New research suggests that eating junk food may actually make your mood worse. There are times when a bar of chocolate seems like the only solution for a bad mood. But new research suggests that eating junk food may actually make your mood worse.

Researchers at Penn State University claim that women who are concerned about their diet and image experience a worsening of their mood after eating something unhealthy.

So why do we do this?? a recent article in Discovery Heatth & Fitness explains it this way:

Why can't we resist comfort foods? Their lure has both chemical and emotional triggers. "Some foods work on serotonin levels in the brain to produce a calming effect," Diekman says. "Adjusting your blood sugar levels by not being hungry can relax you."

"Stress ... triggers a drop in serotonin and leads to a craving for sweets and starches, which help you cope," says Latson. "Because they help improve your mood and trigger happy memories, it's a learned response to eat chocolate, cookies and cake when under stress simply because we associate them with a sense of security."
