Summary
Daily manganese intake in Belgium was assessed. The average intake was 3.1 mg/day, which is comparable to other countries and falls within recommended ranges.
Area of Science:
- Nutritional Science
- Public Health
- Analytical Chemistry
Background:
- Manganese is an essential trace element crucial for various physiological functions.
- Dietary intake assessments are vital for understanding population nutritional status and potential deficiencies or excesses.
- International comparisons of manganese intake help contextualize national dietary patterns.
Purpose of the Study:
- To evaluate the daily dietary manganese intake among the Belgian population.
- To compare the obtained manganese intake values with established international recommendations and data from other countries.
Main Methods:
- Utilized duplicate portion sampling to accurately capture daily dietary intake.
- Employed microwave oven destruction for sample preparation prior to analysis.
- Quantified manganese levels using atomic absorption spectrometry (AAS).
Main Results:
- The mean daily dietary manganese intake in Belgium was determined to be 3.1 ± 1.1 mg/day.
- This average intake level is consistent with findings reported for most other countries globally.
- The measured intake falls within the recommended dietary allowance (RDA) ranges set by organizations like the World Health Organization (WHO) and the National Research Council (USA).
Conclusions:
- Dietary manganese intake in Belgium appears adequate and aligns with international nutritional guidelines.
- The findings suggest no immediate public health concern regarding manganese undernutrition or overconsumption in the Belgian population based on current dietary habits.
