[Description]:
Quercetin is the most abundant of the flavonoids. Quercetin belongs to the flavonoids family and consist of 3 rings and 5 hydroxyl groups. Querctin is also a building block for other flavonoids. Quercetin occurs in food as a aglycone (attached to a sugar molecule). Only a small percentage of the ingested quercetin will get absorbed in the blood.
[Nutritional Value]:
Quercetin is found in many common foods including apple, tea, onion, nuts, berries, cauliflower and cabbage.
[Action of Quercetin:].
Quercetin has many health promoting effects, including improvement of cardiovascular health, reducing risk for cancer. Quercetin has anti-inflammatory and anti-allergic effects. All these activities are caused by the strong antioxidant action of quercetin. It will help to combat free radicals molecules, which can damage cells.
As many other flavonoids, quercetin prevents the oxidation of LDL (bad) cholesterol.
The anti-inflammatory action of quercetin is caused by the inhibition of enzymes, such as lipoxygenase, and the inhibition of inflammatory mediators. Quercetin also inhibits the release of histamine, which causes congestion, by basophils and mast cells.
Studies have shown that quercetin reduces the cancer risk of prostate, ovary, breast, gastric and colon cells.
Quercetin also seems to reduce the production of uric acid, by inhibiting the xanthine oxidase, thereby easing gout symptoms.
Studies have shown an improved lung function and lower risk of certain respiratory diseases (asthma and bronchitis) for people with high apple (rich in quercetin) intake.
