If you’ve been living the Autoimmune Protocol, you already know how powerful it can feel.
But did you know AIP has been studied in clinical research — with measurable results?
Let’s talk about what the science actually says.
AIP & Crohn’s & Ulcerative Colitis
In 2017, a pilot study led by Dr. Sarah Ballantyne and Dr. Arvind Venkatraman examined AIP in patients with inflammatory bowel disease (IBD).
The study:
“Efficacy of the Autoimmune Protocol Diet as Part of a Multidisciplinary, Supported Lifestyle Intervention for Inflammatory Bowel Disease”
Published in Inflammatory Bowel Diseases (2017)
Here’s what happened:
- Participants had longstanding IBD, with an average disease duration of about 19 years
- 73% achieved clinical remission by week 6
- Improvements were seen as early as week 3
- Quality of life scores significantly improved
-
Endoscopic improvements were observed in some participants
What makes these findings especially compelling is that the participants were not newly diagnosed. Many had been living with their condition for nearly two decades. Yet within weeks, measurable improvements were documented in the published data. These results challenge the assumption that after years of disease progression, meaningful change is no longer possible. Instead, they suggest that even long-standing autoimmune conditions may still respond to a comprehensive functional nutrition and lifestyle approach.
AIP & Hashimoto’s Thyroiditis
In 2019, Mickey Trescott, NTP, and Angie Alt, NTC, co-authored a pilot study:
“Clinical Improvements in Hashimoto’s Thyroiditis Following an Autoimmune Protocol Diet and Lifestyle Intervention” Published in Cureus (2019)
Results after 10 weeks:
- Significant improvement in quality of life scores
- Significant reduction in high-sensitivity C-reactive protein (hs-CRP), a marker of systemic inflammation
-
Reduction in symptom burden
Interestingly, thyroid antibodies did not significantly change during the short study period, which tells us something important:
Even when lab markers are slow to shift, symptom relief and inflammation reduction can still occur.
A 12-week study observed improvements in symptoms such as malaise and actual changes in thyroid hormone levels within reference ranges, along with some shifts in autoimmune markers and thyroid size on ultrasound. In some cases, patients needed their medication dosage to be reduced.
Taken together, these studies support the idea that AIP can play a supportive role in symptom management and inflammation reduction, even when traditional lab markers don’t change dramatically. Which matters deeply for patients.
AIP & Rheumatoid Arthritis
A 2021 pilot study explored AIP in women with rheumatoid arthritis:
“The Autoimmune Protocol Diet Improves Patient-Reported Outcomes in Rheumatoid Arthritis” Published in Frontiers in Nutrition (2021)
Participants experienced:
- Significant improvement in disease activity scores (e.g., RAPID3)
- Reduction in pain
- Meaningful improvements in fatigue and overall well-being
This early evidence suggests AIP can have a positive impact as part of a treatment therapy for RA as well.
What Does This Mean?
While larger randomized controlled trials are still urgently needed, AIP has demonstrated efficacy in improving symptoms and quality of life in multiple autoimmune conditions.
Most autoimmune research focuses on medication alone, and medication can absolutely be life-saving and necessary, but autoimmunity is complex — and no single strategy is universally effective. The growing body of research suggests that AIP can be a meaningful piece of the healing puzzle either alongside medication or, in some cases, as a structured standalone intervention under medical supervision. That flexibility is part of its power. It isn’t about rejecting medicine; it’s about expanding the therapeutic toolbox.
Research Is Growing — And Advocacy Is Essential
Autoimmune disease affects nearly 50 million Americans, yet research funding still does not reflect the true scale, complexity, or economic impact of these conditions.
As patients and practitioners, our role is to keep asking the deeper questions — and to advocate for solutions that expand options. Several studies examining the impact of the Autoimmune Protocol (AIP) on additional autoimmune conditions are currently in development, pending funding and institutional support.
Because research matters, Urban AIP is joining the Autoimmune Association and dozens of autoimmune patients in Washington, DC on March 19 to meet with elected officials and advocate for:
- Increased federal funding for autoimmune research
- Recognition of nutrition and lifestyle interventions as legitimate components of treatment plans
- Expanded integrative and collaborative care models
- Patient-centered research priorities
- Improved access to safe, effective, and affordable medications
We deserve more than symptom management. Our experience deserves recognition, our food deserves funding, and our healing deserves choice.
We are proud to stand alongside our community — providing meals that make your healing journey sustainable in daily life while advocating for the science that will continue to strengthen and validate its role in autoimmune care.
Frequently Asked Questions
FAQ #1: Does clinical research support the Autoimmune Protocol (AIP) diet?
Answer: Yes. Pilot studies published in Inflammatory Bowel Diseases (2017), Cureus (2019), and Frontiers in Nutrition (2021) found that the Autoimmune Protocol (AIP) was associated with improvements in symptom severity, quality of life, inflammatory markers, and disease activity scores in conditions such as inflammatory bowel disease, Hashimoto’s thyroiditis, and rheumatoid arthritis. While larger randomized trials are still needed, early evidence suggests AIP can be a meaningful complementary strategy alongside medical care.
FAQ #2: Can AIP help even if autoimmune disease has been present for many years?
Answer: Emerging research suggests it can. In the 2017 IBD study, participants had lived with their condition for an average of 19 years, yet 73% achieved clinical remission by week six. These findings indicate that even long-standing autoimmune conditions may still respond to comprehensive nutrition and lifestyle interventions like AIP, particularly when implemented with medical supervision.
