Onions help lower cholesterol levels in the body and may help dissolve blood clots, reducing the risk of heart disease and stroke. Furthermore, onion is one of the richest plant-based sources of quercetin, a plant compound with many health benefits. Onion contains organic sulfur compounds, which give it its characteristic pungent taste and strong aroma. To maximize the benefits of sulfur compounds, onion should be eaten raw rather than cooked, according to the health-focused website Webmd. Improving cholesterol: studies indicate that eating onions can lower bad cholesterol (LDL) and improve blood lipid levels, which is beneficial in managing lipid disorders. Lowering blood pressure: the antioxidant flavonoid quercetin, found in onions, helps lower high blood pressure, thereby reducing the risk of cardiovascular disease. Reducing inflammation and plaque buildup: the anti-inflammatory properties in onions help reduce inflammation in blood vessels, preventing atherosclerosis. Preventing blood clots: the organic sulfur compounds in onions act as natural anticoagulants, preventing blood clots that can lead to heart attacks and strokes. Therefore, regular and continuous consumption of onion allows quercetin to accumulate in the bloodstream, providing maximum long-term antioxidant benefits. All types of onions contain these health-promoting compounds, contributing to meals rich in nutrients beneficial for heart health. Despite the many benefits of onions, they should be considered part of a healthy and balanced diet, not a substitute for prescribed blood pressure or cholesterol medications. The average person consumes about 9 kilograms of onions per year, eating them raw, cooked, pickled, or powdered. Onion is rich in compounds that help protect the heart, reduce the risk of certain types of cancer, and facilitate insulin production in the body.
