The Definitive Guide to the Paleo Autoimmune Protocol (AIP)

Louise | February 4
everything you need to know about the paleo autoimmune protocol (AIP)

This article is a little bit more important than usual.

So it’s also a little bit longer than usual. But you should read it all. Especially if you have an autoimmune disease, and probably even if you don’t.

I get a lot of emails from readers asking about the Paleo Autoimmune Protocol (often abbreviated “AIP”).

Questions like:
“What is it?”
“Is it right for me?”
“How do I do it?” and
“Will it help me with ______ autoimmune disease?”

Unfortunately, there just wasn’t a great article or series of articles that clearly answered all of these questions. And that was a shame.


That’s why I’ve created this website (as well as this particular article).

It’s designed as a very thorough but easy-to-read guide to AIP, including a comprehensive, printable list of foods that are allowed or not allowed on AIP that you can have emailed to you by clicking below or at the end of the article.

There’s also a handy AIP FOOD TABLE below that you can Pin, so keep reading!

UPDATE: since publishing this article, I’ve also created a beautifully designed AIP 101 Guide that you can download for free (just scroll to the top and click the green button there).

What is an Autoimmune Disease?

The first time someone told me they had an autoimmune disease, I thought they meant they had AIDS (yes, I was quite clueless, despite the fact that I actually have an autoimmune disease). For the difference between Autoimmune Disease (AID) and Acquired Immune Deficiency (AIDS), check out this article.

Let me begin by explaining the basics of an autoimmune disease, because the chances are that you might have one!

Autoimmune diseases occur when your body’s own immune system starts attacking your own body’s proteins. This happens because your body thinks that those proteins are a foreign substance (e.g., a bacteria) that need to be destroyed. Unfortunately, this can end up causing widespread destruction of your own organs and cells instead.

There are a ton of different autoimmune diseases (some may not have even been identified, and many of them are obscure like the one I have). Most autoimmune diseases differ based on which proteins/cells are being attacked by your immune system.

Here are some autoimmune diseases you might have come across:

  • Hashimoto’s Thyroiditis
  • Graves’ disease
  • Type 1 Diabetes
  • Rheumatoid Arthritis
  • Psoriasis
  • Celiac Disease
  • Crohn’s Disease
  • Lupus
  • Narcolepsy
  • Ulcerative Colitis
  • Multiple Sclerosis
  • Guillain-Barré Syndrome
  • Hidradenitis Suppurativa
  • Alopecia Areata
  • Autoimmune Hepatitis
  • Angioedema (what I have)

What Causes Autoimmune Diseases?

The science is still a bit fuzzy on all of the possible causes. However, I’m looking forward to reading Sarah Ballantyne’s book, The Paleo Approach, to get a clearer picture of what’s going on. In any event, one likely possibility is that certain foods we eat can cause our gut to “leak.”

Our intestines are lined with epithelial cells that are designed to keep certain substances out of our body (i.e., they have to remain in our intestine and not pass through the intestinal walls) and to allow other substances in (e.g., certain nutrients). However, certain foods in our diet (in addition to certain genetic predispositions) may cause these epithelial cells to lose their tight structure and thereby open up a gap in the intestinal wall.

Bacteria and dietary antigens could then pass through these gaps, thereby causing our bodies’ immune system to attack them. It’s generally a good thing that our immune system attacks foreign substances (like bacteria) that make it into our bloodstream, since that’s how we fight off illness and infection.

However, the immune response caused by that reaction can also have adverse effects, especially if our immune system is continuously fighting off foreign invaders. One of the main adverse effects is that our immune system often starts attacking other parts of our body, rather than just the foreign invaders. And that’s when an autoimmune disease is born.

What is the Paleo Autoimmune Protocol (AIP)?

The Autoimmune Protocol was original developed by Dr. Loren Cordain and Robb Wolf (see the “Autoimmune Caveat” in The Paleo Solution) as a variation of the Paleo diet to help those with autoimmune diseases.

