Diet for Kidney stone Urolithiasis or renal stones are deposits of acidic salts and minerals, which are seen in the interior of the kidneys. They are small and hard and are diluted in the urine. Concentrated urine results in crystallization of the minerals, thereby resulting in stone formation. Pain in the back, abdomen and groin are common. Research reveals the positive association between animal proteins and certain kinds of stones. Calcium or calcium oxalate stones are seen due to increased intake of sodium, animal proteins and sugars.
Whole grains, fruits and vegetables are recommended, whereas peanuts, cocoa, spinach tea and coffee are avoided. Spinach contains oxalates, which bind with calcium to form calcium oxalate stones. Processed meats, tinned soups, snack foods, condiments, stock cubes and sauces are better avoided, due to their increased sodium content. Red meat, offal meats, tinned fish, meat extracts and mussels are rich in purine, which in turn increases the uric acid concentration.
Calcium crystallization increases. Protein in the diet also raises stone formation or renal calculi. Egg, fish and chicken are reduced in the diet. Lemon juice and olive oil mixture is not medically proven for renal stones. Visit a nephrologist for further guidance.
