Frequently Asked Questions
What is radicchio?
Radicchio (Cichorium intybus var. foliosum) is a type of Italian chicory with vibrant reddish-purple leaves and a distinctive bitter flavor. It is rich in anthocyanins, vitamin K, and unique bitter sesquiterpene lactones like lactucopicrin that support digestion, liver function, and cardiovascular health.
How much radicchio should I eat and is it safe?
One to two cups of radicchio daily is a typical recommendation. It is very safe as a food for most people. Those on blood-thinning medications like warfarin should keep their intake consistent due to its vitamin K content. People with Asteraceae plant allergies should introduce it cautiously.
Why is radicchio so bitter and does cooking help?
Radicchio's bitterness comes from lactucopicrin and other sesquiterpene lactones, which are the same compounds that stimulate bile production and support liver detoxification. Grilling, roasting, or braising significantly mellows the bitterness and brings out a subtle sweetness, while still retaining most of its anthocyanin and mineral content.
