摘要	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 Food Neophobia Scale is a 10-item self-report instrument measuring the degree to which individuals are reluctant or fearful of trying new foods. Developed by Pliner and Hobden in 1992, the FNS measures food neophobia—an aversion to unfamiliar foods—which is influenced by both evolutionary factors (caution toward unknown foods) and learned behaviors. The scale is widely used in nutrition, food science, and psychology research examining dietary diversity, food acceptance, and barriers to healthy eating.
