Gallstones are stones produced in the gallbladder or bile duct, commonly caused by the patient’s excessive intake of high-fat, high-cholesterol foods. Since soy milk is low in fat and contains mainly vegetable protein, people with gallstones can consume it in moderation and do not have to worry that it will cause gallstones to attack after drinking it. Since soy milk is relatively rich in calcium, many people worry that it will easily lead to the occurrence of stones after drinking it. However, gallstones are mainly divided into cholesterol stones, bile pigment stones and mixed stones, while calcium stones are very rare. In general, it does not lead to an increase in the number or incidence of gallstones, so patients do not need to worry too much and can drink in moderation. When drinking soy milk, patients should not drink too much. For taste reasons, most commercially available soy milk has some added sugar. If patients consume too much soy milk, their sugar intake will be excessive, which will easily increase their weight and lead to increased gallstones or worsen their symptoms. In daily life, patients with gallstones should pay attention to a balanced diet that is low in fat, low in cholesterol, high in protein, high in vitamins and easy to digest, such as vegetable porridge and shrimp porridge.
