Kidney Stones and Diet
For years, doctors thought that a low-calcium diet was the best way to prevent kidney stones, especially for those who already had the condition. However, several studies have shown that low-calcium diets are not effective, and may actually be harmful, since they tend to increase the likelihood of low bone density and osteoporosis.
Recent studies have shown that a diet with normal amounts of calcium is needed to prevent kidney stones. Over a period of five years, scientists studied a group of men with recurrent kidney stones, and found that those who had normal calcium levels in their diet were less likely to form new stones than men who were on a low-calcium diet. Calcium is important because it binds to oxalate and removes it from the body. Researchers are continuing to study the benefits of this diet.
