Abstract

Trends of food intake per capita per day and digestive cancer mortalities in Japan since World War II are discussed with special reference to switching points in these. Data were obtained from the National Nutri­tion Survey and Vital Statistics during the period from 1950 to 1983. Annual changes demonstrate the features of marked increases in animal food consumption and intestinal cancer mortality and gradual decrease in rice consumption and stomach cancer mortality. The relationships between food intake and digestive cancer mortalities were consistent with previous findings by other investigators, although green and yellow vegetable con­sumption showed no significant results. Switching points of the time series in food intake and digestive cancer mortalities were calculated using the maximal likelihood estimating procedure, and were obtained in about the middle of the 1960’s. The time lag from the switching points for food intake to those for mortalities was less than that expected.
