Free Radicals & Antioxidants
Free Radicals
Free radicals are atoms or molecules which possess an unpaired electron in its outermost shell. This state causes them to be highly reactive, looking to snatch an electron from any nearby molecule.
Free radicals are produced all the time within our bodies as a result of our daily metabolism and energy production. Free radicals are not always detrimental, playing an important role in many biological processes such as: fighting germs, killing bacteria and healing.
Problems arise when too many free radicals are formed, leaving the body's defence system overwhelmed. Free radical damage has been linked to the ageing process within the skin, heart disease, many forms of cancer, and even post-exercise muscle soreness.
Free radical activity can be increased through exposure to the Sun's UV rays, cigarette smoke, and pollution.
Antioxidants
Antioxidants work as scavengers, stabilising free radicals to prevent potential cell and tissue damage. By donating one of their own electrons they are able to neutralise the free radical and render them harmless.
The body has a number of mechanisms and natural defences to minimize free radical induced damage and to repair damage which does occur. These include enzymes (e.g. catalase, glutathione, and superoxide dismutase) containing minerals such as zinc and magnesium; antioxidants in the form of vitamin A, C and E; and other natural substances.
Diet
Antioxidants are crucial to our body's ability to manage and protect itself against cellular damage. A diet rich in antioxidants is a perfect way to supplement your body's natural defences.
