    Flavonoids are found in food in things like teas and dark-colored berries. They're similar to vitamins and are important in maintaining health. Studies have suggested an association between diets high in flavonoids and a reduced risk of cancer and heart disease. They're what gives a lot of foods we have color. They're particularly effective at helping the body get rid of toxins that affect us.

    Flavonoids are substances that are like vitamins but, unlike vitamins, aren't essential for life. We don't know the mechanism of action of flavonoids, but they are powerful antioxidants, even more powerful than vitamins C and E combined. Flavonoids also have anti-inflammatory effects. However, it may well be effects other than antioxidant or anti-inflammatory effects that produce the benefit of flavonoids in keeping our immune system young.

    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.
  • AMichael T. Murray, Naturopathic Medicine, answered

    The flavonoids are a group of plant pigments, which exert antioxidant activity that is more potent and effective against a broader range of oxidants than the traditional antioxidant nutrients vitamins C and E, beta-carotene, selenium, and zinc. Besides lending color to fruits and flowers, flavonoids are responsible for many of the medicinal properties of foods, juices, herbs, and bee pollen. Flavonoids are sometimes called "nature's biological response modifiers" because of their anti-inflammatory, anti-allergic, antiviral, and anticancer properties.

    Flavonoids are the components responsible for the color of fruits and vegetables; they have been found to be important for our health. Although they have not reached "star" recognition yet, consumers are starting to hear more about them.

    Many studies are showing flavonoids to have versatile health benefits. For instance, they may prevent heart diseases and some types of cancers. Some of the key flavonoids are flavonols, isoflavones and catechins. Foods rich in flavonoids are green tea, spices, soy and fruits such as: oranges, pink grapefruit, blueberries, red and purple grapes.

    Flavonoids are a category of protective chemicals in plant foods called phytochemicals. They include resveratrol, hesperidin, anthocyanin, quercetin, and tangeritin act. All of these act against inflammation and prevent platelets from sticking together. They also block the enzymes that raise blood pressure.

    Sources include vitamin-C-rich foods such as apples, cherries, blueberries, grapefruit, oranges, plums, limes, strawberries, broccoli, pears, red grapes, kale, onions, and kiwifruit.
