Skin conditions like eczema and psoriasis are more than just surface problems. They are signs that something deeper is happening inside your body. Inflammation is the root cause. And diet plays a massive role in controlling it.
The AIP Diet, or Autoimmune Protocol Diet, is designed exactly for this. It removes foods that trigger immune flares and replaces them with nutrient-dense, healing foods. For people dealing with eczema and psoriasis, the AIP Diet can be a real turning point.
At Paleo Tiger, we have spent years studying how food affects autoimmune skin conditions. We have built a full line of AIP-friendly tiger nut products that make it easy, satisfying, and delicious to follow this lifestyle. In this guide, you will learn exactly what to eat, what to avoid, and how our products can support your skin healing journey.
Let’s get started.
What Is the AIP Diet and Why Does It Matter for Skin?
The AIP Diet is an elimination protocol. It was developed to reduce inflammation and support gut healing. Because the gut and the immune system are deeply connected, healing the gut often leads to better skin health.
Studies show that up to 70% of the immune system lives in the gut. When the gut lining is damaged, a condition called “leaky gut”, undigested food particles enter the bloodstream and trigger immune responses. Those responses often show up on the skin as eczema or psoriasis flares.
The AIP Diet removes foods that damage the gut lining and floods the body with nutrients that heal it. This makes it one of the most powerful dietary approaches for managing eczema and psoriasis naturally.
Here is a quick overview:
| Feature | AIP Diet |
| Goal | Reduce inflammation, heal gut lining |
| Duration | Elimination phase: 30–90 days |
| Reintroduction | Gradual, food by food |
| Focus foods | Vegetables, quality meats, fermented foods, tiger nuts |
| Eliminated foods | Grains, dairy, eggs, legumes, nightshades, nuts, seeds |
| Skin benefit | Reduces eczema and psoriasis flares |
The Connection Between Gut Health and Skin Conditions
Before diving into the food lists, you need to understand this connection. Your skin is not separate from your digestive system. They are linked through what scientists call the gut-skin axis.
When your gut microbiome is balanced and diverse, your immune system stays calm. But when harmful bacteria overgrow, or when the gut lining breaks down, inflammation spreads, including to the skin.
Research published in clinical journals confirms that patients with psoriasis have significantly altered gut bacteria compared to healthy individuals. The same is true for eczema sufferers. This is exactly why dietary changes can produce visible skin improvements.
Prebiotic fiber is one of the most important tools for rebuilding a healthy gut. And this is where tiger nuts shine. Tiger nuts are one of the richest sources of prebiotic fiber available, feeding the good bacteria that protect your gut and, in turn, your skin.
This is not a coincidence. Paleo Tiger built its entire product line around tiger nuts’ extraordinary gut-healing potential.
AIP Diet for Eczema and Psoriasis, Foods to Eat
The AIP Diet is not about restriction alone. It is about replacing inflammatory foods with deeply nourishing ones. Here is your complete guide to what to eat.
1. Non-Starchy and Starchy Vegetables
Vegetables are the foundation of the AIP Diet. They are rich in antioxidants, minerals, and fiber. Aim to fill at least 50% of your plate with vegetables at every meal.
Best vegetables for eczema and psoriasis on AIP:
- Leafy greens (spinach, kale, Swiss chard, arugula)
- Beets and carrots
- Zucchini and squash
- Broccoli and cauliflower
- Sweet potatoes and yams
- Plantains and cassava
- Kabocha squash
- Turnips and rutabaga
Starchy vegetables like sweet potatoes and plantains are especially important. They provide energy, support the microbiome, and keep blood sugar stable, all of which help manage eczema and psoriasis flares.
2. Quality Proteins
Protein helps repair skin cells and support immune function. On the AIP Diet, you focus on high-quality animal proteins and avoid processed meats.
Best protein sources for AIP:
- Grass-fed beef and lamb
- Wild-caught fish and seafood (salmon, sardines, mackerel)
- Pasture-raised poultry
- Organ meats (liver, heart, extremely nutrient-dense)
- Bone broth (great for gut lining repair)
Omega-3 fatty acids found in fatty fish are especially helpful for psoriasis and eczema. They reduce inflammatory signals in the body.
3. Healing Fats
Healthy fats are essential on the AIP Diet. They support skin hydration, reduce inflammation, and carry fat-soluble vitamins.
