Chicory is a family of bitter greens, but its most well-known member is radicchio, the small red or purple leaf that comes in a head about the size of a softball. It’s one of the best dietary sources of polyphenols—powerful micronutrients that serve a role in preventing disease. A study in the Journal of Nutrition found that people who consume 650 mg a day of polyphenols have a 30 percent chance at living longer than those who consume less than that. A cup of chicory leaves clocks in at about 235 mg (double that of spinach!), so consider adding a little leafy red into your leafy greens.
