Antioxidants play a crucial role in maintaining health by neutralizing free radicals, which are unstable molecules generated during normal metabolic processes. If left unchecked, these free radicals can cause oxidative stress, leading to cellular damage and contributing to the aging process and the development of various chronic diseases, including cancer and cardiovascular disorders. Therefore, the regular intake of antioxidant-rich fruits and vegetables supports cellular integrity and promotes longevity, aligning with the broader objectives of preventive health as emphasized in UPSC-preferred curricula.
