Tricky AIP

Are there any foods that make you go “hmmm” while following the AIP? I decided it was time to start compiling answers to these often confusing foods all in one place. Read on to get all the deets on “tricky” AIP foods. And, if you have ideas for future posts about other foods you aren’t sure about, leave me a comment. We’ll try to clarify and clear up the mysteries!

Coffee and Chocolate

Most people know that coffee and chocolate are eliminated initially on AIP, but the “why” is a source of confusion. It is not because they are “beans” and legumes are out. Coffee and chocolate are misleadingly referred to as beans, but they are actually seeds. Seeds contain protective compounds that can be awfully tough on our systems. It is also not because of caffeine content. While caffeine consumption is best kept low on AIP, it is not the basis for food eliminations.

Verdict: Coffee and chocolate are NOT elimination-phase legal.


Okay, before we get started on this one, let it be known that this is a nit-picky area of the protocol. A history lesson could be useful here. Back in the way back, when AIP was first coming on the scene, vanilla was not mentioned as a food to eliminate, it just rested in a no-man’s land. In fact, some of us who started the protocol in those early days never eliminated vanilla at all, as it was not mentioned. Later, it was defined by Dr. Sarah Ballantyne (in her book, The Paleo Approach) that vanilla bean, along with other fruit or berry-derived spices, should be avoided during elimination phase, because the seeds of these plants are ground up with the spice. This allowed for gluten-free vanilla extract (where the alcohol will cook off, so best for hot-preparation recipes) or grain-free, sugar-free vanilla powder (which works for cold preparation recipes). In some cases, those in the AIP community use the seeds scrapped from the inside of a vanilla bean, since they can be consumed without chewing them, like many of the seeds in elimination-friendly fruits (more on that below).

Verdict: Gluten-free vanilla extract (alcohol will cook off), grain-free, sugar-free vanilla powder, and possibly fresh vanilla bean scrapings are elimination-phase legal.

Fruits & Vegetable-like Fruits with Seeds

This is often an area of concern for folks trying to carefully comply with the elimination phase of AIP. Foods like berries, kiwis, watermelon, pomegranate, cucumber, zucchini, and even bananas or plantains are not a problem, mainly because we don’t really chew these seeds. Dr. Ballantyne does note in The Paleo Approach that if you aren’t experiencing obvious improvement using AIP, you might consider these small seeds. Why consider them? Because, they do contain small amounts of protease inhibitors. Proteases are a group of many kinds of a digestive enzyme that helps us digest and break apart proteins. For a host of complex reasons, very sensitive individuals might consider this with even the consumption of very small seeds, like those found in the above mentioned foods, if they are having trouble improving their health on the protocol.

Verdict: Fruits and vegetable-like fruits with seeds are elimination-phase legal.

Beans, Peas, and Other Foods from the Legume Family

There’s actually a lot to cover in this category, so let us take it one at a time.

  • Legumes with Edible Pods — This includes green beans, scarlet runner beans, sugar snap peas, snow peas, peas, etc. Like vanilla, when AIP first came on the scene, this was not a specific elimination and was very much viewed as a gray-area. Later, Dr. Ballantyne clarified that while generally not a problem, initial elimination with early reintroduction was wise, due to lectin content. If you want some clarity on lectins, check out this article.
    Verdict: Legumes with edible pods are NOT elimination-phase legal.
  • Carob — Carob is a legume with an edible pod, BUT it gets a pass. Why? Because we only consume the ground up pod, not the seeds, as a chocolate substitute. If carob seems to bother you, it may be the fact that it is a high-FODMAP food and smaller servings may work better for you. It is a food that is recommended in The Paleo Approach to consume in moderation anyway.
    Verdict: Carob is elimination-phase legal.
  • Jicama — Jicama is part of the larger legume family as well, however, like carob, it gets a pass. Why? Because we only consume the tuberous root.
    Verdict: Jicama is elimination-phase legal.
  • Rooibos Tea — Again, rooibos is part of the larger legume family, but gets a pass. In this case, we only consume the leaves. It should be noted that, like carob, it is recommended to consume rooibos tea in moderation.
    Verdict: Rooibos tea is elimination-phase legal.
  • Bean or Pea Sprouts — Surprise, these are not okay. The problem is that concentrations of lectins are still pretty high in the sprouts.  You might think this would apply to rooibos too, but mature leaves are less problematic.
    Verdict: Bean or pea sprouts are NOT elimination-phase legal.

