Protein is composed of amino acids. Among the 22 essential amino acids for the human body, 9 amino acids (amino acid foods) cannot be synthesized by the human body or are not synthesized in sufficient amounts and must be obtained through diet.
Protein intake!
Old Man: Same as an adult man
Adult women: 60-100 grams (1-1.5 grams per kilogram of body weight/day)
Adult males: 80-120 grams (1-1.5 grams per kilogram of body weight/day)
Fitness: Weight trainer 150-250 grams (2-2.5 grams per kilogram of body weight/day)
Children under 5 years old: relatively high in terms of weight (1.5-1.8 grams per kilogram/day)
Children aged 5-12 years old: Higher than adults, total protein intake is 1-1.5 grams per kilogram of body weight per day
Protein is also indispensable
Protein is an important raw material for building and repairing the body. The development of the human body and the repair and renewal of damaged cells are all important.Protein is inseparable. For bodybuilders protein is the basic raw material for building muscles. Enough protein can build strong muscles for you.
Protein is the material basis of all life and an important component of body cells,
Every tissue in the human body: hair, skin, muscles, bones, internal organs, brain, blood, nerves, endocrine, etc. are composed of protein, so it is said that diet creates the person himself. Protein is very important for human growth and development.
It is common in China that people do not consume enough protein. Physical fitness is also generally skewed!
Protein food sources of protein can be divided into two categories: plant-based protein and animal-based protein.
Among plant proteins, cereals contain about 10% protein. Beans are rich in protein, especially soybeans, which contain up to 36% to 40% protein. The amino acid composition is also relatively reasonable, and their utilization rate in the body is high. They are a very good source of protein among plant proteins.
In general, animal proteins have higher nutritional value than plant proteins.
High-quality protein comes from our food: eggs, dairy products, beef, lean meat, fish, shrimp, etc. are all excellent sources of protein
