The purpose of this study is to examine the nutritional environment affecting calcium stone disease in Japan. The following results were obtained. Renal stone disease in the late 1970s increased by about three times than that of the 1940s. Fats and oils, animal protein and calcium intake increased remarkably after the second World War and milk plus milk products, meat and animal products were increased surprisingly compared with 1950. The most ingested nutrients of calcium stone formers were not much different from the results of the National Nutritive Survey in Japan. But the ingested amount of calcium was unexpectedly small and did not reach the level of the daily nutritional requirement in Japanese (15 mmol). The ingested amount of total protein correlated with urinary calcium excretion and had the highest coefficient of determination to the urinary calcium excretion by multiple regression analysis. We have finished our research of individual dietary habits and suggest that the following individual dietary guidance is the primary treatment for the prophylaxis of renal stone disease.