Mucilaginous Foods

This category includes aloe vera, slippery elm, chia, and flaxseed, all of which produce thick, mucous-like gels. Dr. Ballantyne recommends a great deal of caution with these foods for a number of reasons; they can hinder digestion, in some cases are high in phytic acid or high in phytoestrogens, and are shown to modulate the immune system. All of these effects can be problematic for those with autoimmune disease.

Verdict: Aloe vera, slippery elm, chia, and flaxseed are NOT elimination-phase legal.


This one confuses lots of folks. Peppercorns come from trees or shrubs and are their fruit, hence why they are removed like other fruit and berry-based spices. Black, white, and green peppercorns all come from the same tree (color is the result of harvesting or treatment processes), while pink peppercorns can come from a different tree family. The heat from this spice is not the same as the heat from nightshade peppers — it is from a chemical called piperine, not capsaicin. In The Paleo Approach, it is recommended to be cautious with pepper and eliminate initially, with a likely early reintroduction. In the early days of AIP, it was one of those foods that was not initially eliminated, but later clarified.

Verdict: Peppercorns are NOT elimination-phase legal.

Sweet Potatoes

Folks, let’s put this one to bed…sweet potatoes are not the same as white potatoes. It is not part of the nightshade family, unlike the white potato, which is a nightshade. Sweet potato is a starchy root veggie, different from a yam, but both very nutritious. The flesh can be beige, white, red, purple, yellow or orange, but again, flesh color, even white or purple, does not mean it is part of the nightshade potato family (which we eliminate).

Verdict: Sweet potatoes (and their often mistaken cousin, yams) are elimination-phase legal.


Okay, this is going to ruffle feathers, but let’s clear this one up. Coconut is really different from tree nuts. The coconut palm is not technically a tree, it’s related to grass. All the tree nut allergy folks should now try to calm down (everyone who is trying to get offended, breathe deep…I am in no way insinuating a tree nut allergy is not life-threateningly serious). Dr. Ballantyne recommends that we use moderation with whole coconut and coconut products, due to phytic acid and very high inulin fiber content. This moderation caution doesn’t apply to coconut oil which doesn’t contain phytic acid or inulin fiber.

Verdict: Coconut is elimination-phase legal.


Stevia is a sugar substitute extracted from the leaves of a plant. Lots of folks in the larger health and wellness community looooove stevia and trumpet its amazingness far and wide. Guess what? It can mess with our hormones in a big way, which is a huge problem for those with autoimmune disease. The science here is complex, but if you want all the nitty-gritty, check out this article.

Verdict: Stevia is NOT elimination-phase legal.

Onions, Garlic, and other High-FODMAP Foods

Certain foods can be high in particular kinds of sugar (the acronym FODMAP stands for the chemical names of those sugars) that, in the case of a bacterial overgrowth in the small intestine (SIBO), can be fermented by the bacteria. This causes incredible bloating, pain, nausea, flatulence, belching, diarrhea, or constipation for those with an overgrowth. Onions and garlic are among the highest-FODMAP foods and are also among the most commonly used on AIP, because we rely so much on them for flavoring. Despite this, we don’t eliminate these foods, because SIBO is not an issue across the board for those with autoimmune disease. IF you have autoimmune disease AND SIBO, it can help to temporarily eliminate or reduce FODMAP consumption, because it helps control symptoms. (Note that controlling symptoms is not the same as treating the bacterial overgrowth. SIBO cannot be treated with diet alone.)

Verdict: High-FODMAP foods are elimination-phase legal.


For those with diagnosed Celiac disease or gluten-sensitivity (all autoimmune disease has a very high association with gluten-sensitivity), there are some foods that your body may mistakenly identify as being the same as gluten and begin producing antibodies to that food. The list of the common foods associated with “mistaken identity problem” was developed by Cyrex Labs, which also has a test to help you identify if you have cross-reactivity to any of them. The standout food on the list that many people still consume during the AIP elimination phase is tapioca (the same thing as cassava or yucca). Much like the FODMAPs above, we don’t eliminate tapioca, because cross-reactivity is not an issue across the board and even if you do experience cross-reactivity, it may not be to tapioca. Additionally, some people may not tolerate cassava well due to its high-starch content, but not necessarily because their body is cross-reacting to it. If you aren’t experiencing obvious improvement using AIP, you might consider eliminating cassava to see if you do better or being tested for cross-reactivity. This article has tons of further detail.

Verdict: Cassava is elimination-phase legal.

