What you eat and drink isn’t the only thing that determines whether you’ll get kidney stones but it sure does play a big part. And if diet changes might help prevent kidney stones -- passing a stone is said to be one of the most painful experiences ever -- then it’s worth considering these seven tips:
1. Drink plenty of water and other fluids. It’s first on the list for a reason -- Water dilutes urine and flushes away mineral-like materials that could possibly form kidney stones.
2. Coffee and tea are fine if they help increase your fluid intake. Beer and alcohol are OK, too, in moderation. But avoid dark colas and grapefruit juice if you are prone to kidney stones.
3. Keep track of sodium and keep it under the U.S. recommended daily allowance (RDA) of 2,400 mg. Check labels on processed foods.
