|It ain't rocket science. Chocolate = Smart. Simple.|
Perhaps this isn't that surprising since chocolate consumption has been documented to improve cognitive function. Since chocolate consumption could hypothetically improve brain power not only in individuals but also in a whole population, Dr. Messerli, from St. Luke's–Roosevelt Hospital and Columbia University in New York City, wondered whether there would be a correlation between a country's level of chocolate consumption and its population's cognitive function.
To investigate, he obtained a list of countries ranked by Nobel laureates per capita and then found data on per capita chocolate consumption in those countries. He discovered a significant linear correlation between per capita chocolate consumption and the number of Nobel laureates.
However, it can't be ruled-out that people of higher intelligence are more cognizant of the health benefits of chocolate flavanols, and therefore, consume more of it than others.
Regardless, this study does suggest that chocolate consumption enhances cognitive function, which supports the findings of previously studies.
So let's the kids go crazy over (real) chocolate tonight for Halloween...they'll ace their upcoming tests and exams.
