Do you like chocolate? It’s popular all over the world, but why? Scientists have been trying to discover its secrets.
The main thing is that chocolate makes us happy. This may have something to do with the 380 known chemicals found in it. The problem is that many of these chemicals appear in other types of food too. So, it’s difficult to know why the ones in chocolate make us feel good. But we aren’t all lost. Adam Drewnowski at the University of Michigan found that chocolate makes the human brain produce natural opiates, called optoids. These can stop pain and make us feel good.
