Why do people say that chocolate can help when you're sad or depressed?

I'm not sure too but choc doesnt really lifts my spirit much neither do ice-creams. Maybe if you like sweet food, you would be happy. But for neutruals like me, it's pretty much useless

Even ice cream will do, because when you're depressed you want to eat more but mostly chocolate because it gives you a feeling of satisfaction..

On a personal note, that is not a myth. On my part, it's true. I'm actually eating cadbury right now. Been craving for chocolates since i got depressed over my failed relationship happened just months ago.... Believe me, that's true! (",) .. i don't know what's with chocolates, i'm just craving for it always.
