So says a new study from Granada University's Department of Medical Physiology in Spain, which reported their findings in the new issue of Nutrition. There's already been research that says eating chocolate can reduce the risk of heart disease, and a study that linked eating chocolate to leanness in adults. But a new study discovered that regularly consuming chocolate helps teenagers stay slim, too.

Researchers looked at more than 1,400 teens from nine European countries, and measured body fat and activity levels. They found that the higher the teens' chocolate intake, the lower the level of total fat and fat around the middle the teens possessed -- regardless of other health factors (including exercise).

The lesson? Just eat the damned Dove bar. [Medical News Today]
