Flavonoids are a class of plant compounds with potent antioxidant properties. They are found in many plant-based foods and drinks, offering protection against oxidative stress and inflammation. Oxidative stress occurs when free radicals outnumber antioxidants in the body, leading to cellular damage and contributing to the development of chronic diseases. Flavonoids help counter this damage, supporting overall health.
Flavonoids are categorised into six main groups:
- Flavonols (e.g., quercetin found in apples, onions, and tea)
- Flavones (e.g., apigenin in parsley and celery)
- Isoflavones (e.g., genistein in soy products)
- Anthocyanins (e.g., in berries and red cabbage)
- Flavan-3-ols (e.g., catechins in green tea)
- Chalcones (e.g., in hops and other plants)
