Antioxidants play a crucial role in overall health by combatting oxidative stress caused by free radicals. These unstable molecules can damage cells and contribute to chronic diseases such as heart disease, diabetes, and certain cancers. Consuming a diet rich in antioxidants, found in fruits, vegetables, nuts, and whole grains, helps neutralize free radicals, protecting cellular integrity and promoting immune function. By reducing inflammation and supporting the body's defense mechanisms, antioxidants contribute to long-term health and wellbeing, making them an essential part of any balanced diet.
