Bile duct stones are a type of gallstones, a disease that produces stones in the bile ducts and is often associated with excessive intake of high-fat and high-cholesterol foods. Kelp is a common food in life, and its fat content is relatively low, 100g of kelp contains about 0.1g of fat, which is not likely to cause acute attacks of bile duct stones, so patients with bile duct stones can eat kelp in moderation. At the same time, kelp is rich in dietary fiber, which can promote intestinal peristalsis and help patients digest after moderate consumption. Kelp is also rich in minerals, protein, amino acids, iron, carotene, vitamin B1 and other components, which can supplement the body with nutrients. It is beneficial to the health of patients with bile duct stones when consumed in moderation. However, when consuming kelp, patients need to pay attention to the cooking method of kelp, which should be mainly cold and stir-fried, avoiding braising or working with ingredients such as pig’s feet and pork, so as not to be too greasy and affect the patient’s recovery. In daily life, patients with gallstones should pay attention to a balanced diet, and it is recommended to eat more light, vitamin-rich foods, such as celery and oranges. In addition, if the patient also suffers from hyperthyroidism, it is not recommended to eat kelp, which is rich in iodine that can easily affect the recovery of hyperthyroidism.
