Scientists found that an antioxidant in cocoa can prevent weight gain and help lower blood sugar levels.
The researchers say there is also evidence to suggest eating dark chocolate can improve thinking, decrease appetite and lower blood pressure.
The latest study, published in the Journal of Agricultural and Food Chemistry, revealed that an antioxidant in cocoa can prevent mice from gaining weight and that it also lowered their blood sugar levels.
Dr Andrew Neilson and his colleagues explained this is because cocoa, the basic ingredient of chocolate, is one of the most flavanol-rich foods available.
This is good because antioxidants – of which flavanols are one type – have been shown to help fight weight gain and Type 2 diabetes.
