What health benefit do antioxidants provide?

Antioxidants play a crucial role in the body by protecting cells from oxidative stress and damage caused by free radicals. Free radicals are unstable molecules that can harm cellular structures, including DNA, proteins, and lipids, leading to various chronic diseases and aging. Antioxidants neutralize these free radicals by donating electrons, thereby reducing their reactivity and preventing cellular damage. This protective function is vital for maintaining overall health and mitigating the risk of conditions such as heart disease, cancer, and neurodegenerative disorders.

Other options do not accurately represent the primary function of antioxidants. For example, while some vitamins and minerals can aid in the absorption of carbohydrates or contribute to the regulation of blood pressure, those processes are not the fundamental role of antioxidants. Similarly, although certain compounds can enhance immune response, this is not the primary mechanism through which antioxidants provide health benefits. Thus, the answer highlighting the protection against oxidative stress and free radical damage encompasses the central health benefit associated with antioxidants.
