Nutritional epidemiology

Nutritional epidemiology is a sub-branch of epidemiology. This field of study focuses on the distribution and determinants of diseases and other medical conditions in a population. Nutritional epidemiology studies the relationships between dietary patterns, nutrient intake and their impacts upon public health. Common methods in nutritional epidemiology include dietary surveys and cohort studies, by which statistical associations between (say) food consumption and medical conditions such as cancer or obesity are studied.
