Nutrition and health care of soybean
Soybean protein contains more lysine and less methionine. In rural areas dominated by plant foods, attention should be paid to the use of soy products with foods rich in methionine, such as rice, flour and other cereals and eggs such as chickens, ducks, pigeons and quails, which can improve the utilization rate of soy protein. When eggs and beans are eaten together, their nutritional value is comparable to that of meat protein.
Soybean contains a fatty substance called linoleic acid, which can promote children's nerve development. Linoleic acid can also lower blood cholesterol, so it is a good food to prevent hypertension, coronary heart disease and arteriosclerosis. In addition, soybean is rich in B vitamins and inorganic salts such as calcium, phosphorus and iron. Although dried soybeans do not contain vitamin C, they can produce vitamin C after germination, which can be supplemented in the off-season of vegetables. Raw soybean contains antitrypsin factor, which affects the absorption of nutrients in soybean. Therefore, the cooking time of soybeans and foods made from soybeans should be longer than that of ordinary foods, and these factors should be destroyed by high temperature to improve the nutritional value of soybean protein.
The protein content of soybean is as high as 40%, and the quality can reach about 50%, which is more than twice that of lean pork and three times that of eggs. The amino acid composition of soybean protein is close to the amino acid needed by human body, and it belongs to complete protein, in which lysine content is more. Every100g of soybean contains about 35.8mg of iron, 418mg of phosphorus, and vitamin a b 1 b2 d e, etc.
Modern medical research believes that soybean contains no cholesterol, which can reduce the occurrence of atherosclerosis and prevent heart disease. Soybean also contains a substance that inhibits pancreatic enzyme, which has certain curative effect on diabetes. Therefore, soybean is recommended by nutritionists as an ideal health care product to prevent and treat coronary heart disease, hypertension and atherosclerosis. Soft phospholipids contained in soybeans are an important part of brain cells. Eating soybeans often plays an important role in increasing and improving brain skills.
