A Food Frequency Questionnaire (FFQ) is a dietary assessment tool that asks people how often they eat specific foods and beverages over a set period, such as the past month or year. It’s commonly used in nutrition research to estimate usual dietary patterns in large groups. FFQs are efficient and cost-effective, but they rely on memory and may not accurately capture portion sizes or all culturally specific foods.
