Soybean is one of China’s important food crops, has been cultivated for five thousand years, is a crop rich in plant protein. Yellow soybeans, commonly known as soybeans, that is, a kind of soybean, as a widely popular food crop, folklore circulated so several statements: 1, soybeans are a good source of protein. Soybeans are a protein-rich crop, commonly used in the preparation of various soy products, soybean oil, brewing soy sauce and other foods, as well as an important source of protein extraction. Studies have shown that commercially cultivated soybeans can contain up to 42.62% crude protein, and through testing, soybeans have been found to contain a variety of essential amino acids required by the human body. However, although the protein content of soybeans is rich, but the nutritional value of soybeans is still slightly less than eggs in terms of supplementing human protein. 2, soy can reduce the incidence of cardiovascular disease. Soybeans contain a lot of protein, but also fatty acids, minerals and soy isoflavones and other substances. Soybean oil unsaturated fatty acids account for 80% to 90%, of which linoleic acid accounts for the majority. Linoleic acid, as unsaturated essential fatty acids, has an important protective effect on cardiovascular. Studies have found that linoleic acid is significantly lacking in myocardial phospholipids of patients with dilated cardiomyopathy compared with normal controls, so supplementing the content of linoleic acid in the diet may have a certain impact on the prognosis of dilated cardiomyopathy. In addition, soybeans contain Ca, Mg, Fe, Zn, Cu and other trace elements, and studies have shown that supplementation with Cu, Fe, Mg and other trace elements can lower vascular resistance, reduce platelet aggregation and lower the risk of coronary heart disease. Natural soybeans are rich in soy isoflavones, which play a weak estrogenic activity in living organisms and can therefore improve lipid metabolism after estrogen withdrawal, thus producing a preventive effect on coronary heart disease; there are estrogen receptors on vascular smooth muscle, and phytoestrogens can act directly on vascular smooth muscle and thus participate in the protective mechanism of vascular injury. Many age-related diseases, such as heart disease and cancer, are associated with excessive molecular oxidation. Studies have shown that isoflavones can block oxidative damage to vascular smooth muscle DNA from peroxides in vivo. 3, soy beans are easy to eat gastrointestinal flatulence. Through the above introduction, we recognize the nutritional value and medicinal value of soybeans, especially for cardiovascular disease, seems to be good health ingredients. However, some people say that soybeans eat more, easy to bloat, is this also true? The “Compendium of Materia Medica” mentioned soybeans: “more food congestion, phlegm, moving cough”, for this, Huang Gongxiu “Materia Medica for truth” has a more sophisticated discussion: “all things raw is draining, cooked is congestion, soybeans, although its taste is sweet, although its nature is warm, but raw is water gas is not drained, served more of the harm of draining, so beans must be divided into raw and cooked, and the treatment is the difference between tonic and diarrhea. With the supplement should be false to fry cooked, but must be appropriate to eat less, if you make more to serve is not appropriate, it will see a raw phlegm congestion pneumatic cough of drawbacks.” Therefore, soy beans should not eat more, should also pay attention to its consumption method. The actual diet recommendation] barley corn soybean rice Decoction points: you can first soak soybeans with hot water for more than 4 hours, then change the water cooking. This can dissolve the gas-prone cottonseed sugar family sugars in soybeans to avoid causing stomach flatulence.
