Dark chocolate, which has been shown in several studies to improve artery flexibility, may also help people with peripheral artery disease (PAD) walk a little better, researchers found.
PAD patients with symptoms of intermittent claudication who ate dark -- but not milk -- chocolate experienced improved walking autonomy, researcher Lorenzo Loffredo, MD, of Rome's Sapienza University, and colleagues, wrote online in the Journal of the American Heart Association.
Impact on Walking Performance Was Modest
The study was small, with just 20 participants. And the effect was modest, with the dark chocolate consumers showing an 11% increase in maximal walking distance compared with no change in patients who ate equal amounts of milk chocolate.
Loffredo and colleagues called the research a "proof-of-concept" study, adding that bigger studies with longer follow-up times are needed to confirm the findings.
Natalie Evans, MD, of the Cleveland Clinic, who was not involved with the study, said further research is warranted.
