Plant protein powder is a nutritional food supplement for specific people. As an amino acid supplement food, it can provide essential nutrition for infants, the elderly, sports people, patients before and after operation and people who lose weight due to lack of protein. The function of protein powder. 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. Babies, teenagers, pregnant women and lactating women should not only maintain the protein renewal of tissues, but also synthesize new tissues. 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. Heart disease is the main cause of death in western developed countries. High plasma cholesterol is the main cause of heart disease.

Animal fat in the diet will increase the content of plasma cholesterol, which is an important factor leading to arteriosclerosis and heart disease. Excessive saturated fatty acids, cholesterol and blood cholesterol are directly related to heart disease. Lowering plasma cholesterol will reduce the risk of heart disease. During the period of 1982, scientists from many countries used soybean protein instead of animal protein to treat patients with high cholesterol. The results showed that the content of total cholesterol in plasma decreased by 20% when 50 grams of soybean protein was ingested every day. This study proves that soybean protein can reduce the adverse effects of blood lipid and cholesterol on the heart of patients with high cholesterol. In the United States, doctors advise heart patients to eat soy protein before taking cholesterol-lowering drugs. Because soybean protein is neither medicine (no toxic side effects) nor cheap, it can effectively prevent heart disease and has no side effects.
