What role do antioxidants play in the body?

Antioxidants play a crucial role in protecting the body from the damaging effects of free radicals. Free radicals are unstable molecules that can cause oxidative stress, leading to cellular damage and contributing to various health issues, including chronic diseases and aging. Antioxidants neutralize free radicals by donating an electron, which stabilizes these molecules and mitigates their harmful effects. This protective function of antioxidants is essential for maintaining overall health, supporting the immune system, and reducing inflammation.

The other roles presented, such as promoting the growth of pathogens or enhancing blood clotting, do not accurately represent the functions of antioxidants within the body. Similarly, while some nutrients can aid in digestion, antioxidants are primarily recognized for their protective properties against oxidative damage rather than digestive processes. Thus, the correct answer highlights the significant protective function that antioxidants serve in the body.
