What are the Challenges in Assessing Dietary Quality?
Assessing dietary quality presents several challenges. Self-reported dietary data, typically collected through food frequency questionnaires or 24-hour dietary recalls, can be subject to recall bias and inaccuracies. Additionally, dietary patterns are complex and influenced by cultural, socioeconomic, and environmental factors, which can complicate the analysis and interpretation of data. To mitigate these challenges, epidemiologists often use multiple dietary assessment methods and statistical techniques to validate and cross-check data.
