Intake of energy and nutrients; harmonization of Food Composition Databases

Area of Science:

• Nutrition Science
• Food Science
• Public Health

Background:

• Food composition databases (FCDBs) are vital for calculating nutrient intake from dietary consumption.
• Users often underestimate the limitations and methodological challenges associated with FCDBs.
• Variations in FCDBs arise from technical differences in food description, nutrient analysis, and recipe calculations.

Purpose of the Study:

• To highlight the importance of standardizing food composition data for accurate nutritional assessments.
• To address the methodological challenges in creating comparable FCDBs across different populations and regions.
• To introduce the development of a reference FCDB in Spain (BEDCA) adhering to European standards.

Main Methods:

• Reviewing existing literature on FCDB limitations and standardization efforts.
• Identifying sources of variability in food composition data collection and analysis.
• Documenting data values meticulously for each food component and nutrient.

Main Results:

• Global efforts since 1984 (e.g., INFOODS, EPIC, EuroFIR) aim to standardize FCDBs.
• Data for FCDBs are sourced from diverse origins, including private analysis, academia, government labs, industry, literature, and food labels.
• Proposals exist for evaluating the quality of food composition data.

Conclusions:

• Standardization of FCDBs is critical to eliminate discrepancies before comparing dietary data, especially concerning health outcomes.
• BEDCA is Spain's sole FCDB compiled and documented according to EuroFIR standards.
• Continued efforts in standardization are necessary for reliable international nutritional research.
