they contain all the essential amino acids and enough of them to build new tissue. Chief sources include meat, milk, fish, and eggs i.e. animal foods. This is because animal protein resembles the amino content of human tissue.
Low biological value proteins come from plant sources. They don’t contain enough amino acids to build tissue. Many plant foods contain most or all of the essential amino acids but not in the quantity required and have a Low Biological Value.
An example of a high biological plant protein is soya. It can build tissue on its own. Soya beans contain a good balance of amino acids but their total protein content is lower than that of meat. The protein of cereal, most beans and vegetables contain all the essential amino acids, but the relative amounts of amino acids in these plant foods is less ideal than the amino acid composition of animal protein. Plant protein is therefore of lower nutritive value than an equivalent amount of animal protein. But plant and animal protein by eating complementary foods at the same meal can increase protein intake:
e.g. bread and cheese Spaghetti Bolognaise (cereal) (meat) Cornflakes with
