Dr. Allison Sylvetsky, Associate Professor of Exercise and Nutrition Sciences at George Washington University, studies how sugar substitutes and artificial sweeteners affect diet, metabolism, and long-term health.

In this episode, Dr. Sylvetsky discusses what current research reveals about artificial sweeteners and how they may be shaping our diets in ways we don’t always realize.
