Patient's question:
Problem Description: What to eat and what not to eat when you have kidney stones in daily life.Doctor's answer:
Six dietary taboos for patients with kidney stones: The formation of kidney stones is closely related to diet. Experts believe that a reasonable diet can effectively control the occurrence and development of kidney stones, which can be summarized into six taboos.1. Avoid drinking too little water. The human body excretes a large amount of metabolic products through urine daily while also concentrating the urine to minimize fluid loss. Statistics show that if daily urine output is less than 1,000 milliliters, the chance of crystal formation significantly increases, and if it is less than 500 milliliters, the risk of stone formation becomes severe.
2. Avoid excessive nutrition. Consuming too much food, leading to nutritional excess, is a major factor in the formation of urinary tract stones. Excessive nutrition also increases the likelihood of stone formation. Patients with stones should adjust their diet based on the results of stone and urine analysis, especially avoiding excessive animal protein. Animal organs should also be consumed in moderation.
3. Avoid excessive consumption of sugars. Sugars, particularly simple sugars and lactose, can promote the absorption of calcium in the intestines and, correspondingly, increase the absorption of oxalate. Therefore, it is advisable for stone patients to limit their sugar intake.
4. Avoid foods high in oxalate. Spinach, broad beans, tomatoes, and celery contain large amounts of oxalate. Additionally, foods like tofu, chocolate, and tea also contain significant amounts of oxalate. Patients with calcium oxalate stones should avoid or limit these foods.
5. Avoid excessive alcohol consumption. Alcohol increases the excretion of uric acid in urine while reducing urine volume. Although beer may temporarily promote diuresis, it often leads to subsequent urine concentration. Therefore, it is best for stone patients to limit alcohol intake.
6. Avoid overly refined foods. The more refined the food, the more stone-forming components it produces in the urine. Coarse foods are digested more slowly, and the excretion of metabolic products is more stable. Therefore, it is recommended for patients with kidney stones to consume more coarse grains appropriately.
