1. Rich in Antioxidants

Onions are loaded with antioxidants, which are compounds that help combat oxidative stress in the body. Oxidative stress occurs when there’s an imbalance between free radicals and antioxidants, potentially leading to chronic diseases like cancer, diabetes, and heart disease.

• Quercetin, a flavonoid in onions, is a potent antioxidant that helps reduce inflammation and prevent cell damage.

• Red onions, in particular, are high in anthocyanins, another antioxidant linked to heart and brain health.

Regular consumption of onions can help neutralize harmful free radicals and reduce oxidative stress, promoting overall wellness.
