Antioxidants, particularly vitamin C and vitamin E, act as protective agents against oxidative stress. These nutrients combat free radicals in the body, which can cause cellular damage and contribute to chronic diseases. Consuming foods rich in these vitamins, such as fruits, vegetables, nuts, and seeds, helps maintain cellular health and supports the immune system. Regular intake of antioxidants promotes overall health and may reduce the risk of developing various health conditions related to oxidative damage.
