Area of Science:

  • Human Nutrition
  • Environmental Health
  • Analytical Chemistry

Background:

  • Selenium (Se) is an essential element for human health, with both deficiency and excess intake causing adverse effects.
  • Dietary intake is the primary route of selenium exposure for the general population.
  • Establishing safe and adequate selenium intake levels is crucial for public health.

Purpose of the Study:

  • To estimate the average daily dietary intake of selenium (Se) in the Italian population.
  • To evaluate whether typical dietary selenium consumption falls within recommended nutritional ranges.
  • To assess the significance of dietary selenium intake in the context of human health.

Main Methods:

  • Analysis of complete meals from a factory canteen to represent an average Italian diet.

  • Quantification of selenium content in food samples using Inductively-coupled Plasma Atomic Emission Spectrometry (ICP-AES).
  • Calculation of weekly and daily selenium intake based on food consumption data.

    • Main Results:

    • The estimated average daily selenium intake for the Italian population was determined.
    • Results indicated that the daily selenium intake is well within the recommended range of 50-200 micrograms/day.
    • No evidence of excessive or deficient selenium exposure was found based on the analyzed diet.

    Conclusions:

    • The average Italian diet provides selenium within the safe and adequate intake levels.
    • Dietary selenium exposure in Italy, based on this study, does not pose a risk for toxicity or deficiency.
    • Monitoring dietary selenium intake remains important for ensuring optimal human health.
