9 Foods to Fight Off Free Radicals

Oxidative stress can occur in our bodies when oxygen molecules split apart resulting in unpaired electrons. These lone electrons are otherwise known as free radicals. This occurrence can damage DNA, proteins, and cells, and has been associated with many diseases. Various factors have been linked to a buildup of free radicals, including air pollutants, tobacco, alcohol, and junk foods. Some foods fight against free radicals, particularly those that are high in antioxidants. To keep yourself and your family healthy, be sure to include plenty of these foods in your diet.
