Ringkasan	The Mediterranean Diet Adherence Screener is a 14-item food frequency questionnaire designed to rapidly assess adherence to the Mediterranean dietary pattern. Developed by Schröder and colleagues in 2011 and validated in the PREDIMED randomized controlled trial, it is one of the most widely used tools for measuring Mediterranean diet compliance in research and clinical practice. The MEDAS is particularly valuable for epidemiological studies, intervention trials, and cardiovascular disease prevention programs.	The Food Frequency Questionnaire is a self-administered dietary assessment tool designed to measure habitual food and nutrient intake over an extended period (typically 6–12 months). Developed by epidemiologists, particularly Walter Willett at Harvard, the FFQ has become a cornerstone of nutritional epidemiology research, enabling large-scale studies to assess dietary patterns and examine diet-disease relationships. FFQs vary in length (50–200+ items) and focus, but all share the purpose of estimating average dietary intake in a time-efficient manner suitable for population studies.
