When is Acid-Ash diet prescribed?

Kidney stone formation can be affected by the pH of urine in people who have a history of forming stones. If you've had kidney stones that contained phosphorus, a low-phosphorus diet may have been recommended, as well as a diet that produces "acid ash." Foods that produce "acid ash" include cheese as well as whole grains, meat, eggs, cranberries, Prunes and plums. Struvite stones (those that contain the compound called magnesium ammonium phosphate) also call for a diet low in phosphorous and one that produces an acid ash.
