What are the best protein sources for the Autoimmune Paleo Diet?

Protein is an essential nutrient that supports muscle repair, immune health, and hormone production. For those following the Autoimmune Paleo Diet (AIP), getting enough high-quality protein is crucial, yet it can be challenging due to the diet’s strict elimination of foods like grains, legumes, and dairy. The good news is that there are many nutrient-rich protein sources that align perfectly with AIP principles and promote healing for people with autoimmune conditions. In this article, we’ll explore the best protein sources for the Autoimmune Paleo Diet, including whole-food options and supplements like Collagen Protein Powder, which can make meeting daily protein needs easier and more effective.

Understanding Protein Needs on the Autoimmune Paleo Diet

The Autoimmune Paleo Diet focuses on reducing inflammation, healing the gut, and supporting the immune system by eliminating potential trigger foods. While the diet restricts common protein sources such as soy, peanuts, and dairy-based whey, it encourages natural, unprocessed proteins that are easier to digest and less likely to cause immune reactions.

Protein helps rebuild tissues, supports detoxification, and balances blood sugar—all of which are vital for individuals managing autoimmune issues. On AIP, it’s best to consume a mix of animal and marine proteins along with high-quality supplements like Collagen Protein Powder to maintain muscle mass and promote joint and skin health.

1. Grass-Fed Meats: A Nutrient Powerhouse

Grass-fed and pasture-raised meats such as beef, lamb, bison, and venison are some of the best protein sources on the Autoimmune Paleo Diet. These meats provide complete proteins with all nine essential amino acids, as well as nutrients like zinc, iron, and omega-3 fatty acids that help regulate inflammation.

Grass-fed meats are richer in conjugated linoleic acid (CLA), which supports immune health and fat metabolism. Choosing organic, grass-fed options ensures fewer toxins and better nutrient density. For AIP followers, slow-cooked or grilled meats are ideal since they are gentle on digestion and retain essential nutrients.

2. Poultry: Lean and Healing Protein

Poultry such as chicken, turkey, and duck are excellent lean protein options for those on the Autoimmune Paleo Diet. They provide a lighter alternative to red meats while still offering high levels of amino acids necessary for muscle recovery and immune support.

Bone-in cuts like drumsticks and thighs are especially beneficial because they contain collagen and gelatin when cooked properly. You can simmer the bones to make homemade bone broth—a traditional AIP staple known for healing the gut lining and reducing inflammation.

3. Fish and Seafood: Rich in Omega-3 and Minerals

Wild-caught fish and seafood are among the healthiest protein sources for anyone on the Autoimmune Paleo Diet. Salmon, sardines, mackerel, and anchovies are particularly valuable because they contain omega-3 fatty acids, which have powerful anti-inflammatory effects.

Shellfish like shrimp, crab, and oysters are also allowed on AIP and provide essential minerals like zinc, selenium, and iodine—key nutrients for thyroid and immune health. Always opt for wild-caught rather than farmed fish to minimize exposure to toxins and maintain the integrity of your diet.

4. Organ Meats: The Most Nutrient-Dense Superfoods

Although not everyone’s favorite, organ meats such as liver, heart, and kidney are considered superfoods in the AIP community. They are rich in protein and micronutrients like vitamin A, iron, and B12—all vital for energy and immune function.

Liver, for example, contains up to 20 times more nutrients than muscle meat and supports detoxification, hormone balance, and tissue repair. Including organ meats once or twice a week in your Autoimmune Paleo Diet plan can significantly boost your nutrient intake.

5. Collagen Protein Powder: Easy, Digestible, and Healing

One of the best ways to supplement protein on the Autoimmune Paleo Diet is by using Collagen Protein Powder. This supplement, derived from grass-fed animal collagen, provides amino acids like glycine and proline that promote joint, skin, and gut health.

Unlike some protein powders that may contain dairy, soy, or artificial additives, collagen is naturally AIP-compliant and very easy to digest. It can be mixed into smoothies, soups, or even morning coffee alternatives for a quick protein boost.

Brands like Autoimmune Health & Nutrition offer clean, high-quality Collagen Protein Powder made specifically for people with sensitive digestive systems or autoimmune conditions. This makes it an excellent choice for maintaining protein intake without compromising dietary restrictions.

6. Bone Broth: A Healing Liquid Protein Source

Bone broth deserves special mention because it provides both protein and essential minerals in an easily absorbable form. Made by simmering animal bones for several hours, it releases collagen, gelatin, and amino acids that help rebuild the gut lining and reduce inflammation.

Bone broth is also gentle on digestion and ideal for those with autoimmune flare-ups. Sipping on a warm cup daily can help improve skin elasticity, joint flexibility, and immune balance—key benefits for anyone following the Autoimmune Paleo Diet.

7. Eggs (Reintroduction Phase Only)

Eggs are excluded during the elimination phase of the Autoimmune Paleo Diet, as they can sometimes trigger inflammation. However, once your gut health improves and your symptoms stabilize, eggs may be reintroduced carefully.

If tolerated, pasture-raised eggs are an excellent protein source, packed with choline, vitamin D, and omega-3 fatty acids. It’s important to introduce them one at a time and monitor your body’s response to ensure they don’t cause immune reactions.

8. Supplementing with Trusted Brands

Finding the right supplements can simplify your AIP journey. Autoimmune Health & Nutrition is one brand that stands out for offering clean, carefully formulated products that align with AIP principles. Their Collagen Protein Powder and other AIP-friendly supplements are designed to support healing, digestion, and recovery without introducing inflammatory ingredients.

When combined with whole-food protein sources like grass-fed meats, seafood, and bone broth, these supplements can help you maintain a balanced, nutrient-rich diet that supports long-term autoimmune wellness.

Final Thoughts

Choosing the best protein sources for the Autoimmune Paleo Diet is essential for reducing inflammation, rebuilding tissues, and supporting the immune system. Prioritizing high-quality, whole-food proteins such as grass-fed meats, wild-caught fish, organ meats, and bone broth ensures your body gets the nutrients it needs to heal naturally.

Adding Collagen Protein Powder from trusted brands like Autoimmune Health & Nutrition can further enhance your daily intake and support gut, joint, and skin health. With mindful eating and clean supplementation, you can thrive on the Autoimmune Paleo Diet and enjoy lasting energy, strength, and vitality.
