1 in 10 women has endometriosis. No calorie tracker was built for them.
Endometriosis isn't just a period problem. It's an inflammatory, hormonal condition that affects what you should eat, how your cycle affects your energy, and what your body needs to manage symptoms. Generic trackers ignore all of this.
How Endometriosis affects what you eat
Endometriosis is an oestrogen-dependent inflammatory condition. Nutrition plays a direct role in symptom management โ an anti-inflammatory diet has been shown to reduce pain scores, while oestrogen-promoting foods can worsen lesion growth. The menstrual phase is the most symptomatic and requires the most nutritional support. Oli is the only tracker that knows where you are in your cycle and adjusts accordingly.
What your body needs most
Directly counter prostaglandin and cytokine activity that drives endo pain. Studies show significant pain reduction with consistent omega-3 intake.
Relaxes smooth muscle, reduces cramping, and improves sleep quality โ all directly relevant to endometriosis symptoms.
Reduce oxidative stress in the peritoneal environment where endometrial lesions develop.
Supports oestrogen clearance through the gut, reducing circulating oestrogen that feeds lesion growth.
Heavy menstrual bleeding is common with endometriosis. Iron replenishment is often chronically needed.
Inhibits NF-ฮบB, a key inflammatory pathway implicated in endometrial lesion development.
Foods to eat more of
Highest dietary source of omega-3s. Anti-inflammatory effects directly counter endo symptoms.
Lignans (phytoestrogens) help balance oestrogen. High omega-3 and fibre content.
DIM supports oestrogen detoxification. Broccoli, cauliflower, Brussels sprouts are ideal.
Curcumin has direct anti-endometrial effects in research. Use with black pepper for absorption.
Iron, magnesium, folate, and antioxidants in one food group.
Concentrated antioxidants with minimal sugar load.
Zinc and magnesium. Anti-inflammatory and supportive of immune function.
Foods to cut back
Associated with higher endometriosis risk in multiple studies. High in omega-6 and heme iron that promotes inflammation.
Raises oestrogen levels and depletes magnesium and B vitamins.
Drive systemic inflammation. Worsen bloating, fatigue, and pain during flare periods.
Associated with increased risk of endometriosis diagnosis in cohort studies.
Phytoestrogens in large amounts may be counterproductive for oestrogen-dominant conditions. Moderate fermented soy (miso, tempeh) is generally well-tolerated.
How your cycle interacts with Endometriosis
Endometriosis symptoms peak during the menstrual phase (days 1โ5) and can worsen in the late luteal phase (days 24โ28). Oli automatically adjusts your targets across all four cycle phases โ not just during your period.
Explore cycle nutrition โEndometriosis, nutrition and your questions
What foods should I avoid with endometriosis?
Cohort studies associate red and processed meat intake with higher endometriosis risk, and researchers point to alcohol (which raises circulating oestrogen), trans fats and refined sugar as drivers of the systemic inflammation linked to pain. These are associations from observational research rather than proven cause and effect โ a registered dietitian can help translate them into an individual plan.
Can diet really reduce endometriosis pain?
Diet cannot cure endometriosis, but studies report lower pain scores with anti-inflammatory eating patterns, and omega-3 intake has been linked to reduced pain in several trials โ researchers attribute this to countering the prostaglandin activity behind cramping. Medical bodies consistently describe nutrition as a complement to medical treatment, not a replacement for it.
What is the best diet for endometriosis?
There is no single named "endo diet" with strong trial evidence. The pattern the research most consistently points to is Mediterranean-style anti-inflammatory eating: fatty fish, plenty of vegetables and fibre (which supports oestrogen clearance through the gut in research), olive oil, nuts and seeds, with limited red meat, alcohol and processed food.
Is dairy bad for endometriosis?
The published evidence doesn't support cutting dairy across the board โ several large studies actually associate dairy intake with lower endometriosis risk. Clinicians note that individual tolerance varies, and typically suggest a structured, time-limited trial with a professional rather than permanent restriction when someone suspects a link.
Should I eat differently during my period with endometriosis?
Researchers describe the menstrual phase as the most symptomatic and nutritionally demanding: menstrual bleeding (often heavy with endometriosis) depletes iron, and omega-3s and magnesium are the nutrients most studied for cramping. Oli raises iron-relevant and anti-inflammatory targets automatically during your menstrual phase.
Important: Nutrition is a powerful tool for managing endometriosis symptoms, but it does not treat or cure the condition. Always work with your gynaecologist, GP, or registered dietitian for a complete management plan.
