What is the role of antioxidants in the body?

Antioxidants play a crucial role in safeguarding the body from harmful free radicals, which are unstable molecules that can cause cellular damage. Free radicals are often generated through various processes such as metabolism, environmental stressors, and exposure to pollutants. These molecules can lead to oxidative stress, contributing to aging, inflammation, and the development of various diseases.

Antioxidants neutralize free radicals by donating an electron, thereby stabilizing them and preventing them from causing further damage to cells and tissues. By doing so, antioxidants help maintain the integrity of cellular structures and support overall health. This protective role is vital for reducing the risk of chronic illnesses and supporting the body's natural defense mechanisms.

In contrast, the other options misrepresent the functions of antioxidants. They do not serve as a direct source of energy, nor do they provide structural support to cells, and they are not involved in food digestion. Rather, they are specifically recognized for their protective capabilities against oxidative damage, making the role of antioxidants in combating free radicals the most accurate choice.
