A family doctor from Scotland has called for a tax to be set on chocolate to help pay for the fight with obesity and type 2 diabetes.
The doc thinks a system should be set-up similar to cigarettes and alcohol.
Food scientist and nutritionist Dr Walker told the BBC news website: "Obesity is a mushrooming problem. We are heading the same way as the United States.
"There is an explosion of obesity and the related medical conditions, like type 2 diabetes. I see chocolate as a major player in this, and I think a tax on products containing chocolate could make a real difference."
