Protein Sources...for those who say not eating meat does not allow you to have enough protein.
While just about every vegetarian food contains some protein, the soybean deserves special mention, for it contains all the essential amino acids and surpasses all other food plants in the amount of protein that it can deliver to the human system. In this regard, it is nearly equal to meat. The human body is able to digest 92 percent of the protein found in meat and 91 percent of that found in soybeans. The many different and delicious soy products (such as tempeh, soy “hot dogs” and “burgers,” Tofutti brand “ice cream,” soy milk, and tofu) available in health and grocery stores suggest that the soybean, in its many forms, can accommodate a wide range of tastes.

Other rich sources of non-animal protein include legumes, nuts, seeds, yeast, and freshwater algae. Although food yeasts (“nutritional yeast” and “brewer’s yeast”) do not lend themselves to forming the center of one’s diet, they are extremely nutritious additions to most menus (in soups, gravies, breads, casseroles, and dips). Most yeasts get about 50 percent of their calories from protein.
