Cocoa not only tastes good, it also makes you clever. The secondary plant substances contained therein are responsible for this.

Your brain is what you eat – this or a similar one could simply summarize the results of a British-US American team. The psychologist Professor Dr. Gabriele Gratton from the Beckman Institute for Advanced Science and Technology at the University of Illinois at Urbana-Champaign and his colleagues examined 18 healthy young men in a multi-stage test. They left this on two separate occasions Cocoa drink. Once it was a simple chocolate drink, and once it was also included Flavanolen enriched. Flavanols, phytochemicals, are also found in grapes, apples, berries and other foods.
Before and after drinking, the researchers examined how strongly the brain responded to one Hypercapnia responded. To do this, the study participants had to briefly inhale air with a high proportion of CO2 (approx. 5%). After that, as expected, blood (and thus oxygen) flowed into the brain more intensely. This effect was particularly pronounced when the men previously had flavanolreichen Cocoa had been drinking. After consuming the fortified drink, the men also cut cognitive tests better off. Especially with more difficult and complex tasks, they were clearly superior in terms of accuracy and speed.
