In our peer-reviewed article, we explore the fundamentals of the AIP diet and provide you with a comprehensive understanding of this unique eating approach.

What is the AIP Diet and How Does It Work?

The AIP diet, short for the autoimmune protocol diet, is a therapeutic approach to eating that aims to reduce inflammation and alleviate symptoms related to autoimmune diseases. It is based on the idea that certain foods can trigger immune reactions in individuals with autoimmune conditions, leading to increased inflammation and overall health issues.

Foods to Avoid on the AIP Diet

On the AIP diet, there are specific foods that should be eliminated from your daily intake. These include:

1. Grains and Pseudo-Grains

Wheat, rice, corn, oats, quinoa, and other grains should be avoided as they can contribute to gut irritation and inflammation.

2. Legumes

Beans, lentils, soy, and peanuts are high in lectins and phytates, which can be problematic for individuals with autoimmune conditions.

3. Nightshades

Tomatoes, peppers, potatoes, and eggplants contain solanine and other compounds that may exacerbate inflammation and worsen symptoms.

4. Dairy

Milk, cheese, yogurt, and other dairy products can be inflammatory for some individuals, especially those with autoimmune disorders.

5. Processed Foods

Packaged snacks, fast food, artificial sweeteners, and refined sugars should be avoided due to their negative impact on inflammation and overall health.

Foods Allowed on the AIP Diet

While it has a list of foods to avoid, there are still plenty of nourishing options that you can enjoy. Here are some of the foods allowed on the AIP diet:

1. Meats and Poultry

Grass-fed beef, free-range chicken, turkey, and other lean cuts of meat provide essential nutrients and protein.

2. Fish and Seafood

Fatty fish like salmon, mackerel, and sardines are rich in omega-3 fatty acids, which have anti-inflammatory properties.

3. Vegetables

Non-nightshade vegetables such as leafy greens, broccoli, carrots, and Brussels sprouts are highly recommended for their nutrient density.

4. Fruits

Berries, apples, pears, and other low-sugar fruits are excellent sources of vitamins, minerals, and antioxidants.

5. Healthy Fats

Avocado, coconut oil, olive oil, and animal fats (from pasture-raised animals) provide nourishment and aid in reducing inflammation.

6. Bone Broth

Rich in collagen, gelatin, and minerals, bone broth helps to support gut health, which is crucial for individuals with autoimmune conditions.

7. Herbs and Spices

Turmeric, ginger, garlic, oregano, and thyme have anti-inflammatory properties and can add flavor to your AIP meals.

Benefits of the AIP Diet for Autoimmune Conditions

It has gained recognition for its potential to improve symptoms associated with autoimmune diseases. By eliminating inflammatory triggers and focusing on nutrient-dense foods, it offers several potential benefits, including:

1. Reduced Inflammation

The removal of inflammatory foods helps to decrease overall inflammation levels within the body.

2. Improved Gut Health

By excluding gut irritants and including gut-healing foods like bone broth, the AIP diet supports a healthy digestive system.

3. Enhanced Nutrient Intake

AIP-friendly foods are packed with essential nutrients, vitamins, and minerals, promoting overall wellness.

4. Identification of Food Sensitivities

Following the AIP diet allows individuals to identify specific food sensitivities that may be worsening their symptoms.

5. Support for the Immune System

The AIP diet helps to balance and support the immune system, which is compromised in people with autoimmune conditions.

AIP Diet vs. Paleo Diet: What’s the Difference?

While the AIP diet and the Paleo diet share some similarities, there are key differences between the two approaches. Understanding these distinctions can help you determine which eating plan may be more suitable for your needs.

AIP Diet

It is considered a stricter version of the Paleo diet, with additional restrictions that specifically target foods known to provoke inflammation and immune responses in individuals with autoimmune diseases. It emphasizes the exclusion of certain foods for some time, allowing the body to heal and reduce autoimmune symptoms before gradually reintroducing them to pinpoint any triggers.

In addition to the general Paleo diet restrictions (such as grains, legumes, and processed foods), the AIP diet eliminates nightshade vegetables (such as tomatoes, peppers, and eggplants) and certain spices, nuts, and seeds. While the initial elimination phase may feel restrictive, it serves as a valuable tool for uncovering which specific foods exacerbate symptoms.

Paleo Diet

The Paleo diet, also known as the Paleolithic diet or the “caveman” diet, focuses on consuming foods that our ancestors would have eaten during the Paleolithic era. The premise is to mimic the dietary patterns of our hunter-gatherer predecessors, emphasizing whole, unprocessed foods.

