Regulating intestines and stomach: protein insolubility of soybean. After being made into natto, it becomes soluble and produces amino acids. Various enzymes not found in raw materials can help digestion and absorption of the stomach due to the production of Bacillus natto and associated probiotics. After fermentation, the protein utilization rate of bean products will increase, and the proportion that hinders digestion and absorption will decrease.
Detoxification and beauty: natto is not affected by strong acid in gastric juice. It can quickly colonize the intestine and produce pyridine dicarboxylic acid, which is helpful to kill and inhibit harmful bacteria and viruses in the intestine. The crude extract of natto is rich in antioxidant components such as lecithin, unsaturated fatty acids, vitamin E, etc., which can effectively reduce blood lipid and cholesterol, remove the peroxide pigment in brain tissue cells, adjust the water-lipid balance between skin cells and skin surface, promote blood circulation, improve skin elasticity, make skin smooth and soft, and achieve the effect of delaying aging.
Regulating blood sugar: it is intuitive that the blood sugar value shows an obvious downward trend after meals. One is that Bacillus natto devours glucose and mucus, and the other is that elastase (or trypsin E) in natto inhibits the increase of blood sugar. It acts on this enzyme contained in pig pancreas, and elastase from pig pancreas has been used as a therapeutic drug for hyperglycemia.
Slimming: Mucin in natto has a similar effect to dietary fiber, which can reduce the body's absorption of fat. In addition, vitamin K2 in natto supports fat burning in the body and prevents fat from accumulating in the body, thus playing a role in slimming. Bacillus natto can persist in the intestine for about 1 week, which can promote the proliferation of other beneficial bacteria. The nutrients absorbed by the human body become bait for intestinal bacteria and are swallowed up. In addition, nattokinase can burn fat, so it can lose weight. There is also a sticky substance of natto, which plays the role of leaching and wrapping. Therefore, natto is slow and effective in losing weight and will not rebound.
Function of natto
Prevention and treatment of osteoporosis: Bone is composed of vitamin K2 and high-quality protein, which first forms osteoprotegerin, and then forms bones with calcium, accumulating bones and increasing bone density. Natto contains soybean isoflavone and vitamin K2. Soybean isoflavones can prevent the dissolution of calcium in bones, while vitamin K2 can fix calcium in bones. In other words, the combination of soybean isoflavone and vitamin K2 can strengthen bones together.
Regulating blood lipid: Natto can inhibit LDL oxidation in blood, effectively reduce the concentration of total cholesterol and triglyceride, and then reduce the occurrence of atherosclerosis. At the same time, it can inhibit and reduce the synthesis of angiotensin ⅱ, reduce the peripheral resistance of blood vessels, and then achieve the purpose of lowering blood lipid and blood pressure.
Improve menopausal syndrome: Daidzein in natto can supplement the deficiency of estrogen in the body, regulate endocrine, improve menopausal symptoms, and prevent and treat female osteoporosis.
Anti-cancer: Natto contains lignin and trypsin inhibitor, which can inhibit pathogenic Escherichia coli and other pathogenic bacteria, such as Staphylococcus aureus, Salmonella and Listeria. In addition, isoflavones in natto are antioxidant substances that prevent cell oxidation and can further play an anti-cancer role.
Prevention and treatment of thrombotic diseases: natto contains a lot of nattokinase which can dissolve thrombus. It is a fibrinolytic protease that can directly decompose thrombus. The thrombolytic effect of wet natto per gram is equivalent to urokinase 1600IU. The action time of nattokinase on thrombus is as long as 8- 12 hours, while that of urokinase is only 30 minutes. Natto can be taken orally in daily life, which can effectively absorb enough nattokinase, and it can play an important role in regulating capillaries.
