Delicious news: Your sweet tooth could help those with an artery disease

Capture

Dark chocolate may be able to help patients who have peripheral artery disease.

Peripheral artery disease causes patients to have trouble walking and exercising because the blood flow to their limbs is impaired.

In a new study, researchers in Spain had twenty patients with this condition eat either dark chocolate or milk chocolate.

They found those who had dark chocolate were able to walk 11% farther than those who had milk chocolate.

They also experienced an increase in blood flow.

Experts say dark chocolate is stacked with polyphenols, which help the blood vessels to dilate.
