There is a popular misconception that meat is the only real source of protein, and thus that a vegetarian diet is inherently unhealthy due to a lack of protein. It is impossible to stress how untrue this is.

First of all, the Recommended Daily Allowance of protein is not as high as one might think, and many people - vegetarian or not - eat more protein than their bodies actually need. The approximate RDA of protein is only 47 grams for women and 54 grams for men.
