Endometriosis is a chronic inflammatory condition where tissue similar to the lining of the uterus grows outside of it, affecting approximately 1 in 10 women during their reproductive years in the United States. This can lead to a range of symptoms, including painful periods, heavy bleeding, digestive issues, and fatigue. While there is currently no known cure for endometriosis, various management strategies exist, including excision surgery, pain management plans, lifestyle adjustments, and dietary modifications. One dietary approach that has gained attention is the Autoimmune Protocol (AIP) diet.
Understanding Endometriosis
Endometriosis is characterized by the presence of endometrial-like tissue outside the uterus, most commonly in the pelvic area, but it can also occur in other parts of the body. The symptoms of endometriosis often worsen around menstruation and can include:
- Pelvic pain
- Increased pain during periods and intercourse
- Pain with bowel movements and urination
- Heavy periods or bleeding between periods
- Fatigue
- Diarrhea
- Bloating
- Constipation
- Low back pain
- Intense cramping
Untreated endometriosis can lead to infertility and may slightly increase the risk of ovarian cancer. Comprehensive care, including pain management, a healthy lifestyle, good nutrition, and exercise, is essential for managing the condition.
The Autoimmune Protocol (AIP) Diet: An Overview
The Autoimmune Protocol (AIP) diet is an elimination diet designed to reduce inflammation, support gut health, and manage autoimmune conditions. The AIP diet is centered around foods that assist in keeping inflammation low. Chronic inflammation, caused by things like processed foods, sugar, and some grains, can upset hormone balance and make conception more difficult. Reducing inflammation accomplishes more than soothing the immune system; it helps with menstrual cycles and can even make ovulation more predictable.
It involves two main phases:

- Elimination Phase: This phase involves removing foods that are believed to trigger inflammation and immune responses.
- Reintroduction Phase: After a period of elimination, foods are gradually reintroduced to identify individual triggers and create a personalized, sustainable diet.
The AIP Diet and Endometriosis: Potential Benefits
While endometriosis is not an autoimmune condition, it shares features with autoimmune diseases, including systemic inflammation. The AIP diet's focus on reducing inflammation and supporting gut health may offer potential benefits for individuals with endometriosis.
1. Reducing Inflammation:
The AIP diet eliminates foods that are known to promote inflammation, such as:
- Grains
- Dairy
- Legumes
- Nuts and seeds
- Nightshade vegetables (tomatoes, peppers, eggplants, potatoes)
- Processed foods
- Refined sugars
- Eggs
By removing these potential triggers, the AIP diet aims to lower overall inflammation in the body, which may help alleviate endometriosis symptoms.
2. Supporting Gut Health:
The AIP diet emphasizes foods that promote gut health, such as:
- Bone broth
- Fermented foods (e.g., sauerkraut, kimchi)
- Non-starchy vegetables
A healthy gut microbiome is essential for hormone metabolism and immune function. Stronger gut health, in turn, makes the body better able to absorb the vitamins and minerals crucial for egg and sperm quality. If the gut is inflamed, nutrient absorption plummets, and this can damage fertility.

3. Managing FODMAPs:
The AIP diet naturally reduces high-FODMAP foods (Fermentable Oligo-, Di-, Mono-saccharides, and Polyols), which are short-chain carbohydrates that can cause digestive discomfort in some individuals. By removing these foods, the AIP diet can improve gut health and reduce digestive discomfort.
4. Hormone Regulation:
Hormones are in charge of fertility. The AIP diet supports the body to produce and regulate hormones including estrogen, progesterone, and insulin. This transition may result in improved ovulation and more consistent cycles.
5. Nutrient Density:
The AIP diet encourages the consumption of nutrient-dense foods, such as:
- Meat and Fish: Grass-fed, pasture-raised, and wild-caught options are preferred.
- Vegetables and fruits
These foods provide essential vitamins, minerals, and antioxidants that can support overall health and well-being. These key nutrients-iron, folate, vitamin D, and omega-3s-are easy to obtain on AIP. These nutrients help maintain egg and sperm health and early pregnancy. Nutrient gaps can complicate fertility. The AIP diet’s emphasis on diversity-berries, greens, organ meats, and seafood, addresses these gaps.
Foods to Include in an AIP Diet for Endometriosis
To fight inflammation and pain caused by endometriosis, it’s best to consume a nutrient-dense, well-balanced diet that’s primarily plant-based and full of vitamins and minerals.

