You've probably heard that eating fruits and vegetables rich in antioxidants is an important part of a healthy lifestyle. But what exactly are antioxidants, and why do they matter?
Antioxidants are naturally occurring compounds found throughout the body and in many foods. They help protect cells from oxidative stress caused by free radicals, which are unstable molecules produced during normal metabolic processes and through everyday environmental exposures.
Maintaining a balance between antioxidants and free radicals is one part of supporting normal cellular function and overall wellness.

Free radicals are unstable molecules that naturally form during normal body processes, including:
Environmental factors such as air pollution, tobacco smoke and ultraviolet (UV) exposure can also contribute to free radical production.
While free radicals serve normal biological functions, excessive oxidative stress may affect normal cellular health over time.
Antioxidants help neutralize free radicals, supporting the body's natural defense against oxidative stress.
The body produces some antioxidants naturally, while many others are obtained through a balanced diet rich in fruits, vegetables, nuts, seeds and whole grains.
Many vitamins, minerals and plant compounds have antioxidant properties.
