What Are the Challenges in Tracking Dietary Trends?
Despite its importance, tracking dietary trends poses several challenges:
Recall Bias: Participants may not accurately remember or report their food intake. Variability in Diets: Diets can vary widely between individuals and cultures, making it difficult to standardize data collection. Changes in Food Composition: The nutritional content of foods can change over time due to agricultural practices, food processing, and fortification. Technological Limitations: Advanced tools for dietary assessment may not be accessible or practical for large populations.
