Protein as I said, is made up of amino acids. There are 20 amino acids found in the foods we need. Nine of these are called “essential amino acids” because the body NEEDS them. Just like essential fatty acids, the body cannot make these on its own, so it’s “essential” that we get them from our food. (The technical names of these nine essential amino acids are: histidine, valine, isoleucine, leucine, phenylalanine, threonine, tryptophan, methionine, and lysine.)
If a food contains all nine of these essential amino acids, it’s called a “complete” protein. Complete proteins are things like dairy, chicken, beef, fish, and eggs. Foods that do not have all nine essential amino acids are called “incomplete” proteins. These are things like grains, beans, nuts, and seeds. These are NOT “bad” proteins; they are just not complete, meaning they do not contain all of the amino acids that we need.
Some incomplete proteins may contain some essential amino acids but do not have all nine. Or perhaps they have other “nonessential amino acids” (these are not “essential” to consume because our body can make them on its own).
So, when we talk about how important protein is, it’s important to choose the best protein, which is a complete protein. Or, at the very least, you should make sure you are consuming foods that contain various essential amino acids, even if they don’t have all of them. Below is a list of the nine essential amino acids, what they help the body with, and what foods you can find them in. As you can see, complete proteins are important for many reasons.
