Polyphenol: Natural Compounds Powering Health and Well-Being
Polyphenols are a large, diverse group of naturally occurring organic compounds characterized by the presence of multiple phenol structural units. They are abundantly produced by plants as secondary metabolites, primarily serving to protect them from ultraviolet radiation, pathogens, and oxidative damage. This broad category encompasses several well-known subclasses, including flavonoids (found in berries, tea, and cocoa), phenolic acids (in coffee, whole grains, and berries), stilbenes (such as resveratrol in red wine), and lignans (in flaxseeds and sesame seeds). It is this widespread presence in the plant kingdom that makes them an integral part of the human diet, contributing to the color, bitterness, astringency, and aroma of many fruits, vegetables, and beverages.
The significant interest in polyphenols stems from their potent antioxidant and anti-inflammatory properties, which are linked to a range of potential health benefits. Upon consumption, these compounds help neutralize harmful free radicals in the body, reducing oxidative stress—a key…
