Knowra Nutritional epidemiology Nutritional epidemiology Nutritional epidemiology studies how foods, nutrients, and dietary patterns relate to health and disease across populations. It combines dietary assessment with epidemiological methods to identify associations and evaluate evidence.
Dietary assessment : The collection of information about foods, drinks, nutrients, or eating patterns consumed by individuals. Methods such as recalls and food records determine which dietary exposures an analysis can estimate.
Dietary pattern : The combinations and quantities of foods and beverages that characterize a person's diet. Pattern-based analyses capture mixtures of foods that nutrient-by-nutrient analyses may miss.
Diet and cardiovascular disease : Research on how foods, nutrients, and dietary patterns relate to heart and blood-vessel diseases. Cardiovascular outcomes are a major focus of population-based diet research.
Nutritional science : The study of how nutrients and foods affect organisms, health, and biological processes. It includes controlled and mechanistic research beyond population-level associations.
Dietary biomarker : A measurable biological indicator that provides information about food or nutrient intake. Biomarkers may validate reported intake, but many foods lack specific, reliable indicators.
Food frequency questionnaire : A questionnaire that asks how often a person usually consumes listed foods over a specified period. Its low cost enables large studies, but memory and portion-size errors can distort intake estimates.
Cohort study : An observational study that follows a group over time to compare outcomes across exposures. Prospective cohorts can relate reported diets to diseases that develop years later.
Diet and cancer : Research examining associations between dietary exposures and cancer incidence, progression, or mortality. Long latency and complex causes make study design and interpretation especially demanding.
Clinical nutrition : The use of nutrition assessment and care to prevent or treat health conditions in individuals. Its focus on individual diagnosis and treatment differs from population-level risk estimation.
Ultra-processed food : An industrially formulated food category defined by processing-based classification systems such as NOVA. Studies test its health associations, while classification and causal interpretation remain contested.
