Fralin Biomedical Research Institute at VTC scientist identifies a connection in the brain between stress and emotional eating
If you’ve had a near miss accident in your car or suffered the intimidation of a menacing person, you’ve probably felt it — a psychological reaction to a threat called a fight or flight response. Your heart rate climbs, anxiety washes over you, you might shake or sweat. But hours after that stress passes, you may feel another response — a powerful desire for comfort food, that highly processed, high-fat stuff you know isn’t good for you. It can relieve stress and tension and provide a sense of control. Emotional eating following a stress-triggering interaction is familiar to many of us, and to scientists as well. Now, Sora Shin, assistant professor at the Fralin Biomedical Research Institute at VTC, and her research team have pinpointed a molecule found in a region of the brain called the hypothalamus that is connected to changes in the brain that lead to emotional overeating.
