Although soybeans contain a lot of protein, they have few types of amino acids and contain 7-10 types of protein digestion inhibitors, which hinder the digestion and absorption of soybeans and also produce a large amount of gas, causing bloating. Therefore, the view that eating more soybeans can supplement protein is incorrect.
This is because, although soybeans are rich in protein, they lack a variety of amino acids and contain 7-10 types of protein digestion inhibitors, which impede the digestion and absorption of soybeans and also lead to excessive gas and bloating.
What's more, the protein digestion inhibitors in soybeans not only make the protein in soy products themselves difficult to digest, but also affect the digestion of other foods. Therefore, soy products should not be consumed in excess.
Protein is a nutrient essential for the human body to grow tissues and organs and repair damage.
Milk, eggs, lean meat, and poultry are the best sources of protein because these foods contain the essential amino acids (amino acids that the human body cannot synthesize) that the body needs.
A portion of protein can also be obtained from fruits, vegetables, grains, and legumes, but the proteins in these foods do not contain a complete range of amino acids and must be consumed in combination with foods that have a full spectrum of amino acids.
