Summary

Daily copper intake in Belgium was assessed using duplicate portion sampling and atomic absorption spectrometry. The average intake of 1.5 mg/day is comparable to other nations but falls at the lower limit of recommended dietary levels.

Area of Science:

  • Nutritional Science
  • Analytical Chemistry

Background:

  • Copper is an essential trace element vital for numerous physiological processes.
  • Dietary intake assessments are crucial for public health and nutritional guidance.

Purpose of the Study:

  • To evaluate the daily dietary copper intake among the Belgian population.
  • To compare Belgian copper intake levels with international recommendations.

Main Methods:

  • Utilized duplicate portion sampling to collect representative dietary samples.
  • Employed microwave oven heating for sample preparation.
  • Determined copper concentration using atomic absorption spectrometry (AAS).

Main Results:

  • The mean daily dietary copper intake in Belgium was determined to be 1.5 ± 0.4 mg/day.

  • This intake level is comparable to those reported in many other countries.
  • The measured intake is at the lower end of the safe and adequate daily dietary intake range.

    • Conclusions:

    • Belgian dietary copper intake is within the range observed globally.
    • Current intake levels may warrant attention to ensure they remain adequate for long-term health.
    • Further monitoring of copper intake is recommended to ensure public health nutritional status.
