1. Limit High-Sodium Foods
Reduce packaged snacks, pickles, instant noodles, processed meats and heavily salted foods. Excess sodium can increase calcium in the urine.
2. Watch High-Oxalate Foods
People with calcium oxalate stones may need to limit very high-oxalate foods such as spinach, rhubarb, beetroot and some nuts, depending on their urine results.
3. Reduce Excess Animal Protein
Large amounts of red meat and other animal protein may increase the risk of certain stones, particularly uric acid stones.
4. Avoid Excessive High-Purine Foods
Organ meats, sardines and anchovies are high in purines and may need to be limited by people prone to uric acid stones.
5. Stay Away From Excess Sugary Drinks
Choose water instead of frequently drinking sugar-sweetened soft drinks and other heavily sweetened beverages.
What Should You Eat?
A kidney-stone-friendly diet can include water, fresh fruits and vegetables, adequate dietary calcium, moderate protein and low-sodium foods.
Remember, calcium should not be unnecessarily eliminated from the diet. Adequate dietary calcium can help reduce oxalate absorption.
Bottom Line
The best foods to avoid with kidney stones depend on your stone type and individual risk factors. If stones keep coming back, consult a urologist for appropriate evaluation and personalized dietary advice.
