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 an organism. Not all species require the same amino acids, therefore what may be a complete protein for a human may not be complete for an animal.
Examples of complete proteins are meat, poultry, fish, eggs, milk, cheese, yogurt, soybeans and quinoa. Since the amino acid profile of protein in plant food may be deficient in one or more of the following types, most plant proteins are said to be incomplete. However, mixtures of plant protein sources can provide the complete, balanced amount of amino acids needed for normal physioloical functions and growth.
The following table lists the optimal profile of the essential amino acids, which comprises complete protein, as recommended by the Institute of Medicine's Food and Nutrition Board:
The second column in the following table shows the amino acid requirements of adults as recommended by the World Health Organization calculated for a 70 kg (150 lb) adult. Recommended Daily Intake is based on 2,000 kilocalories per day, which is also an appropriate daily calorie allowance for a 70 kg (150 lb) adult.

Sources of complete protein
- Generally, proteins derived from animal foods (meats, fish, poultry, milk, eggs) are complete.
- Foods that also obtain the highest possible Protein Digestibility Corrected Amino Acid Score (PDCAAS) score of 1.0 are certain dairy products (including whey), egg whites, and soy protein isolate. Other foods, such as amaranth, buckwheat, hempseed, meat, poultry, Salvia hispanica, soybeans, quinoa, seafood, seaweed, and spirulina also are complete protein foods, but may not obtain a PDCAAS score of 1.0.
