Protein sources that provide all the amino acids that cannot be manufactured in the body are considered

Complete

Explanation:

Complete proteins (or high biological value proteins), are those that contain all the essential amino acids (one that the organism is unable to synthesize but is necessary for its functioning) in optimal amounts and proportions to meet organic needs.

A incomplete protein (or low biological value protein), does not have one or more essential amino acids in sufficient quantities.

The main sources of complete protein are eggs, milk, meat, fish and poultry. The essential amino acid mixture present in eggs was considered to be the best among food sources.

Most vegetable proteins (lentils, beans, peas, soybeans), in turn, are incomplete in terms of protein content and therefore have a relatively lower biological value.
