In a Few Words:
Olive oil, especially high-polyphenol extra virgin olive oil, plays a meaningful role in women’s health by supporting hormonal balance, reducing inflammation, and improving heart, skin, bone, and reproductive health over time. The key takeaway is that quality and consistency matter far more than occasional use, with higher-polyphenol oils delivering the benefits most research actually points to.
Greek women have one of the highest life expectancies in Europe. Ask yiayia why and she won't mention any studies, polyphenols, or famous nutritionists - she'll just point at the olive oil and keep cooking. We think she's onto something.
It's only recently that nutritional science has started to catch up with what’s been happening in Mediterranean kitchens for years - particularly around a group of plant compounds in olive oil called polyphenols, and what they actually do in the body.
But most of the conversation around it still stays generic (heart health, Mediterranean diet, good fats) without really looking at how women’s bodies change over time. The reality is, the way a body responds to inflammation, oxidative stress, and hormonal changes in your 30s isn’t the same as in your 40s or 50s. Hormones fluctuate, inflammation can build more easily, recovery slows, and the small, daily inputs start to matter more.
And while olive oil gets talked about as a general “healthy choice”, the broader olive oil benefits for women - particularly the role of high-polyphenol extra virgin olive oil (EVOO) - rarely get a proper look in. That’s surprising when you consider how often they show up across research into hormones, inflammation, and long-term disease risk.
This article breaks down the benefits of olives for females - including what the research actually shows, why quality matters more than most people realise, and how to make the most of it day to day.
Why olive oil matters for women's health
To see why olive oil is more than just a “healthy fat,” it helps to look at how dietary fat actually works in the female body.
Hormones such as oestrogen, progesterone, and cortisol rely on fats as building blocks. The fats you eat shape how the body produces and manages these hormones, which affects overall hormonal balance.
When that balance is disrupted, it shows up in ways many women recognise:
-
Cycle changes
-
PMS
-
Changes in mood
-
Breakouts or skin flare-ups
-
Sleep disturbances
-
Fluctuating energy levels
-
Increased cravings, especially for sugar or carbs
-
Bloating or digestive changes
-
Headaches or migraines
Olive oil is packed with oleic acid, a monounsaturated fat that helps keep cell membranes healthy and supports the body in reducing chronic, low-grade inflammation.
That inflammation matters more than you’d think, despite the name. An increasing amount of studies have found that it's linked to hormonal disruption, cardiovascular risk, metabolic changes, and faster biological ageing. All of these influence how the body functions over time - and diet is one of the most effective ways to influence it.
Then there are the polyphenols. The health benefits of polyphenols like oleocanthal and oleuropein are well-evidenced - they're naturally occurring plant compounds with antioxidant and anti-inflammatory properties, and top-quality EVOO is rich in them. Not all olive oils carry the same polyphenol levels - the production process matters, as does timing.
We’ve covered the details of polyphenol levels and how to judge them in our guide to high-polyphenol olive oil in the UK, so here we’ll focus on why they matter specifically for women’s health.
The key health benefits of olive oil for women
Wondering how olive oil can improve women’s health? Let’s take a look at the benefits of olives for females in more detail.
Supports hormonal balance
Because fat is the raw material for hormone production, the quality of that fat matters.
In a 2026 randomised controlled trial from the University of Vermont Larner College of Medicine, women who consumed 40g of EVOO per day for eight weeks showed improvements in insulin sensitivity and inflammation - both key regulators of hormone signalling and function.
For women dealing with PMS, hormonal acne, or irregular cycles, this research matters. It adds to a growing body of evidence showing Mediterranean-style diets can support women’s metabolic and hormonal health. Diet isn’t everything, but it’s one of the most practical and impactful things you can control.
Helps reduce chronic inflammation
Oleocanthal, one of the main polyphenols in olive oil, has been shown in lab studies at the Monell Chemical Senses Centre in Philadelphia to target the same inflammation pathways as ibuprofen - just at a lower, dietary level.
This is something we actually covered in our article on olive oil and arthritis.
More recently, the APRIL randomised crossover trial run by the University of Jaén in Spain found that adults with obesity and prediabetes who consumed EVOO rich in the oleocanthal and oleacein polyphenols saw improvements in inflammation and antioxidant status compared to those given a standard olive oil.
Polycystic ovary syndrome (PCOS) affects around 5-13% of women in their 20s and 30s. It’s closely linked to hormonal imbalance and ongoing low-level inflammation, with many studies showing higher levels of inflammation in women living with the condition.
While olive oil isn’t a treatment for PCOS, including high-quality EVOO as a regular fat source can help support a diet aimed at reducing inflammation - something current guidance already leans on alongside medical and lifestyle support.
Supports heart health, especially post-menopause
After menopause, the risk of heart disease increases. Oestrogen’s protective effect on blood vessels drops, LDL cholesterol tends to rise, and arteries become less flexible. As that change happens, diet becomes one of the more practical ways to influence long-term heart health.
This is where the connection between olives, cholesterol, and cardiovascular health starts to matter. EVOO combines monounsaturated fats with polyphenol antioxidants - a combo that’s been consistently linked to better cholesterol balance, lower oxidative stress in blood vessels, and reduced cardiovascular risk.
