For those of us who love nibbling on chocolate but feel guilty afterwards, this could be the news we've been waiting for.
Scientists claim they have developed a type that is so healthy it could be taken as medicine.
The key ingredient in chocolate, cacao, contains antioxidants and minerals, and can even help lower blood pressure while increasing "good" cholesterol.
But these health benefits are outweighed by the fact most chocolate bars are at least 70 per cent fat and sugar.
Now, an American company has developed a prototype that is only 35 per cent sugar and fat, by sweetening the unpalatable pure cacao with a herb from the Andean region of Bolivia and Peru.
