Application of instrumental neutron activation analysis to assess dietary intake of selenium in Korean adults from meat and eggs

Thirty three frequently eaten items among meat and eggs were collected and pretreated. Selenium (Se) contents in the diet samples were analyzed using an instrumental neutron activation analysis (INAA). 100 g of beef contains 12.4–50.9 μg of Se; pork, 11.2–22.6 μg; chicken, 10.2–13.7 μg and eggs, 28.6–43.0 μg. Beef innards and chicken eggs contain the highest amounts of Se. This study reveals that Se intake of Korean adults are 28.7 μg/day in men and 27.6 μg/day in women from meat and eggs, which are over 1/2 of the Korean recommended Se intake.
