What are Polyphenols?

For my past posts, I have been writing about Polyphenols. So what exactly are Polyphenols? 

 

Polyphenols are a class of phytochemicals (aka plant chemicals) naturally present in plants, including beans, fruits, nuts, and vegetables1. Unless a person is not consuming any plant food, the polyphenols have been a part of every person’s diet. 

 

The polyphenols are divided into numerous subclasses, which include:

  • Flavonoids,

  • Phenolic acids,

  • Lignans.

 

Flavonoids represent the most studied group of polyphenols. Particularly abundant flavonoids in foods are catechin (tea, fruits), cyanidin (berries), daidzein (soybean), epicatechin (cocoa), hesperidin (orange), proanthocyanidins (apple, grape, cocoa), and quercetin (onion, apples)1.

 

Now, you know what polyphenols are. But do you know they are very important for health management? Let’s visit this topic in my next post.
