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?
