When theobromine is devoured in form of large chocolate bar do not cause electrophysiologic or acute hemodynamic cardiac changes in young and healthy adults. In healthy men, theobromine pharmacokinetics were similar when measured after 14 days of abstention from methylanthines and after one week of ingesting dark chocolate. The study results could not be extrapolated to patients having any diseases of conditions or effects of consuming chronic chocolate.

  1. Vascular and Endothelial function

Dark chocolate promoted a rapid and meaningful improvement of platelet and endothelial function in healthy smokers 2 to 8 hours after consumption. The smokers displayed increase in atherogenic potential as they have platelet and endothelial dysfunction being related with increasing chances of cardiovascular problems. Findings are related to antioxidant effect of dark chocolate rich in polyphenols. Excess body weight and hypertension are essential risk factors for endothelial function.
