Polyphenols−Defined

Polyphenols are natural, antioxidant-rich compounds found abundantly in plant-based foods like fruits, vegetables, coffee, tea, and herbs. There are over 8,000 known types, categorized into four main groups: flavonoids, phenolic acids, polyphenolic amides, and stilbenes/lignans.

Along with protecting plants against environmental challenges, one of the main roles of polyphenols is powerful antioxidant activity, enabling them to protect cells from damage caused by free radicals, and to reduce oxidative stress. Additionally, they support healthy blood sugar control, lower blood pressure, enhanced brain health, and improved digestion.

As one study noted, to be properly absorbed, polyphenols go through gut microbial metabolism to form bio accessible metabolites. These have been shown to offer protection from cardiovascular, cancer, oxidative stress, inflammatory, and bacterial diseases. Consuming a diverse, colorful, plant-rich diet is the best way to ensure high polyphenol intake.