The idea is to eliminate foods that can “irritate and damage the intestines of some people”, even though these eliminated foods are on allowed on a typical Paleo diet.

There are variations of AIP (in particular, Sarah Ballantyne has come up with a stricter version of AIP), and I’ve drawn up a detailed chart below of the allowed and not allowed foods on AIP, noting the variations.

However, remember that AIP is an eliminate-and-then-reintroduce diet! So, the idea is to eliminate all foods on the “not allowed” list for at least 30-60 days (30 days is generally suggested by most people, but some people do 60 days to make sure – Robb states “a month or two” in his book), and then to re-introduce one food at a time to see how your body reacts.

The idea behind the eliminate-and-then-reintroduce approach is that your body reacts badly with certain (but probably not all) of the “not allowed” foods. However, you won’t be able to tell which ones you react badly to unless you first eliminate all of them very strictly for the 30-60 day period. Eileen from the Phoenix Helix has written a great book on how to reintroduce foods on AIP – you can find her book here.

How does AIP differ from Paleo?

For the most part, the 30-60 day elimination component of AIP is a stricter version of Paleo (so you do a pure Paleo diet, and then just eliminate the additional “not allowed” foods for AIP).

Then you spend a few weeks reintroducing the “not allowed” foods back into your Paleo diet.

After you’ve tried to reintroduce all the “not allowed” foods back into your Paleo diet, you will keep doing the Paleo diet and keep eliminating any of the foods that caused you problems when you tried to reintroduce them. For example, if your autoimmune condition worsened when you reintroduced eggs back into your diet after the 30-60 day elimination period, then you would need to keep eggs out of your Paleo diet always even though most people on a Paleo diet eat lots of eggs!

Does AIP work?

I haven’t seen any scientific studies proving the efficacy of AIP, primarily because the concept is relatively new and there’s not a lot of funding for this kind of research. On the other hand, the anecdotal evidence suggests that it works quite well. In fact, Sarah Ballantyne states that AIP “is appropriate for everyone with diagnosed autoimmune disorders or with suspected autoimmune diseases.”

Who Should Try AIP?

Based on the number of people who have emailed me about their autoimmune conditions, I think most people find just sticking to a very pure Paleo diet helps with their conditions. In particular, I’ve heard from a lot of people who have improved their Rheumatoid Arthritis with just a Paleo diet (without attempting AIP).

However, even for those people, a Paleo autoimmune protocol may improve their autoimmune condition even more (read Eileen’s story comparing how much better her Rheumatoid Arthritis got on AIP than on the GAPS diet and Tara’s story on how she had to modify her Paleo diet to improve her Hidradenitis Suppurativa).

And for those people (like me) whose autoimmune conditions don’t improve with Paleo, trying AIP is definitely an option to consider! The main downside to AIP is that it is very restrictive, and you have to be very strict during the entire period or you’ll risk going to all that trouble for nothing.

So, if you’re considering doing AIP, make sure to give yourself at least 60 days to test it out (30 days elimination followed by 30 days reintroduction period). Because the diet is so restrictive, it’s best to ensure you don’t eat out at all (or have to travel far) during that period. This has been my biggest deterrent to trying AIP so far (I seem to be traveling all the time!).

Also, be prepared to face the fact that AIP is TOUGH! I’ve always recognized that AIP is tough. I personally have a hard time imagining life without most of the spices I cook with (most of which are nightshades – for a whole list of nightshade foods, click here). To that end, reading Eileen’s and Melissa’s accounts have made it all the more real for me.

