(FOX) - The antioxidants contained in dark chocolate may help people suffering from reduced blood flow in their legs.

A pilot study that appears in the journal of the American Heart Association involved 20 people in their 60s and 70s who suffered from peripheral artery disease (PAD).

Patients walked a treadmill in the morning and again two hours after 40 grams of dark or milk chocolate.

Results show patients walked farther and longer after eating the dark chocolate than they did after the milk chocolate.

Investigators also found levels of nitric oxide, a gas linked to improved blood flow, were higher after eating dark chocolate.

This suggests the higher levels may be responsible for widening restricted arteries and improving the patient's ability to walk.

However, study authors warn this is not a license to eat chocolate as the sugar and fat could contribute to obesity.
