Onions are the only vegetable known to contain prostaglandin A. Prostaglandin A dilates blood vessels and reduces blood viscosity, thereby lowering blood pressure, increasing blood flow to coronary arteries and preventing thrombosis. Onions are rich in quercetin, which is biologically available and may help prevent the oxidation of low-density lipoprotein (LDL), providing important protection against atherosclerosis, scientists report.
