1, high oxalic acid food The large accumulation of oxalic acid in the body is one of the factors that lead to oxalic acid stones. Foods high in oxalic acid include spinach, beans, grapes, cocoa, tea, oranges, tomatoes, potatoes, plums, bamboo shoots, etc. People generally love to eat these foods. Eat less high oxalic acid food, appropriate supplementation of vitamin B6 tablets, conducive to the removal of oxalic acid. 2, high protein food Frequent excessive intake of high protein food will increase calcium, oxalic acid and uric acid in the kidneys and urine, and if the excess calcium, oxalic acid and uric acid cannot be excreted from the body in time, it will lead to kidney stones and ureteral stones. The daily protein intake should be 1 to 1.2 (g/kg body weight). Breakfast or dinner intake of eggs and milk, etc., basically meet the body’s protein requirements for the day. Properly reducing the intake of animal foods is especially important to prevent the occurrence of kidney stones. 3, high sugar food Although sugar is an important nutrient for the body, a high sugar diet can increase the risk of urinary stones by increasing urinary calcium excretion, especially lactose, which promotes calcium absorption and leads to the formation of kidney stones by the accumulation of calcium oxalate in the body. The higher the intake of sugar, the higher the risk of stone formation. Excessive sugar intake can lead to obesity, which in turn can increase the risk of kidney stones. Try to eat less or no pure sugar food, such as white sugar, brown sugar or by containing these sugar drinks and desserts, etc., staple food to do coarse and fine mix. 4, high-fat food Meat, especially fatty meat contains a lot of fat. Fat will reduce the intestinal tract can be combined with calcium, increasing the absorption of oxalate. Especially when sweating a lot, drinking less water and urinating less, it may accelerate the formation of kidney stones. Eat less fatty meat and limit your daily consumption of oil to 25 grams. Drink more water in summer. When you eat food with a lot of oil and water, you should also drink more water to promote urination, dilute the urine components, do not let oxalate and other components “hold unity block” to reduce the risk of kidney stones. 5, high purine food animal offal, seafood, thick meat soup, peanuts, beans, spinach, etc., all contain more purine components. After the purine enters the body metabolism, its end product is uric acid. Uric acid can contribute to the precipitation of oxalate in urine. Excessive consumption of purine-rich foods at one time can lead to malfunction of purine metabolism and oxalate deposition in the urine to form urinary stones. Gout patients and patients with uric acid stones should eat less high purine foods. 6, high sodium food When the diet is high in sodium, it will increase the excretion of calcium in the urine. If calcium is combined with oxalic acid and uric acid, it will increase the chance of stones. Keep your daily salt intake to 6 grams or less. Patients with kidney stones should avoid foods high in salt, such as ham, sausage, salted eggs, soy melon, tofu milk, salsa, etc. People suffering from kidney stones should not consume the above six kinds of food to avoid accelerating the growth of kidney stones and making themselves suffer more.
