The main reason for the formation of kidney calculi is diet. It is caused by excessive intake of related ingredients that can form stones in the diet. A more detailed explanation is that oxalic acid accumulates too much. The accumulation of oxalic acid in the body is one of the factors leading to nephrolithiasis. Such as spinach, beans, grapes, cocoa, tea, oranges, tomatoes, potatoes, plums, bamboo shoots and other things that people generally like to eat are foods with high oxalic acid content. Through research, doctors found that 200 grams of spinach contains 725.6 mg of oxalic acid. If a person eats all 200 grams of spinach at one time, 8 hours after eating, the excretion of oxalic acid in urine is 20-25 mg, which is equivalent to the average total amount of oxalic acid excreted by normal people in 24 hours. Purine metabolism disorder. Animal viscera, seafood, peanuts, beans, spinach, etc., all contain more purine components. After purine enters the body, it must be metabolized, and the final product of its metabolism is uric acid. Uric acid can promote oxalate precipitation in urine. If the food rich in purine is eaten too much at one time, and the metabolism of purine is abnormal, oxalate will be deposited in the urine to form urinary stones. Too much fat intake. The meat of all kinds of animals, especially fat pork, is a fatty food. Eating more body fat will inevitably increase, and fat will reduce the calcium that can be combined in the intestine, thus causing the absorption of oxalate to increase. If there is a failure of excretion function, such as sweating more, drinking less water and urinating less, kidney calculi is likely to form in this case. Therefore, doctors often say that in order to prevent lithiasis, drink more water in hot weather, and drink more water when eating oily food to promote smooth urination and dilute urine components, thus reducing the risk of getting stones. The sugar is high. Sugar is an important nutrient of the human body, so it should be supplemented regularly and appropriately, but if it is added too much at once, especially lactose, it will also create conditions for the formation of stones. Experts found that no matter normal people or patients with stones, after eating100g of sucrose, they checked their urine for 2 hours, and found that the concentrations of calcium and oxalic acid in urine increased. If lactose is taken, it can promote the absorption of calcium, and it is more likely to lead to the accumulation of calcium oxalate in the body and form urinary stones. Protein overdose. The chemical analysis of kidney calculi components showed that calcium oxalate accounted for 87.5% of the stones. The source of such a large proportion of calcium oxalate is because in protein, besides glycine and hydroxyproline, protein can also promote the absorption of calcium by intestinal function. If you often eat too much food with high protein, the components of calcium, oxalic acid and uric acid in kidney and urine will generally increase. If the excess calcium, oxalic acid and uric acid cannot be excreted from the body through the renal function in time and effectively, the conditions for kidney stones and ureteral stones will be formed. This is the main reason why the incidence rate in kidney calculi, an economically developed country in the world, has increased. Judging from the above factors that are easy to form kidney calculi, in order to prevent the occurrence of kidney calculi's disease, we must change the concept of seeking only one kind of nutrition and pursuing excessive nutrition. That is to say, in human daily diet, we can't just eat a certain food because it is delicious and has high nutritional value. We must pay attention to the collocation of food, and eat all kinds of food in moderation. Even if we check that the body lacks some nutrients and needs some food to supplement it, we should not eat in large quantities at one time, because the digestion and absorption functions of the human body are limited. Nutrients that can't be digested and absorbed will be excreted through the excretory organs, which will also increase the burden on the urinary system. Even if you don't suffer from kidney calculi's disease, it is not good for your health. Especially when it is confirmed to be kidney calculi's disease, during the illness, patients should be restricted from eating foods that are easy to promote the formation of stones. Kidney calculi is a kind of urolithiasis, which is mostly formed in hot summer. Because of sweating in summer and even dehydration in the body, urination is reduced. In addition, exposure to sunlight for a long time in summer helps to increase the synthesis of vitamin D and vitamin A in the body. Vitamin D and vitamin A can promote the absorption of calcium ions in the small intestine, increase the excretion of calcium in urine, and calculus substances in urine are prone to produce crystal nuclei, thus forming stones. When the weather is cold in winter, people's urine volume increases, and the formed small stones are washed away by urine and move down, which causes renal colic symptoms at this time. Therefore, kidney calculi is often characterized by "onset of winter in summer". People's diets are diverse, and human metabolism is complicated, so the composition of kidney calculi is also diverse. Common stones can be divided into five types according to their components: calcium oxalate stones: the most common stones, accounting for more than 80% in kidney calculi, are formed in acidic or neutral urine, and most of them are young adults, especially men. Calcium diphosphate stones: accounting for 6-9% of stones, formed in alkaline urine, and also more common in young men. Uric acid stones: accounting for 6% of stones, formed in acidic urine, and dissolved when the PH value of urine is greater than 6.7, which is more common in men. Magnesium tetraphosphate stones: accounting for 10% of stones, formed in alkaline urine, and dissolved when the urine PH value is less than 7.2, which is more common in women. Cystine stones: rare, accounting for about 1-2% of stones, formed in acidic urine, and dissolved when the urine PH value is greater than 7.0. Drinking plenty of water can prevent and treat all kinds of urolithiasis. In hot summer, when the daily urine volume is less than1200ml, the risk of urinary stone growth increases significantly. If you can make the daily drinking water at 2000-4000 ml, you can maintain the daily urine volume at more than 2000 ml. Magnetized water is more effective for the prevention and treatment of calcium oxalate stones, and the daily drinking water can be given at morning, between meals and before going to bed. Drinking water in the morning can reach 500- 1000 ml. In order to maintain the amount of urine at night, drink 500 ml before going to bed, 300-500 ml after getting up to urinate during sleep, and take the rest of the water between meals. Drinking plenty of water can promote the discharge of small stones, and diluting urine can prevent the formation of urinary stones crystals and delay the growth rate of stones. 