The European Food Safety Authority (EFSA) has ruled that cocoa powder and dark chocolate can help people improve blood circulation - a claim made by Barry Callebaut, the world’s largest maker of chocolate products. The Swiss group, which supplies food companies such as Nestle and Hershey with cocoa and chocolate products, said on Tuesday it had provided evidence to EFSA that eating 10 grammes of dark chocolate or its equivalent in cocoa that were high in flavanols helped blood flow.
