Antioxidants/System Essentials:
Antioxidants
-
You’ve heard all the talk about free radicals, but do you understand what they do? Free radicals are created by the body naturally during metabolism. However, when we are exposed to environmental toxins, such as air pollution or cigarette smoke, our bodies can create too many of these unstable substances.
-
Free radicals - also called oxygen radicals, oxygen free radicals, and singlet oxygen - lack a particle called an electron. In an attempt to become stable, they attack other cells to try to “steal” an electron. This attack harms the cells’ delicate membranes - and makes them a target for disease.
-
This process is called oxidation. Just like oxygen causes metal to rust, oxidation can also damage cells. In humans, the common signs of oxidation damage can be seen in the normal signs of aging, such as wrinkles and other skin changes.
-
Antioxidants neutralize free radicals by “donating” an electron to the unstable substances. After being neutralized, free radicals no longer attempt to damage cells and are harmless to the body.
Antioxidants and your health
-
During the 1960s, researcher Al Tappel first suggested that specific vitamins - particularly vitamin E - acted as antioxidants within the human body, offering it protection from the damage caused by free radicals. Since that time, researchers throughout the world have suggested that free radicals may play an important role in aging and the health issues that accompany it. They’ve gone so far as to suggest that antioxidants may offer the body support against free radical damage.
-
Researchers also believe that antioxidants prevent the oxidation of blood fats, such as cholesterol. Recent studies have suggested that the oxidation of blood fats may be a major cause of artery hardening.
Types of antioxidant nutrients
-
Early antioxidant research centered on vitamin E and its antioxidant properties. Since that time, however, many important nutrients have been identified as antioxidants These include:
-
Researchers also believe that antioxidants prevent the oxidation of blood fats, such as cholesterol. Recent studies have suggested that the oxidation of blood fats may be a major cause of artery hardening.
-
Beta carotene : This carotenoid is the plant pigment which gives carrots their orange color. It’s an antioxidant which promotes immune, skin, and cardiac health.
-
Vitamin C : This immune-supportive nutrient is considered the most important antioxidant for extracellular (outside of cells) activity. Vitamin C also helps “recycle” vitamin E, which increases vitamin E’s antioxidant activity.
-
OPCs : These natural phytonutrients, also known as oligomeric proanthocyanidins, have been shown to offer powerful antioxidant effects. Natural substances rich in OPCs include grape seeds, grape skins, and Pycnogenol, extracted from the bark of the French maritime pine.
-
Bioflavonoids : Natural plant substances are well known to enhance the action of vitamin C and support blood circulation as an antioxidant. It also treats allergies, viruses or inflammatory conditions such as arthritis.
-
Selenium : This essential mineral offers antioxidant protection and supports reproductive health in both men and women.
-
CoQ10 : This coenzyme, essential in speeding up some metabolic processes, has also been shown to offer extensive antioxidant effects. It is particularly supportive of the heart and circulatory system.
