Soybean milk is a traditional food made from soybeans. It has the reputation of “plant milk” and is very popular among Chinese people. So, what exactly does soy milk do?
First, let’s analyze the nutritional content of soy milk. The main raw materials of soy milk are soybeans and water, and a small amount of sugar or salt can be added according to personal preference. The nutritional value of soybeans is high in the following aspects: First, soybeans contain a large amount of protein, up to 40%, more than pork and eggs (pork protein is 13.2g/100g, egg protein content is 13.3g/100g). Soybean contains 8 essential amino acids. Although the content of methionine and cysteine is low, the content of the remaining amino acids all meet or exceed the requirement level recommended by the World Health Organization (WTO) [1]. People can supplement the protein and amino acids they need by eating soybeans. Especially for obese people, taking part of the protein through soy can avoid eating too much meat and increase cholesterol. 2. Soybean contains about 10 kinds of mineral elements [1], such as calcium and potassium, among which the potassium content is as high as 1403mg/100g, and the calcium content is about 470mg/100g, which is about 8 times the calcium content of milk. Eating soy provides sufficient minerals, including calcium, which is good for lowering blood pressure. 3. As one of the coarse grains, soybean is rich in dietary fiber (about 20%), and dietary fiber can promote gastrointestinal motility and improve gastrointestinal symptoms such as constipation. Fourth, the isoflavones and saponins contained in soybeans are beneficial active substances in the human body, which are beneficial to reduce the risk of cardiovascular and cerebrovascular diseases and cancer [1]. It can be seen that eating soybeans can supplement the essential nutrients such as protein and minerals in the human body, and is also beneficial to reduce the risk of hyperlipidemia, hypertension and other diseases.
Since soybeans are so rich in nutrients, does soy milk have many magical properties? The answer is no. This involves the issue of soybean content in soy milk. The ratio of soybeans and water in soymilk is about 1:12, that is, 100ml of soymilk contains only about 7g of soybeans. People generally drink 300~500ml of soymilk a day, and the amount of soy ingested is only 21~35g. From the above, it can be seen that the nutrients contained in such a small amount of soybeans will not be enough to exert its “effect”. That is to say, drinking soy milk can indeed supplement nutrients such as protein necessary for the human body, and is also conducive to reducing the risk of disease. The risk of chronic diseases such as high blood lipids, but due to the limited amount of daily intake, its effect on the human body has not risen to the point of miraculous effects. In one sentence, drinking soy milk is beneficial to human health, but the main function of drinking it is to supplement the water needed by the human body. If you want to absorb the nutrients in soy through soy milk to achieve the effect of soy , it’s a bit wild. As for whether soy milk is alkaline food or acidic food, the answer is alkaline food. However, since the acidity and alkalinity in the human body do not change under normal circumstances, the concept of alkaline food/acidic food is outdated, that is to say, whether the soy milk is alkaline or acidic has nothing to do with its nutritional value. , and it has nothing to do with the so-called efficacy.
