Flavonoids
Flavonoids
Flavonoids (/flaˈvɒnɔɪdz/) are a diverse group of phytonutrients (plant chemicals) found in almost all fruits and vegetables. They are known for their beneficial effects on human health, including their antioxidant, anti-inflammatory, and anti-cancer properties.
Etymology
The term "flavonoid" is derived from the Latin word "flavus," meaning yellow, which refers to the color of many flavonoid compounds.
Types of Flavonoids
Flavonoids can be classified into several subgroups, including:
- Flavonols: These are found in a wide variety of fruits and vegetables, including onions, kale, and broccoli.
- Flavanones: These are found in citrus fruits.
- Flavones: These are found in parsley and celery.
- Isoflavones: These are found in soy and soy products.
- Anthocyanidins: These are found in berries and other red/blue/purple fruits and vegetables.
- Flavan-3-ols: These are found in green tea, chocolate, and grapes.
Health Benefits
Flavonoids have been studied for their potential health benefits, which include:
- Antioxidant properties: Flavonoids can neutralize harmful free radicals in the body, reducing oxidative stress and potentially preventing diseases like cancer and heart disease.
- Anti-inflammatory effects: Flavonoids may help reduce inflammation in the body, which can help prevent or manage conditions like arthritis and asthma.
- Cardiovascular health: Some studies suggest that flavonoids may help improve heart health by reducing blood pressure, improving blood flow, and reducing inflammation in the blood vessels.
- Cancer prevention: Some flavonoids have been shown to inhibit the growth of cancer cells and reduce the risk of certain types of cancer.
