What are the Key Methods Used in Nutritional Epidemiology?
Nutritional epidemiologists employ various research methods, including:
1. Dietary Assessment Methods: These include food frequency questionnaires (FFQs), 24-hour dietary recalls, and food diaries to assess individuals' dietary intake. 2. Observational Studies: These studies, such as cohort studies and case-control studies, help identify associations between dietary factors and health outcomes. 3. Randomized Controlled Trials (RCTs): These are considered the gold standard for establishing causality between dietary interventions and health outcomes.
