A Gut Reaction: Why We Crave Sugar

A neuroscientist explains how the gut-brain connection encourages us to return to that tray of brownies

Duke professor Diego V. Bohórquez tells us why we want more sugar when we've already eaten some. Bohórquez is an assistant professor of medicine and pathology and a member of the Duke Institute for Brain Sciences. Turns out the cravings aren't just from our tastebuds, but also from sensors in our gut that send information to our brains about the content of our food.
