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. Soybean not only contains protein, calcium, iron and other trace elements and minerals, but 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 after 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 soaking, grinding, making soybean milk and fully heating, the digestibility of soybean protein can be improved to 90% at once.
In the process of homemade soybean milk, you can also add other kinds of beans such as mung beans and red beans to soybeans. Soymilk made from these mixed beans has various nutrients that complement each other and is more conducive to health.
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, the baby within 6 months, because the gastrointestinal function is not perfect, it is best not to drink soy milk. There are also some patients with gout or renal insufficiency. Due to the limited demand in protein, it is not advisable to drink a lot of soybean milk.
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. In other words, if you want to eat tofu, it should be 150 grams, which is about 3 liang. If you eat soy products, it should be 45 grams, which is about 1.
"People can't live without beans for a day", that is to say, people eat some bean products every day in the process of pursuing health.
Pay attention to drinking soybean milk:
Soymilk has always been a favorite drink and is also very beneficial to the human body. However, soybean milk is cold, so it has stomach cold, such as indigestion after eating, hiccups, obstruction of qi circulation, diarrhea due to spleen deficiency and abdominal distension. At the same time, because soybean milk will produce intracellular nucleic acid and uric acid during metabolism in the body, patients with hyperuricemia can't drink soybean milk. 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.
Soymilk is not suitable for everyone. Chinese medicine believes that soybean milk is cold and slippery, and the stomach is cold. People who feel stuffy, disgusting, belching and swallowing acid after drinking, people who are prone to diarrhea and bloating due to spleen deficiency, people who have frequent nocturnal urination and kidney deficiency should not drink soy milk.
At the same time, drink soy milk should pay attention to:
There are seven taboos for drinking soybean milk.
1, avoid drinking uncooked soybean milk. Uncooked soybean milk contains toxic substances, which will lead to metabolic disorder in protein and cause poisoning symptoms.
2. Avoid beating eggs in soy milk. Mucin in eggs can easily combine with trypsin in soybean milk to produce a substance that the human body cannot absorb, which greatly reduces the absorption of nutrients.
3, avoid rushing to the red pond. When the organic acids in Tanghong combine with protein in soybean milk, it will produce denatured precipitation and destroy nutrients.
4. Avoid hot water bottles. There are substances in soybean milk that can remove scale from thermos bottles. When the temperature is suitable, the bacteria in the bottle will multiply, and the soybean milk will go rancid and deteriorate after 3-4 hours.
5, avoid drinking too much. Drinking too much soybean milk at one time can easily lead to protein's indigestion, abdominal distension, diarrhea and other symptoms.
6, avoid drinking on an empty stomach. If you drink soybean milk on an empty stomach, the protein in soybean milk will be converted into calories and consumed in the body, which can not fully play a nourishing role. Eating some starchy foods such as steamed bread and bread while drinking soybean milk can make the nutrition fully absorbed and utilized.
7. Don't drink with drugs. Some drugs will destroy the nutrients in soybean milk, such as tetracycline, erythromycin and other antibiotics.
