Flavonoids – Found in tea, apples, berries, onions and dark chocolate

Phenolic acids – Common in coffee, whole grains, and certain fruits

Lignans and stilbenes – Present in seeds, whole grains, and some vegetables
Consuming a variety of plant-based foods rich in polyphenols is advised because each type of polyphenol has unique health benefits.
