If you're grappling with an autoimmune disease, you may have encountered the Autoimmune Protocol (AIP) diet. This specialized dietary approach aims to alleviate symptoms by restricting common food allergens and inflammatory foods, while emphasizing nutrient-rich options that support healing. The AIP diet is not a weight-loss plan but rather a protocol designed to manage autoimmune conditions.
Understanding the AIP Diet
The AIP diet is a stricter iteration of the Paleo diet, meticulously crafted to address the unique needs of individuals with autoimmune disorders. It operates on the premise that certain foods can trigger inflammation and exacerbate autoimmune responses. By eliminating these potential triggers and focusing on foods that promote gut health and immune regulation, the AIP diet seeks to reduce inflammation and improve overall well-being.
Origins and Purpose
The AIP diet was conceived by Dr. Loren Cordain, a researcher specializing in evolutionary medicine and the dietary factors influencing autoimmune conditions. Dr. Cordain theorized that specific foods could incite inflammation in individuals with autoimmune diseases, and their removal could potentially mitigate these conditions.
AIP vs. Paleo: Key Differences
While the AIP and Paleo diets share similarities, such as emphasizing whole, nutrient-dense foods and excluding processed foods, grains, and legumes, the AIP diet is more restrictive. It further eliminates eggs, nightshades (like tomatoes, eggplant, and peppers), nuts, and seeds, which may trigger immune responses in those with autoimmunity. Additionally, the AIP diet is designed as a phased approach, with the eventual reintroduction of foods after symptom improvement.
The Science Behind AIP
The AIP diet seeks to quell inflammation by temporarily removing potential inflammatory food triggers. This allows the immune system and gut's intestinal barrier to return to a more regulated state, alleviating symptoms and facilitating tissue repair.

Phases of the AIP Diet
The AIP diet unfolds in two primary phases: the elimination phase and the reintroduction phase.
Phase 1: Elimination
This initial phase, lasting from four to six weeks or even a few months, involves eliminating foods, additives, and medications believed to incite intestinal inflammation, disrupt gut microbiota, or worsen immune responses.
Foods to Avoid During the Elimination Phase:
- Grains (especially gluten-containing grains like wheat, barley, and rye)
- Legumes (including beans, peas, lentils, chickpeas, soybeans, and peanuts)
- Nightshade vegetables (such as tomatoes, potatoes, peppers, and eggplant)
- Dairy products
- Processed foods
- Refined sugars
- Eggs
- Nuts and seeds
- Coffee
- Alcohol
Additionally, the use of tobacco and nonsteroidal anti-inflammatory drugs (NSAIDs) should be discontinued during this phase.
Focus on Inclusion:
While the list of restrictions may seem daunting, it's crucial to focus on the abundance of foods that can be included. Vegetables, fruits, fish, grass-fed meats, and organ meats form the cornerstone of the AIP diet. Creative substitutions can also help bridge the gap for beloved foods. For instance, cauliflower can replace rice, and honey can be used in place of processed sugars.
Monitoring and Expected Outcomes:
During the elimination phase, close monitoring of chronic inflammatory symptoms is essential. The goal is to experience an overall improvement in quality of life and a reduction in symptoms as the body begins to heal. If no improvement is observed by the end of this period, consulting a dietitian is recommended to explore alternative strategies.

