What are the Epidemiological Methods Used to Study Dietary Quality?

Epidemiologists employ various methods to study dietary quality, including cross-sectional studies, cohort studies, and randomized controlled trials.

- Cross-sectional studies provide a snapshot of dietary habits and health outcomes at a single point in time, helping to identify associations.
- Cohort studies follow groups of individuals over time to examine how changes in dietary quality impact health outcomes.
- Randomized controlled trials are considered the gold standard for establishing causality, as they can control for confounding variables and provide high-quality evidence on the effects of dietary interventions.
