Q1. Regular intake of fresh fruits and vegetables is recommended in the diet since they are a good source of antioxidants. How do antioxidants help a person maintain health and promote longevity?
Explanation
Any substance that can inhibit the formation of unstable molecules known as free radicals, which harm DNA, cell membranes, and other components of cells, is referred to as an "antioxidant." Free radicals grab electrons from other molecules in order to complete their electron complement, which causes those molecules to suffer damage. Regular consumption of fresh fruits and vegetables is recommended because they are rich sources of antioxidants. Antioxidants play a crucial role in maintaining health and promoting longevity by neutralizing free radicals produced during metabolism. Free radicals are unstable molecules that can damage cells, proteins, and DNA, contributing to ageing and various diseases. By donating electrons, antioxidants stabilize free radicals, thereby preventing cellular damage and supporting overall health.
