What role do antioxidants play in nutrition?

Antioxidants play a crucial role in nutrition by protecting the body from oxidative stress. Oxidative stress occurs when there is an imbalance between free radicals (unstable molecules that can cause cellular damage) and antioxidants in the body. Free radicals are generated through normal metabolic processes as well as from environmental factors such as pollution, radiation, and certain chemicals. Antioxidants neutralize these free radicals, thus preventing cell damage and reducing the risk of chronic diseases, including heart disease, cancer, and neurodegenerative disorders.

While providing energy is important, this role is typically fulfilled by macronutrients such as carbohydrates, fats, and proteins. Antioxidants themselves do not supply energy. They are not proteins essential for muscle building, as proteins serve different functions in the body. Furthermore, antioxidants are not a primary source of hydration; hydration is mainly achieved through water and fluid intake, rather than through antioxidant compounds.

Understanding the role of antioxidants in preventing oxidative stress highlights their significance in maintaining overall health and well-being. This reinforces the importance of incorporating a diet rich in fruits, vegetables, nuts, and whole grains, which are abundant in these protective compounds.
