What is the major role of antioxidants in the body?

Antioxidants play a crucial role in protecting cells from oxidative damage. They are compounds that help neutralize free radicals—unstable molecules that can cause cellular damage by reacting with important cellular components like DNA, proteins, and lipids. High levels of oxidative stress can lead to various chronic diseases, including cancer, cardiovascular diseases, and neurodegenerative disorders.

By countering oxidative damage, antioxidants help maintain cellular integrity and promote overall health. They can be found in various food sources, particularly fruits and vegetables, which are rich in vitamins such as vitamin C and E, as well as other phytochemicals. This protective function of antioxidants is essential for the biological processes that keep our cells functioning optimally and preventing the progression of many diseases associated with aging and lifestyle factors.
