Due to the different composition of kidney calculi in each patient with nephropathy, the methods of diet therapy will be different, as follows: 1. Patients with calcium oxalate stones and calcium phosphate stones: 1. Drink plenty of water, not less than 3000ml per day, to facilitate the discharge of small stones. 2. Because urine is mostly alkaline, Chinese medicine practitioners should eat more foods that synthesize acidic urine, such as chicken, duck, fish, meat and other meat foods, eggs, fat and so on. At the same time, acid phosphate, ammonium chloride and other drugs can be taken to acidify urine and promote the dissolution of stones. 3. Reduce alkaline foods such as vegetables and fruits. 4. Eat more foods rich in vitamins A and B. When the supply of vitamin A is insufficient, the urinary mucosa will be deformed and keratinized, and epithelial cells will fall off. If crystals are deposited on it, stones will form. 5. Calcium oxalate stones should be on a diet with low oxalic acid and low calcium, and high calcium foods such as milk, bean products, snails and shrimps, as well as water chestnut, amaranth, spinach, green garlic and onion with high oxalic acid content should be avoided. Second, patients with uric acid stones: Uric acid is mostly acidic, so patients with kidney disease should eat more alkaline foods such as vegetables, fruits and milk. And adopt a low purine diet to reduce the production of uric acid.
