Antioxidants play a vital role in a healthy diet by neutralizing free radicals, which can cause oxidative stress and damage to cells. Consuming a variety of antioxidant-rich foods, such as fruits, vegetables, nuts, and whole grains, helps protect the body against chronic diseases and inflammation. Antioxidants support immune function and may improve athletic performance by aiding recovery after intense exercise. They can also enhance overall health by promoting cardiovascular health and reducing the risk of neurodegenerative diseases. Incorporating antioxidant-rich foods into meals ensures a balanced and health-promoting diet.
