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.
