Dr. Sylvetsky's research focuses on the consumption and health effects of sugar-sweetened beverages and low-calorie (artificial) sweeteners, throughout the life course 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
• examining effects of low-calorie sweetener restriction on cardiometabolic health in youth with type 1 diabetes
• 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 pathways
• understanding multifactorial determinants of low-calorie sweetener and sugar-sweetened beverage consumption
• behavioral interventions to lower sugar-sweetened beverage consumption among children and adolescents
• examining consumers' perceptions of low-calorie sweeteners and how a front-of-package label for low-calorie sweeteners impacts their perceptions and selections of food and beverage products
• investigating effects of low-calorie sweetener consumption during pregnancy and lactation on maternal and infant health

Dr. Sylvetsky 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.
