Kidney Stones


About 12 percent of Americans develop a kidney stone at some point in their lives. Stones usually result from the crystallization of calcium (which originally came in foods or supplements) and oxalate, a part of many plant foods. Some people have a tendency to lose excessive amounts of calcium or oxalate through their kidneys, and they have a greater likelihood of a stone.7-10 Kidney stones can also form from uric acid, which is a breakdown product of protein, or from struvite (ammoniomagnesium phosphate) or cystine.

The prevalence of kidney stones is three times higher in men than women, and is higher among Caucasians than Asians or African Americans, for reasons that are not clear. They are especially likely to strike between the ages of 40 and 60.

Nutritional steps are important in preventing stones and can also help prevent recurrences, which is important given that 30-50 percent of people diagnosed with a renal stone have a recurrence within five years.

Preventing stones is like keeping a salt crystal from forming in a glass of salty water. You can either reduce the concentration of salt or add more water. Epidemiologic studies have shown that certain parts of the diet help reduce the amount of calcium that filters into the urine. It is a simple matter to put these factors to work clinically.
