Oxidative stress is one of the causes of arthritis. We are just beginning to understand the role that oxidative stress plays in osteoarthritis, rheumatoid arthritis and other chronic diseases.
What is Oxidative Stress?
Simply, oxidative stress is a condition of the cells of the body where the byproducts of oxygen metabolism are interfering with the repair processes of the cells. If your cells were a machine, oxidative stress would be the rust. Those of us beyond a certain age know that, as we age, our joints sometimes feel a bit rusty.
What is arthritis?
The human skeleton has 206 bones most of which come together in some form of movable joint that is designed to work smoothly for 120 years or so. A miracle of natural design, each movable joint is lubricated by a bag of fluid (synovial cavity) that is surrounded by smooth slippery cartilage. The bag of fluid and the cartilage keep the bones from touching and make the movement of the joint effortless—at least while we’re young.
When the lubrication system in a joint malfunctions, we call it arthritis, literally an infected joint. There are two general kinds of arthritis, osteoarthritis which is damage to the articular cartilage. and rheumatoid arthritis which involves extra tissue developing between the bag of fluid and the cartilage. Once the extra tissue starts interfering with the movement of the joint, unhelpful changes start occurring in the cartilage and in the bag of fluid. Research has predicted that a third of everyone over 65 has visible damage to the cartilage in their hands, feet, knees or hips.
Why do we get arthritis?
There probably isn’t a single cause. Injury is part of the answer, but there has to be more than that. Inactivity contributes to arthritis. We need movement to keep the tissues lubricated and to flush dead cells and toxins out of the joint. Oxidative stress is part of it too. Reactive Oxygen Species (ROS) are molecules that can damage tissues. Free radicals are one form of ROS. Antioxidants in our diet or supplements help to control ROS molecules.
The cartilage that helps joints to move smoothly has no blood supply of its own; it relies on the movement of other tissues to bathe it in fluids that contain nutrients and remove waste. Without movement the fluids are toxic and stagnant while the cartilage is starved of nutrients.
The feeding and cleansing of the bag of fluid also depends on the movement of joints. So movement is a factor. As we age, many of us become more sedentary.
Another contributing factor may be the acid-base balance in the body. Many Americans eat an artificial diet that makes the body more acid. A more natural diet such as the Mediterranean Diet, makes the body slightly alkaline--as nature designed it. Hormones and enzymes are chemical messengers that travel around the body helping to coordinate healing processes. The SAD diet alters the acid-base balance so that the body is more acid; this interferes with the biochemical reactions that produce hormones and enzymes and disrupt their communications once their created.

What can we do about arthritis?
- Care for injured joints as recommended by your healthcare professional. Don’t just take a pain-reliever; actively heal the joint through hot or cold compresses—whichever your doctor recommends, or immobilizing the joint temporarily. Joints heal slowly so care for the joint, following your doctor’s instructions, beyond the point when the pain goes away.
- Keep your body as active as possible.
- Maintain a full range of motion in all your joints.
- Avoid junk food
- Avoid coffee and sodas
- Eat a Mediterranean diet.
- Supplement your diet with antioxidants.
- Research arthritis in your favorite search engine; there's plenty of good information on the internet.
