A recent study conducted by Virginia Polytechnic Institute and State University observed lower blood sugar levels in mice that were given dark chocolate. Cocoa, used to make chocolates, contain antioxidant properties which help in lowering blood sugar levels. The high levels of flavanoids found in Cocoa also helps to guard against Type 2 Diabetes.
Despite how good it may sound, most chocolates are made with lots of sugar and is bad for diabetes. Go for only dark chocolates with a minimum 70% cocoa content. Remember to consume dark chocolates in moderation as dark chocolates can still pile up on sugar and calories if taken without control.
