At Morocco Gold, we love keeping an eye on the most recent research on the health benefits of extra virgin olive oil.
To keep it digestible for all, we’ve pulled out the top five key findings from a new 2026 study highlighted by Verywell Health that explains the positive impact olive oil can have on our brains.
This new study suggests a possible relationship between virgin olive oil consumption, cognitive function and the gut microbiome, adding to growing research into the gut–brain axis. And for a premium, high‑polyphenol oil like Morocco Gold, these findings resonate even more strongly.
Below are the top five takeaways from the research — and how they connect to Morocco Gold’s quality, purity, and health‑forward profile.
What Did The 2026 Olive Oil And Brain Health Study Find?
The study followed 656 adults aged 55 to 75 over two years and found that higher consumption of virgin olive oil was associated with better preservation of cognitive function and greater gut microbiota diversity. The researchers also identified changes in gut bacteria that may help explain the association.

| Age | 55–75 years |

| Important limitation | Observational study — it cannot prove cause and effect |
1. Extra Virgin Olive Oil Supports Better Cognitive Function
The study found that older adults who consumed more extra‑virgin olive oil performed better on cognitive tests. This aligns with long‑standing evidence that EVOO is a cornerstone of the Mediterranean diet, which is consistently linked to healthy aging and sharper brain function.
Morocco Gold’s high polyphenol levels (typically 600+ mg/kg) make it an ideal choice for those looking to incorporate brain‑supportive EVOO into their daily routine. Just remember this simple equation: higher polyphenols = stronger antioxidant activity = better long‑term protection for brain cells.
2. The Gut–Brain Axis Is a Key Mechanism
One of the most exciting findings is that EVOO consumption was associated with greater gut microbial diversity — a marker of a healthier microbiome. A more diverse gut ecosystem is increasingly understood to influence inflammation, metabolism, and even cognitive performance.
Morocco Gold is packed with healthy polyphenols.
Because Morocco Gold is a single‑estate, early‑harvest oil, it retains more of the natural phenolic compounds that appear to support gut health. Its purity means no blends, no refining, and no loss of the compounds that nourish beneficial gut bacteria.
3. Phenolic Compounds Are An Important Area Of Research
The study highlights three key phenolics: hydroxytyrosol, tyrosol, and oleocanthal. These compounds act as antioxidants and anti‑inflammatories, helping protect brain cells from oxidative stress — a major contributor to cognitive decline.
Morocco Gold is specifically celebrated for its oleocanthal content, which gives the oil its signature peppery finish. That “bite” is more than flavour — it’s a sign of potent anti‑inflammatory activity like ibuprofen, but naturally occurring.
4. The Study Is Observational — But Still Meaningful
Researchers emphasise that the study cannot prove causation. However, the associations are strong and consistent with decades of Mediterranean diet research. It’s an important early step in understanding how Extra Virgin Olive Oil interacts with the microbiome to influence brain health.
When evidence is still emerging, quality matters even more. Choosing a premium EVOO with verified lab results — like Morocco Gold — ensures you’re consuming the phenolic-rich oil used in most scientific studies, not a refined or diluted alternative.
5. The “Effective Dose” Is Achievable
Cognitive benefits increased with each additional 10 grams of EVOO consumed, up to 53 grams per day (around four tablespoons). This is easily incorporated into everyday meals: drizzling, dressing, sautéing, or finishing dishes.
Morocco Gold’s smooth, well‑balanced flavour profile makes it ideal for daily use. Whether poured over roasted vegetables or used in a simple vinaigrette, it elevates both taste and nutritional value.
What Does This Research Mean For Consumers?
This research adds to growing interest in the relationship between virgin olive oil, the gut microbiome and cognitive health. The findings are particularly interesting because they suggest the gut microbiota may be one of the mechanisms involved in the association between virgin olive oil consumption and cognitive function.
However, the researchers are clear that further studies are needed. The findings should therefore be viewed as another useful piece of evidence rather than proof that consuming extra virgin olive oil will prevent cognitive decline.
Morocco Gold is a single-estate extra virgin olive oil with a latest measured polyphenol level of 606mg/kg, providing consumers with transparent information about the composition of the oil they are choosing.
