14. Gluten
Gluten is a protein found in wheat, barley, and rye, and can be problematic for individuals with arthritis who also have a gluten sensitivity or celiac disease. Consuming gluten can trigger an inflammatory response in these individuals, leading to increased joint pain and stiffness.
If you suspect that gluten may be contributing to your arthritis symptoms, consider trying a gluten-free diet for a few weeks to see if your symptoms improve. If you notice a positive change, you may want to continue avoiding gluten or consult with a healthcare provider for further guidance. (10)
