This is your brain on chocolate
I distinctly recall making a trek through the New England snow during winter mid-terms while I was in college. As just about every student on campus crammed for exams, the school was nice enough to offer us late-night study breaks -- typically in the form of hot cocoa and some cookies in the student union. The break was a great way to decompress, but it turns out the hot cocoa actually offered its own unique benefits to the brain-clogged undergrads that we were.
Researchers at the Nottingham Medical School in England found that the flavonoids in chocolate increase blood flow to your brain for up to three hours. This is particularly beneficial during times when your brain may not be operating at its best -- like, oh I don't know, when you've been awake for almost three full days, trying your best to cram a semester's worth of learning into that short of an amount of time.
Dark chocolate contains more flavonoids than does milk chocolate. Best I can remember, the university's hot cocoa offering was made of the latter. I'll use that as my excuse for only getting a B minus on that final.
