1.Pay attention to the intake of dietary fiber: Studies have shown that the intake of dietary fiber is negatively correlated with the incidence of urinary calculi. Increasing the intake of dietary fiber can reduce the amount of calcium oxalate and uric acid in urine.
Grains, tubers, and fresh vegetables are rich in fiber, and a proper combination of coarse and fine foods can help increase the intake of dietary fiber. Eating more fresh vegetables can have a beneficial effect on increasing dietary fiber.
2.Increase the intake of calcium-rich foods: Low calcium can cause bone resorption to be greater than bone formation, and the blood and urine calcium levels increase. It also increases the absorption and excretion of oxalate through the urethra, leading to the deposition of oxalate and calcium, and promoting the formation of urinary calculi. Therefore, it is necessary to increase the intake of calcium-rich foods in the diet, such as milk, fish and shrimp, kelp, and others. Pay attention not to use calcium supplements to prevent urinary calculi, as excessive intake of calcium supplements may increase the risk of urinary calculi.
3.Eat more foods rich in vitamins: Vitamin B6This can reduce the formation of calcium oxalate crystals in urine, and vitamin K can reduce the content of oxalate in urine. Therefore, it is necessary to increase the intake of these two vitamins in the diet. Green vegetables such as clover, spinach, cabbage, and oranges are rich in both vitamins, and eating a moderate amount can help reduce the incidence of urinary calculi.
4.Limit the intake of foods with a large amount of oxalate:Most of the oxalate in urine comes from the metabolism of the body, and a small part comes from food. However, it is still necessary to reduce the absorption of oxalate by the intestines and try to avoid eating foods rich in oxalate, such as chocolate, coffee, and others.
5.Control the intake of animal protein foods:Excessive intake of animal protein can increase the excretion of oxalate and calcium in urine, reduce the excretion of citrate, lower the urine pH, and increase the probability of urinary calculi. Therefore, it is necessary to control the excessive intake of animal protein in the diet.
6.Avoid eating high-salt foods:The intake of high-salt foods can promote the increase of urinary calcium, while reducing the excretion of citrate, thereby increasing the incidence of urinary calculi. Therefore, when cooking in daily meals, it is necessary to use less salt, eat less salted vegetables, ham, and fried foods to maintain a light diet. At the same time, pay attention to drinking more water to prevent the occurrence and recurrence of urinary calculi.
