The role of antioxidants in health is crucial as they protect the body from oxidative stress caused by free radicals. These compounds can be found in fruits, vegetables, nuts, and whole grains. Antioxidants help reduce inflammation, lower the risk of chronic diseases like heart disease and cancer, and support overall health by boosting the immune system. Consuming a diet rich in antioxidants contributes to cellular health and may enhance longevity. The synergistic effects of different antioxidants can further improve health outcomes.
