What role do antioxidants play in nutrition?

Antioxidants play a crucial role in nutrition by combating free radicals and reducing oxidative stress. Free radicals are unstable molecules that can damage cells, proteins, and DNA, leading to various health issues, including chronic diseases and aging. Antioxidants neutralize these free radicals, thereby protecting the body from oxidative damage. This protective effect helps maintain overall health, supports the immune system, and may reduce the risk of certain diseases.

The other options do not accurately represent the function of antioxidants. Antioxidants do not enhance muscle fatigue; in fact, they may help in recovery by reducing oxidative stress related to exercise. They also do not increase appetite and weight; rather, they serve a different physiological purpose. Additionally, antioxidants do not minimize collagen production. Instead, some antioxidants, such as vitamin C, support collagen synthesis, which is essential for skin health and elasticity. Thus, the role of antioxidants in combating free radicals and reducing oxidative stress is fundamental to their contribution to nutrition and overall health.
