Antioxidants play a crucial role in protecting cells from oxidative stress, which is caused by free radicals—unstable molecules that can damage cellular structures, including DNA, proteins, and cell membranes. Oxidative stress is linked to various health issues, including chronic diseases and aging. Antioxidants neutralize these free radicals, thereby preventing potential damage and maintaining cellular integrity.

By incorporating antioxidants into your diet, typically through fruits, vegetables, nuts, and whole grains, you provide your body with the tools it needs to combat oxidative stress. This protective function contributes to overall health and supports the body's ability to function optimally, reducing the risk of developing certain diseases.
