Kidney Stones

14.     Uric stones occur in patients who have an increased uric acid in the blood and increased uric acid excretion in the urine. Since uric acid is an end product of purine (nitrogenous compound) metabolism, foods with a high purine content should be avoided. Purine-rich and acidic foods to be avoided include non-vegetarian foods such as red meat, chicken, organ meats like that of kidneys/liver/ brain, eggs, alcohol including beer, soft cola drinks, all canned, refined, processed and fried foods, white flour (maida), bread and sugar.

 

15.     Purine-rich and acidic foods to be consumed in moderation by uric stone-prone patients include grains, legumes, lentils especially chick peas, urad dal, barley, corn, rice, beans, oatmeal, tomatoes, peas, cauliflower, aubergines, mushrooms, lady finger, asparagus, spinach, bananas, guavas, pomegranate, milk products like curd and cheese, tea/coffee especially with sugar, chocolates, nuts except almonds, cakes and confectionary.

Nutritional Blockbusters that fight Kidney Stones

17.     The blockbusters include the following: –

 

(i)      Water – One of the most effective ways of preventing kidney stones is to drink at least 2½ -3 litres of water/fluids (more if you exercise and in hot weather) daily. Water helps to keep the urine diluted and washes out potential stone-causing particles from the body. Water also prevents calcium, oxalates, phosphates and uric acid from turning into crystals. Water helps to drain out the sludge and small stones and keeps the ph of urine under control.

(ii)     Calcium – Because most kidney stones contain calcium, doctors once recommended eating fewer dairy products and other dietary sources of calcium. Recent studies found that the people with the highest intake of dietary calcium are actually less likely to develop kidney stones. When you eat high-calcium foods with high oxalate foods, the calcium keeps your body from absorbing the oxalate.
