Dark chocolate is good for you!

Here's a great Christmas present - scientists have discovered that eating chocolate is good for you!

A few squares of dark chocolate every day could help reduce the risk of heart disease, researchers have found.

The yummy stuff contains something called anti-oxidants that prevent the tubes pumping blood to the heart - the arteries - from narrowing.

But the Swiss team found that eating white chocolate did not have any healthy benefits!

Is chocolate your favourite thing?

The scientists made their discovery after carrying out tests on a group of 20 healthy smokers.

The men were asked not to eat foods rich in anti-oxidants - such as onions, apples and cabbage - before being fed 40g (2oz) portions of different types of chocolate.

After two hours, special scans showed that dark chocolate had "significantly improved" blood flow to the heart.
