Nutritional Epidemiology: Investigating Diet and Disease Relationships
Nutritional epidemiology is the study of the relationship between diet and disease. It is a branch of epidemiology that investigates how food and nutrient intake affect the risk of developing chronic diseases such as heart disease, stroke, type 2 diabetes, and cancer. Nutritional epidemiologists use a variety of methods to study these relationships, including observational studies, clinical trials, and laboratory experiments.
