What role do antioxidants play in nutrition?

Antioxidants play a crucial role in nutrition by protecting cells from damage caused by free radicals, which are unstable molecules that can harm cellular components such as DNA, proteins, and cell membranes. This cellular damage is linked to various diseases, including cancer, heart disease, and aging-related conditions. By neutralizing free radicals, antioxidants help maintain the integrity of cells, support the immune system, and contribute to overall health.

Free radicals are generated through normal metabolic processes, environmental factors, and exposure to toxins. Antioxidants, which include vitamins (like vitamins C and E), minerals (such as selenium), and various phytochemicals found in fruits and vegetables, work synergistically to combat oxidative stress and reduce inflammation in the body.

The other choices do not accurately represent the function of antioxidants. While they may provide other benefits, such as aiding digestion or enhancing flavor, these functions are not directly related to the protective role antioxidants play in cell health.
