Is getting protein from only vegetarian sources sufficient?
According to Professor Fredrick Stare of Harvard University (USA), if vegetarians acquire 80 grams of protein per day, they will have enough protein in their diet. Proteins are made from 20 amino acids, regardless of whether the protein is from a plant or an animal. Only 9 amino acids are not produced by the human body. Beans such as soy, lack the necessary amino acid methonine, and grains such as rice and wheat lack lysine. However, if one consumes beans and grains together, all 20 amino acids can be consumed, and, furthermore, extra protein that cannot be obtained by animal products alone can be acquired. Of course, vegetarians who eat eggs and dairy products do not have concern themselves with this.
