When cancer patients visit Lindsay Malone, RD, at Cleveland Clinic, they often tell her they’ve cut out coffee because they assume it’s unhealthy. Coffee, however, is on the list of cancer-fighting foods published by the American Institute for Cancer Research because of its high antioxidant content. “Cancer starts with DNA damage,” says Malone. “The antioxidants in coffee protect your cells and keep them healthy. If you have any DNA damage from, say, secondhand smoke or environmental pollutants, antioxidants can help repair cell damage.” Various studies have linked coffee to decreased risk of liver, breast, prostate, and melanoma skin cancers, among others.
