Measuring Healthy Diets: The Past, Present and Future of Dietary Assessment

Dear Colleagues,

Dietary assessment is a cornerstone of nutritional research, providing valuable insights into the association between diet and health. Over the years, methods that measure dietary intake have greatly advanced, from conventional food frequency questionnaires and 24-hour recalls to more advanced digital tools and biomarkers. These advancements reflect efforts to improve the accuracy, reliability and feasibility of collecting dietary intake data. Recent innovations leverage mobile applications, wearable devices and machine learning algorithms, providing new opportunities for more accurate and objective dietary data collection.

Despite these developments, challenges persist in accurately assessing the quality of diets and aligning metrics with the evolving concepts of healthy diets. There is a need to develop standardized indicators that reflect global dietary recommendations and ensure consistency across different populations.

This Special Issue will explore the evolution of dietary assessment methodologies, highlighting recent advances and future directions for measuring healthy diets.
