"Cardiovascular improvements
Dark chocolate provides two major benefits to your cardiovascular system: it helps to lower blood pressure, and it reduces cholesterol. For those who are at risk of heart disease, a study from 2012 found that daily consumption of the food was a cost-effective way to lower the chances of having a cardiac event, by reducing total cholesterol, LDL cholesterol and lowering blood pressure (all are factors that are important to be well-controlled when having a kidney disease).. Another randomized controlled trial that investigated the impact of eating dark chocolate on the cardiovascular system of end-stage kidney disease patients on dialysis has reported a significant improvement of vascular function by 53% in acute settings . While in chronic use, this improvement was sustained at 18%, with reduction of diastolic blood pressure and increase in heart rate after consumption of coco supplements for 30 days, the study reported that the Impressive degree of endothelial dysfunction reversion is comparable with the effects observed after administration of statins in patients with end-stage kidney disease."