On the Paleo diet, you’ll consume lean meats, seafood, vegetables, fruits, nuts, and seeds. Grains, legumes, dairy, refined sugars, and processed foods are avoided because they were introduced with the advent of agriculture and the rise of modern food processing techniques.

Which Approach is Right for You?

If you have been diagnosed with an autoimmune condition or suspect that certain foods may be triggering symptoms, the AIP diet could be a beneficial starting point to identify and eliminate potential triggers.

On the other hand, if you’re seeking a more general approach to improve overall health and well-being, the Paleo diet may provide a solid foundation by focusing on whole, nutrient-dense foods and eliminating processed options.

Practical Tips for Getting Started with the AIP Diet

If you’re considering embarking on the AIP diet journey, here are some practical tips to help you get started:

1. Educate Yourself

Understand the principles and guidelines of the AIP diet. Familiarize yourself with the foods to avoid and the foods that are allowed.

2. Plan Your Meals

Take time to plan your meals to ensure they comply with the AIP diet. Explore AIP-friendly recipes and create a shopping list.

3. Gradual Elimination

Instead of immediately eliminating all restricted foods, consider gradually removing them from your diet to ease the transition and make it more sustainable.

4. Supportive Environment

Seek support from friends, family, or online communities who understand and can provide encouragement during your AIP diet journey.

5. Experiment and Adapt

Pay attention to how your body responds to different foods during the reintroduction phase. Learn which foods work well for you and make adjustments accordingly.

Maintaining Balance and Sustainability with the AIP Diet

While the AIP diet offers numerous benefits for individuals with autoimmune conditions, maintaining a sense of balance and sustainability is crucial. Here are some important considerations to keep in mind:

1. Individualization is Key

Every person’s body is unique, and what works for one individual may not work for another. It’s essential to pay attention to your body’s signals and adjust the AIP diet according to your specific needs. Some people may find that certain reintroduced foods are well tolerated, while others may need to continue avoiding them. Listen to your body and make choices that support your overall well-being.

2. Focus on Nutrient Density

As you navigate the AIP diet, prioritize nutrient-dense foods that provide a wide range of vitamins, minerals, and antioxidants. These foods will not only support your immune system but also contribute to your overall health. Experiment with a variety of fruits, vegetables, quality proteins, healthy fats, and herbs to ensure you’re meeting your body’s nutritional requirements.

3. Mindfulness and Stress Reduction

While diet plays a significant role in managing autoimmune conditions, stress and lifestyle factors can also impact your well-being. Incorporate stress reduction techniques such as meditation, yoga, or engaging in activities you enjoy. Cultivating a mindful approach to eating and managing stress can enhance the benefits of the AIP diet and promote better overall health.

4. Seek Professional Guidance

Working with a qualified healthcare professional or registered dietitian who specializes in autoimmune conditions can provide invaluable guidance and support. They can help tailor the AIP diet to your specific needs, monitor your progress, and address any concerns or questions you may have along the way.

5. Long-Term Maintenance

The AIP diet is often followed as an elimination and reintroduction protocol to identify trigger foods. However, some individuals may choose to maintain a modified version of the AIP diet in the long term to manage their autoimmune conditions. This may involve incorporating personalized food choices and reintroducing tolerated foods while still prioritizing nutrient density and minimizing inflammatory triggers.


Q1. How long should I follow the elimination phase of the AIP diet?

The duration of the elimination phase varies for each individual. It is generally recommended to follow the elimination phase for a period of 30 to 90 days. This timeline allows the body time to heal and reset. After this initial phase, foods can be reintroduced gradually to identify any trigger foods.

Q2. Can I follow the AIP diet if I have dietary restrictions?

Yes, the Aip diet can be adapted to accommodate various dietary restrictions. It can be modified to be gluten-free, dairy-free, and even accommodate specific food allergies or sensitivities.

Q3. Is it challenging to follow the AIP diet?

Although the AIP diet may seem challenging at first, with proper planning and preparation, it can be navigated successfully. There are numerous online resources, recipes, and community support groups available, making it easier to comply with the diet.

Q4. Can I still enjoy eating out while on the AIP diet?

Eating out can pose challenges, as many restaurant dishes contain ingredients that are not AIP-compliant. However, with careful communication and customization, many restaurants are willing to accommodate dietary needs. It’s essential to inquire about menu options, ask for ingredient substitutions, and communicate your dietary restrictions to ensure a suitable meal.

The Bottom Line

The AIP diet, also known as the autoimmune protocol diet, offers a unique and targeted approach to managing autoimmune conditions. By eliminating inflammatory trigger foods and focusing on nutrient-dense options, the AIP diet aims to reduce inflammation, alleviate symptoms, and support overall health.
