Thesis title: Memory-Based Dietary Assessment Methods: Reliability and Influencing Factors

Thesis outline: Accurate dietary assessment is fundamental for investigating the intricate relationship between nutrition and health, informing public health recommendations, and estimating exposure to potential dietary contaminants. Among the commonly used tools, the 24-hour dietary recall is prevalent in large-scale epidemiological studies. However, as a memory-based, self-reported method, it is subject to inherent limitations, particularly memory bias and underreporting, which threaten the validity of nutritional data.

My doctoral project addresses the reliability of 24-hour dietary recall methods and the factors influencing recall accuracy. Specifically, the study aims to quantify discrepancies between recalled and actual intake using an objective reference. This research seeks to identify key moderators of recall performance and provide recommendations for improving the validity of dietary intake data in research settings.
