Hunger Hormone May Protect Against Stress Induced Depression And Anxiety

By doing tests on mice fed on a calorie restricted diet, US researchers have discovered that ghrelin, a hormone that increases when people don't eat, may defend against symptoms of depression or anxiety brought on by stress. The research is the work of scientists led by senior author Dr Jeffrey Zigman, assistant professor of internal medicine and psychiatry at the University of Texas (UT) Southwestern Medical Center in Dallas.
