Can Chocolate Make You Smarter?

BrainCraft Imagine you could ask a bunch of Nobel Prize winner one question: What is the secret to you intelligence? They answer: Chocolate. It sounds crazy but it is not far from the truth as you might think. Last year a study found a significant correlation between chocolate consumption per capita and the number of Nobel laureates from various countries. The linear correlation was surprisingly strong. All countries fall nicely around the trend line except Alfred Nobel's homeland Sweden, which has far more Nobel winner per capita given chocolate consumption. We all love to believe that chocolate can boost our intelligence. Well...Can it? There is something super inside chocolate, dark chocolate not milk chocolate and that is flavanol, a potent antioxidant. So far flavanols have been shown to lower blood pressure a little by improving the function of inner lining blood vessel so it's easier for blood to flow through them. Flavanols have also been effective to slow down or even reversing the reduction in memory and think skills that occur with aging. In one study, elderly participants were given two cups of flavanol rich or flavanol poor cocoa to drink everyday. Well...neither of the flavanol rich or poor cocoa led down to any overall effects on patients cognitive abilities. Except for those who already had compromised blood flow white matter damage to their brains. These people found that blood flow in their brains improved by 8% and the time it took to complete a working memory test went down from 167 to 116 seconds. Since chocolate only boosted blood flow to the brain and memory skills in those with impairments, the benefits aren't quite applicable to a large healthy population. But watch these space, there are still lots of studies being done looking into possible benefits of chocolate consumption. Some funded by big confectionary companies. And there is still this correlation between chocolate consumption of a country and their number of Nobel laureates. Of course the correlation does not imply causation. It indicates that either a country's chocolate consumption influences the number of Nobel prizes won, the number of Nobel prizes won influences chocolate a country's consumption, or both chocolate and prizes are influenced by a common factors. If you are craving flavanols, chocolate isn't the only or best way to get them. The amount of flavanols in dark chocolate varies a lot depending on the type of cocoa bean, where is it from and how is it manufactured. Sometimes flavanols are even removed from chocolate because of their bitter taste. Tea, grapes and apples are other rich sources of flavanols. Chocolate is like other things...a sometimes food.
