Are you living with rheumatoid arthritis or osteoarthritis?
OMRF scientists want to study the effects of wild blueberries on inflammation biomarkers in the blood and gut health.
You can help. Join our study.
Oklahoma Medical Research Foundation’s Rheumatoid Arthritis and Osteoarthritis Research Centers of Excellence are conducting a clinical nutrition study to analyze the effects of dietary wild blueberries on gut health and inflammation and joint pain.
Goals
The purpose of this study is to find out about the effects of blueberry intake on blood markers of inflammation and fecal bacteria and to examine how these effects may impact joint health.

Criteria for inclusion
- Between the age of 45-75
- Mid-to-moderate multi-joint osteoarthritis in one or both knees (must have a diagnosis with radiographic evidence) OR diagnosis of rheumatoid arthritis with no changes in immunosuppressive treatment in the past 12 weeks
Interested parties will be asked to complete questionnaires and screening tests as well as a medical history. If enrolled, you will begin the 26-week study and be provided with a blueberry or control (placebo) powder to consume twice daily for 12 weeks. After the initial 12 weeks is complete, participants will have two weeks where they do not consume the powder. After that two-week period, the powders will be switched and participants will continue the regimen for another 12 weeks. Participants will also be asked to keep a food log during the study.
