What role do antioxidants play in nutrition?

Antioxidants play a crucial role in nutrition primarily through their ability to prevent oxidative stress within the body. Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body, leading to cellular damage that can contribute to various diseases, including cancer and heart disease. Antioxidants neutralize free radicals, thus helping to maintain cellular integrity and overall health.

The function of antioxidants involves various compounds, including vitamins C and E, selenium, and flavonoids, which are found in many fruits, vegetables, nuts, and whole grains. By incorporating these antioxidant-rich foods into one's diet, individuals can help bolster their body's defenses against oxidative damage, supporting long-term health and reducing inflammation.

Other choices do not align with the primary role of antioxidants. While individuals might think antioxidants could enhance taste, they do not have a direct function related to flavor attributes. Protein synthesis is facilitated by amino acids and other specific nutrients rather than antioxidants. Similarly, while some nutrients support digestion, antioxidants do not have a primary role in this function. Understanding the protective effects of antioxidants highlights their significance in promoting health and preventing disease.
