🔬 Basic Definition
Flavonoids are plant-based antioxidants that help protect cells from damage, reduce inflammation, and support overall health.
🌿 Where They’re Found
You can find flavonoids in:
- Fruits (e.g., apples, berries, oranges, grapes)
- Vegetables (e.g., onions, kale, broccoli)
- Herbs and spices (e.g., parsley, thyme)
- Beverages (e.g., tea, red wine, cocoa)
- Legumes and soy products
💪 Key Health Benefits
- Antioxidant – Neutralize harmful free radicals
- Anti-inflammatory – Help reduce chronic inflammation
- Heart health – Improve circulation, reduce blood pressure
- Brain health – May protect against cognitive decline
- Cancer protection – Some types may help inhibit tumor growth
- Immune support – Strengthen the body’s natural defenses
🔬 How They Work
Flavonoids interact with enzymes and receptors in the body, influencing processes like:
- Detoxification
- Cell signaling
- Gene expression
Flavonoids are a diverse group of plant compounds classified into six main subtypes, each with unique chemical structures and health benefits. Here are the primary types of flavonoids:
1. Flavonols
- Common examples: Quercetin, Kaempferol, Myricetin
- Foods: Onions, kale, broccoli, apples, berries, grapes, tea
- Benefits: Antioxidant, anti-inflammatory, supports heart and brain health
2. Flavones
- Common examples: Apigenin, Luteolin
- Foods: Parsley, celery, chamomile, peppers
- Benefits: Anti-inflammatory, anti-cancer, supports skin and nervous system health
3. Flavanones
- Common examples: Hesperidin, Naringenin, Eriodictyol
- Foods: Citrus fruits (oranges, lemons, grapefruits)
- Benefits: Cardiovascular protection, antioxidant, cholesterol-lowering
4. Flavan-3-ols (also called Catechins)
- Common examples: Catechin, Epicatechin, EGCG (Epigallocatechin gallate)
- Foods: Green tea, black tea, cocoa, dark chocolate, apples
- Benefits: Heart health, brain protection, anti-inflammatory, improves blood flow
5. Anthocyanidins
- Common examples: Cyanidin, Delphinidin, Malvidin
- Foods: Berries (blueberries, blackberries, raspberries), red cabbage, grapes, cherries
- Benefits: Antioxidant, anti-inflammatory, supports vision and cardiovascular health
6. Isoflavones
- Common examples: Genistein, Daidzein
- Foods: Soybeans, tofu, soy milk, legumes
- Benefits: Estrogen-like effects, bone health, may reduce menopause symptoms
