Do you know how much sugar you eat?

BBC News looks at the amount of sugar found in the kind of food and drink we consume every day.

A total of 347 million people worldwide have diabetes and that figure is set to rise to more than half a billion in the next 20 years.

Do you think food companies should pay a "sin tax" for putting sugar in their products? Or is it down to the individual to make healthy choices?

The BBC World Service is hosting a live debate all about diabetes on Friday, 5 February at 13:00 GMT.

A panel of experts will be available to answer your questions live on air, send them to or via Twitter @bbcworldservice #diabetes