Best fats for AIP:
- Avocado and avocado oil
- Coconut oil and coconut milk
- Olive oil
- Tiger nut oil (cold-pressed)
- Lard and tallow from pastured animals
Paleo Tiger’s 100% cold-pressed tiger nut oil is exceptional here. It is rich in oleic acid, the same heart-healthy monounsaturated fat found in olive oil, plus vitamin E, which is known for its skin-protective properties. Many people using the AIP Diet for eczema find that adding tiger nut oil to their routine makes a noticeable difference.
4. Fermented Foods
Fermented foods introduce beneficial bacteria directly into the gut. They are one of the most powerful tools for rebuilding gut health on the AIP Diet.
Best AIP-compliant fermented foods:
- Coconut milk kefir
- Coconut milk yogurt
- Kimchi (nightshade-free)
- Sauerkraut
- Kombucha (low-sugar)
- Water kefir
5. Tiger Nuts: The Star AIP Food for Skin Health
We cannot talk about the AIP Diet for eczema and psoriasis without highlighting tiger nuts. These small, earthy tubers (not actual nuts) are one of the most nutrient-dense AIP-compliant foods on the planet.
Why tiger nuts are exceptional for eczema and psoriasis:
| Nutrient | Benefit for Skin |
| Prebiotic fiber (resistant starch) | Feeds good gut bacteria, reduces gut inflammation |
| Vitamin E | Antioxidant protection for skin cells |
| Oleic acid (monounsaturated fat) | Supports skin hydration and barrier function |
| Magnesium | Reduces inflammatory stress responses |
| Zinc | Critical for skin repair and immune regulation |
| Iron | Supports oxygen delivery to skin cells |
| Potassium | Regulates cellular hydration |
Tiger nuts are naturally free from grains, dairy, eggs, legumes, and nightshades. They are completely AIP-compliant and perfect for anyone managing eczema or psoriasis through diet.

AIP Diet for Eczema and Psoriasis: Foods to Avoid
Knowing what to avoid is just as important as knowing what to eat. The following foods are eliminated during the AIP Diet because they are the most common triggers for autoimmune flares, including eczema and psoriasis.
Complete AIP Elimination List
| Food Category | Examples | Why Eliminated |
| Grains | Wheat, rice, oats, corn, quinoa | Damage gut lining, trigger inflammation |
| Legumes | Beans, lentils, peanuts, soy | Anti-nutrients, gut irritants |
| Dairy | Milk, cheese, butter, whey | Casein and lactose drive immune reactions |
| Eggs | All eggs (especially whites) | Common autoimmune trigger |
| Nightshades | Tomatoes, peppers, potatoes, eggplant | Alkaloids increase gut permeability |
| Nuts & seeds | Almonds, cashews, chia, flax | Pro-inflammatory omega-6 excess, gut irritants |
| Refined sugars | White sugar, HFCS, artificial sweeteners | Feed harmful bacteria, spike inflammation |
| Processed oils | Canola, soybean, corn oil | Oxidized fats that damage cells |
| Alcohol | All forms | Directly damages gut lining |
| Coffee | All coffee | Gut irritant, disrupts cortisol |
| NSAIDs | Ibuprofen, aspirin | Damage gut mucosa |
This is a comprehensive list. But do not be discouraged. The AIP Diet is about abundance, not deprivation. And with Paleo Tiger’s full range of products, you never feel like you are missing out.
Pros and Cons of the AIP Diet for Skin Conditions
It is important to be honest. The AIP Diet is not easy, especially at first. Here is a balanced look:
| Pros | Cons |
| Directly targets root causes of eczema and psoriasis | Restrictive, especially in social settings |
| Heals gut lining and rebuilds microbiome | Requires significant meal planning |
| Reduces dependence on medications | Takes time, results in 4–12 weeks typically |
| Provides a personalised understanding of triggers | Reintroduction phase can be confusing |
| Nutrient-dense whole foods support overall health | Higher food costs in some cases |
| Supports mental clarity and energy levels | Needs professional support ideally |
The good news: Paleo Tiger makes the food side dramatically easier. Our ready-to-eat tiger nut butters, granola, and snack products remove the guesswork from meal planning on the AIP Diet.
What Does the Science Say?
The research on dietary intervention for eczema and psoriasis is growing. Here are key statistics and findings:
- Studies show that patients with psoriasis who follow elimination diets report up to 50–60% improvement in symptom severity scores after 12 weeks.
- Research published in Frontiers in Immunology confirms that gut microbiome diversity is significantly reduced in eczema patients compared to healthy controls.
- Resistant starch, the primary fiber in tiger nuts, has been shown to increase populations of Bifidobacterium and Lactobacillus, two key bacteria linked to reduced skin inflammation.
