What are the primary bioactive components in radicchio causing its protective antioxidant effect?
Answer
Anthocyanins and Polyphenols
The vibrant, deep color of radicchio is the visual indicator of its significant antioxidant capacity. These protective compounds that help combat oxidative stress in the body are identified specifically as polyphenols. Among these polyphenols, the primary bioactive components responsible for this protective effect are the anthocyanins. Anthocyanins are pigments renowned for their health-promoting capabilities and are chemically similar to those found in other deeply colored fruits like blueberries and blackberries. By neutralizing unstable molecules known as free radicals, these agents help maintain cellular integrity throughout the body.
