title: Influence on the selenium concentration and selenium intake of infants of infants of ingredients in Spanish homogenised infant beikosts.
abstract: Selenium (Se) concentration in 13 homogenised beikosts ("any additional food used in infant nutrition different from human milk and formulas") was investigated, as well as the influence of ingredients on Se concentration in three beikost types (meat, vegetables and fish). Levels of Se varied widely, ranging from 20 micrograms/kg d.w. for mixed vegetables to 258 micrograms/kg d.w. for hake with rice. These values increased as high-protein ingredients (meat or fish) were included. Fish-based beikosts showed the highest contribution of Se, covering more than 50% of the RDA in the USA for infants from 6 to 12 months old. The best Se sources were meat and fish, and their contributions to Se concentrations in the final products were 85.3% for chicken with rice and 75% for hake and vegetables.
