What Are Flavonoids?

Why flavonoids are good for you, 

and what foods you'll find them in

Benefits of Flavonoids
Flavonoids are plant-based compounds with powerful antioxidant properties, which means they reduce inflammation, promote healthy arteries, and help fight aging by preventing - and repairing - cellular damage. Flavonoids may also protect against dementia, Alzheimer’s disease, and some cancers.

Recommended Amount: How Much You Need
Get your fill of flavonoids by eating plenty of fresh fruit and vegetables every day -- we recommend four servings of fruit and five servings of veggies. Tea, red wine, and dark chocolate also contain flavonoids, but that’s not a green light to overindulge. Limit wine to a glass a day for women, two for men; and limit chocolate to a couple of small squares - about an ounce.

Good Sources of Flavonoids
There are many types of flavonoids, and their concentration in specific foods varies greatly, depending on how a product is grown and processed. So use the list below as a general guideline for foods that tend to be rich in flavonoids. Eating a diverse diet that regularly includes some of the following foods will provide you with a healthy helping of flavonoids:

Apples (flavonoids are in the skin)
Blueberries
Broccoli

Capers
Chocolate (dark, not milk) and cocoa
