The formation of urinary stones has a certain relationship with diet and nutrition, especially bladder stones have a more obvious relationship with nutrition. Epidemiological surveys have shown that the incidence of kidney stones is increasing in developed countries, while the incidence of bladder stones is decreasing. Some foods can promote stone formation, such as purine-rich animal offal, oxalic acid-rich spinach, tomatoes, tea and chocolate. Long-term alcohol drinkers with high urinary calcium and phosphorus are prone to stone formation, while drinking large amounts of water can significantly reduce the occurrence of stones. Calcium salts are the main component of urinary stones. It is generally believed that an increase in calcium intake increases the risk of kidney stone formation. However, excessive restriction of calcium intake will not reduce but increase the occurrence of kidney stones. For calcium oxalate stones, a normal calcium intake of 1000 mg per day for adults and 1200 mg per day for people over 50 years of age needs to be maintained. Since most urinary stones contain oxalate, lowering urinary oxalate will certainly reduce the occurrence of stones. The large accumulation of oxalic acid in the body is one of the factors leading to kidney stones. High doses of vitamin C, strong tea, high consumption of foods high in oxalic acid such as chocolate, spinach, beans, grapes, tomatoes, plums, bamboo shoots, beets, oranges, rhubarb, nuts, strawberries, mushrooms, potatoes, peppers, corn, coffee, cocoa, persimmons and prunes increase urinary oxalic acid levels and lead to the development of urinary stones. Diets high in protein, sugar and fat increase the risk of stone formation. Meat from various animals, especially fatty pork, are fatty foods. Eat more fat in the body is bound to increase, fat will reduce the intestinal can be combined with calcium, thus causing an increase in the absorption of oxalate, if once the excretory function failure, such as sweating more, drinking less water, less urine, kidney stones are likely to be formed in this case. Usually, you should eat more roughage and vegetarian food appropriately. Sugar is an important nutrient for the human body and should be added regularly in moderation, but too much at once, especially lactose, can promote the absorption of calcium, which may lead to the accumulation of calcium oxalate in the body and the formation of urinary stones. In addition to glycine and hydroxyproline, the raw materials of oxalic acid, protein also promotes the absorption of calcium in the intestine. If high protein foods are often consumed in excess, the calcium, oxalic acid, and uric acid content in the kidneys and urine generally increases. If the excess calcium, oxalic acid and uric acid are not discharged from the body through the kidneys in a timely and effective manner, the conditions for kidney stones and ureteral stones will be formed. High urinary calcium and high urinary phosphorus are more obvious in long-term heavy drinkers, and stones are easily formed. On the contrary, diuresis caused by moderate alcohol consumption can reduce the concentration of urinary components and reduce the incidence of stones. In conclusion, moderate alcohol consumption does not increase the risk of stone formation. Animal offal, seafood, peanuts, beans, spinach, etc., all contain more purine components. When purine enters the body, it is metabolized, and the end product of its metabolism is uric acid. Uric acid can contribute to the precipitation of oxalate in the urine. If too much purine-rich food is consumed at one time and the metabolism of purine is malfunctioning, oxalate is deposited in the urine and urinary stones are formed. In addition, drugs related to stones, such as vitamin C, aspirin and sulfonamides, are also likely to form urinary stones when taken regularly.