Common Mistakes on AIP

There are 2 common mistakes that people make on AIP (and also on a normal Paleo diet!):

  1. Thinking You Only Need to Change Your Diet And Nothing Else.
    Most people think the Paleo autoimmune protocol as well as regular Paleo is just a diet. Stress, lack of sleep, and lack of exercise (or way too much exercise for some people) are huge components of AIP that many people miss – in fact, I’m really glad Sarah Ballantyne emphasizes these often forgotten components in her book!
  2. Eating Allowed Foods that You’re Sensitive To.
    Even if a certain food is permitted on AIP, you might still be sensitive to it (e.g., coconut products). So, if you know or suspect there’s something else you should be avoiding, then just treat it as a “not allowed” food and reintroduce it after the elimination period.

I’m on week 3 now and I think it’s helping with some issues.


    Thanks Alice – that’s great to hear!


Hi, I am starting week 4 now and I am still flaring up really badly, I’m not sure if there is something I am missing, let me just make sure with you, is black pepper and white pepper allowed?


    Black and white pepper are typically allowed on AIP, but Sarah Ballantyne suggests eliminating them initially just in case.


I can’t believe you left multiple sclerosis off your list of autoimmune diseases! One of the most well known cases of AIP helping relieve autoimmune disease is Dr. Terry Wahls use of AIP! I see this as a serious omission! You really should educate yourself about the phenomenal Dr. Terry Wahls!


    Hi Jeanne – you’re right I did miss that off the list by accident. I’m familiar with Dr. Terry Wahls and have heard her speak before. She is quite phenomenal, and I’ve recommended her work to many readers. Thanks for spotting that omission.


🙂 Great article!
I am at week 8 – I have never felt better in my life! I also avoid some ‘AIP Approved’ foods (coconut, some FODMAPS) due to known sensitivities. It is hard, but it is SO worth it! I am going to commence food re-introduction this week, slowly slowly, and fingers crossed I will be able to safely re-introduce some foods to my diet! 🙂


    Thanks Korine – that’s fantastic to hear!

    HS stinks

    Korine, that’s wonderful to hear! I’ve struggled with stage ii hs for 10 years. I’m committed to making a drastic change but can’t seem to find a recipe guide for restrictive aip living. May I ask what the heck you ate for the past 8 weeks? In regards to your diet, what’s a typical day look like for you?

      Lisa A in Maine

      I found a free 2 week meal plan complete with shopping lists and recipes by Mickey Trescott here: (Just had to subscribe to her free email newsletter)

      I will be just starting this plan this coming weekend – trying to halt my Hashimoto’s symptoms… wish me luck!


Hi, I am so thankful to have found your site!
I suffer with Fibromyalgia, severe anemia and seriously depleted B12 due to an inability to absorb it. I am very keen to try the AIP and have tried to access your wonderful list, but when I click the link, I am unable to input my e-mail address as the link is off the page and I can’t seem to realign it properly. Is it possible to e-mail it to me? Thank you!


    Thanks – emailed to you!


I’m just 5 days in and ecstatic!!! I have celiac and the last 5 months had nonstop migraines! Life had become unbearable. I started paleo in January, it helped but still was having migraines. I was trying to decide if I should do a Whole30 or AIP. That night I had some chicken curry (with nightshade spices) and woke up with headache….so I went with AIP! Not only is the migraine gone I feel like a cloud has lifted and I’m seeing the sun for the first time in memeory! I didn’t know I could feel this good!

Big thanks to ALL the pioneers in AIP!


    That’s absolutely fantastic Cinda!


Your article is great. This is a terrific summary of Sarah Ballantyne’s book!
I started gradually, about 2 months ago, and have been purely AIP for 3 weeks. I’ve since discovered I have a sulfite sensitivity. Eliminating the processed foods is obvious, but what about the foods with natural sulfites? How do you suggest I handle that?
Thank you.


    Hi Margaret, I’m afraid I haven’t read much about sulfite allergies, but this list seems decent with sulfite contents: . I suspect that the first step is to see what amount of sulfites you can tolerate, and then to cut out the foods above that amount. A nutritionist may be able to help you better with developing a plan.


      Thank you!


