We've been asking our Twitter followers to tweet us some questions about chocolate or chocri in general, and we keep getting pretty interesting queries. Today's question relates to chocolate's beneficial health-related effects, and comes from our Twitter friend @sharlyn_lauby who wants to know: Is it true that chocolate improves your short-term memory?

chocolate improves your short-term memoryThe notion that chocolate boosts short-term cognitive function seems to be rooted in a UK study from a few years back. Interestingly, it seems that not only does chocolate have a positive effect on short-term memory, but that it seems to last for a few hours:

"A study led by Professor Ian Macdonald found that consumption of a cocoa drink rich in flavanols - a key ingredient of dark chocolate - boosts blood flow to key areas of the brain for two to three hours. ...The findings, unveiled at one of the biggest scientific conferences in America, also raise the prospect of ingredients in chocolate being used to treat vascular impairment, including dementia and strokes, and thus for maintaining cardiovascular health.

We've talked about the studies that link chocolate and cardiovascular health on our blog before, but it's interesting to see how those processes affect the brain, too. And while we won't say you need a chocolate bar to get through your SATs, we'll be the the first to say it certainly can't hurt.

There you have it- have you got a chocolate related question? Let us know in the comments!
