Dark chocolate may help control elevated blood pressure (BP), according to the results of a meta-analysis reported in the June 28 issue of BMC Medicine.
Flavanols found in chocolate have been shown to increase the formation of endothelial nitric oxide, which promotes vasodilation and consequently may lower blood pressure. There have, however, been conflicting results as to the real-life effects of eating chocolate. The researchers found that consumption can significantly, albeit modestly, reduce blood pressure for people with high blood pressure but not for people with normal blood pressure.