Phase 2: Reintroduction
The reintroduction phase commences once significant symptom improvement has been achieved. This phase involves systematically reintroducing eliminated foods, one at a time, over a period of five to seven days each. The aim is to identify which foods trigger symptoms and should be avoided long-term, while safely reintroducing those that are well-tolerated.
Reintroduction Strategies:
- Prioritize most missed foods: Reintroduce foods in the order of personal preference and craving.
- Start with beneficial foods: Begin with foods known for their nutritional value and low likelihood of causing reactions.
Reintroduction Protocol:
- Choose one food: Select a single food to reintroduce.
- Initial sampling: Start with a small amount, such as a teaspoon, and wait 15 minutes for any immediate reactions.
- Gradual increase: If no immediate reaction occurs, increase the portion size to two teaspoons and wait two to three hours.
- Normal portion: If still no reaction, consume a normal portion of the food.
- Avoidance period: Avoid the reintroduced food for five to seven days, without introducing any other new foods.
- Monitor for reactions: Observe for any delayed reactions during the avoidance period. If reactions occur, discontinue consumption of that food. If no reactions occur, the food can be fully reintroduced into the diet.
It's crucial to monitor symptoms throughout the reintroduction process, as reactions can sometimes be delayed. Re-trying a food after a year of avoidance may be considered, as food intolerances can evolve over time.
Phase 3: Maintenance
The maintenance phase integrates the knowledge gained from the elimination and reintroduction phases into a personalized, long-term dietary plan. This phase emphasizes personalization, food diversity, and dietary flexibility. Individuals tailor their diets based on their unique triggers and tolerances, allowing for occasional indulgences while maintaining overall symptom control.
Foods to Include and Avoid on the AIP Diet
The AIP diet revolves around a carefully curated list of foods to include and avoid, designed to minimize inflammation and promote healing.
Foods to Include
- Vegetables: A wide variety of non-nightshade vegetables, such as cucumbers, spinach, sweet potatoes, and zucchini. Leafy greens like spinach and kale are nutritional powerhouses, rich in magnesium and vitamin B6, which may help reduce arthritis-related pain.
- Fruits: Fresh fruits like apples, oranges, mangos, strawberries, bananas, and blueberries. Colorful fruits provide a diverse range of phytonutrients with antioxidant, antimicrobial, antiviral, and anti-inflammatory benefits.
- Minimally processed meats: Grass-fed beef, fish, seafood, organ meats, and poultry. Animal fats like duck fat, lard, and tallow, as well as fatty fish, are encouraged. Organ meats, such as liver, kidney, and heart, are particularly nutrient-dense, providing essential vitamins and minerals for immune function.
- Healthy fats: Avocado oil, olive oil, and coconut oil. Coconut oil is a good choice for cooking due to its high lauric acid content, which has been shown to help with viral infections and boost the immune system.
- Natural sweeteners: Honey, agave, and maple syrup (in moderation).
- Herbs and spices: Ginger, garlic, cumin, coriander, oregano, salt, and black pepper. Many herbs and spices possess medicinal properties, such as cinnamon's ability to improve insulin sensitivity and turmeric's potent anti-inflammatory effects.
- Fermented foods: Non-dairy-based and non-nightshade-based fermented foods like sauerkraut, pickles, kimchi, and kombucha. Fermented foods are rich in probiotics, which help improve gut health by balancing the good bacteria in the intestines.
- Glycine-rich foods: Bone broth, organ meats, tendons, ligaments, skin of animal meats, seafood, dried seaweed, spinach, and watercress. Glycine is an amino acid used to make glutathione, a powerful antioxidant that protects the body from oxidative stress, and has anti-inflammatory effects.
- Herbal teas: Most herbal teas are gluten-free and decaffeinated, making them a safe and soothing beverage choice.
Foods to Avoid
- Grains: Rice, oats, wheat, barley, rye, quinoa, corn, and any products made with these ingredients, like cereal, pasta, bread, and baked goods.
- Legumes: Black beans, kidney beans, lentils, peas, chickpeas, soybeans, peanuts, and products made with these ingredients, like tofu, peanut butter, and hummus.
- Nightshade vegetables: Tomatoes, potatoes, peppers, eggplant, tomatillos, jalapenos, and spices made from these vegetables, like cayenne pepper or paprika.
- Dairy products: Cow's milk, goat's milk, or sheep's milk and any products made from these, including ice cream, cheese, butter, and any dairy-based protein powders or supplements.
- Eggs: Whole eggs, egg whites, or foods containing these ingredients.
- Processed foods: Deli meats, hot dogs, sausages, canned vegetables, canned soups, microwave meals, packaged snacks, and processed vegetable oils like canola, corn, or soybean oil. Seed oils like canola, soybean, sunflower, and safflower are not allowed on AIP.
- Refined sugars: Sweets, sodas, candies, chocolate, cane sugar, corn syrup, brown rice syrup, etc.
- Nuts and seeds: All nuts, seeds, and foods made from these ingredients, including flours, butter, or oils, cocoa, and seed-based spices like coriander, cumin, fennel, mustard, and nutmeg.
- Certain beverages: Coffee and alcohol.
- Food additives: Artificial sweeteners like stevia, saccharin, or xylitol, food colorings, emulsifiers, and thickeners.
Addressing Chickpeas on the AIP Diet
Chickpeas, while a nutritious legume, are not permitted on the AIP diet due to their potential to trigger inflammation in individuals with autoimmune conditions. Chickpeas, along with other legumes, contain compounds like lectins and saponins, which can be problematic for individuals with autoimmune conditions.

AIP-Compliant Chickpea Substitutes
While chickpeas are off-limits, there are creative ways to mimic their texture and flavor in various dishes using AIP-compliant ingredients. Butternut squash, for example, can be roasted, mashed, or pureed to create hummus-like dips.
Benefits of the AIP Diet
The AIP diet offers several potential benefits for individuals with autoimmune disorders, including:
- Managing autoimmune disorders: Studies suggest that the AIP diet can help reduce symptoms and improve quality of life for individuals with rheumatoid arthritis and inflammatory bowel disease (IBD).
- Improving overall health: The AIP diet promotes gut health by encouraging the consumption of fermented foods and eliminating potential gut irritants. It may also help reduce inflammation and improve working memory.
Research and Studies
Current research on the AIP diet is primarily focused on its impact on individuals with inflammatory bowel disease (IBD) and Hashimoto's thyroiditis. Studies have shown that following the diet can improve quality of life, reduce IBD disease activity, and lower inflammation markers. However, further research is needed to confirm these results and explore the AIP diet's efficacy for other autoimmune disorders.
Tips for Success on the AIP Diet
Embarking on the AIP diet requires careful planning and commitment. Here are some tips to maximize your chances of success:
- Meal planning and preparation: Create a weekly meal plan to ensure you have AIP-compliant options readily available. Batch cooking can save time and effort by preparing large portions of food in advance.
- Seek professional guidance: Consult a registered dietitian or nutritionist specializing in autoimmune conditions for personalized support and guidance.
- Find support groups: Connect with others following the AIP diet for shared experiences, recipe ideas, and emotional support.
- Track your progress: Keep a journal to monitor symptom changes and identify trigger foods.
- Stay motivated: Focus on the positive aspects of the diet, such as improved energy levels and reduced symptoms.
Modified AIP Diet: A More Flexible Approach
For some individuals, the strict elimination phase of the AIP diet can be challenging to maintain long-term. The Modified AIP diet offers a more flexible approach while still adhering to the foundational principles of reducing inflammation and promoting gut health.
Key Features of the Modified AIP Diet
- Personalized eliminations: Identify and eliminate foods that specifically trigger symptoms for you.
- Gradual reintroductions: Systematically reintroduce foods to test your body's response.
- Flexibility: Incorporate certain foods that are excluded from the standard AIP diet, such as white rice and ghee.
