Nicola McKeown, PhD: Principal Investigator

Dr. NicolaNM McKeown is an Associate Professor and Director of 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.
