You’ll find it hard to find someone who doesn’t love a bit of chocolate. It is estimated that approximately 1 billion people eat it everyday, and the average European consumes 15 pounds of it every year! The reason for such admiration stems around a key chemical. Chocolate contains phenylethylamine, which releases certain ‘pleasure’ endorphins in the brain that make us feel good all over. While chocolate is often regarded as a ‘guilty pleasure’, though, the 28th October is a time you can fill your face without the worry. This is because it’s one of the days that celebrates National Chocolate Day.
