Onions have long been a popular ingredient in the kitchen. They can be used in a variety of ways and add flavor and depth to many different dishes. Besides boosting the flavor profile of your favorite foods, onions also have nutritional value. Onions are considered to be one of the best vegetables for your overall health. The next time you cook with onion or order an onion-studded dish, you can feel great about yourself in that you are receiving a number of benefits that you maybe didn’t even know about.
11. Heart Health
Onions contain many compounds that are believed to help lower the incidence of heart disease. The allyl disulfide and allium found in onions release nitric oxide, which can decrease the stiffness of blood vessels. This can inhibit clot formation and reduce blood pressure, which decreases stroke, peripheral vascular disease, and coronary artery disease risks.
Onions also contain sulfur, which can help lower triglyceride and cholesterol levels, and are considered to help prevent clot formation. Although all forms of onions can be beneficial, eating them raw may have even higher value.
10. Ulcer Prevention
Onions are rich in flavonoids, which have been shown to help prevent gastric ulcers. Flavonoids fight off free radicals and prevent the growth of Helicobacter pylori, which is an ulcer-forming microorganism. It is estimated that around 20 percent of the United States population over the age of 40 have this microorganism in their digestive tract. Although most of these individuals will not develop ulcers, eating onions will help lower the risk even more.
