Soymilk, cheap and nutritious, is one of people's favorite breakfasts. Many families grind their own. It should be noted that raw soybean milk is toxic. This is because raw soybean milk contains a soap toxin, which can poison people and cause nausea, vomiting, abdominal pain, diarrhea and other symptoms. In addition, there is an antitrypsin in raw soybean milk, which can reduce the ability of gastric juice to digest protein. So soybean milk must be boiled before it can be eaten. It should also be noted that "fake cooking" often occurs when cooking soybean milk. That is, when soybean milk is heated to 80 degrees Celsius, bubbles will appear, and with the increase of temperature, more and more bubbles will appear. Some people think that soybean milk has been cooked. In fact, this is the foam produced by heating soybean milk, that is, "false boiling", and soybean milk does not really boil. The correct cooking method is: when cooking soybean milk, don't fill the container too full to prevent the foam from overflowing when cooking soybean milk. When cooking, use strong fire first. When the foam overflows, cook over low heat until the foam gradually disappears. At this time, the temperature of soybean milk has reached 100 degrees Celsius, and both soap toxin and antitrypsin have been destroyed. While other nutrients remain unchanged. In addition, when cooking soybean milk, don't add raw soybean milk casually. Soymilk bought from the street should also be boiled before eating, so as to avoid poisoning of raw soy milk. On the other hand, the nutrients in honey will be destroyed at high temperature, so don't cook with soybean milk. After the soybean milk is cooked, add honey and cool until it is not hot.
■ Special reminder ★ Patients with acute gastritis and chronic superficial gastritis should not eat soy products, so as not to stimulate excessive gastric acid secretion to aggravate the condition or cause flatulence. ★ Beans contain a certain amount of oligosaccharides, which will cause belching, bowel sounds, abdominal distension and other symptoms. Friends with gastric ulcers had better eat less. Patients with gastritis and renal failure need a low-protein diet, while beans and their products are rich in protein, and their metabolites will increase the burden on the kidneys, so they should be fasted. ★ Oxalate in beans can combine with calcium in kidney, which is easy to form stones, which will aggravate the symptoms of kidney calculi, so kidney calculi patients should not eat it. ★ Gout is a disease caused by purine metabolic disorder. Soybean is rich in purine, which is a hydrophilic substance. Therefore, after soybean is ground into pulp, the purine content is several times higher than that of other bean products. So soybean milk is not suitable for gout patients.
