1, too much fat intake
Beijing Men's Hospital experts pointed out that all kinds of animal meat, especially fat pork, are more fat food. Eat more body fat is bound to increase, fat will reduce the intestinal can be combined in the calcium, thus causing an increase in the absorption of oxalate, no one will know how they will get kidney stones, if once there is a malfunction of the excretory function, such as sweating, drinking less water, less urine, kidney stones are likely to be formed in this case.
2, purine metabolism malfunction
Animal offal, seafood, peanuts, beans, spinach, etc., all contain more purine components. Purine into the body, to be metabolized, it metabolism of the end product is uric acid. Uric acid can contribute to the precipitation of oxalate in the urine. If, once too much to eat a purine-rich food, purine metabolism is out of order, oxalate will be deposited in the urine and the formation of urinary calculi.
3, sugar increase
Sugar is an important nutrient for the human body, often in moderation to supplement, but too much at once, especially lactose, will also make the stone formation conditions. Experts have found: whether normal or stone patients, after consuming 100 grams of sucrose, over 2 hours to check their urine, found that the concentration of calcium and oxalic acid in the urine have risen, if you are taking lactose, it is more able to promote the absorption of calcium, is more likely to lead to the accumulation of calcium oxalate in the body and the formation of urinary calculi.
4, too much oxalic acid.
Experts say that a large accumulation of oxalic acid in the body is one of the factors leading to kidney and urinary stones. Such as spinach, beans, grapes, cocoa, tea, oranges, tomatoes, potatoes, plums, bamboo shoots and other things that people generally love to eat, it is the high oxalic acid-containing food.
5, protein excess
The kidney stone composition of laboratory analysis, found that the stone in the calcium oxalate accounted for 87.5%. The source of such a large proportion of calcium oxalate is because the protein contains oxalic acid in addition to the raw materials - glycine, hydroxyproline, protein can also promote intestinal function of calcium absorption.
