Bone broth has gained popularity in recent years as a nutritious and healing food. It is a staple in the Autoimmune protocol (AIP) diet, which is designed to reduce inflammation and support the immune system. The AIP diet eliminates foods that are known to trigger autoimmune reactions, such as grains, dairy, legumes, and processed foods. Instead, it focuses on nutrient-dense foods that promote gut health and reduce inflammation. Bone broth is one such food that plays a crucial role in the AIP diet. In this article, we will explore the benefits of bone broth and its role in supporting the AIP diet.

The Nutritional Profile of Bone Broth

Bone broth is made by simmering animal bones and connective tissues for an extended period, typically 24-48 hours. This slow cooking process extracts valuable nutrients from the bones, resulting in a nutrient-dense broth. Here are some key nutrients found in bone broth:

  • Collagen: Bone broth is rich in collagen, a protein that provides structure to the skin, bones, and connective tissues. Consuming collagen-rich foods like bone broth can support joint health and improve skin elasticity.
  • Gelatin: When collagen is cooked, it breaks down into gelatin. Gelatin is known for its gut-healing properties and can help repair the lining of the digestive tract.
  • Minerals: Bone broth is a good source of minerals like calcium, magnesium, and phosphorus, which are essential for bone health.
  • Amino Acids: Bone broth contains various amino acids, including glycine, proline, and glutamine. These amino acids play a crucial role in supporting gut health, reducing inflammation, and promoting detoxification.
  • Hydration: Bone broth is a hydrating beverage that can help replenish electrolytes and maintain fluid balance in the body.

The nutritional profile of bone broth makes it an excellent addition to the AIP diet, as it provides essential nutrients that support overall health and healing.

Supporting Gut Health

Gut health is a key focus of the AIP diet, as many autoimmune diseases are believed to be rooted in gut dysfunction. The gut lining can become compromised due to factors like poor diet, stress, and certain medications. This compromised gut lining, also known as “leaky gut,” allows undigested food particles and toxins to enter the bloodstream, triggering an immune response and inflammation.

Bone broth contains gelatin, which can help repair the gut lining and reduce intestinal permeability. The amino acids in bone broth, such as glycine and glutamine, also support gut health by nourishing the cells of the intestinal lining and promoting the growth of beneficial gut bacteria.

Furthermore, bone broth is rich in collagen, which has been shown to support the growth and repair of the intestinal lining. A study published in the journal Cellular and Molecular Gastroenterology and Hepatology found that collagen supplementation improved gut barrier function and reduced inflammation in mice with colitis, a type of inflammatory bowel disease.

Reducing Inflammation

Inflammation is a common feature of autoimmune diseases, and reducing inflammation is a primary goal of the AIP diet. Bone broth can help in this regard due to its anti-inflammatory properties.

One of the key anti-inflammatory compounds found in bone broth is glycine. Glycine has been shown to inhibit the production of pro-inflammatory cytokines, which are molecules that promote inflammation in the body. A study published in the journal Mediators of Inflammation found that glycine supplementation reduced inflammation and oxidative stress in rats with colitis.

Additionally, the amino acid proline found in bone broth has been shown to have anti-inflammatory effects. Proline can inhibit the production of pro-inflammatory molecules and promote the production of anti-inflammatory molecules.

Supporting Joint Health

Many autoimmune diseases, such as rheumatoid arthritis and lupus, can cause joint pain and inflammation. Bone broth can be particularly beneficial for individuals with these conditions due to its ability to support joint health.

The collagen and gelatin found in bone broth provide the building blocks for healthy joints. Collagen helps maintain the integrity of cartilage, which is the connective tissue that cushions the joints. Consuming collagen-rich foods like bone broth can support joint health and reduce joint pain.

A study published in the journal Current Medical Research and Opinion found that collagen supplementation improved symptoms of osteoarthritis, a degenerative joint disease. Participants who consumed collagen experienced a significant reduction in joint pain and an improvement in physical function.

Boosting the Immune System

The AIP diet aims to support the immune system, which is often dysregulated in autoimmune diseases. Bone broth can play a role in boosting the immune system due to its rich nutrient profile.

The amino acid glutamine found in bone broth is known for its immune-boosting properties. Glutamine is a fuel source for immune cells and can enhance their function. A study published in the journal Frontiers in Immunology found that glutamine supplementation improved immune cell function and reduced inflammation in mice.

Furthermore, the minerals and vitamins present in bone broth, such as zinc and vitamin C, are essential for immune function. Zinc is involved in various immune processes, including the development and function of immune cells. Vitamin C is a potent antioxidant that supports immune cell function and helps protect against oxidative stress.


Bone broth is a valuable addition to the AIP diet due to its numerous health benefits. It supports gut health, reduces inflammation, promotes joint health, and boosts the immune system. The collagen, gelatin, and amino acids found in bone broth provide essential nutrients that support overall health and healing. Incorporating bone broth into the AIP diet can be a simple and effective way to nourish the body and support the management of autoimmune diseases.
