Kidney stones are hard mineral deposits that form inside the kidneys when certain substances in urine become concentrated. Diet plays an important role in both prevention and recurrence. While no food can guarantee complete protection, certain dietary choices may help reduce the risk of stone formation.
Many people assume kidney stones are purely genetic or unavoidable. In reality, hydration, mineral balance, and daily eating habits significantly influence stone risk. This article explains five foods that may help lower your chances of developing kidney stones, how they work inside the body, early warning signs of stones, common myths, and when medical evaluation becomes necessary.
Kidney stones develop when urine contains high levels of minerals such as calcium, oxalate, or uric acid.
Common contributing factors include:
Not all stones are the same. The most common type is calcium oxalate stones. Uric acid stones and other types can also occur. Stone formation depends on multiple factors including diet, hydration, genetics, and metabolic health.
Citrus fruits are rich in citrate, a natural substance that may help reduce stone formation.
