To prevent calcium stones, it's crucial not to exceed daily calcium intake. Excessive calcium in urine is a major risk for stone formation.

Eating too much salt increases the risk of kidney stones. People with kidney stones should limit salt to 2300 mg per day.

Foods rich in oxalate such as spinach, chocolate, sweet potatoes, and nuts are a big risk for kidney stones, thus consume in limitation.

Eat calcium and oxalate-rich foods together during meals. This helps them bind in the stomach, reducing the risk of stone formation in kidneys.
