Antioxidants combat oxidative stress by neutralizing free radicals, which are harmful molecules that can damage cells. This process reduces the risk of chronic diseases, including heart disease and cancer. Antioxidants, such as vitamins C and E, flavonoids, and polyphenols, are abundant in fruits, vegetables, and whole grains. The intake of these compounds helps maintain a balance between oxidants and antioxidants in the body. Regular consumption of antioxidant-rich foods contributes to enhanced cellular health and overall well-being.
