Benefits of Radicchio
Radicchio is a Healthy Treat
Radicchio has several health properties that can give children and adults a healthy boost, from high levels of antioxidants, to dietary fiber, and an array of vitamins and minerals. One little serving (approximately 86 grams or 12 leaves) of radicchio has 11 % of your daily total dietary fiber and 10% of your daily recommended dosage of Vitamin C.
