Estimation of Dietary Intake of Selenium by Female Adults Using the Duplicate Portion Method

Abstract

The selenium content of 26 meals taken by three female adults living in Maki town, Niigata Prefecture, was determined by hydride-generation atomic absorption spectrophotometry. The selenium content of the samples was 23.8±9.9 μg, and the daily dietary intake was estimated to be 68.7±21.8μg (mean±SD). There was a significant correlation between selenium and animal protein content (r=0.668, p<0.001). Rice was not a major source of selenium.
