Dark chocolate lovers and chocolate makers will likely celebrate the results of a small study that indicates dark chocolate could help those suffering from artery disease.
The study, as reported in the Journal of the American Heart Association this month, reveals those dealing with artery issues in their legs walk longer and farther if their diet includes dark chocolate.

In the study, which involved 14 males and six females ages 60 to 78 years old, participants who ate dark chocolate increased their walking capability, an average of 11 percent farther and 15 percent longer.

Yet American Heart Association spokesperson Dr. Mark Creager said the results were very preliminary and that it is too early to recommend polyphenols or dark chocolate for cardiovascular health.
Attention, hein, uniquement le chocolat noir, pas le chocolat au lait !
L’article original Dark Chocolate Acutely Improves Walking Autonomy in Patients With Peripheral Artery Disease ▻http://jaha.ahajournals.org/content/3/4/e001072.full.pdf+html précise encore d’autres limitations de l’étude :
The study is also limited by its single-blinded design and the lack of a placebo group.
et indique qu’il y a encore du chemin avant d’inclure le chocolat noir dans le traitement thérapeutique.
In conclusion, the results of this study suggest that short term
administration of dark chocolate improves walking autonomy with a mechanism involving its high content of polyphenols and perhaps mediated by an oxidative stress mechanism, which ultimately leads to enhanced NO generation. Evaluation of walking distance by long-term dark chocolate administration is mandatory to assess whether
dark chocolate may be a novel approach for the treatment of IC in PAD patients.
