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.

People with acute gastritis and chronic superficial gastritis should not eat soy products, so as not to stimulate excessive gastric acid secretion and aggravate the condition, or cause flatulence. Beans contain a certain amount of oligosaccharides, which can cause belching, bowel sounds, abdominal distension and other symptoms, so 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 increase the burden on the kidneys, so they should be fasted.
