1. Soybean is rich in protein, and its content is more than twice that of cereal crops such as wheat and rice, usually between 40% and 50%. ?
Protein is the main source of human nitrogen, which can not only provide some consumed energy, but also be used to synthesize new tissues. Protein accounts for about 17% of the adult's body weight, and 3% of protein participates in metabolic renewal every day.
When protein in the body is insufficient, people's basic life activities will be affected, which may lead to growth retardation, underweight and mental retardation of children and adolescents. Adults have fatigue, weight loss, anemia, decreased plasma albumin, and even edema; It can also lead to menstrual disorders in women. Eating protein powder can effectively prevent or improve these symptoms.
2. As far as amino acid content is concerned, soybean protein is the only plant protein reported at present that contains nine essential amino acids needed by human body and its content meets human needs. It is recognized as a complete protein, and its protein evaluation index PDCAAS (amino acid score corrected by protein digestibility, a method to measure the quality of protein) reaches the maximum value 1, just like casein and egg protein. ?
The food that modern people need should not only arouse their appetite, but also have no adverse side effects and be rich in nutrition. In the existing food group, the crop with the above conditions and rich raw materials is soybean. The beverage made of soybean protein is praised as "green milk" by nutritionists.
4. Soy protein can significantly reduce the cholesterol of people with high cholesterol. The content of arginine in soybean protein beverage is higher than that in milk, and the ratio of arginine to lysine is reasonable. Among them, lipid and linoleic acid are extremely rich and contain no cholesterol, which can prevent cardiovascular diseases in adulthood. Rich in lecithin, it can remove excess sterols from the blood and has the reputation of "vascular scavenger".
5. Soy protein drinks are easier to digest and absorb than milk. Milk is easy to form a big hard lump after entering the stomach, while soybean milk is easy to form a small piece after entering the stomach, and it is soft but not hard, so it is easier to digest and absorb.
These soy proteins are essential nutrients for everyone, but they are mostly insufficient through daily diet, and must be supplemented by eating protein powder, especially for some special groups such as children, pregnant women, nursing mothers and the elderly.
Extended data:
Harm of excessive intake of soybean protein;
1. Excessive intake of protein is harmful to human health. There are many decomposition products of protein in human body, among which ammonia, ketoacid and urea will have side effects on human body, which will not only increase the burden on the liver, but also easily cause indigestion, which will affect the function of liver and kidney for a long time, leading to emaciation and low immune function.
2. American scientists issued a statement that eating too much protein will increase the risk of cancer, such as rectal cancer, pancreatic cancer, renal cancer and breast cancer. Patients with gout and liver and kidney failure should also limit the intake of protein.
3. Medical experts also stressed that patients should not blindly choose protein powder supplements. "Ordinary surgical patients need more nutrition, rather than relying solely on protein to help repair tissues. For patients, especially those with kidney disease, it is not advisable to eat too much protein powder, otherwise it will easily lead to metabolites aggravating the burden on liver and kidney.