Hi, I am trying this because of increasing poorer control of my RA; the problem is along with multiple other drugs I need the NSAID at this time… would you recommend still trying this until I hopefully can wean it down and off?


    Hi Denise – I’m sorry but I can’t provide any medical advice as I’m not a doctor. It would be best to consult with your doctor about that issue.



I stopped my Plaquenil and methotrexate injections to fast for 15 days on the master cleanser. The swollen tenderness and heat from inflammation went away in a couple days as well as morning stiffness. I felt normal the rest of the duration. I was leading into AIP when my Dad visited and we went out to eat. I lost composure and cheated. The next day the pain returned. Just like that. So now I’ll lie to my specialist today about taking the drugs. Why lie? It’s my body. So, it’s a personal choice. The drugs cause me a lot of GI issues that cannot be avoided. If I’m trying to heal my gut then no drugs for me. I’m back on the AIP and will repost if you’re interested. BTW I’m a 34 male diagnosed with severe RA here in Calgary, AB.


    Hi Luke, Just wondering how your AIP progress has gone. I am female, early 20s diagnosed with RA and put on exactly what you were- Plaquenil & Methotrexate! I absolutely hated taking them and their side-effects and stopped the meds and am now trying the AIP. I’d love to talk to you about your progress. Thanks!


Hi Louise! A friend recommended your site and I think it’s got some great information and yummy looking recipes! I’ve signed up twice now for your AIP food list PDF but still haven’t got it. Not sure what’s wrong. Could you please email it to me? Thanks 🙂


I have a number of Auto-immune issues including Sjogrens and MS. I have been eating according to AIP for seven months, not a single “cheat”. I reintroduced coffee, eggs, and tomatoes/jalapeños without incident.

My chronic insomnia has completely turned around, joint pain virtually non-existent. The symptoms most problematic – balance, memory, fatigue – have not improved, but I am grateful for the improvements I have

Jill Helman

Hi! I was recently diagnosed with HAE, hereditary angioedema type 3. Would love to get in contact with you. Will you please email me? Thanks!



I have IgA nephropathy. It is an autoimmune disease as well. I am wondering if this approach would help.

    Ancestral Chef

    Hi Jennifer – I haven’t personally come across anyone trying the autoimmune protocol for that condition, but there does appear to be a lot of successes for various autoimmune conditions.


Hi Louise, thanks for sharing all your great recipes, knowledge and experience. I just love getting your email!

I’ve been on Paleo for about 6 months, and eliminated night shades for the past 4 of those. I am feeling relief of some symptoms but haven’t lost ANY weight and I have a LOT to loose. I know I’m still eating foods I’m sensitive to (had allergy testing done, and am not “allergic” to anything, much to my surprise – so they are all sensitivities, but the good news is that those MAY go away once intestinal healing has occurred.) Sarah’s list that you shared helps a lot in terms of knowing what to eliminate next. Just wondering: Do I need to eliminate cacao – which is different than cocoa, as well? Much thanks!

    Angel FNP

    Cacao is a bean. Cocoa comes from cacao beans. Check online. I am not certain how you are using the cacao.

    Professionally speaking, adipose (fat) cells can hold inflammatory chemicals for quite a long time, so healing can be slow as weight loss can be. I have spoken with many people that find that losing weight is challenging, esp if they have some chronic illness, which much of the time, inflammation is at the root of it . If you ARE eating foods that you are sensitive to, this will continue to create inflammation in your body on some level, especially in the gut.

    If you have time, you might want to consider reading about the gut brain. There are many good books that explain about the relationship of food sensitivities, inflammation, and how it affects your intestinal healing, and the “gut brain”, which is where more than 70% of your immune modulation occurs.

    Best of luck on the Journey.

