Protein-rich foods include animal proteins such as milk, meat, poultry, eggs, fish and shrimp; legumes such as soybeans, green beans and black beans; and plant proteins such as sesame seeds, melon seeds, walnuts, almonds, pine nuts and other dried fruits.

The most protein-rich meat is chicken, which contains 23.3 grams per 100 grams. The most protein-containing plant food is soybeans, containing 36.3 grams per 100 grams; of which spirulina, because of its unique algal blue protein, is considered to be the highest protein content of natural protein foods.

Protein is an essential nutrient, protein accounts for 16% to 20% of the body weight, that is, a 60kg weight of the adult's body about protein 9.6 ~ 12kg. because of the types of amino acids contained in animal proteins and the proportion of the human body more in line with the needs of the type of animal protein is higher than the nutritional value of plant-based proteins.

Expanded Information

Protein deficiency occurs in both adults and children, but children in the growth phase are more sensitive. Common symptoms of protein deficiency are decreased metabolic rate, decreased resistance to disease, and susceptibility to disease, and the long-term effect is damage to organs, commonly in children, growth retardation, malnutrition, loss of body mass, apathy, irritability, anemia, and dry and thin disease or edema, and secondary diseases because of susceptibility to infection.

The rational combination of various foods is an effective way to improve the nutritional value of protein both economically and effectively. Daily consumption of protein is best one-third from animal protein, two-thirds from plant protein. Our people have the habit of eating mixed food, several kinds of lower nutritional value of protein mixed food, which the amino acids complement each other, can significantly improve the nutritional value.
