Antioxidants: powerful free radical fighters
Although oxygen is essential for life, it can also have adverse effects on your body. In the normal process of using oxygen, chemical changers create reactive unstable oxygen molecules called free radicals occur in the body: these free radicals can damage cells and structures within the cells, including genetic material (DNA) .
Free radicals also may form in response to external factors:
cigarette smoke and alcohol
pollutants like nitrogen oxide , ozone
forms of radiation like ultra violet light , x-rays.
If genetic material is affected, it can be replicated in new cells, contributing to cancer or other health issues.
Free radicals may also weaken artery walls, allowing to fatty deposits that can lead to heart disease.
Cells have special agents for combating free radicals and repairing molecular damage. These are called antioxidants. A lot of research suggests that antioxidants may play important roles in preventing or delaying heart disease, cancer, other ills, and may even slow down the effects of ageing.
