What Are Polyphenols?
Definition and Significance
Polyphenols are a diverse group of phytochemicals characterized by the presence of multiple phenol units. They are found in fruits, vegetables, nuts, seeds, tea, coffee, red wine, and chocolate. These compounds contribute to the vibrant colors, flavors, and aromas of many plant foods.
Types of Polyphenols
Polyphenols are classified into several categories:
- Flavonoids: The largest group, including quercetin, catechins, and anthocyanins.
- Phenolic acids: Such as chlorogenic acid and gallic acid.
- Polyphenolic amides: Including avenanthramides in oats.
- Other polyphenols: Resveratrol, curcumin, and stilbenes.
Understanding these types helps in identifying foods rich in specific polyphenols for targeted health benefits.
