Describe the role of antioxidants in a healthy diet.

Antioxidants play a crucial role in a healthy diet by helping to protect the body from damage caused by free radicals. Free radicals are unstable molecules formed during normal metabolic processes as well as through external sources such as pollution and UV radiation. These molecules can lead to oxidative stress, which is associated with various chronic diseases and the aging process. Antioxidants neutralize free radicals, thereby minimizing their potential harm and supporting overall health.

While antioxidants do have some benefits for muscle recovery and skin health, their primary function is broader, focusing on cellular protection and reducing the risk of chronic illnesses. They are naturally found in many foods, particularly fruits, vegetables, nuts, and whole grains, rather than being limited to vitamin supplements. This comprehensive role in safeguarding cellular integrity and promoting health distinguishes antioxidants within a balanced diet.
