What are free radicals? What kind of damage can they do to your body? ( by WebMd)
"Free radicals" are unstable atoms, or molecules, in your body. They are missing important components that would make them more stable. So they rob other cells of those components to meet their needs. This causes injury to previously healthy cells. Over time, this damage can lead to diseases such as cancer, heart disease, or Alzheimer’s disease.
Your body produces free radicals through its normal processes. Your body also contains antioxidant molecules, which deactivate harmful free radicals. But things like cigarette smoking, pollution, and excessive alcohol consumption can create so many free radicals that your body has a hard time defusing them on its own.
