Dietary History and Dietary Records in Renal Stone Patients and Controls

Abstract

Dietary factors have been suggested to be important in the increase in renal calcium stone disease in Western countries. It has been shown that dietary animal protein is the nutrient best related to the frequency of stone disease between various countries¹. Animal protein has also been shown to cause an increased excretion of urinary constituents important for calcium stone formation²⁻⁶. In another controlled study on dietary habits, however, based on interviews with stone formers and controls, no difference could be found regarding the major nutrients, except for a higher intake of fibre among healthy controls⁷. These conflicting reports prompted us to make the present study.
