Here's a quote from the piece:
After being asked to peer review an article on flavanols, the substances found in tea, wine and chocolate, among other things, that seem to help slow down or even reverse the mental slowdowns of aging, he began to toy around with a silly idea: If chocolate consumption could boost a septuagenarian's brain power, might it also boost an entire country's?
One rainy afternoon, while stuck in a Katmandu hotel, Messerli got to playing around with the data. When he plugged in numbers from 23 countries, they made a neat linear plot on the page: Not only was the correlation between chocolate consumption and Nobel Prize winners very significant, but the probability that the distribution was due to chance — what researchers call the "p-value" — was tiny.
No real tests have specifically been done on chocolate making folks smarter in general, but we're sure it's in the works. For now, we're going to call those few moments a day when we unwrap those tiny chocolates our preparation for our Nobel Prize. Want to read more on the story?
