Antioxidants help prevent cellular damage by neutralizing free radicals, which are unstable molecules that can cause oxidative stress. Foods rich in antioxidants, such as fruits, vegetables, nuts, and whole grains, provide these protective compounds that help maintain cellular integrity. Regular consumption of antioxidants can lower the risk of chronic diseases, including heart disease and cancer. Implementing a diet high in antioxidant-rich foods can support the body’s defense mechanisms, promoting overall health and longevity.
