They are a diverse group of phytonutrients plant chemicals found in almost all fruits and vegetables along with carotenoids they are responsible for the vivid colors in fruits and vegetables Flavonoids are a diverse group of phytonutrients plant chemicals found in almost all fruits and vegetables along with carotenoids.
some other well known flavonoids include compounds such as the pcos or procyanidolic oligomers also called proanthocyanidins the pigment class of anthocyanosides the polyphenols and the genistein class of compounds the class of flavonoids called pcos are very plentiful in the bark of pine trees and in the grape seed extracts as well as red wine the pine bark extracts are available in the form of pycnogenol the class of pigment anthocyanosides is common in the herb bilberry as well as some other herbs cocoa powder in a heart on a grey background photo credit natashaphoto istock getty images flavonoids polyphenolic compounds found in plants have antioxidant powers that may provide important health benefits diets rich in flavonoids have been associated with reduced risk of a variety of diseases flavonols this widely distributed subgroup of flavonoids includes quercetin and kaempferol they are found in onions leeks brussels sprouts kale broccoli tea berries beans and apples quercetin is an antihistamine associated with helping to relieve hay fever and hives some of the best known flavonoids are quercetin and kaempferol in recent years scientists have turned to various flavonoids to explain some of the health benefits associated with diets rich in fruits and vegetables according to the linus pauling institute flavonoids are natural polyphenolic molecules common to most flowering plants both flowers and foliage flavonoids are ubiquitous in nature and are categorized according to chemical structure into flavonols flavones flavanones isoflavones catechins anthocyanidins and chalcones as a class of compounds flavonoids have been referred to as nature s biological response modifiers because of their ability to modify the body s reaction to other compounds such as allergens viruses and carcinogenic properties definition of flavonoid any of a group of oxygen containing aromatic antioxidant compounds that includes many common pigments as the anthocyanins and flavones  flavonoids are a group of plant metabolites thought to provide health benefits through cell signalling pathways and antioxidant effects these molecules are found in a variety of fruits and vegetables flavonoids are polyphenolic molecules containing 15 carbon atoms and are soluble in water the abundance of flavonoids coupled with their low toxicity relative to other plant compounds means they can be ingested in large quantities by animals including humans examples of foods that are rich in flavonoids include onions parsley blueberries bananas dark chocolate and red wine 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 helpful 1 person found this helpful 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 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 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 flavonoids are a diverse group of phytonutrients plant chemicals found in almost all fruits and vegetables along with carotenoids they are responsible for the vivid colors in fruits and vegetables flavonoids are the largest group of phytonutrients with more than 6000 types some of the best known flavonoids are quercetin and kaempferol in recent years scientists have turned to various flavonoids to explain some of the health benefits associated with diets rich in fruits and vegetables according to the linus pauling institute like other phytonutrients flavonoids are powerful antioxidants with anti inflammatory and immune system benefit dark chocolate is a good source of flavonoids plants produce thousands of compounds called phytochemicals that aren t nutrients but that provide health benefits flavonoids are one group of phytochemicals that have antioxidant abilities
