Diet has a central role in the pathogenesis of most major causes of morbidity and mortality in men and women today. Consequently, research investigating diet-disease relationships has important public health implications; however, studying food consumption and diet patterns has unique challenges. This nanocourse is focused on nutritional epidemiology, the study of dietary assessment, dietary determinants of health-related states or events in specified populations, and the public health application of this research. This nanocourse is intended for individuals who are interested in understanding the overall process of dietary assessment to public health recommendations and learning more about the use of dietary variables in their research.
Learning Objectives - Upon completion of this nanocourse, participants will be able to:
Day 1:
  • Understand the methods for assessing the dietary intake of populations and individuals

  • Describe studies on specific diet/disease relationships, analyze and interpret nutritional epidemiology literature

Day 2:
  • Gain hands-on experience in the actual collection, analysis and interpretation of dietary intake using publicly available online software

  •  Design nutritional epidemiology studies examining diet-disease relationships.
