Onions are a versatile vegetable that make it easy to add extra goodness to your meals. They contain a unique combination of plant compounds called flavonoids, which have antioxidant and anti-inflammatory benefits. In particular, onions are one of the richest food sources of flavonoids, specifically quercetin.
What is quercetin?
Quercetin is a powerful antioxidant that is found in plant foods, including fruit and vegetables. It has been shown to help promote a healthy heart and brain as well as reduce the risk of certain lifestyle diseases. Onions are particularly rich in quercetin – 100g of onion contains 59mg of quercetin (average of onion varieties).
