There may be a good reason why people tend to reach for those fatty comfort foods.

A new study finds that craving comes through gut-brain signaling.

Scientists say they have discovered that eating fat seems to make people less vulnerable to sad emotions, even if they don't know they're eating fat.

The study has implications for obesity, depression and eating disorders, but more research is needed to determine whether the findings have any value in treatment of these illnesses.

The study appears in the Journal Clinical Investigation.
