Summary

Daily chromium intake in Belgium was assessed using duplicate food portions and atomic absorption spectrometry. The average intake is 53 micrograms/day, aligning with other countries and near the lower limit of recommended levels.

Area of Science:

  • Nutritional Science
  • Analytical Chemistry
  • Public Health

Background:

  • Chromium is an essential trace element vital for carbohydrate and lipid metabolism.
  • Dietary intake assessments are crucial for understanding nutritional status and potential deficiencies.
  • Previous international chromium intake data provide a comparative baseline.

Purpose of the Study:

  • To determine the average daily dietary chromium intake among the Belgian population.
  • To compare Belgian chromium intake levels with international data and recommended dietary allowances.

Main Methods:

  • Duplicate portions of food consumed daily were collected from a representative sample.
  • Food samples were subjected to microwave-assisted acid digestion for sample preparation.

  • Chromium concentration was quantified using atomic absorption spectrometry (AAS).

    • Main Results:

    • The mean daily dietary chromium intake in Belgium was determined to be 53 ± 31 micrograms per day.
    • This intake level is comparable to those reported in most other countries.
    • The calculated intake falls within the lower range of safe and adequate daily dietary intake recommendations.

    Conclusions:

    • Dietary chromium intake in Belgium appears adequate but is at the lower end of the recommended spectrum.
    • The findings suggest a need for continued monitoring of chromium intake and its health implications.
    • The analytical methodology employed provides a reliable method for future dietary mineral assessments.
