What is the role of antioxidants in nutrition?

Antioxidants play a crucial role in nutrition by helping to protect the body from damage caused by free radicals. Free radicals are unstable molecules that can damage cells, proteins, and DNA, potentially leading to chronic diseases such as cancer and heart disease. Antioxidants stabilize these free radicals by donating an electron, thereby neutralizing their harmful effects and reducing oxidative stress in the body.

Foods rich in antioxidants, such as fruits, vegetables, nuts, and whole grains, not only contribute to overall health but also support the immune system and may reduce inflammation. This protective function is essential for maintaining cellular integrity and promoting long-term health.

In contrast to the other options, antioxidants do not directly enhance the flavor of food, provide energy, or significantly increase nutritional value through cooking. Their primary role lies in their ability to combat oxidative damage and promote health.
