Free radicals are dangerous molecules that can accumulate in your body and cause serious health problems, like cancer. According to the National Cancer Institute, free radicals are formed with incomplete electron shells, which makes them more chemically reactive and damaging to your health. Toxic chemicals from substances like cigarette smoke and environmental radiation can also cause free radicals. Eating foods with antioxidants help prevent, neutralize and eradicate free radicals before they have a chance to cause DNA damage and long-term health problems.
