Antioxidants play a crucial role in nutrition primarily by helping to protect cells from damage. This protection is essential because oxidative stress, which results from an imbalance between free radicals and antioxidants in the body, can lead to cellular damage and contribute to various chronic diseases, including heart disease, cancer, and neurodegenerative disorders. Antioxidants neutralize free radicals, which are unstable molecules that can cause harm to cellular structures, including DNA, proteins, and lipids.

By preventing this oxidative damage, antioxidants support overall health and well-being. They are found in various foods, particularly fruits, vegetables, nuts, and whole grains, increasing the body’s ability to combat the harmful effects of oxidative stress.

The other options address aspects that do not align with the primary function of antioxidants. For instance, increasing appetite is typically associated with different dietary substances, and the facilitation of mineral absorption is influenced by other factors and nutrients rather than antioxidants alone. Similarly, hydration is more closely linked to fluid intake rather than the action of antioxidants. Thus, the significance of antioxidants in nutrition is best understood through their role in cell protection and maintenance of health.
