What is the role of antioxidants in nutrition?

Antioxidants play a crucial role in nutrition primarily by protecting cells from damage caused by free radicals. Free radicals are unstable molecules that can cause oxidative stress, leading to cellular damage and contributing to various diseases, including cancer, heart disease, and neurodegenerative disorders. Antioxidants neutralize these free radicals, thereby minimizing their harmful effects.

These protective compounds, which include vitamins (like vitamin C and E), minerals (such as selenium), and various phytochemicals, assist in maintaining overall health by reducing oxidative stress in the body. By scavenging free radicals, antioxidants help ensure that cellular functions remain intact, which is vital for preventing chronic illnesses and supporting long-term well-being.

The other options do not accurately reflect the primary function of antioxidants. They focus on aspects like calorie intake, fat storage, and protein synthesis, which are not related to the protective qualities that antioxidants provide against oxidative damage.
