Effects of Low Habitual Cocoa Intake on Blood Pressure and Bioactive Nitric Oxide
(...)
"Results From baseline to 18 weeks, dark chocolate intake reduced mean (SD) systolic BP by –2.9 (1.6) mm Hg (P<.001) and diastolic BP by –1.9 (1.0) mm Hg (P<.001) without changes in body weight, plasma levels of lipids, glucose, and 8-isoprostane. Hypertension prevalence declined from 86% to 68%. The BP decrease was accompanied by a sustained increase of S-nitrosoglutathione by 0.23 (0.12) nmol/L (P<.001), and a dark chocolate dose resulted in the appearance of cocoa phenols in plasma. White chocolate intake caused no changes in BP or plasma biomarkers. Conclusions Data in this relatively small sample of otherwise healthy individuals with above-optimal BP indicate that inclusion of small amounts of polyphenol-rich dark chocolate as part of a usual diet efficiently reduced BP and improved formation of vasodilative nitric oxide."