1985 Vehlensieck, a foreign scholar, believed that drinking more water and diet therapy could prevent 2/3 patients with recurrent stones from regenerating new stones. Here are some dietary therapies in kidney calculi. ⑴ Calcium oxalate calculus: low calcium and low oxalic acid diet should be adopted. Eat less milk and dairy products, bean products, meat, animal internal organs (such as liver, heart, kidney, intestine, etc.), as well as chocolate, strong tea, sesame sauce, egg yolk, mushrooms, spinach, shrimp skin, radish, cocoa, celery, potatoes, etc. In recent years, it has been found that cellulose in food can reduce the formation of urinary calcium, such as wheat bran bread and rice bran in wheat bran food, and it is effective for recurrent high-calcium urinary calculi. The lack of vitamin B 1 and vitamin B6 increases urinary oxalic acid, so foods rich in these vitamins, such as grains, dried fruits and hard fruits, should be increased. ⑵ Calcium phosphate stone and magnesium ammonium phosphate stone: Its low-calcium diet is the same as calcium oxalate stone. Among low-phosphorus foods, meat, fish and bone soup should be eaten less. ⑶ Urolithiasis: The intake of protein should be limited, and the daily total intake of protein should be between 48-80g (0.8-1.0g/kg/day). Generally, leafy vegetables contain about10g of protein per catty, lean meats contain about 50g of protein10g, and cereals contain 35g-60g of protein per catty. We should increase the consumption of fresh vegetables and fruits. Vegetables and fruits contain vitamin B 1 and vitamin C. Their final metabolites in the body are alkaline, and uric acid is easily dissolved in alkaline urine, so it is beneficial to treatment. Routine treatment: Take a cool diet (raw fruit, juice and lettuce) once every 1-2 days, at least once a week 1 time. Eat less or avoid meat, animal offal, broth, gravy, sardines, crabs, spinach, strong tea and coffee, and use less strong spices and condiments. In real life, the occurrence of many diseases is closely related to the daily diet. If we can live in a proper way, sometimes we can eat moderately, and even most cancers may be avoided. Kidney calculi's disease is a stubborn disease to remind everyone how to prevent it with diet, or to slow down the growth of stones, even shrink and dissolve them and excrete them. (1) Drinking more boiled water and drinking more water will dilute urine, and the concentrations of calcium ions and oxalate will decrease, and calcium oxalate stones will not be formed. Studies have shown that increasing urine output by 50% can reduce the incidence of kidney calculi by 86%. (2) Reasonable calcium supplementation, especially dietary calcium supplementation. Patients in kidney calculi often "talk about calcium discoloration" and mistakenly think that calcium is the culprit in kidney calculi, but it is not. kidney calculi patients also need calcium supplementation. At present, the medical community explains from two different angles why kidney calculi patients need calcium supplementation. Firstly, calcium supplementation can combine with oxalic acid contained in vegetables in the gastrointestinal tract to form insoluble calcium oxalate, which is excreted with feces, reducing part of oxalic acid absorbed by the gastrointestinal tract and excreted by the kidney, thus reducing the probability of kidney calculi. The second is the "theory of acid-base balance" put forward by Japanese scholars. That is, when the blood is acidic, stones are easy to form. When alkaline, inhibit the formation of stones. When calcium is deficient, the blood is acidic, calcium is supplemented reasonably, and the blood is alkaline, which is beneficial to inhibit the formation of stones. (3) Limit the intake of sugar. A recent study by American scientists shows that the intake of high-sugar foods can increase the chance of kidney calculi's disease. Therefore, we should pay attention to eating less sweets. (4) Eat less foods with high oxalate content. Foods with high oxalate content include tomatoes, spinach, strawberries, beets and chocolates. Excessive oxalate intake is also one of the main reasons for kidney calculi. (5) Eat less soy products. Soy foods are high in oxalate and phosphate, and can fuse with calcium in the kidney to form stones. (6) Drink milk carefully before going to bed. People who have a bad sleep, drinking milk before going to bed will help them sleep. However, after sleep, urine volume decreases and concentrates, and various tangible substances in urine increase. 2~3 hours after drinking milk, it is the peak of calcium excretion through the kidney. Calcium suddenly increases through the kidney in a short time, which is easy to form stones. Therefore, kidney calculi patients should not drink milk with high calcium content before going to bed. (7) Don't take too much cod liver oil. Cod liver oil is rich in vitamin D, which has the function of promoting the absorption of calcium and phosphorus by intestinal membrane, and suddenly increasing the excretion of calcium and phosphorus in urine will inevitably lead to precipitation and easy formation of stones. (8) Eat more black fungus. Black fungus is rich in various minerals and trace elements, which can have a strong chemical reaction on various stones, so that stones can be stripped, differentiated, dissolved and excreted.
