When we think of protein foods, we usually think of animal products like meat, milk, and eggs. And, while it is true that animal foods tend to have more protein than plant foods, that doesn't mean that we don't get protein from the plant foods we eat. But, which plant foods are complete proteins? In other words, which plant foods have all of the essential amino acids that we need? This is good info to know, especially if you're vegetarian or vegan.