Evening Primrose Oil

This oil is made by cold-pressing the seeds of a flowering plant. It has many therapeutic uses, most centered around female hormone balancing. However, as it is derived from a seed, it is removed during the elimination-phase of AIP. (Caution! If you’ve been prescribed Evening Primrose Oil, it is best to consult with your doctor, before eliminating it. There are possible substitutes, but those decisions should be made with a professional.)

Verdict: Evening Primrose Oil is NOT elimination-phase legal.


Tigernuts are not nuts. They are tubers which are dried after harvest and then used in a variety of ways (from “milks” to flour). They are very high in resistant starch (starch our bodies can’t digest, sometimes called “prebiotic”), which makes them a food that doesn’t work as well for some folks.

Verdict: Tigernuts are elimination-phase legal.


Pectin is a fiber found in fruits, especially apples. It is often used for thickening jams for canning and can be used in baking as a binder. It is best in moderation on AIP, because the extra fiber can be hard for some folks to digest.

Verdict: Pectin is elimination-phase legal.

Baking Soda, Baking Powder, and Cream of Tartar

Baking soda is also called sodium bicarbonate. It can be both mined and produced. Baking powder is a mixture of baking soda, an acid (usually cream of tartar), and corn starch. Both are used to make things rise and expand in baking, but baking soda is alkaline, while baking powder has some acid. Obviously, baking powder is removed on AIP due to the cornstarch, however, simply combining baking soda and cream of tartar creates baking powder.

Verdict: Baking soda and cream of tartar are elimination-phase legal, but baking powder is NOT.

Caffeinated Tea (Green or Black)

AIP is a coffee-free (see above), but not a caffeine-free protocol. Green and black teas can be consumed, but due to the caffeine it’s generally advised to drink them earlier in the day and in moderation. It is also important to read labels carefully, as many teas have soy lecithin or other additives that are avoided on AIP. If adrenal fatigue is part of your health picture, you’ll want to work to eliminate caffeine entirely.

Verdict: Caffeinated teas are elimination-phase legal.

    For me, the main controversial point is meat. Is there research and evidence that meat does not make the condition worse in autoimmune diseases?

  • Tanya says

    Is milk thistle seed okay with AIP?

    • Mickey Trescott says

      Hi Tanya, all seeds are out in the elimination phase.

  • eugenia says

    what about ammonium bicarbonate as raising agent? is this AIP?

  • Aaron says

    Hi Mickey, I know that broccoli sprouts are AIP elimination compliant, I also am aware that seeds are not. What about seeds leftover from sprouting broccoli seeds. Before I started AIP I began growing my own broccoli sprouts for the high sulforaphane content but there are unsprouted seeds and or seed shell remnants in with the sprouts that would be extremely time consuming to pick out and remove. Would it be ok to consume these with the broccoli sprouts? – Thank you

    • Mickey Trescott says

      Hi Aaron! The sprouts are in, but the leftover seeds are out. You can simply cut them off above the seed and consume the green part on AIP. And remember, AIP is not “forever,” so you might find they are just fine during reintroductions. Hope it helps!

  • Catherine says

    This may be an odd question. But what do you mean by “not elimination phase legal”
    I am dyslexic. And thank goodness for spellcheck and grammar check, but I really do not understand this statement.

    Thanks in advance


    • Mickey Trescott says

      Hi Cate! Angie means that the food in question is avoided during the elimination phase.

  • Jessica says

    Hi! Thank you for the awesome list. Is kuzu root AIP compliant?

    Thank you!

    • Mickey Trescott says

      Hi Jessica, yes kuzu is allowed in elimination!

  • Alicia Horn says


    Is lactic acid, citric acid or absorbic acid AIP compliant? I see these in a lot of otherwise AIP compliant foods.


    • Mickey Trescott says

      Hi Alicia!
      It depends on the source – sometimes these acids can be made from corn, sugar, or dairy, so it is best to check if you suspect you are extremely sensitive.

  • Mary says

    Hi Ally,
    Are dried golden berries AIP compliant?
    Thank you,

  • Diana says

    Thank you for all you great information. I wanted to add a warning about cassava. Sadly, it is usually very high in lead, as are most cassava-based products you will find out there. When I discovered it about six years ago, I thought it was amazing, but two years later I tested off the charts for lead toxicity. After much research and some great help from the Lead Free Mama, I discovered it he culprit was most likely cassava. I wanted to put that out there so you all don’t have to learn the hard way like I did.
