulina and tempeh; there was no change, clearly indicating no absorption by the body (7). Further, the ingestion of too much soy increases the body's need for B12 (8). Brewer's yeast does not contain B12 naturally; it is always fortified from an outside source.
Some vegetarian authorities claim that B12 is produced by certain fermenting bacteria in the intestines. This may be true, but it is in a form unusable by the body. B12 requires intrinsic factor from the stomach for proper absorption in the ileum. Since the bacterial product does not have intrinsic factor bound to it, it cannot be absorbed (9).
It is true that vegans living in certain parts of India do not suffer from vitamin B12 deficiency. This has led some to conclude that plant foods do provide this vitamin. This conclusion, however, is erroneous as many small insects, their eggs, larvae and/or residue, are left on the plant foods these people consume, due to non-use of pesticides and inefficient cleaning methods. This is how these people obtain their vitamin B12. This contention is borne out by the fact that when Indian Hindus migrated to England, they came down with pernicious anaemia within a few years. In England, the food supply is cleaner, and insect residues are completely removed from plant foods (10).
Interesting -- I was a Vegetarian for a few years about ten years ago. I felt better at first but caught every cold that came around and had lower energy than normal. I was careful with my diet too and took vitamin supplements including B12. That first bite of roast beef was incredible -- my body was craving it and I was blind to its needs. Now, I am in better shape than ever.
I am not advocating a diet of raw meat and nothing else; Jen and I consume a lot of vegetables and grains but meat is a definite part of our diet.