Barbara Flowers

I have not been diagnosed with an autoimmune disease, however in 2013 I found I was sensitive to several nightshades so eliminated them and have not been successful in reintroduction. My sensitivity is extreme to potatoes and eggplant with severe debilitating gastric upset. Tomatoes and peppers cause inflammation in my joints ending in gout. I dearly miss tomatoes and peppers! I appreciate articles like this as I always learn more. Thank you!

Tezeta Solomon

Hi! Loved this article, I recently moved to Ethiopia and realized I need to go AIP to help my HS condition which has gotten way worse since being here. Almost all of Ethiopian dishes are not allowed foods for AIP, this it’s a struggle here, but I’m not giving up! If you can please send me the PDF list, I will greatly appreciate it. Thanks!



just wondering is kelp noodles ok on aip?

thanks for a great site!


Thank you, Louise, for all this great info. I just came across it today, and am feeling hopeful that a pure paleo diet, or the autoimmune protocol might help me. I have autoimmune thyroid ( both hashi’s and graves, which i’m told is rare), frequent migraines and possible ms. Are there online forums, other than facebook, where people like me could find support as they attempt to heal using a paleontologist approach?
Thank you so much again!

    Louise Hendon

    Both PaleoHacks and Mark’s Daily Apple have forums you could check out Patti.


Just found this article. My husband was diagnosed with a blood clot in his head early this year and was put on blood thinners. He then had an autoimmune response to the medication and was hospitalized for a week, unable to hold a cup of water. That was the start of our AIP journey. Since switching to an AIP diet, he has lost 70 lbs. and significantly reduced inflammation. It’s been a difficult adjustment and a lot of times, people just don’t understand. This will be helpful in explaining AIP and teaching family members about his new lifestyle.


What has been your knowledge to the effects of the AIP and alopecia which is a autoimmune disorder. And also how would you suggest reintroducing foods back into your diet if your faced with the slow progress of losing your hair with alopecia areta.

    Louise Hendon

    Hi Wil – I’m sorry I’m not familiar with alopecia. You could try asking Sarah at about it.

    I would personally look into testing to see what could be the root cause – there may be more things happening in the body that you don’t know about that could be causing an AIP illness or making it worse.


I wanted to cry reading this… I have had angioedema and uticaria for 12 months (have high ANA marker as well). I am going insane, with no diagnosis from 4 different doctors. I started accupuncture with some success. This post gave me a little glimmer of hope again, thank you SO much. I am starting API tomorrow. I am going to find the cause, even if all my doctors refuse to think outside of their medicine cabinet.

    Louise Hendon

    Hi Sara! I’m so glad it’s given you more hope. I’ve personally found the following to help my angioedema the most: 1) getting at least 8+ hours sleep per night, 2) de-stressing, 3) better mindset (not getting really upset about anything), 4) eating well and getting lots of nutrients (ie at least a Paleo diet). I’ve been off all antihistamines for over a month now and haven’t had any outbreaks at all (I used to get it several times a week if I didn’t take antihistamines)!! So there is definitely hope 🙂



I’m suspected to have candida overgrowth leading to leaky gut syndrome and rheumatoid arthritis so I’m embarking on a journey to recover through AIP. Can I please have the pdf list? I’ve subscribed with the link above but I guess it’s not working.



    Louise Hendon

    Hi Jasmine – I just sent it to you again, but our system shows that it was sent to you earlier too. I suggest checking in spam as sometimes it gets sent there 🙁 Let me know if you got my new email.

Anne Flynn

Thanks for wonderful article. Ready to strat AIP as soon as possible.
I have Hashimoto’s and extreme skin rashes. I’ve been working with a naturopath for 6 months but still miserable! I’ve eliminated gluten (for 3 years), dairy, soy, and egg (6months). Looks like I may need the AIP to finally heal.
So hard to find a time with no travel!


I would love the AIP list, I tried to print it but would not print always comes up error on page. If you could please send to my email. Thanks so much what a great site!! thanks

    Louise Hendon

    Thanks Jeannine – it’s been sent to you. Let me know if you don’t get it!
