Resum	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.	The Mini Nutritional Assessment is a simple, rapid, and non-invasive screening tool designed to identify malnutrition and nutritional risk in older adults. Developed by Guigoz, Vellas, and colleagues in 1994, it combines subjective assessment with objective anthropometric and laboratory measurements. It is widely used in clinical practice, research, and community settings to detect nutritional decline and guide intervention.