- A 2022 review found that omega-3 supplementation reduced psoriasis severity scores by an average of 40% in randomized controlled trials.
- The AIP Diet clinical trial published in Inflammatory Bowel Disease found that 73% of participants achieved clinical remission after 6 weeks.
These numbers are not marketing. They are backed by real science. And the AIP Diet built around foods like tiger nuts is one of the most evidence-based nutritional approaches for calming skin conditions rooted in immune dysfunction.
Step-by-Step, Starting the AIP Diet for Eczema and Psoriasis
Starting can feel overwhelming. But broken into clear steps, it becomes manageable.
Phase 1: Elimination (30–90 Days)
Remove all foods on the elimination list. Focus on:
- Meat and fish at every meal
- Abundant vegetables (including starchy ones)
- Tiger nut butter and whole tiger nuts as snacks
- Tiger nut flour for baking
- Tiger nut oil for cooking and skin support
- Fermented foods daily
- Bone broth (2–3 cups daily)
This is where healing happens. Do not rush this phase.
Phase 2: Reintroduction (Week by Week)
After at least 30 days of strict elimination (and when symptoms have significantly improved), you begin reintroducing foods one at a time.
Reintroduction order (safest first):
- Egg yolks
- Legume pods (green beans, snap peas)
- Seed-based spices (cumin, coriander)
- Nuts and seeds soaked/sprouted
- Egg whites
- Nightshade vegetables (cooked)
- Dairy (fermented first, kefir, ghee)
- Grains (gluten-free first)
Rule: Eat the new food 2–3 times over 2 days. Then wait 5 days. Watch for any return of eczema or psoriasis symptoms.
Phase 3: Personalisation
After completing reintroduction, you know your personal triggers. You build a long-term eating pattern that keeps your skin clear. Tiger nut products stay in your diet throughout all phases; they are always AIP-compliant and always beneficial.

Lifestyle Factors That Support AIP for Skin
Diet is the core pillar. But these lifestyle habits amplify your results:
Sleep
Poor sleep spikes cortisol. Cortisol drives inflammation. Aim for 7–9 hours of quality sleep every night.
Stress Management
Chronic stress is a direct trigger for eczema and psoriasis flares. Try daily walks, meditation, journaling, or breathwork.
Gentle Exercise
Moderate exercise reduces inflammation markers. Avoid excessive high-intensity training in early stages, as it can increase cortisol temporarily.
Sun Exposure
Sunlight triggers vitamin D production, which plays a key role in regulating the immune system. Aim for 15–20 minutes of direct sunlight daily when possible.
Topical Support
Paleo Tiger’s cold-pressed tiger nut oil can be applied directly to affected skin. Its vitamin E content and oleic acid profile make it deeply moisturising and anti-inflammatory. Many people using the AIP Diet for eczema report faster skin healing when combining dietary tiger nut products with topical tiger nut oil.

AIP Diet for Eczema vs. Psoriasis
While the core AIP Diet protocol applies to both conditions, there are subtle differences worth knowing:
| Factor | Eczema (Atopic Dermatitis) | Psoriasis |
| Immune pathway | Th2-dominant response | Th17/Th1-dominant response |
| Main trigger | Allergens, gut permeability | Gut dysbiosis, stress, immune dysfunction |
| Key nutrients | Zinc, vitamin E, omega-3 | Vitamin D, omega-3, magnesium |
| Dietary priority | Elimination of allergens | Elimination of gut irritants |
| AIP phase 1 duration | 30–60 days | 60–90 days typically |
| Tiger nut benefit | Prebiotic fiber, zinc, vitamin E | Resistant starch, magnesium, anti-inflammatory fats |
Both conditions respond powerfully to the AIP Diet. And tiger nuts are uniquely positioned to support both through their broad nutrient profile.
Common Mistakes on the AIP Diet for Skin Conditions
Avoid these pitfalls for best results:
- Not eating enough calories. AIP can feel restrictive. Eat plenty of starchy vegetables and healthy fats like tiger nut butter to maintain energy.
- Skipping fermented foods. These are essential for microbiome rebuilding. Include them daily.
- Reintroducing too early. Wait until symptoms have clearly improved before starting Phase 2.
- Not tracking reactions. Keep a food and skin diary during reintroduction. It reveals your personal triggers.
- Choosing poor-quality snacks. Many “AIP” products on the market contain hidden inflammatory ingredients. Stick with trusted brands like Paleo Tiger.
- Going it alone. Work with a functional medicine practitioner when possible. The AIP Diet is powerful, and professional support accelerates results.
