food frequency method

The food frequency method is a way to assess an individual's typical diet over a period, usually months or a year. It involves asking how often a person eats specific foods or food groups, such as daily, weekly, or monthly. This information helps researchers understand eating patterns and nutrient intake without needing detailed daily logs. It's useful for large studies because it's quicker than keeping a food diary, and it provides insight into habitual consumption, which can be important for studying diet-related health outcomes.
