Urinary stones diet matters needing attention according to the chemical composition of urinary calculi can be divided into calcium and calci


Urinary stones diet matters needing attention according to the chemical composition of urinary calculi can be divided into calcium and calcium stones. Calcium stones accounted for 80-95%, mainly composed of calcium oxalate and calcium phosphate. In addition to a large number of drinking water, must be adjusted according to the composition of stone diet. 1 calcium oxalate stones: eat: carrots, spinach, celery, lettuce, plum, citrus, beans and chocolate; avoid drinking: beer, cola, cocoa, Black Tea etc.. 2 calcium phosphate and magnesium ammonium phosphate stones: a low calcium phosphate diet and should eat acidic foods. The proposed control of urinary tract infection; should not eat all dairy products, beans, egg yolk and phosphoric acid of lemon juice, cola, coffee etc.. 3 high urinary calcium stones: it is recommended to adopt acid diet, and reduce calcium intake, daily dairy products should not exceed 300cc. 4 uric acid stones: recommended alkaline diet. Suitable for: food grains should take flour and rice; eating more fresh fruits and vegetables; egg and milk intake may be appropriate. Restriction of protein intake. Do not use food: the liver, brain and kidney and other animal offal, jerky various broth, gravy, or salted fried food; seafood: herring, sardines, white fish, clams, crab etc.; vegetables: spinach, cauliflower, asparagus, mushrooms and beans; drink wine, strong tea and coffee cocoa, etc.; 5 cystine stones: low methionine diets. Eat less meat, eggs and dairy products. Effect of diet composition on the stone: 1, water: chronic dehydration and inadequate water formation is closely related to urolithiasis. Increase water can reduce the risk of urinary stone formation through a variety of mechanisms. The reasonable amount of drinking water is not less than 2 liters per day, with particular attention to the evening drink a certain amount of water, sleep at night to add sufficient amount of liquid is very important. It is reported that drinking 2500ml liquid every day can prevent the occurrence of new calculus in high calcium. Usually recommended every 4 hours of Drinking Water 250ml, plus each meal 250ML. As for what kind of liquid to drink, it is agreed that the use of liquid milk without oxalic acid is appropriate. About to drink hard water and soft water still disagree, did not confirm is more likely to cause urinary stone formation hard water soft water. And the results showed that there was a negative correlation between water hardness and kidney stones. Therefore, drinking water is the key, and must be taken into consideration. 2, calcium: it has been confirmed that the general practice of limiting dietary calcium, not only can not reduce, but will increase the risk of kidney stones formation. Low calcium diet can promote intestinal oxalate absorption and induced by hyperoxaluria, so as to promote the formation of urolithiasis. There are reports of low calcium diet in patients with urinary stones, often more harmful than normal calcium diet. But studies have shown that the risk of postmenopausal women will not increase calcium stone formation, even if there is danger, will occur only in the first few months of calcium. This period is best to increase the amount of drinking water. 3, oxalate: since most urinary stones contain oxalates, thus reducing urinary oxalate will reduce the incidence of urolithiasis. However, the majority of ordinary diet, oxalic acid content is low, and the absorption rate is not high, under normal circumstances, the diet of oxalic acid is only 8-12% absorbed. High oxalate urinary calculi so no intestinal disease, limit the intake of oxalic acid There's no telling. The absorption of oxalic acid is increased only when there is insufficient or lack of intestinal bacteria. Metabolites of vitamin 25-30% C urinary oxalate, vitamin C plays an important role in the formation of urinary oxalate and urolithiasis. Although the recommended dose of vitamin C is 60mg/d, but some people for a variety of reasons, a large number of vitamin C. However, the current intake of vitamin C can significantly increase the excretion of urinary oxalic acid, leading to the formation of urinary calcium oxalate stones are still objections. Therefore, urinary calculi were treated with large doses of vitamin C should still be cautious, and avoid tea, do not eat lots of chocolate and spinach. 4, protein: urolithiasis occurrence and rich life, which is associated with high protein diet. Studies have shown that high protein diet can increase the incidence of urinary stones. On the contrary, no animal protein diet is high oxalate containing vegetables, but the risk of the occurrence of a low stone. Therefore, the control of food protein, especially animal protein, is beneficial for all patients with stones. 5, salt: Generally speaking, patients with urinary stones and control in the salt habits of basic no difference. However, studies have suggested that high sodium diet can increase the tendency of urinary calcium salt crystallization. The amount of salt in the diet should be less than 10g/d. 6, fat: excretion in urine of patients with urinary calculi in which calcium quality is higher than that of normal people, but it has nothing to do with diet. But the Eskimos of coronary artery disease and the incidence of kidney stones are low, which with their intake of polyunsaturated fatty acids on non. 7, wine: moderate alcohol consumption does not increase the risk of stone formation. Although the high urinary calcium and high urinary phosphorus long-term drinking is more obvious, but due to the diuretic effect of wine can reduce the concentration of urine composition. 8, citrate citrate is a natural inhibitor of urolithiasis. The following fruits containing citric acid rich: citrus, grapefruit, pineapple. Citrus is common used as auxiliary treatment of low calcium citrate renal calculi. But a high intake of fruits and vegetables containing citric acid can lead to hyperoxaluria and offset the increase the benefits of citric acid in the diet. Of all kinds of food: acidic food: rice, table cereals wheat, sorghum, corn, potato, sweet potato, taro, cassava flour, noodles, macaroni eggs: egg, duck's egg, preserved egg, Mei Zi. Alkaline food: milk milk, cheese, ice cream fruit: oranges, vegetables, radish, grape, olive brown sugar water chestnut stem. Neutral food butter, vegetable oil, peanut oil, sesame oil, tea, coffee, sugar, pig nuts: peanuts, walnuts, cashews and almonds.
