Researchers are certainly trying to find out what, if anything is the secret to the benefits claimed for cocoa (or cacao) to our health. This paper looks at some studies done so far and concludes that, as discussed in my latest book Better Brain Food, there do seem to be some benefits from eating this delicious food. What they are talking about is the sort of dark chocolate with at least 70% cocoa, or cocoa powder itself - that's not as sweet as everyday chocolate and more concentrated than what most people eat.
It seems that cocoa does more than supply helpful antioxidants, it also helps change a few things that happen in the brain (one being assisting efficient blood flow) - and its the combination of those which is thought to be of help.
Of course there is more to brain health than eating chocolate, but this is encouraging research for sure!
