Abstract
To examine possible reduction in dietary cadmium (Cd) intake, 24-h duplicates of diet were collected twice in the same village in north-eastern Japan, once in 1976–1977 (71 samples) and then in 1989 (198 samples) and analyzed for Cd contents. The statistical analysis by sex and age decade showed that there has been a significant ( P < 0.01–0.05, depending on sex and age) reduction in Cd intake during this 12-year period. The intake by men at 30–59 years was 28.8 μg/day (as a geometric mean of 41 samples) in 1976–1977 and 20.8 μg/day in 1989, indicating some 28% reduction, whereas the value for women of the same age range was 24.9 μg/day in 1976–1977 and 15.7 μg/day in 1989, with a reduction by 37%. A similar reduction in Cd contents was observed in cooked rice samples collected in 1980 and 1990 in the vicinity of the study field. Probable reasons for the improvement are discussed.
