What to Know about Flavonoids

You may have heard of the buzzword ‘antioxidants’ and how they are beneficial to our bodies. However, ‘flavonoids’ (pronounced as fla-vuh-noydz), is the key word and dietary component to remember when it comes to tea! Flavonoids are naturally occurring dietary components found in a variety of plant-based foods and beverages such as tea, cocoa, fruits and vegetables, that are responsible for the color and flavor in tea, and have been associated with heart health benefits.1,2,3,4

Flavan-3-ols are a sub-group of flavonoids and in fact, tea is one of the top sources of flavonoids in the diet.
