Quercetin
This is a natural antioxidant flavonoid, mainly concentrated in the skin and roots of onions. Quercetin can eliminate free radicals, inhibit inflammatory reactions, slow renal fibrosis and cell apoptosis, and inhibit xanthine oxidase. Therefore, quercetin in onions reduces uric acid production, and has a supportive effect for patients with gout kidney disease and hyperuricemia.
In addition, onions can inhibit factors related to kidney inflammation such as TNF-α, IL-6 and TGF-β1, slowing down the process of kidney fibrosis.
Supplementing 150162 mg of quercetin per day can help reduce atherosclerosis by about 34 mmHg, improve blood sugar and HbA1c index in people with type 2 diabetes, and help reduce metabolic pressure on the kidneys.
sulfur compounds
The characteristic smell when cutting onions is due to volatile sulfide compounds produced from the breakdown of sulfur-containing amino acids. These ingredients have anti-inflammatory, antibacterial and antioxidant effects, helping to slow down the process of kidney fibrosis.
