Oxidative Stress, Pain and Disease

 

“Oxidative stress” is an imbalance in the body of excessive “oxidants” (oxidizing or chemically active, agents, including free radicals obtained from the diet or produced by the body) and insufficient “antioxidants” (chemically active agents that are also obtained from the diet or produced by the body) and neutralize oxidants. This overabundance of oxidants causes damage to biomolecules, (lipids, proteins, DNA), cells and tissue, eventually contributing to aging and chronic diseases including chronic inflammation, arthritis and pain, atherosclerosis, cancer, diabetes, heart diseases and stroke.

Oxidative Stress

“Oxidative stress” is an imbalance in the body of excessive “oxidants” (oxidizing or chemically active, agents, including free radicals obtained from the diet or produced by the body) and insufficient “antioxidants” (chemically active agents that are also obtained from the diet or produced by the body) and neutralize oxidants. This overabundance of oxidants causes damage to biomolecules, (lipids, proteins, DNA), cells and tissue, eventually contributing to aging and chronic diseases including chronic inflammation, arthritis and pain, atherosclerosis, cancer, diabetes, heart diseases and stroke.
 

Free radicals

Free radicals are molecules with unpaired electron in their outer orbit. This unpaired electron makes the free radical highly reactive with molecules in cells and tissues. While free radicals  have beneficial roles in some biochemical activities, excessive levels of free radicals leads to tissue damage.  People are constantly exposed to free radicals in their environment created by electromagnetic radiation, pollutants and cigarette smoke and natural sources such as radon and cosmic radiation. In addition, the human body produces free radicals and other reactive species as byproducts of numerous physiological, metabolic and biochemical processes. The most common cellular free radicals are hydroxyl (OH·), superoxide (O –·) and nitric monoxide (NO·). Other molecules like hydrogen peroxide (H2O2) and peroxynitrite (ONOO–) generate free radicals through various biochemical reactions.

 

Antioxidants

Antioxidants are produced in the mitochondria within cells throughout the body and serve to detoxify free radicals and protect tissues from such damage. Another important source of antioxidants is the diet, and diets rich in antioxidants are protective against the disease processes noted above. Fruits and vegetables are especially rich in antioxidants including . vitamin E, vitamin C, vitamin A, curcumin, resveratrol, glutathione, arginine, citrulline, taurine, creatine, selenium, zinc, and polyphenols found in tea. .Diets rich in fruits and vegetables result in high blood antioxidant capacity and reduced oxidative stress. Antioxidant activity is further supported by antioxidant enzymes, e.g. superoxide dismutase, catalase, glutathione reductase and glutathione peroxidase that exert synergistic actions in removing free radicals.

Individual Antioxidants:

Vitamin C
Coenzyme Q (CoQ-10)
Vitamin E
Curcumin
Resveratrol
Beta-carotene

Beta carotene is a yellow-red-orange pigment found in plants and fruits, especially carrots and colorful vegetables. The name beta carotene comes from the Greek “beta” and Latin “carota” (carrot). 
  1. Beta carotene is converted into vitamin A, an essential vitamin
  2. Vitamin A is toxic at high levels
  3. Beta carotene is a carotenoid and an antioxidant
  4. Foods rich in vitamin A include onions, carrots, peas, spinach and squash
  5. Some evidence suggests that beta carotene might slow cognitive decline
  6. Beta carotene supplements interact with certain drugs, including statins
  7. Beta carotene might help older people retain their lung strength as they age.
