Your Arteries Need This: Dark Chocolate's Power to Restore Vascular Health

For the smoker, this antioxidant action is particularly crucial for reducing platelet activation. Smoking makes platelets, the small cell fragments responsible for clotting, "sticky" and prone to aggregation, a key step in forming the dangerous blood clots that cause heart attacks and strokes. Research has demonstrated that dark chocolate consumption can inhibit this process by lowering oxidative stress specifically in smokers, essentially making their blood less likely to clot inappropriately. By mitigating the free radical damage that promotes this pro-clotting state, the flavanols provide a buffer against one of smoking's most immediate and life-threatening cardiovascular risks, which can be exacerbated in a sedentary person whose overall circulation is already sluggish.
