Usage Note

  • Amino acid content is in milligrams, protein value in grams, and are measured per 100g of food weight.
  • Click on column header to sort foods by name or by column's content.
  • Amino-Acid Score:
    • The score is the ratio of the amino acid in the food's protein over the same amino acid in the reference protein expressed in percentage.
    • This score is for determining the limiting amino acid in a food item. A score below 100 indicates that a food's protein is incomplete. However, a score higher than 100 for a particular amino acid does not necessarily mean that a food's protein is complete. Scores of other essential amino acids of the food also have to be 100 or higher for its protein to be considered complete.
    • The limiting amino acid of a food is defined as the essential amino acid present in the lowest amount compared to a reference protein or to human requirements.

Amino Acids

Amino acids are organic compounds that combine to form proteins. When proteins are digested, amino acids are left. The human body requires a number of amino acids to grow and breakdown food.

Amino acids are classified into two groups: essential and nonessential amino acids.

  • Essential amino acids cannot be made by the body and must be supplied by food. These include leucine, lysine, tryptophan, etc. Sources of essential amino acids include milk, cheese, eggs, certain meats, vegetables, nuts, and grains.
  • Nonessential amino acids can be made by the body from the essential amino acids or normal breakdown of proteins. They include aspartic acid, glutamic acid, and glycine, etc.

Complete Protein

A complete protein (or whole protein) is a source of protein that contains an adequate proportion of all nine of the essential amino acids necessary for the dietary needs of humans or other animals. Some incomplete protein sources may contain all essential amino acids, but a complete protein contains them in correct proportions for supporting biological functions in the human body.

Threonine

As an essential amino acid, threonine is not synthesized in humans, hence we must ingest threonine in the form of threonine-containing proteins. In plants and microorganisms, threonine is synthesized from aspartic acid via α-aspartyl-semialdehyde and homoserine.
