Jacob Teitelbaum, MD shares results of a study showing that eating either dark chocolate or a sugar-free cocoa drink was found to improve heart blood vessel function and lower blood pressure.
In a placebo-controlled study in 45 overweight adults, eating either dark chocolate or a sugar-free cocoa drink was found to improve heart blood vessel function and lower blood pressure. Interestingly, improvements in endothelial function were significantly greater with the sugar-free cocoa drink as compared to the sugar-containing cocoa drink. Blood pressure dropped with dark chocolate (systolic: -3.2 mm Hg, diastolic: -1.4) and sugar-free cocoa (systolic: -2.1 mm Hg; diastolic: -1.3 mm Hg). The authors conclude, “Further investigation is clearly warranted to determine longer term effects of habitual solid and liquid cocoa ingestion, optimal dosing of chocolate for cardiovascular benefit, variation in beneficial effects among diverse populations, and, ultimately, the influence of dietary cocoa intake on cardiac events.”