- Fibrous foods, such as fruits, vegetables, legumes, and whole grains
- Iron-rich foods, such as dark leafy greens, broccoli, beans, fortified grains, nuts, and seeds
- Foods rich in essential fatty acids, such as salmon, sardines, herring, trout, walnuts, chia, and flax seeds
- Antioxidant-rich foods found in colorful fruits and vegetables, such as oranges, berries, dark chocolate, spinach, and beets
Considerations and Potential Drawbacks
While the AIP diet may offer benefits for some individuals with endometriosis, it is essential to consider the following:
1. Restrictiveness and Sustainability:
The AIP diet is highly restrictive, which can make long-term adherence challenging. It may also lead to social isolation and difficulty eating out. Consuming excessive red and processed meat, sugar, and foods rich in refined carbs and bad fats can trigger more inflammation leading to lower fertility. These could reduce sperm quality in men and potentially increase the risk of endometriosis in women. Junk drinks and a diet low on fruits and veggies can increase body fat and disrupt hormone equilibrium, which can additionally decrease fertility likelihood.
2. Risk of Nutrient Deficiencies:
The elimination of several food groups can increase the risk of nutrient deficiencies, such as calcium, vitamin D, and B vitamins. It is crucial to work with a healthcare professional to ensure adequate nutrient intake through supplementation or careful food selection. Without sufficient amounts of these, it can be difficult to maintain healthy bones, hormones and energy-key components for fertility. Monitoring health is important when implementing major diet shifts. If you begin feeling lethargic or weak, or notice changes in your skin or hair, it can indicate a nutrient deficiency. Periodic blood tests and candid conversations with your doctor or dietitian are wise moves.
3. Eating Disorders:
Restrictive diets can increase the risk of developing eating disorders or disordered eating patterns. It is essential to approach the AIP diet with caution, especially if there is a history of eating disorders. Diets don’t work long-term and are associated with poor health outcomes in the long term, weight gain, and bingeing.
4. Lack of Scientific Evidence:
There is currently limited scientific research on the AIP diet's effectiveness for endometriosis. While some individuals report symptom relief, more studies are needed to determine its efficacy and long-term effects. Unfortunately, there have been no scientific studies on it to date.
5. Personalization:
The AIP framework should be tailored to individual needs and preferences. Not everyone responds individually to foods. Others could have to reintroduce eggs, nuts, or dairy to prevent nutrient gaps. It helps to remain open to adaptation, monitor how the body feels and responds, and adjust the diet accordingly.
A Balanced Approach: Combining AIP with Other Strategies
The AIP diet can be a valuable tool for managing endometriosis symptoms, but it should not be considered a standalone treatment. A comprehensive approach that includes medical care, lifestyle modifications, and emotional support is essential.
1. Medical Management:
Consult with a healthcare provider for diagnosis, treatment options, and pain management strategies. Excision surgery is often considered the gold standard of care for endometriosis.
2. Lifestyle Modifications:
In addition to diet, other lifestyle factors can influence endometriosis symptoms. These include:
- Regular exercise: Exercise may help with the management of endometriosis, too. This is because exercise can reduce estrogen levels and release “feel-good” hormones.
- Stress management: Chronic stress may disrupt hormone balance and reduce fertility. It increases inflammation, which is already an issue for people on an autoimmune protocol. Mindfulness, breathing exercises, or gentle movement like yoga can reduce stress.
- Adequate sleep: Quality sleep helps keep hormones in check - and that’s key for fertility. When sleep is limited in duration or interrupted, the body doesn’t produce or secrete hormones necessary for egg or sperm viability.
- Avoiding trans fats: Research has found higher rates of endometriosis diagnoses among women who consume more trans fat. Trans fat is found predominately in fried, processed, and fast foods.
3. Supplements:
In addition to eating a healthy diet, supplements may be beneficial as well.
- Vitamin E and C: Results showed a reduction in chronic pelvic pain and a decrease in inflammation.
- Zinc and vitamins A, C, and E: Women with endometriosis who took these supplements decreased peripheral oxidative stress markers and enhanced antioxidant markers.
- Vitamin D, calcium and magnesium: Women with a higher vitamin D level and those who had a higher intake of dairy in their diet had a decreased rate of endometriosis.
4. Alternative Therapies:
In addition to conventional methods of treatment, alternative treatments may be very helpful for women with endometriosis. For example, relaxation techniques may be beneficial. These can include: meditation, yoga, acupuncture, massage.
The Role of Diet in Endometriosis: Further Research
Dietary factors can be related to endometriosis etiology due to their role in regulating steroid hormone metabolism, the effect on muscle contraction, regulating inflammation, oxidative stress, and the menstrual cycle. Some observational studies showed that a plant-based diet leads to a decrease in the bioavailability of estrogen, estrogen plays a role in inducing extra-uterine endometrial tissue proliferation. Higher consumption of fruits and green vegetables may be protective because it can decrease inflammatory markers such as interleukin-6 (IL-6) that are elevated among women diagnosed with endometriosis. Dairy products contain anti-inflammatory and anti-oxidative agents, vitamin D, and calcium that may induce a protective effect in endometriosis. Fish oil consumption may lead to a decreased risk of endometriosis due to its anti-inflammatory effects, while high trans-fat intake leads to an increased risk of endometriosis. Red meat is another dietary factor that may be related to an increased risk of endometriosis because it can affect estrogen levels that are involved in the pathogenesis of endometriosis by promoting the expression and release of pro-inflammatory factors.
A systematic review and meta-analysis of observational studies was conducted to summarize the findings on the association between dietary intakes of selected food groups and nutrients (dairy, fats, fruits, vegetables, legumes, and animal-derived protein sources), and the risk of endometriosis among adult women. A higher intake of total dairy was associated with decreased risk of endometriosis. Increased risk of endometriosis was associated with higher consumption of red meat, trans fatty acids (TFA), and saturated fatty acids (SFA). The results of this meta-analysis suggest that there may be differing associations between dietary intake of dairy foods, red meat, SFAs, and TFAs and the risk of endometriosis.
