The AIP diet, short for Autoimmune Protocol Diet, is a targeted nutritional strategy designed to reduce inflammation, soothe the gut, and manage symptoms associated with autoimmune diseases. If you’ve ever asked yourself, “What is an AIP diet and how can it help me?”, you’re in the right place.
This dietary approach eliminates foods that are known to irritate the immune system and gut lining and reintroduces them strategically to identify triggers. Rooted in principles of the Paleo diet, the AIP diet takes it a step further by eliminating even more potential inflammatory foods for a certain period.
In this article, we’ll break down what the AIP diet is, how it works, its benefits, what to eat and avoid, and how to get started on your healing journey.
Understanding the Basics of the AIP Diet
Autoimmune diseases occur when the body’s immune system mistakenly attacks its own tissues. Conditions like rheumatoid arthritis, Hashimoto’s thyroiditis, lupus, and psoriasis are all examples.
The AIP diet aims to:
- Calm the immune system
- Heal the gut lining
- Reduce systemic inflammation
- Identify food sensitivities or intolerances
The AIP diet typically follows two phases:
- Elimination Phase: You remove inflammatory foods, including grains, dairy, legumes, nightshades, nuts, seeds, eggs, and processed foods.
- Reintroduction Phase: After symptoms have improved, you slowly reintroduce foods to determine which ones trigger a reaction.
How Is the AIP Diet Different From Paleo?
While both diets avoid grains, legumes, and processed foods, the AIP diet is more restrictive. It eliminates additional food groups that are allowed in Paleo, such as:
- Eggs
- Nuts and seeds
- Nightshade vegetables (tomatoes, peppers, eggplants, potatoes)
- Coffee and alcohol
- Emulsifiers and food additives
This extra level of restriction helps people with autoimmune conditions uncover more subtle dietary triggers.
Health Benefits of the AIP Diet
Although the AIP diet can feel restrictive at first, it offers several benefits, particularly for people with autoimmune disorders:
- Reduced inflammation
- Improved digestion and gut health
- Better energy levels
- Less joint pain and stiffness
- Clearer skin
- Fewer autoimmune flare-ups
- Enhanced mental clarity
Some studies and anecdotal evidence also suggest the AIP diet may help regulate hormones and improve mood.
What to Eat on the AIP Diet
Here’s a list of AIP-friendly foods you can enjoy during the elimination phase:
- Meat and fish: Grass-fed, pasture-raised, and wild-caught are ideal.
- Vegetables: All except nightshades.
- Fruits: In moderation.
- Healthy fats: Olive oil, coconut oil, avocado oil.
- Herbs: Basil, parsley, oregano, rosemary, etc.
- Bone broth: Excellent for gut healing.
- Fermented foods: Sauerkraut, kombucha (without added sugars), coconut yogurt.
Foods to Avoid on the AIP Diet
To calm the immune system, it’s essential to remove these common inflammatory and also gut-irritating foods:
- Grains (wheat, rice, oats, corn)
- Dairy (milk, cheese, yogurt)
- Legumes (beans, peanuts, soy)
- Nuts and seeds (including coffee and chocolate)
- Nightshades (tomatoes, potatoes, peppers, eggplant)
- Eggs
- Processed sugars
- Industrial seed oils (canola, soybean)
- Alcohol and caffeine
- Food additives and preservatives
How Long Should You Follow the AIP Diet?
The elimination phase typically lasts between 30 and 90 days. After that, you begin the reintroduction phase, which is gradual and intentional.
Each food is reintroduced one at a time, spaced several days apart, while monitoring symptoms such as bloating, fatigue, joint pain, skin issues, or headaches. If a food causes symptoms, it should be avoided longer before trying again.
Tips for Getting Started with the AIP Diet
- Plan your meals in advance.
- Clean out your pantry to remove non-compliant foods.
- Batch cook for convenience.
- Track your symptoms and food intake in a journal.
- Work with a practitioner, especially if you have multiple autoimmune issues or nutritional concerns.
Is the AIP Diet Right for You?
If you have an autoimmune condition or struggle with chronic inflammation and fatigue, trying the AIP diet could be a powerful way to reduce symptoms and feel better. However, because it’s restrictive, it’s best to approach it mindfully and ensure you’re getting balanced nutrition. See our other blogs.
