Lyn Steffen is a Professor in the Division of Epidemiology & Community Health at the University of Minnesota School of Public Health. She holds dual membership in the Center on Aging (COA) and the Healthy Weight Research Center, reflecting her interdisciplinary research focus spanning nutritional epidemiology and cardiovascular disease.
Her educational background includes:
- PhD in Epidemiology from the University of Texas Health Science Center, Houston
- MPH in Public Health Nutrition from the University of Minnesota
- BA in Home Economics and Sociology from the University of Minnesota
Dr. Steffen's research focuses on nutritional epidemiology with particular emphasis on dietary patterns, biomarkers, and cardiovascular disease outcomes across the lifespan. She has conducted extensive studies on dietary intake (including diet patterns, added sugar, and processed foods), biomarkers (metabolomics, fatty acids), adipose tissue depots, and their relationships with cardiovascular disease. Her expertise spans aging, nutrition epidemiology, cardiovascular disease epidemiology, diet assessment, diet patterns, nutrition in older adults, dietary intake and health, and fatty acids & CVD. Her work frequently employs large cohort studies and sophisticated analytical approaches to understand how dietary components influence health outcomes.
Analysis of her publication record reveals a consistent trajectory of high-impact research in nutritional epidemiology, with recent emphasis on metabolomic approaches to dietary assessment, omega-3 and omega-6 fatty acids, plant-based diets, and their relationships with cardiovascular disease, kidney disease, and metabolic health. Her work often involves international collaborations and pooled analyses across multiple cohorts, demonstrating methodological sophistication and clinical relevance.
Dr. Steffen maintains an active research program with numerous publications in top-tier journals including European Heart Journal, Circulation, Lancet Public Health, and BMJ. Her work contributes significantly to evidence-based dietary guidelines and public health recommendations for preventing chronic diseases through nutritional interventions.
