The modern guidebook for today’s AIP journey
If you’re new to the Autoimmune Protocol (AIP) diet, returning to AIP after time away, or wondering whether Core AIP or Modified AIP is the right place to start, this page will help you decide.
If you’re looking for a clear, research-informed, and sustainable approach to the Autoimmune Protocol, this is the book I recommend starting with.
The New Autoimmune Protocol is the first official update to the AIP in years, written by Mickey Trescott — one of the founding leaders of the Autoimmune Protocol movement and a voice I’ve trusted throughout my own healing journey.
As autoimmune diagnoses continue to rise, so has our understanding of what actually helps people heal. Feedback from thousands of practitioners, millions of patients, and emerging research has made one thing clear: AIP needed to evolve.
The New Autoimmune Protocol builds on the original science-backed framework, integrating emerging research and years of clinical and practitioner feedback to create a more flexible, sustainable approach.
What makes this book different
This guidebook is designed for real people navigating autoimmune disease — not just theory — and reflects how the AIP is being used successfully today.
Rather than a one-size-fits-all approach, Mickey explains a more flexible, realistic framework that meets people where they are — without abandoning the science-informed foundation that makes AIP effective.
Inside, you’ll find:
- A clear explanation of autoimmune disease and the principles behind AIP
- Updated research and clinical insight
- A new, more accessible option called Modified AIP Elimination
- Practical meal plans and 70+ nourishing recipes
Many people are now seeing meaningful improvements without needing the most restrictive version of AIP right away, and this book explains how emerging research and clinical insight support that approach.
Core AIP vs. Modified AIP — explained
One of the most common questions I hear is: What is the difference between Core AIP and Modified AIP? This book answers that clearly.
The book is thoughtfully divided into two essential paths:
Core AIP Recipes & Meal Plans
This follows the traditional AIP elimination phase, removing:
- Grains and gluten
- Dairy and eggs
- Nightshades and Legumes (including soy)
- Nuts and seeds (and their oils)
- Alcohol
- Processed food additives
Modified AIP Recipes & Meal Plans
This newer approach is less restrictive and may be appropriate for many people, including the addition of:
- Ghee
- Rice and pseudo-grains
- Legumes (excluding soy)
- Seeds
The goal is flexibility, personalization, and long-term sustainability — not perfection.
More than a cookbook
This isn’t just a collection of recipes.
The New Autoimmune Protocol walks readers through all the essential phases of AIP:
- Transition
- Elimination
- Reintroduction
Whether you choose Core or Modified AIP, the book equips you with knowledge, structure, and flexibility to support real-life healing.
How this fits with the AIP Recipe Collection
Many people ask how to combine a solid AIP education with day-to-day cooking and meal planning. This is where these resources work together.
I see this book as the foundation and the framework behind the AIP.
Here at the AIP Recipe Collection, my focus is helping you apply that knowledge day to day with practical cooking, meal ideas, and ongoing support.
They work best together!
