Does diet influence endometriosis? Definitely yes. The way we eat has an important effect on the symptoms of endometriosis, so proper nutrition is key to managing this condition in the best possible way.
At the Integrative Gynaecology Unit at Clínica Planas, we offer some nutritional advice for endometriosis. Read on to find out which foods you should include in your diet and which ones you should avoid.
What is endometriosis?
Endometriosis is an inflammatory condition with a probable genetic predisposition, in which there is usually a component of low-grade inflammation and excess oestrogen.
When we refer to low-grade inflammation, we mean silent inflammation that is almost always associated with an intestinal problem, although it can also affect other areas. For this reason, it is very important to study the microbiota at oral, intestinal, vaginal and endometrial levels.
How should nutrition be adapted to this condition?
Since we have established that this is an inflammatory condition, we should follow an anti-inflammatory diet. In other words, as we will explore in greater detail later in this article, we should incorporate anti-inflammatory foods into our diet while reducing those that contribute to inflammation.

Foods to include in your diet
Fruit and vegetables
Fruit and vegetables are rich in antioxidants — which help reduce inflammation — provide fibre that helps eliminate excess oestrogen, and contain vitamins A, C and E.
Protein
Adequate protein intake helps regulate hormones and maintain stable energy levels, as well as contributing to tissue repair and helping to control inflammation.
It is important to bear in mind that hormones, the immune system and muscles are made up of proteins. Therefore, if we want to maintain a healthy immune system, balanced hormone levels and adequate muscle mass for healthy longevity, proper protein intake is essential.
Nuts
They provide healthy fats, vitamin E and anti-inflammatory minerals that reduce oxidative stress. They also provide sustained satiety and help regulate the inflammatory response.
Seeds
For example, pumpkin, chia, flax or sesame seeds. They are rich in plant-based omega-3 fatty acids and lignans, which support the regulation of oestrogen metabolism. They also provide soluble fibre, which contributes to hormonal and intestinal balance.
Extra virgin olive oil as a source of healthy fat
A source of oleic acid and polyphenols that help reduce systemic inflammation. It protects cellular health and supports liver function, which is essential for metabolising oestrogen.
And don’t forget proper hydration
Staying properly hydrated helps prevent the increase in cortisol associated with dehydration, thereby reducing the inflammatory burden. It also promotes the elimination of hormonal metabolites and supports healthy intestinal function.
Nickel allergy: Is it related to endometriosis?
Endometriosis is known to be linked to nickel allergy. In clinical practice, it is common to see patients with endometriosis who are allergic to costume jewellery, which is often associated with a nickel allergy.
Nickel is present in many foods, but if we had to highlight those with the highest nickel content, these would include:
- Plant-based foods
- Legumes: including soy, peas and beans, meaning that other legumes could be consumed.
- Certain fruits: pears, cherries and plums, as well as green leafy vegetables, particularly spinach.
