In 2006, researchers from the Experimental & Clinical Cardiology journal studied the effects of wine and resveratrol on heart disease. Wine drinkers have higher lipoprotein (HDL) levels, which protect the heart and arteries.

Red wine also increases NO production. NO, or endothelial nitric oxide synthase, dwindles during the early stages of diabetes, hypertension, and heart failure. The polyphenols in red wine tell the body to produce more NO, which not only guards the heart but also increases oxygen production and metabolism.
