What Methods are Used in Nutritional Epidemiology?
Several methods are employed to assess dietary intake and its association with health outcomes:
1. Dietary Surveys: These include 24-hour recalls, food frequency questionnaires (FFQs), and food diaries. 2. Biomarkers: Biological samples like blood or urine can provide objective measures of nutrient intake or nutritional status. 3. Epidemiological Studies: These include cross-sectional studies, cohort studies, and case-control studies to investigate the associations between diet and diseases.