The evidence backs it.
A 2024 meta-analysis led by researchers at the Chinese Academy of Medical Sciences linked higher olive oil intake with lower cardiovascular risk and overall mortality. There’s also the PREDIMED trial, a large, multi-centre study in Spain, which found that adding EVOO to a Mediterranean-style diet significantly reduced major heart problems.
May support fertility and reproductive health
The pre-conception period is one where dietary fat quality appears to matter. Research from cohort and IVF studies links fat type with fertility outcomes, including egg quality and treatment success. This likely comes down to both cell health and inflammation levels in the body, and it's part of why olive is good for pregnancy preparation.
In practice, Mediterranean-style diets, where olive oil is a main fat, are linked with better reproductive outcomes in real-world studies.
But there’s also clinical evidence behind this. Research from the Harvard School of Public Health found that women undergoing IVF with the highest intake of monounsaturated fats had more than three times higher odds of a successful pregnancy, compared with those with the lowest intake. And a study from the University of Athens, published in Human Reproduction, reported similar results: the closer people stuck to a Mediterranean diet, the better their IVF success rates.
It’s still a developing area of research, but the pattern is clear enough: The fats you use seem to matter, and extra virgin olive oil fits naturally into it.
Contributes to bone health over time
Bone density starts to decline from the 30s and tends to drop more sharply around menopause, when lower oestrogen increases the risk of osteoporosis.
Research has found that the polyphenols in EVOO may help by reducing oxidative stress and supporting the balance between bone breakdown and formation. In the same PREDIMED trial we talked about earlier, researchers found that women with higher olive oil intake had stronger bone structure and signs of better bone health than those who ate less.
Now we’re not saying that EVOO is a replacement for calcium or vitamin D - but it fits well within a diet that supports long-term bone health.
Supports skin health and the ageing process
When it comes to olive oil benefits for skin, it all starts inside the body. Skin ageing is partly driven by oxidative stress - a build-up of damage in skin cells over time. EVOO contains antioxidants like vitamin E and polyphenols, which help the body reduce this damage and keep inflammation in check.
But this is about what you eat, not what you put on your skin. When consumed, these compounds circulate in the body and, in research, have been shown to reduce oxidative damage and support collagen and elastin (the proteins that keep skin firm) while also slowing down processes that break them down.
Lower inflammation and reduced cell damage are both linked with healthier, more resilient skin over time, which is why olive oil is often seen as part of a skin-supportive diet.
How to use olive oil daily for health benefits
A daily amount of around one to two tablespoons of EVOO is a solid, scientifically-backed range, best spread across meals rather than taken all at once.
What matters most, though, is consistency: the benefits seen in studies build gradually over time, through regular use - not from the occasional extra drizzle on dinner once a week.
If you want to preserve more of the beneficial compounds, extra virgin olive oil is best used raw where possible - drizzled over salads, vegetables, or finished dishes just before serving. It can still be used for cooking, but higher temperatures reduce some of its more delicate compounds - so save your top oils for finishing.

What yiayia knew
Olive oil isn’t a supplement, and it isn’t a cure. But used regularly, as part of a diet that pays attention to fat quality, it offers well-evidenced support across different stages of women’s health - from hormones and inflammation in younger years, to heart and bone health later on.
Step back, and it’s clear the benefits of olives for females are the result of small, steady habits building up over time. Turns out yiayia was right all along - the science just took a while to catch up.
The quality of the oil matters as much as the habit. A lot of olive oil’s benefits come down to its polyphenol content, and that can vary a lot from bottle to bottle.
If you're looking for a starting point, both Masworth and November EVOO are independently lab-tested at 965mg/kg and 1200mg/kg respectively - well above the threshold where these benefits have been studied.

FAQs
How much olive oil should a woman consume daily?
One to two tablespoons (15-30ml) per day is what the science supports. This can be spread across meals, used as a dressing, or used in cooking at low to medium heat.
Is olive oil good during menopause?
Yes - after menopause, heart health becomes more of a focus, and bone density naturally declines faster. Olive oil’s mix of healthy fats and antioxidants supports both, and it’s one of the more evidence-backed dietary shifts at this stage of life.
Can olive oil help with hormones?
Dietary fat plays a role in hormone production, and the quality of fat matters. The main fat in olive oil, oleic acid, supports healthy cell function, while its polyphenols help keep inflammation in check - both of which are relevant for hormonal balance. It’s a supportive food, not a treatment.
Does olive oil help with PCOS?
PCOS is linked with ongoing low-level inflammation, and diet is often part of managing it. Olive oil contains compounds like oleocanthal that have shown anti-inflammatory effects in research, making it a useful addition to a PCOS-friendly diet alongside medical advice.
Is all extra virgin olive oil the same?
Polyphenol levels vary a lot depending on when the olives are harvested, how the oil is extracted, and how it’s stored. Fresh, early-harvest, cold-pressed oils tend to have the highest levels, while many supermarket oils contain much less - even if they’re labelled extra virgin.
