Antioxidants are important substances that help protect our cells from harm caused by free radicals. Free radicals are unstable molecules that can cause stress in the body, which may lead to serious diseases like heart disease, cancer, and diabetes.
Eating foods high in antioxidants can help strengthen your body’s defenses and improve your general health and longevity. Here are 5 great foods that are high in antioxidants:
