Antioxidants: A Masterpiece of Mother Nature to Prevent Illness
Amrit Krishna Mitra
Abstract
Reactive oxygen and nitrogen species, generated in usual biochemical reactions with increased exposure to the environment can cause an imbalance in homeostatic process between oxidants and antioxidants leading to oxidative stress. Oxidative stress is primarily responsible for a wide array of human diseases such as neurodegenerative disorders (Alzheimer’s disease, Parkinson’s disease), diabetes, cancers, and rheumatoid arthritis. Therefore, a subtle balance between oxidation and antioxidation is an essential requirement in order to maintain a healthy biological system. Antioxidants, widely distributed among plants and animals are substances which can significantly prevent or inhibit the oxidative damage to cells. COVID-19 is a major threat to the entire world and the need to boost one’s immunity is crucial. This can be achieved by consuming antioxidants. Thus, this article attempts to delineate different types of antioxidants, their sources in Mother Nature, the need of antioxidants to maintain good health and their mode of action along with mechanisms.
