WALTM,It seems logical to put a person with kidney stones on a low calcium diet, but that actually encourages more stone formation. As calcium levels drop, oxalate levels rise, and high oxalate concentration in the urine promotes stone formation. Sometimes doctors tell their patients to avoid foods like chocolate, nuts beets, rhubarb, spinach strawberries and wheat bran the foods that are high in oxalates.Drinking water is important for sltone prevention just sip water throughout the day.Linda
