Free radicals, reactive oxygen species (ROS), and reactive nitrogen species are generated by the body through various endogenous systems and external factors. An imbalance between free radicals and antioxidants leads to oxidative stress, which damages lipids, proteins, and DNA, contributing to various diseases. Synthetic antioxidants like butylated hydroxytoluene and butylated hydroxyanisole are considered harmful, prompting a search for natural, non-toxic antioxidants. Antioxidants, such as vitamins C, E, and beta-carotene, help neutralize free radicals, reduce oxidative damage, and prevent diseases. Free radicals are involved in aging, cancer, atherosclerosis, and other conditions. Antioxidants play a crucial role in cellular defense by scavenging free radicals, repairing damaged molecules, and enhancing immune function. Natural sources of antioxidants include plants, fruits, vegetables, and medicinal herbs. Functional foods and nutraceuticals derived from these sources offer health benefits by reducing oxidative stress and preventing chronic diseases. The traditional Indian diet, rich in antioxidants from spices and medicinal plants, provides a natural alternative to synthetic antioxidants. Research highlights the importance of dietary antioxidants in maintaining health and preventing diseases. The use of natural antioxidants in food, cosmetics, and medicine is increasingly favored due to their safety and effectiveness. Overall, antioxidants are essential for combating oxidative stress and promoting health.Free radicals, reactive oxygen species (ROS), and reactive nitrogen species are generated by the body through various endogenous systems and external factors.
