Protein content in meat is between 10%-20%, commonly known as lean meat with less fat content and fat meat with more fat content. The protein content of lean meat is more than that of fat meat, which constitutes the amino acid of protein. * * * There are more than 20 kinds, of which 8 kinds cannot be synthesized by human body and must be obtained by ingesting foods containing these 8 kinds of amino acids.
Protein of meat food is completely protein, which can provide all kinds of amino acids needed by human body. When meat protein is digested in human body, the decomposed amino acids can be absorbed.
Step 2: eggs

Whole egg protein can be almost completely absorbed and utilized by human body, and it is the most ideal high-quality protein in food. Every100g of eggs contains protein 12.8g and fat1~15g.
Step 3 fish
The fat content of fish is low, ranging from 1 ~ 10%, and the protein content is 15 ~ 20%. It is a high-quality protein fish with short muscle fiber, soft protein tissue structure, high water content, fresh and tender meat, easy to digest and absorb, and the digestibility reaches 87-98%.
4. beans
There are many varieties of beans, mainly soybeans, broad beans, mung beans, peas and red beans. A high-protein and high-fat bean represented by soybean. Another kind of beans is characterized by high carbohydrate content, such as mung beans and red beans.
