However, there are some links between diet and arthritis. For example, getting enough milk and vitamin C is associated with a somewhat lower risk of gout. Gout is a disorder characterized by too much uric acid in the blood and tissues. Crystals of uric acid are deposited in the joints, where they cause a type of arthritis called gouty arthritis.
The risk of developing gout appears to be higher among people with a diet that is high in:
- high-fructose corn syrup (as in sweetened soft drinks)
- purines (a form of protein found in sardines, liver and other organ meats)
Another condition in which diet may affect arthritis risk is celiac disease. This is an immune reaction to gluten in the diet. Gluten is a component of wheat and other grains. By eliminating gluten from the diet (by avoiding many bread products, cereals and a host of other common foods), the condition can be controlled and the arthritis improved.
There is no clear connection between diet and these common forms of arthritis:
- rheumatoid arthritis
Perhaps the most important connection between diet and arthritis is the well-known link between obesity and the most common type of arthritis, osteoarthritis. The best way to reduce your risk of developing osteoarthritis is to maintain a healthy weight and avoid a diet that contributes to obesity. Recent studies suggest that obese people with osteoarthritis have less pain if they lose weight. (However, genetics have an impact on osteoarthritis risk. Changes in diet alone do not reliably reduce arthritis symptoms.)
We may someday figure out that diet matters much more than we realize now. But, at the current time, diet plays little or no role in the development of most joint diseases.
