Abstract
Daily intakes of nitrate and nitrite of middle-aged men (30-59 years of age, n = 100) in Hiroshima Prefecture were estimated directly by the duplicate portion method. The daily intake of nitrate was 190.8 +/- 128.5 mg. The daily intake of nitrate/kg body weight was 2.87 +/- 2.00 mg, which is about 78% of the acceptable daily intake (ADI). The daily intake of nitrate tended to increase with increasing age. The daily intake of nitrite was 3.837 +/- 3.647 mg. The daily intake of nitrite/kg body weight was 0.057 +/- 0.050 mg, which is about 95% of the ADI. In the case of nitrite, there was no age-related difference. The proportions of men, whose daily intakes of nitrate and nitrite were above the ADI, were 27% and 34%, respectively. The proportion of men above the ADI of both nitrate and nitrite was 10%.
