Antioxidants support overall health by neutralizing free radicals, which can cause cellular damage and contribute to aging and various diseases. By protecting cells from oxidative stress, antioxidants help maintain healthy bodily function and reduce inflammation. Sources of antioxidants include fruits, vegetables, nuts, and whole grains. Regular intake of these substances is linked to decreased risk of chronic diseases such as heart disease and cancer. Thus, a diet rich in antioxidants can play a critical role in promoting long-term health.
