UNDERSTAND THE DATA
What it means for your diet
This source explains dietary protein and amino acids as a group. The specific USDA identity above remains separate; protein advice is not an intake target or supplement recommendation for an individual amino acid.
Ranking amounts describe foods, not supplement doses. A high rank does not mean you should consume more. Source recommendations and cautions retain their original population and scope.

Dietary Proteins [1]
Source: MedlinePlus, National Library of Medicine. Original health-topic summary, reproduced with attribution.
Protein is in every cell in the body. Our bodies need protein from the foods we eat to build and maintain bones, muscles and skin. We get proteins in our diet from meat, dairy products, nuts, and certain grains and beans. Proteins from meat and other animal products are complete proteins. This means they supply all of the amino acids the body can't make on its own. Most plant proteins are incomplete. You should eat different types of plant proteins every day to get all of the amino acids your body needs.
It is important to get enough dietary protein. You need to eat protein every day, because your body doesn't store it the way it stores fats or carbohydrates. How much you need depends on your age, sex, health, and level of physical activity. Most Americans eat enough protein in their diet.
