Preventing kidney stones can be achieved by simple adjustments in your diet. Take these steps to maintain kidney health and minimize the risk of developing painful kidney stones:
Limit Oxalate-Rich Foods
Oxalate binds with calcium to form kidney stones. Foods high in oxalates include spinach, chocolate, sweet potatoes, coffee, and peanuts. Simultaneous consumption of high-oxalate and calcium-rich foods can prevent stone formation.
Hydration is the key
Inadequate water intake leads to concentrated urine, increasing the likelihood of stone formation. Lemonade and orange juice, containing citrate, are also beneficial. Aim for about eight glasses of fluids daily or enough to produce two liters of urine. Adjust this based on factors like exercise, sweating, or a history of cystine stones.
Avoid High Doses of Vitamin C Supplements:
Supplements elevate the risk of stones, particularly in men. Vitamin C from food sources, does not pose the same risk.
Calcium-Rich Foods
Contrary to common belief, low-calcium diets may elevate the risk of calcium oxalate stones and osteoporosis. Choose calcium-rich foods like low-fat milk, cheese, and yogurt. Be cautious with calcium supplements, and consider taking them with meals to mitigate the risk of stone formation.
Reduce Sodium
High salt intake increases the risk of calcium kidney stones by preventing calcium reabsorption. Lowering salt intake helps maintain lower urine calcium levels, reducing the risk of kidney stone development. Carefully read food labels to minimize sodium-rich foods.
Herbal Remedies:
Chanca Piedra, the “stone breaker,” is a popular herbal remedy for kidney stones, believed to prevent stones and reduce existing stone size. Exercise caution with herbal remedies, as they lack rigorous regulation and research.
Moderate Animal Protein Intake:
Animal protein consumption increases urine acid, leading to uric acid and calcium oxalate kidney stones. Consider limiting or avoiding beef, poultry, fish, and pork.
