Explanation:
Thanksgiving arrives every year with a heated debate over how to best cook that plump and juicy turkey. But the idea of a tofu turkey (also known as a “tofurkey”) has gone from a joke a couple years ago to a reality for many. While vegetarianism has been practiced for over a thousand years in some countries, it is a relatively new concept in the West. And so, with the question cropping up more and more often, should we eat meat?

As yet unanswered
Can consensus of opinion be trusted?
Alex said, "Prof Francione's cogent argument turns on the assumption that consuming flesh is not necessary. This assumption is sound given that even conservative dietitians argue that one can live an optimally healthy life free of meat and the reproductive excretes of nonhuman animals."
It may be possible for some people to live an optimally healthy life free of meat and dairy. However, variations in biochemical and physiological makeup indicate that many shouldn't attempt to nourish themselves on a diet that totally excludes animal products.
I know at least a half dozen people who experimented with the vegetarian approach but had to give it up because it damaged their health. One man showed me huge red blotches on his back that resulted from his experiment. Another told me he was cold all the time. Another, now in her mid twenties, recently added meat to a diet that already contained eggs.
As far as dietitians are concerned, their education is shaped by the food manufacturing industry which employs about half of them. Food manufacturing involves mostly, wheat, corn, soybeans, and sugar. One estimate is that Americans obtain about 70% of their caloric intake from these four food crops.
Corporate influence is also apparent in the recommendation to restrict saturated fat intake as much as possible. There is no solid experimental evidence suggesting saturated fats from animal products or other sources pose a health hazard. Quite the contrary. Recent research by Jeff Volek and others indicates that replacing vegetable oils with butter, lard, and beef tallow improves triglyceride and cholesterol blood values. Research into the effects of high sugar (especially fructose) intake by Peter Havel indicates that it is fructose, not saturated fat, that contributes the artery-clogging effect so prevalent in developed countries.
Several times a year I have conversations with people who are dumbfounded that their grandparents lived long and were healthy and active to the end on a supposedly unhealthy diet that included copious amounts of bacon, eggs, and butter. And I recently clipped an article from our local paper about a 106 year old woman. I quote the last two sentences: As she fished from the dock, slowly retrieving a lure and hoping for a strike, she passed along her secret for a long life. "I eat bacon every morning," she said, "Crisp bacon."

regarding nutrition
You said, "many shouldn't attempt to nourish themselves on a diet that totally excludes animal products."
Unless someone does not have access to a wide variety of plant foods or that person refuses to eat a wide variety or can't eat a wide variety due to allergies, there is no reason anyone can't go vegan and enjoy optimal health.
Any diet can lack nutrients. Whether you eat meat or not, you need to pay attention to your diet and eat a wide variety of nutrient dense foods.
In my experience, the people who have "failed" vegetarianism or veganism simply refused to eat a wide variety of plant foods and instead starved themselves or their children by consuming a very low variety and low calorie diet. I have also heard of people who simply couldn't figure out ways to modify a vegan diet for specific food allergies. Luckily, some people have persevered and have successfully adapted veganism to their allergies and conditions. They are paving the way for more people to do the same.
This has more to do with our society's lack of nutritional understanding as well as the scientific community's preference for certain diets and certain nutritional studies than it has to with veganism.

Generalizing from personal experience problematic.
Hi Elaine,
You are absolutely correct to say that people need to consume nutrient dense foods. Wide variety, however, may not be a requirement for optimum health. It's been reported that raw milk from pastured livestock has furnished adequate nutrition for certain individuals for periods ranging up to four decades. Google "The Milk Book."
This is not to suggest that everyone is capable of metabolically processing such a boring diet. Variations in biochemical and physiological makeup make individualized nutrition a scientifically verifiable necessity.
At the extremes are the obligatory vegans and obligatory omnivores. Most of us fall in the middle range. It would be an interesting experiment to try to adapt a group of healthy omnivore athletes to a high quality vegan diet to see how it affects physical performance.
Responding to a comment of mine, Dr. Michael Eades said he finds that vegetarian athletes invariably improve when he has them add meat to their diets.
On the negative ledger for vegetarians, Dr. Michael Eades reports that "... vegetarians have significantly higher rates of advanced glycation end products (AGE) than do omnivores." To read more about this, Google "Eades Vegetarians Age Faster."

Cow's milk is not healthy for most people
Milk!?
The vast majority of humans cannot drink cow's milk without negative repercussions.
Cow's milk is for baby cows, not adult humans.

Milk still benefits some.
Elaine,
By your logic, since many people cannot tolerate peanuts, no one should consume peanut butter. Likewise, since seeds are meant for reproduction, people ought not to use them for food.
Realistically, nutrients are nutrients whatever their configuration. Where is the sense in restricting ones choices simply because not everyone can tolerate all the same foods?
Part of the problem regarding modern methods of milk production has to do with pasteurization. My son-in-law is allergic to pasteurized dairy products but can drink raw "milk without negative repercussions."

In reality...
You said, "nutrients are nutrients whatever their configuration."
Actually, that's not true. Nutrients interact with other nutrients and become more or less effective. Read The China Study by by Dr. T. Colin Campbell and Thomas M. Campbell II. Here's an excerpt: http://www.thechinastudy.com/PDFs/ChinaStudy_Excerpt.pdf

Kitava Study also interesting
Elaine, Thanks for the link to the China Study Introduction. I plan to read the book now because it gets mentioned frequently by those who advocate low-fat diets to prevent heart disease, obesity, and diabetes.
You are correct to say that "Nutrients interact with other nutrients and become more or less effective." However, to banish certain sources of nutrients from ones diet simply because they are derived from animals makes little sense in light of the fact that, in nature, animals consume whatever food is available and suitable.
Here in the Rocky Mountains of Montana the bears consume enormous amounts of huckleberries in late summer. It's said that the difference between good and poor huckleberry crops can translate into a variation in body fat (for a bear going into hibernation) of up to 200 pounds.
At some high elevations bears also feast on enormous numbers of moths to gain weight. Along the Pacific coast the bears consume salmon. So what's the appropriate diet for a bear? Are huckleberries superior to salmon or vice versa? They both seem to be suitable because bears are omnivores.
From an evolutionary perspective, to suggest, that humans ought to be vegans ignores the fact that our closest primate relative, the chimpanzee, consumes meat. http://www.youtube.com/watch?v=KTPkmH4hWCs
As far as health is concerned, it's the modern diet with its emphasis on grains, sugars, and vegetable oils that is killing us early. Suggest you check out the Kitava Study at http://www.staffanlindeberg.com/TheKitavaStudy.html and also read these comments about it here: http://high-fat-nutrition.blogspot.com/2007/06/living-on-isolated-island-of-kitava.html

Not true
Sure there are plenty of people who are lactose intolerant. But the "vast majority"? That is not true, and I think you know it.

Athletes improve when you give them steroids, too. Doesn't make it a good idea.

Good point
Yea, let's compare eating meat , which is done by approximately half of the animal kingdom (totally random, made up statistic, but you get the point) to illegal drug use . I can see Goodwin's law coming true any minute now!
