The formation of urinary stones is closely related to diet. A reasonable diet can effectively control the occurrence and development of urinary stones, which can be summarized as six taboos. One avoid drinking too little water. The human body has to excrete a large number of metabolites from the urine every day, and at the same time to concentrate the urine as much as possible to reduce the loss of body fluids. According to statistics, the amount of urine excreted by the human body every day is less than 1000 ml, the chance of producing crystals increases significantly, if less than 500 ml is in danger of becoming a stone. Second, avoid excess nutrition. Excessive food intake, resulting in excess nutrition, is an important factor in the formation of urinary tract stones. Because excess nutrition will also increase the chances of stone formation, it is advisable to adjust the diet according to the results of stone and urine analysis, especially animal protein should not be excessive, animal offal should also be eaten sparingly. Three avoid excessive consumption of sugar. Sugar, especially monosaccharide and lactose can promote intestinal calcium absorption, and correspondingly also increase the absorption of intestinal oxalic acid, so patients with stones should eat less sugar is better. Four avoid oxalic acid food. Spinach, lentils, tomatoes, celery contains a lot of oxalic acid, in addition, tofu, chocolate, tea, etc. contains a lot of oxalic acid, calcium oxalate stones patients should eat less or avoid eating these foods. Five avoid excessive drinking alcohol. Drinking alcohol can increase uric acid excretion in the urine and reduce the volume of urine, beer can be a momentary diuretic, but often subsequently cause urine concentration, so stone patients to drink less alcohol is appropriate. Six avoid food too fine. The more refined food is consumed, the more stones are produced in the urine. And coarse food absorption is slow, the excretion of metabolites is also smoother, so urinary stones patients to eat more coarse food as appropriate.
