What is the primary function of dietary antioxidants?

The primary function of dietary antioxidants is to protect cells from oxidative stress. Oxidative stress occurs when there is an imbalance between free radicals—unstable molecules that can damage cells—and antioxidants, which help neutralize these harmful molecules. Antioxidants work by donating electrons to free radicals, thereby stabilizing them and preventing cell damage. This protective role is crucial for maintaining overall health, as oxidative stress has been linked to various chronic diseases, including cancer, heart disease, and neurodegenerative conditions.

While enhancing flavor, providing energy, and aiding in digestion are important aspects of certain nutrients or food components, they do not encompass the core role of dietary antioxidants. The influence of antioxidants on cellular health and disease prevention underscores their significance in a balanced diet rich in fruits, vegetables, and other sources of antioxidants.
