Preventing Kidney Stones
A new study published in Clinical Journal of the American Society of Nephrology says that calcium rich foods - such as low-fat milk and yogurt-can be protective. What? Eat more calcium to prevent calcium containing stones? It seems that higher intakes of calcium are actually associated with a reduction in kidney stone risk.
Dietary calcium binds with oxalate, which is a waste product in the digestive system. The two substances crystallize and leave the body long before there is a chance to form a kidney stone.
Like so many things in the body, it is likely a number of factors that intertwine to cause a disorder. But it is always reassuring to find preventative recommendations that we know are healthy and that might prevent a number of problems. Since both hypertension and kidney stones are more prevalent in men over age 40, the DASH diet might be the answer.
