Is drinking soybean milk nutritious for the body?
Soybean milk and nutritious soybean milk are bought and drunk by many people every day, but what nutrition does soybean milk contain? How to drink soybean milk is the most scientific? Soymilk is a drink ground after soaking soybeans, which can be drunk directly and made into bean products. The nutrition of soybean milk comes from soybean. The protein content of soybean is very high, about 35% ~ 40%, which is two or three times higher than the protein content of various meats. In addition to various trace elements and minerals such as protein, calcium and iron, soybean also contains stigmasterol, unsaturated fatty acids and lecithin, which can help people reduce the concentration of cholesterol in blood and prevent various cardiovascular and cerebrovascular diseases and other chronic diseases. Soybean is rich in nutrients, but only through full processing can these nutrients be absorbed by the human body. For example, the protein digestibility of dry fried soybeans is generally 48%, while the digestibility of whole cooked soybeans is only 65%. After soybean is soaked, ground, made into soybean milk and fully heated, the digestibility of soybean protein can be increased to 90% at once. The nutritional value of soybean milk is increasingly accepted by people all over the world. Europe calls it "plant milk", while the retail sales of soybean milk in the United States has exceeded 300 million US dollars. However, as we all know, food with high content in protein is easy to deteriorate, while soybean milk is generally cooked, sold and drunk, which makes soybean milk exposed to the air for a short time, not to mention the opportunity for all kinds of microorganisms to fully move, so the protein it provides is the most hygienic. The nutrition in soybean milk can be said to be very rich, but if the processing is unreasonable, these nutrients will not be fully absorbed by the human body, and it will endanger our health. Take boiling soybean milk, for example? There's a lot of learning here. Cooking soybean milk does have a lot of science, but there may be such a situation that many people will feel uncomfortable or have diarrhea after drinking soybean milk. This is because the soybean milk is not cooked thoroughly, and the trypsin and saponin contained in the soybean milk will stimulate the stomach and intestines, thus causing nausea, vomiting and some diarrhea. Generally, when soybean milk is boiled to 80℃, it will have a false boiling phenomenon. At this time, many people mistakenly think that the soybean milk has been cooked. In fact, it needs to be cooked for 3-5 minutes at this time before the harmful substances in the soybean milk can be destroyed and lose their activity. Some people think that soybean milk is a good thing, and milk is also a good thing. Then, if they are cooked together, wouldn't they be more nutritious? If that's what you think, you're wrong. The reason is very simple, because it takes 8 ~10 minutes for soybean milk to be cooked, and if it is cooked for such a long time, the protein and various vitamins contained in it will be seriously damaged, and the nutrition will be lost in vain. Cooked soybean milk will inevitably smell of beans. If you are particularly concerned, what should you do? In fact, the beany smell in soybean milk will be reduced after a long period of boiling. But if someone is particularly concerned, they can adjust it according to their own tastes, such as making salty or sweet soybean milk. In fact, there are many ways to eat salted soybean milk, especially in Shanghai. They put a little seaweed, shrimp skin and vegetable leaves in the soybean milk to make a bowl of nutritious soybean milk. Of course, if you like sweet taste, you can also add some sugar to soybean milk to adjust the taste. It is better for middle-aged and elderly people to put honey into soybean milk instead of white sugar, which is more beneficial to their health. Some people like to wash raw eggs with soybean milk, thinking that this is a good way to kill two birds with one stone, but what is the actual effect? Even if the soybean milk is cooked thoroughly, it is not easy to cook the eggs directly. Besides, the eggs contain a sticky protein, which will affect the absorption and utilization of protein. Therefore, the best way is to beat the eggs into soybean milk and cook them before eating. When drinking soybean milk, we should also pay attention to the combination of dryness and thinness, so that the protein in soybean milk can be more fully absorbed by the human body under the action of starch food. If you eat more vegetables and fruits at the same time, the nutrition will be balanced. Now there are many food shredders on the market, among which there is a special soymilk machine. With their help, you can make your own soy milk at home. In the process of homemade soybean milk, you can also add other kinds of beans such as mung beans and red beans to soybeans. Soybean milk made from these mixed beans has various nutrients that complement each other and is more beneficial to health. If you are too busy to buy soybean milk, let alone make it yourself, just buy instant soybean milk and rinse it with hot water. It tastes good and has a lot of nutrition. It can be said that drinking soybean milk is very beneficial to most people, but for some people, drinking soybean milk should be cautious. Scientifically speaking, babies within 6 months, because their gastrointestinal function development is not perfect, had better not drink soybean milk. There are also some patients with gout or renal insufficiency, so it is not advisable to drink a lot of soybean milk because of the limited demand in protein. Besides drinking soybean milk, there are many ways for us to get soybean protein, such as eating tofu. According to the recommendation of the National Food and Nutrition Advisory Committee, everyone should consume at least about 30 grams of soybean protein every day. That is to say, if you want to eat tofu, it should be150g, that is, about 3 liang. If you eat soy products, it should be 45 grams, which is about 1 two. Drinking soy milk also pays attention to "people can't live without beans for a day", that is to say, in the process of pursuing health, people must eat some soy products every day. Of course, soybean milk has always been a favorite drink, and it is also very beneficial to the human body. However, how to drink soybean milk is more beneficial to the human body? Soymilk is cold, so there is stomach cold, such as people who have poor digestion after eating, love burping and hinder qi, and people with spleen deficiency, such as diarrhea and bloating, don't drink it. At the same time, because soybean milk will produce nucleic acid and uric acid in cells during its metabolism in the body, patients with hyperuricemia can't drink soybean milk either. In addition, patients with poor renal function, renal failure and azotemia should not drink soybean milk, because the vegetable protein in soybean milk will increase the burden on the kidneys.
