What is the AIP? A complete guide to the autoimmune protocol


What is the Autoimmune Protocol?

Autoimmune protocol, autoimmune paleo or AIP for short is an elimination diet designed to heal leaky gut and reduce inflammation with the purpose of reversing symptoms caused by autoimmune disease. It is also used so that one can find out which foods are the aggravating their symptoms, causing inflammation and essentially making their autoimmune disease worse.


What is an Autoimmune Disease?

Essentially an autoimmune disease is when your immune system attacks healthy cells in your body. Yup, your body is attacking itself. For people with Hashimoto’s it’s the thyroid, multiple sclerosis the nerves, arthritis the joints and so on.

There are more than eighty autoimmune diseases, they are notoriously difficult to diagnose, and many people with autoimmunity live with their diseases for decades without getting much help from their doctors. This is why the AIP community is so prolific. Vast, growing, and very active. People in forums, blogs and communities helping each other navigate this world of healing through diet a lifestyle changes. 



How Does The AIP Help?

The autoimmune protocol eliminates specific foods based on their levels of antinutrients and gut permeability. The list of food to exclude seems extensive, but remember, you need to eliminate any and all possible triggers foods. All the foods on the list have the potential to irritate the digestive system, damage the gut, and, when leaky gut is present, even seep through the intestinal wall and trigger inflammation.


Now, let’s not VILIFY any foods. The foods OMITTED are POSSIBLE irritants. We will discuss the details later on. These foods are not bad or good, it’s just science. Pretty much everything we eat has the potential to harm up and heal us. Some more than others. This elimination diet is meant as a baseline, a template for you to work with to find out what works for you.

How can you live symptom-free, pain-free, inflammation-free? Find that sweet spot! Then you can start testing food to add back into your diet.

That’s right, elimination diets aren’t meant to last forever. Even the autoimmune protocol…  It’s a TOOL, to learn your trigger foods so you an avoid them, and go on living your life. The more variety of foods in your diet the better!

How to Start The AIP

First, choose your approach. Some folks rip the band aid off. They go head first, cold turkey. Some folks need to ease into it. I took me several months to do it. I did a Whole30 first. Then I stuck to a paleo template. Eventually, I committed. I got rid of all non-compliant foods. Meal prepped. Bought all the meat and veggies, bone broth etc.

Whichever method you decide… it’s okay. We’re all different. Having information is your greatest tool for success. You will need to prepare all of your meals. Freezer, AIP, meal prep are your new BFF’s. This company sells and delivers frozen AIP meals, and they are good too!

AIP food list


The first medical study on it was conducted last year with patients who had inflammatory bowel disease, and 73 percent saw improvement or remission! Here’s what the researchers said: “Clinical remission was achieved by week 6 by 11/15 (73%) of study participants, and all 11 maintained clinical remission during the maintenance phase of the study. [This] rivals … most drug therapies for IBD.”[1]

I understand that seems impossible, it can be stressful, which is why I am a big proponent of choosing your own start method. My biggest piece of advice is to give yourself time. You won’t see results in a few days or even a few weeks. It takes time to reverse leaky gut!

You have to be patient.

You need to keep a detailed food journal. What you ate, when, how you felt. Also, journal any and all symptoms. It’s the only way to map out the correlations and be sure of the foods that could cause issues.

What to Look For?

Short of an autoimmune flare, you know, your autoimmune disease rearing its ugly head… there are some subtle signs a food isn’t jiving…

A headache, runny nose, fatigue, digestive distress, itchy skin, bloating, gas, burping, hives.

Please note… if you’re already sick with a cold, and you have a runny nose, it’s the cold, not the food. If you are super stressed or overworked… the fatigue is probably that, not the food. Don’t go crazy blaming EVERYTHING on food. You have to be honest with yourself about lifestyle factors.

When To Begin Re-Introductions

The rule of thumb is when your flare free more often than not. Do you feel better? Are you in remission or almost there? It’s really a personal choice.Be honest with yourself. Here is a good resource to help you… 



What are Anti-Nutrients?

Lectins, solanine, saponin: Found in beans, nuts, wheat, and most vegetables with skin and seeds, these antinutrients survive digestion and can penetrate the gut lining.

Gluten: The most difficult-to-digest protein, extremely irritating to the gut.

Tannins: Enzyme inhibitors that prevent the proper digestion of protein.

Oxalates: Found in coffee, sesame seeds, beans, these can interfere with nutrient absorption.

Phytic acid: Found in grains, legumes, nuts, seeds, and coconut, this can interfere with the absorption of minerals and inhibits the digestive enzymes that break down starch and proteins.

Antinutrients are found in all plants; however, many foods, like those allowed on the autoimmune protocol, contain lower levels, and the benefits greatly outweigh any possible, harmful effects, after all, we have to eat something! 

The good news is that there are many ways to further reduce the anti-nutrient content of foods so even though you may not be able to enjoy nuts or seeds now, perhaps after healing leaky gut you can enjoy them sprouted! Look at how our ancestors prepared foods, sprouting, fermenting, soaking; preparation methods which makes foods much easier to digest!

Other foods like eggs and dairy are omitted because these foods easily permeate the gut lining and hitch a ride on the bloodstream causing all sorts of havoc! 


Troubleshooting During the AIP

Are autoimmune protocol compliant foods making your flare? Have you given it at least 3 months and still not seeing results? Here are some other factors to consider….

Insulin Resistance: When your cells no longer respond to the insulin secreted by your pancreas. This can also tax the liver. I think keto is a great tool to improve insulin sensitivity. I have an AIP + Keto Reset HERE.  Or my Keto-Paleo cookbook with over 110 AIP recipes HERE. 

SIBO: Small Intestine Bacterial Overgrowth. You need to starve the bad bacteria in your gut. Take a probiotic. Avoid starchy foods, fruit, garlic, broccoli, cabbage, asparagus and leeks (as well as other AIP non-compliant foods).  More info HERE. 

Low Fodmap: Some folks need to avoid foods high in Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols. Implementing a Low Fodmap would mean to avoid all onion and garlic, most fruit, cauliflower, cassava, celery, taro, juices, fermented foods! More Info HERE. 

Candida: If you’re suffering from thrush or a yeast overgrowth you need to avoid sugars and foods with naturally occurring yeast. On top of the AIP, avoid fruits, sweeteners, berries, pork and tuna. Be wary of vinegar, kombucha, and other fermented foods. 

You may talk to your healthcare practitioner or research and deduce that you may have one of these or many of these issues going on, along with your autoimmunity. Combining the appropriate protocols, the autoimmune protocol ++ is what I like to call it, can be tough as hell, but also very useful. Remember… it’s not meant to last forever! 

Closing Thoughts

Elimination diets, healing diets and protocols are my jam. I have done several and constantly experiment with them as my body heals. I have also been at this for 3 years and while I have seen great improvement I am not done. I still can’t eat a lot of things… and I am okay with that. Remember to also work on the emotional side of healing. Do not resent your body, hate it or be angry with it. You need to practice self-love, grace and appreciation for the knowledge and tools at your disposal as you go forward to heal yourself.
