We don't just have to eat soy beans to get protein or iron. There are plenty of foods we can eat to obtain more than enough protein. The protein found in meat is more plentiful than the protein in a soy bean. But the protein in soy beans is better for you. Quality over quantity. From Wikipedia:
The American Dietetic Association, the largest organization of nutrition professionals, states on its website "Vegetarian diets offer a number of nutritional benefits, including lower levels of saturated fat, cholesterol, and animal protein as well as higher levels of carbohydrates, fiber, magnesium, potassium, folate, and antioxidants such as vitamins C and E and phytochemicals. Vegetarians have been reported to have lower body mass indices than nonvegetarians, as well as lower rates of death from ischemic heart disease; vegetarians also show lower blood cholesterol levels; lower blood pressure; and lower rates of hypertension, type 2 diabetes, and prostate and colon cancer." The American Heart Association's website states "Many studies have shown that vegetarians seem to have a lower risk of obesity, coronary heart disease (which causes heart attack), high blood pressure, diabetes mellitus and some forms of cancer.
Vegetarians get all the protein and amino acids they need from eating a normal variety of whole grains (whole wheat bread, oatmeal, brown rice), beans, nuts, and soy (tofu, veggie burgers/hotdogs, edamame, etc). The lower protein intake of vegetarians has been suggested as a possible cause of some of the health benefits above.
Actually, that's a funny thought: I go for approximately 180grams of protein per day. Imagine the amount of beans, nuts, wholegrains, eggs and tofu I'd have to eat to get that :laugh:
As you'll see here:
http://www.peakperformance.on.ca/health/1protein_myths.htm Not that much.
And even if I didn't need that much protein, I'd certainly still make meat a part of my daily diet. Heck, I hunt moose and small game in the fall. Its completely natural for humans to eat meat. Certainly more natural than it is for humans to
not eat meat.

Plus, it does point out that vegetarians in general are slighter. Meat (with exercise) allows you to put on lean muscle. I certainly wouldn't want to be slighter, due to not eating enough of the right things. If you exercise enough (like anyone should) the fat and cholesterol consumed is burned off by your metabolism anyways. And to be more fit you need some amount of muscle, and meat is necessary for that.
No it's not necessary for that. A vegetarian can gain as much muscle mass as a meat eater. An there not "slighter" due to eating the wrong things, it's the total opposite. Their not filling themselves with fat like meat eaters do, that's why they are slimmer an healthier. An that's not an opinion, it's scientific fact. As illustrated in my previous post.
Anyways, the point of this whole thread is animal suffering. And if being a vegetarian is your way of thinking a veggie diet has nothing to do with animal suffereing, then think again. See the link below:

Yeah, this guy is known for bashing, but he does have valid arguments, in the fact that animals still do suffer, from harvesters, and so on.[/
That guy may be a total moron,but at least he appreciates sarcasm, as illustrated by the name of his web page. His arguments aren't valid. Comparing Animals killed during harvest to Animals being murdered for meat. Is like saying murder is ok, because we have accidental death.
That aside, it still completely scientifically natural for humans to kill animals to eat. Hence, they suffer. Its part of the ecosystem, and of all creation. It actually keeps a healthy balance in the food chain, and the earth's ecosystem.
