What is it: polyphenols?


Polyphenols are a diverse group of natural compounds found in many plant foods, such as fruits, vegetables, nuts, seeds, and grains. They are characterized by their chemical structure, which includes several phenol units.

Polyphenols have been shown to have a wide range of biological activities and health benefits, including antioxidant, anti-inflammatory, anti-cancer, heart-protecting, nerve-protecting, and anti-diabetic effects. Some of the best-known polyphenols include flavonoids (e.g., quercetin, catechins, anthocyanins), phenolic acids (e.g., caffeic acid, ferulic acid), and stilbenes (e.g., resveratrol).

The health benefits of polyphenols are considered primarily due to their antioxidant properties, allowing them to scavenge harmful free radicals and protect cells from oxidative damage. In addition, polyphenols may interact with different cellular pathways and regulate gene expression, leading to a variety of physiological effects.

Overall, polyphenols are an important component of a healthy diet and have been linked to a reduced risk of chronic diseases such as cardiovascular disease, cancer, and neurodegenerative diseases.
