Soybeans Bring Health to People
People from eastern countries, especially Japanese and Chinese, like to eat bean products. It is reported that each person in Japan would eat twenty kilograms of bean curd every year. But western people do not eat bean curd or soybeans often. Recently, much research has indicated that soybean is beneficial to health. Experts suggest people to eat more bean products.
Soybean is versatile in health care. First of all, if people ingest more protein from soybeans, the function of cerebral cortex would be strengthened. In other words, the activation and suppression of cerebral cortex will be quickly. In consequence, the working efficiency and study efficiency are improved. And the depressed mood is driven away. Secondly, experts have found that eating soybeans frequently is good for heart. The sterols in soybeans are plant sterols, which are easily to be absorbed by the intestines immediately when they enter the human body. Experts divided the subjects into two groups. Members from group A feed on milk and animal protein, while group B members ingest soybean protein and 500 milligrams of cholesterol everyday. The results showed that the content of cholesterol of group B is reduced by 12%. Obviously, soybean can reduce cholesterol content and is good for preventing cardiovascular diseases and heart diseases. Thirdly, soybean is able to resist cancer. Substances like phytase, plant sterols and isoflavone are effective to restrain the activities of radicals and keep the environment healthy.
Soybeans also bring beauty to people. Japanese women eat soybean paste to whiten their skin. Studies carried out by Japanese researchers have proved that there is a substance in soybean paste. This substance is capable of restraining the production of melanin, which makes skin dark. The ultraviolet radiation would accelerate the exudation of melanin, but oleic acid in soybeans would make black cells turn white. In addition, experts are developing a skin care products made of phytoestrogen. The phytoestrogen is a substance extracted from soybeans. It is similar to isoflavone. It functions well in slowing down aging and do not have side effects, such as inappetency and disordered menstruation. Western experts say that eastern women have more healthy skin because they eat soybeans a lot.
Besides, soybean is able to prevent the human body from acidification. As we know, soybean is rich in phospholipids. More specifically, 85% of these phospholipids are consisted of phosphatidyl choline, phosphatidyl ethanolamine and Phospholipids glycoside, which are useful in protecting human organs. A recent study has shown that there is a large amount of phospholipids in all human tissues and organs. If adequate phospholipids extracted from soybean could be ingested, they would reduce the content of cholesterol and improve the metabolism of lipid. As a result, people can stay away from cerebral and coronary arteriosclerosis. Phospholipids are also helpful for lungs to keep healthy. More importantly, they can promote the absorption of fat-soluble vitamins and prevent the body from acidification.
