Amino acids are the building blocks that They build proteins, which your body needs to build muscles, repair organs, create hemoglobin and support the immune system. When you consume protein, your digestive system divides proteins into amino acids used throughout your body. There are 22 amino acids, nine of which you must consume through your diet. Even vegetarians can get the amino acids they need through proper nutrition.
According to KidsHealth, the recommended daily intake of protein is 0.5 grams per pound of body weight, so a 150-pound person needs 75 grams of protein each day. You can consume an adequate amount of protein and get all the essential amino acids while you follow a vegetarian diet. The key is to eat a variety of daily meals. Protein sources of plants include nuts, lentils and beans. Soybeans and quinoa contain both the nine essential amino acids. You do not have to consume all the amino acids in a single meal, as long as you eat a variety of foods throughout the day that provide all the necessary amino acids.
