Anti-Inflammatory Dietary Intervention for Rheumatoid Arthritis

Study Purpose

The primary objective of this study is to assess if there is a significant difference in the mean disease activity score in individuals with RA participating in a dietary intervention compared to those in the control group measured by DAS-28. Other measures to track disease activity will include monitoring number and severity of disease flares and any changes in medications. This will be done by completing a single-blinded randomized controlled trial, parallel in design. The study population will consist of adults diagnosed with Seropositive and Seronegative RA based on the American College of Rheumatology criteria. Participants will have low, moderate, or high disease activity based on DAS-28 where the investigator feels that they can see improvement from a dietary intervention.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

Per the Schedule of Assessments, upon enrollment, participants will be required to come in for a total of five on site visits. The first visit, also known as the baseline visit, will require participants to provided informed consent after all eligibility criteria is met. Subsequently, participants' Demographics, Medical History, EULAR/ACR classification, and physicians' assessments will be documented. Participants' vital signs will be checked and a thorough physical exam will also be performed after which safety labs will be drawn in addition to a routine urinalysis. Participants will complete outcome surveys and a food frequency questionnaire. Participants' body composition will be measured. Concomitant medications will be reviewed. Each participant will receive nutrition education from an approved MD or a consultation with an approved RD depending on the group to which they have been randomized. Participants who receive consultations with an RD will have seven follow up visits after the baseline visit.

Arms & Interventions


Other: Standard of Care (Control Group)

Physicians will follow standard of care and instruct participants in the control group to follow a Mediterranean diet higher in vegetables and fruits[19]. Patients will be provided with a handout detailing the basics of the Mediterranean diet. At follow up visits, physicians will ask participants about how they have been eating and if they have been following the guidelines.

Experimental: Anti-inflammatory Diet (Intervention Group)

An 8-week nutrition program consisting of an individualized elimination diet and systematic food reintroduction implemented and supervised by a Registered Dietitian. Clinical trials have shown some benefit from elimination diets for individuals with autoimmune disease [18]. The specifics of the elimination diet including duration and foods included will be individual and up to the RDs discretion based on the patient's medical and diet history, willingness, current diet, preferences, goals, and ability. The initial diet instruction with a Registered Dietitian will be a one-hour, individual secure video call, with nutrition evaluation/assessment and education on elimination diet protocol. Follow up visits will be approximately 20-30 minutes for the subsequent 7 weeks.


Behavioral: - Anti-inflammatory diet

Patients randomized to the intervention group will work with a registered dietitian to create an individualized diet program to help reduce inflammation and Rheumatoid arthritis related symptoms.

Other: - Control/Standard of Care

Patients randomized to the control group will be following standard of care where their doctor will instruct them to follow a Mediterranean diet and provides them with an instructional sheet.
