The protein content of soybean is generally 37-48%. Compared with other plants, protein, protein contains more complete amino acids. You can't eat too much. Soybeans are high in oil. It is one of the main oil crops.
nutritional ingredient
Every100g contains protein 36.3g, fat18.4g, carbohydrate 25g, calcium 367mg, phosphorus 57 1 mg, iron 1 1 mg, carotene 0.4mg and thiamine 0.79mg.. It also contains lecithin, soybean soaps A, B, C, D, E and other substances.
Dietetic therapy
1.Enhance immunity
The functional 500g soybean contains protein equivalent to the protein content of1000g lean meat or1500g egg or 6000ml milk. At the same time, it also contains a variety of essential amino acids, which plays an important nutritional role in human tissues and cells and can improve human immune function.
2. Prevent vascular sclerosis
Lecithin in soybean can remove cholesterol attached to blood vessel wall, prevent arteriosclerosis, prevent cardiovascular diseases and protect the heart. Lecithin in soybean can also prevent the accumulation of excessive fat in the liver, thus effectively preventing fatty liver caused by obesity.
3. Promote bone development
Soybean contains a variety of minerals, which can supplement calcium, prevent osteoporosis caused by calcium deficiency and promote bone development, which is extremely beneficial to the bone growth of children and the elderly.
Step 4 guide defecation
Soluble fiber contained in soybean can relax bowels and reduce cholesterol.
5. Anti-iron deficiency anemia
The iron in soybean is not only rich, but also easily absorbed by human body, which has certain curative effect on iron deficiency anemia.
Step 6 reduce blood sugar
Lipid-lowering soybean contains a substance that inhibits pancreatic enzyme and has therapeutic effect on diabetes. Saponins contained in soybean can obviously reduce blood lipid, at the same time, it can inhibit weight gain and reduce lipid content and fat content in serum and liver.
7. Antioxidant and anti-aging effects
Soybean saponin can significantly antagonize the increase of serum alanine aminotransferase and aspartate aminotransferase caused by adriamycin, and has a significant protective effect on the death of mice caused by adriamycin
Precautions for eating
1, soybean is cold, stomach is cold, people who are prone to diarrhea, abdominal distension, spleen deficiency and kidney deficiency who often have nocturnal emission should not eat more.
Do not eat raw, it is poisonous. Eating incompletely cooked soybean milk may cause food poisoning symptoms of different degrees, including bloating, diarrhea, vomiting, fever and so on.
2. Poisoning composition and mechanism: Raw soybean contains a trypsin inhibitor, which inhibits the normal activity of trypsin in the body and stimulates the gastrointestinal tract.
3. At present, the highest boiling temperature of many brands of soymilk machines on the market is not up to 100℃, which is actually not completely cooked. After the soymilk machine grinds, it is heated and boiled in a pot, and the soybeans should be boiled for seven times (or boiled for about 15 minutes) for safe consumption.
Beware of livestock poisoning by eating raw soybeans. However, eating raw livestock is easy to cause bloating and even poisoning, and if the rescue is not timely, it will lead to the death of livestock.
4, soybean skin is thick, and it is not easy to be chewed by teeth. Moreover, raw soybeans contain trypsin-inhibiting toxins, which can reduce the digestion of digestive juice, thus reducing the digestibility of feed, especially dry soybeans, whose digestibility is only about 50%, and whole soybeans are more difficult to digest. In addition, some of the sugars contained in soybeans can be combined to form sticky semi-fiber, which can be fermented in the digestive tract of livestock to produce gas and form flatulence; Soybean becomes raw soybean milk in the stomach, in which saponin can stimulate digestive tract mucosa and destroy red blood cells. Therefore, livestock may have symptoms of poisoning after eating, such as abdominal pain, diarrhea, sweating, stumbling, lying on the ground, chills all over, convulsions and dyspnea.
5. After cattle, sheep, donkeys, horses and other domestic animals eat raw soybeans by mistake, they should strictly control drinking water. If you drink too much water, it is easy to cause acute gastric dilatation, leading to gastric rupture and death. If domestic animals suffer from bloating and food accumulation due to eating raw soybeans by mistake, 500ml of sesame oil, 50g of human hair, and honeycomb/kloc-0 can be burnt into charcoal, mixed with boiled sesame oil, and will be cured soon. In order to prevent cattle and sheep from eating raw soybeans by mistake, we should strengthen the management of domestic animals, especially calves and lambs that have not been put on the cover, so as to avoid poisoning caused by stealing.
6. Soybean contains 1970 mg of purine per 1000 g, which is one of the highest contents in various foods. Excessive consumption of soybeans or frequent consumption of soybeans will increase the purine content in the human body, which will turn into uric acid after oxidation in the human body, and uric acid is too high will cause gout. Therefore, eat soybeans in moderation.
