Vegetables - beans included - are not a "complete protein" and must be combined specifically with other products - grains for instance - in specific combinations in order to make up the same protein compounds one would get from meat products. This is why so many folks who jump into vegetarianism without doing proper research/reading end up with health problems. It's not as simple as just subbing vegetables willy-nilly for meat.
Breezy, you're correct in saying that specific vegetables, legumes, etc don't offer complete protein, meaning they don't possess all the amino acids that our bodies need and can't manufacture. But the solution is quite simple.
What that means is you need to eat a variety of foods. I don't mean at every meal or even every day, I mean in general. Eat a variety of beans, grains, vegetables, etc and you WILL get the protein and the amino acids you need. Beans are a good substitute for animal protein, just not the substitute.
I don't eat animal protein at all. I have done my research and I see my doctor regularly. A vegetarian with a poor diet will have health problems just as an omnivore with a poor diet will have health problems.
