Nicola McKeown, PhD: Principal Investigator

Dr. NicolaNM McKeown is an Associate Professor for the Nutritional Epidemiology Program at the Friedman School of Nutrition Science and Policy and a scientist at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University. She is internationally renowned for her work on the role of whole grains in promoting health. Dr. McKeown’s early work on the relationship between dietary carbohydrates and lifestyle factors in the development of insulin resistance and metabolic syndrome led to an increased focus on whole grains. She has made significant contributions to our understanding of the impact of whole grain intake on abdominal adiposity, weight gain, metabolic syndrome, and CVD risk. She was the first investigator to robustly characterize the relationship between whole grain intake and reduced visceral adiposity in a large cohort. Her work now employs both large observational datasets and controlled intervention studies to examine the effects of whole grains on blood biomarkers and gut microbiota. She is also leading an innovative new project to develop a fiber evidence map with the goal of compiling and synthesizing the current and emerging body of literature linking dietary fibers to health outcomes. She is a scientific advisor to the Whole Grains Council, serves on the editorial board of Nutrition Today, and is a fellow of the Obesity Society.  Dr. McKeown received a BS in Human Nutrition from the University of Ulster in Northern Ireland and a PhD in Nutritional Epidemiology from the University of Cambridge in England.

 

Sara Folta, PhD: Co-Investigator

SaraFoltaSara Folta’s research interests focus on public health nutrition, or the utilization of community-based strategies for improving dietary intake, physical activity, and body composition. She has particular expertise in behavioral psychology, communications, and qualitative methods. A major line of Folta’s research involves community-based interventions to improve heart health among women. A second area of research includes behavioral strategies to improve health and well-being among older adults, particularly through the development of physical activity interventions. Folta’s third line of research involves community-based interventions for obesity prevention among children. These studies, in which theory-based communications strategies were a major component, are notable for the use of the eco-social model in which multiple levels (individual-organization-community-policy) are targeted.


Alice H. Lichtenstein, D.Sc.
: Co-Investigator

Dr. Lichtenstein is the Stanley N. Gershoff Professor of Nutrition Science and Policy at the Friedman School, and Director of the Cardiovascular Nutrition Laboratory and Senior Scientist at the Jean Mayer USDA Human Nutrition Research Center on Aging, at Tufts University. She holds secondary appointments as Professor of Medicine at Tufts Medical Center, and an honorary doctoral degree from the University of Eastern Finland. Dr. Lichtenstein’s research group focuses on assessing the interplay between diet and heart disease risk factors.  Dr. Lichtenstein currently serves as an Associate Editor of the Journal of Lipid Research and Executive Editor of the Tufts Health and Nutrition Letter. She served on the 2000 Dietary Guidelines Advisory Committee and as vice-chair of the 2015 Dietary Guidelines Advisory Committee. Dr. Lichtenstein was vice-chair of the 2013 American Heart Association (AHA)/American College of Cardiology (ACC) Guideline on the Treatment of Blood Cholesterol to Reduce Atherosclerotic Cardiovascular Risk in Adults and member of the AHA/ACC Guideline on Lifestyle Management to Reduce Cardiovascular Risk. She received the 2006 Robert H. Herman Memorial Award in Clinical Nutrition from the American Society for Nutrition, 2008 Women’s Mentoring Award from the AHA, Excellence in Dietary Guidance Award from the American Public Health Association, and the David Kritchevsky Career Achievement Award in Nutrition from the American Society for Nutrition. This past year she received the Ralph Holman Lifetime Achievement Award from the American Oil Chemist Society. Dr. Lichtenstein is a member and was past-chair of the AHA Nutrition Committee and is currently a member of the Food and Nutrition Board of the National Academies of Sciences, Engineering, and Medicine.
