Why should you
start AIP?
AIP isn’t a diet—it’s a proven framework to calm inflammation, restore nutrient density, and reveal which foods truly support your health. And it’s not forever restrictive—you start with elimination, then reintroduce foods to build a personalized, sustainable way of eating.
What began as a grassroots experiment is now a global movement, validated by clinical research and fueled by countless recovery stories. AIP is helping people with conditions like Hashimoto’s, IBD, rheumatoid arthritis, and psoriasis improve their health—and it can help you, too.

AIP in 2026:
Core and Modified Eliminations
Since its creation in 2011, AIP hasn’t had a major update—until now. Recently, the Autoimmune Protocol was revised for the first time, reflecting both the growing body of research and the lived experiences of thousands of patients.
Now you have two ways to approach elimination:
Core AIP
The original, comprehensive protocol used in medical studies, ideal for those needing a stricter approach.
Modified AIP
A less restrictive version, designed for accessibility, affordability, and sustainability, while still providing meaningful results.
No matter which you choose, you’ll have the confidence that you’re following the most current, evidence-based version of AIP.
