I agree with shrumeo. we were made to eat meat, we have thrived on eating meat, why stop now? it is the niche that we are (meant to/ are) occupying right now.
on the other hand, i do enjoy playing the devil's adovacate so here it goes:
Since ppl complain that humans are to "animal-ish" in their behavoir, is this not some way to separate ourselves and say "Yo everyone look at me! I am above those puny animals for I have decided not to be like them!"? Also maybe this whole "man is meant to be a meat eater" thing is outdated? Yes eating meat has gotten us this far, but slaves made Rome great(for a while) yet most ppl would agree that slavery is a old fashion tradition that is evil. Is this not like slavery in a way?
Where do we draw the line? Don't plants have a right to live out their lives and reproduce too? I guess most fruit-bearing plants rely on being eaten to reproduce, but lettuce doesn't, neither does celery or a ton of plants we eat. Shouldn't we limit our diet to plants that bear fruit (beans and nuts too) and leave (no pun intended) the leafy plants, roots, and tubors alone to live out their lives fully?
One extreme is Soylent Green and the other extreme is starvation by altruism.

its true though. why don't we eat humans? we think of ourselves as a "civil" and "brilliant" species. therefore, why waste a perfectly good species right? if you look at it though, not many species actually eat their own...save for the insects and a few fish. animals don't really eat there own species either.
Exactly. But, we are not "above" animals since we are inevitably animals ourselves. We may not be able to escape the 'cycle of life' unless we come up with Star Trek like replicators or begin to design the evolution of our own species.

I'm sorry for being so blunt, shrumeo, but you have no idea of what you are talking about. Soy has all the essential amino acids, and other plants complement each other to get the right amino acids. Check our the American Dietetic Association's website:
http://www.eatright.org
All right. I was going on old info that claimed that soy did not provide all essential amino acids. Perhaps new research has shed light on this.
BUT, maybe we can't rely on soy for our "meat replacement."
Because it contains isoflavones.
Depending on who you ask, these are good for you and bad for you.
While they may be great for post-menopausal women, I don't think I want to start dosing myself with what could be called an "estrogen replacement."

http://www.fda.gov/fdac/features/2000/300_soy.html
"Soy by itself is not a magic food," says Christine Lewis, acting director of the Center for Food Safety and Applied Nutrition's Office of Nutritional Products, Labeling and Dietary Supplements. "But rather it is an example of the different kinds of foods that together in a complete diet can have a positive effect on health."
The problem, researchers say, is that isoflavones are phytoestrogens, a weak form of estrogen that could have a drug-like effect in the body. This may be pronounced in postmenopausal women, and some studies suggest that high isoflavone levels might increase the risk of cancer, particularly breast cancer. Research data, however, are far from conclusive, and some studies show just the opposite--that under some conditions, soy may help prevent breast cancer. It is this scientific conundrum, where evidence simultaneously points to benefits and possible risks, that is causing some researchers to urge caution.
Unlike the controversy surrounding soy isoflavones, available evidence on soy protein benefits is much clearer. That's why FDA limited its health claim to foods containing intact soy protein. The claim does not extend to isolated substances from soy protein such as the isoflavones genistein and daidzein.
---------------------------
Anyway, why is soy protein called a "meat replacement" if we don't normally rely on meat for complete nutrition? This is what we are naturally designed to do. If that ONE plant (soy) didn't exist, we'd be left with the multitude of animal-based options that we have had throughout our evolution to complete our dietary needs. Not all our ancestors had access to soy beans. If they did, we'd probably all be eating tofu for lunch every day and not hamburgers.

Ah!
here we go:

This position paper reviews the current scientific data related to key nutrients for vegetarians, including protein, iron, zinc, calcium, vitamin D, riboflavin, vitamin B-12, vitamin A, n-3 fatty acids, and iodine. A vegetarian, including vegan, diet can meet current recommendations for all of these nutrients. In some cases, use of fortified foods or supplements can be helpful in meeting recommendations for individual nutrients.
-------
So, if you are a vegan, you must SUPPLEMENT your diet with manufactured pills in order to meet recommended requirements.
-------
Vegetarian diets offer a number of advantages, including lower levels of saturated fat, cholesterol, and animal protein and higher levels of carbohydrates, fiber, magnesium, boron, folate, antioxidants such as vitamins C and E, carotenoids, and phytochemicals (27-30). Some vegans may have intakes for vitamin B-12, vitamin D, calcium, zinc, and occasionally riboflavin that are lower than recommended (27,29,31).
-------
And they would have to take pills to make up the difference (or use an animal product).
-------
Anyway, it sounds far easier to just eat the way nature intended.
