Mazy's Muddle: Chocolates for the brain!

 According to a research paper read out at the British Psychological Society, mental arithmetic became easier after volunteers had been given large amounts of compounds found in chocolate, called flavanols, in a hot cocoa drink. One also feels less tired while this flavanol goes into one’s mouth. The flavanols, part of a group of chemicals called polyphenols, work by increasing the flow of blood into the brain.

For the study 30 volunteers were asked to count backwards in groups of three from a random number between 800 and 999 generated by a computer.  My question is, if 30 volunteers had to be given 50mg of flavanol in a cup of drinking chocolate, what would be the total grams of flavanol consumed by them? Go ahead, eat a piece of chocolate and answer this one. But be sure to brush your teeth later. Research says bacteria gnaw away chocolatey teeth at an amazing speed of...oh I’ve forgotten! I should eat more almonds to aid my memory. Pssst, the same study also says that fruits and vegetables have a lot of flavanols.  

Out of the maze

1.5 gram.  30 x 50 = 1500mg. Since 1000mg = 1g,  the 30 would have taken volunteers 1.5 g of flavanol together.
