A new study calls into question the effectiveness of comfort foods in improving peoples' moods.
Researchers at the University of Minnesota say gorging on ice cream, pizza, and other types of comfort foods do not work.
Those foods are no better for improving a person's mood than eating other types of foods, like a carrot stick, or eating nothing at all.
Researchers believe the findings could help people trying to lose weight or eat more healthy.
The study is published in the journal Healthy Psychology.
