This chapter provides an overview of nutritional epidemiology for those unfamiliar with the field. The field of nutritional epidemiology developed from an interest in the concept that aspects of diet may influence the occurrence of human disease. Although it is relatively new as a formal area of research, investigators have used basic epidemiologic methods for more than 200 years to identify numerous essential nutrients. The most serious challenge to research in nutritional epidemiology has been the development of practical methods to measure diet. Because epidemiologic studies usually involve at least several hundred and sometimes hundreds of thousands of subjects, dietary assessment methods must be not only reasonably accurate but also relatively inexpensive. Epidemiologic approaches to diet and disease and the interpretation of epidemiologic data are discussed.
