What does protein food include?

Protein's food, one kind is milk, livestock meat, poultry meat, eggs, fish, shrimp and other animal proteins; The other is beans such as soybeans, green beans and black beans, as well as plant proteins such as sesame seeds, melon seeds, walnuts, almonds and pine nuts.

Because the types and proportions of amino acids contained in animal protein are more in line with human needs, the nutritional value of animal protein is higher than that of plant protein. The human demand for protein depends not only on the content of protein, but also on the types and proportions of essential amino acids contained in protein.

Extended data:

In plant foods, protein in rice and flour lacks lysine, and protein in beans lacks methionine and cystine. Therefore, eat more mixed foods, and have complementary functions to improve the utilization rate of mixed protein. If proper animal protein is added, the nutritional value of protein in the diet can be improved. Although the content of protein in human milk, cow milk and eggs is low, their essential amino acids are basically the same as human body, so their nutritional value is high.
