Need to do something important this afternoon? Don’t take any chances—eat chocolate first.
According to researchers from Northern Arizona University, brain scans show dark chocolate boosts attention and alertness so you perform better.
In a study published in the journal NeuroRegulation researchers used electroencephalography, or EEG technology to take brain images of 122 undergraduate students. Brain activity was measured before eating chocolate, then five minutes and 60 minutes after eating chocolate.
