Several studies have been conducted to evaluate the effects quercetin from onions has on the body. Further research at the Agricultural University of Wageningen showed that daily consumption of onions may result in increased accumulation of quercetin in the blood. Studies at Wageningen Agricultural University, the Netherlands, showed that the absorption of quercetin from onions is twice that from tea and more than three times that from apples.īased on studies conducted at The Queen’s University at Belfast, Ireland and Wageningen Agricultural University, the content of quercetin in onions is estimated to be between 22.40 mg and 51.82 mg per medium-sized onion (100 grams).

Studies have indicated that quercetin helps to eliminate free radicals in the body, to inhibit low-density lipoprotein oxidation (an important reaction in the atherosclerosis and coronary heart disease), to protect and regenerate vitamin E (a powerful antioxidant), and to inactivate the harmful effects of chelate metal ions. Onions contain organosulfur compounds that may offer unique health benefits.Īntioxidants are compounds that help delay or slow the oxidative damage to cells and tissue of the body.Onions contain quercetin, a flavonoid (one category of antioxidant compounds).Onions are low in sodium and contain no fat.They also contain calcium, iron, and have a high protein quality (ratio of mg amino acid/gram protein).High in Vitamin C, onions are a good source of dietary fiber, and folic acid.
“Onions may be among the vegetables that will be prized not only for their addition to our cuisine, but for their value-added health characteristics,” said Irwin Goldman, Associate Professor of Horticulture, University of Wisconsin-Madison. Plenty of onion health research provides strong evidence of its nutritional value. Onions not only provide flavor, they also provide important nutrients and health-promoting phytochemicals.
