The role of antioxidants in nutrition is crucial for combatting oxidative stress in the body. Antioxidants, such as vitamins C and E, and other compounds like flavonoids, help neutralize free radicals—unstable molecules that can damage cells and lead to chronic diseases. Consuming a diet rich in antioxidant-containing foods, such as fruits, vegetables, nuts, and whole grains, can enhance overall health and support the body's defense against inflammation and aging. Thus, a sufficient intake of antioxidants plays a vital role in promoting long-term well-being.
