Bio

Dr. Sylvetsky is an Assistant Professor in the Department of Exercise and Nutrition Sciences and is Director of the Bachelor of Science in Nutrition Science undergraduate degree program. She is also affiliated faculty at the Sumner M. Redstone Global Center for Prevention and Wellness and is a Special Volunteer at the National Institute for Diabetes, Digestive, and Kidney Diseases (NIDDK) in the Intramural Research Program of the National Institutes of Health (NIH).

Dr. Sylvetsky joined the GW faculty in 2014, prior to which, she was a post-doctoral fellow in the Diabetes, Endocrinology, and Obesity Branch of NIDDK in the Intramural Research Program of the National Institutes of Health (NIH). She received a doctorate in Nutrition and Health Science from Emory University.

Dr. Sylvetsky's research focuses broadly on obesity and diabetes in youth. Her primary research interests are in studying the consumption and health effects of sugar-sweetened beverages and low-calorie (artificial) sweeteners. She is also interested in the role of dietary exposures in childhood on future weight and metabolic health.

Research

Research:

Dr. Sylvetsky's research focuses on the consumption and health effects of added sugars and low-calorie (artificial) sweeteners, with an emphasis on their consumption during childhood.

These projects have included:

studying consumption of low-calorie sweeteners in various populations, as well as dietary and metabolic correlates of their cosumption
investigating alterations in glucose, insulin, and satiety hormones after ingestion of low-calorie sweeteners
assessing the time course of low-calorie sweetener entry into human breast milk, urine, and plasma
evaluating effects of low-calorie sweeteners on the human gut microbiome
studying whether prolonged ingestion of diet soda containing sucralose and acesulfame-potassium impairs metabolic signaling pathway
understanding multifactorial determinants of low-calorie sweetener and sugar-sweetened beverage consumption
behavioral interventions to lower sugar-sweetened beverage consumption among children and adolescents

Beyond consumption and health effects of low-calorie sweeteners and sugar-sweetened beverages, Dr. Sylvetsky Meni's research interests also include the effects of early life exposures on diet, weight, and health; the relationship between diet and gut microbiota, behavioral, environmental, and policy approaches for improving the overall diet; and the role of dietary patterns in prevention and management of obesity and type 2 diabetes.
