New Study Shows Biophenols Present In Extra Virgin Olive Oil Can Benefit Those With Obesity And Prediabetes
Consuming plenty of Extra Virgin Olive Oil, packed with the polyphenols Oleocanthal and Oleacein can improve health outcomes for people with obesity and prediabetes, a new study has shown.
According to the new study, published in Clinical Nutrition, consuming extra virgin olive oil rich in these biophenols for one month increased blood antioxidant defenses and decreased parameters associated with oxidative stress and inflammation, underlying conditions of both prediabetes and obesity.
According to a summary of the study reported in Olive Oil Times, these benefits were not observed after the consumption of non-virgin olive oil – a mixture of refined olive oil and some virgin olive oil – over the same period.
The research – known as the APRIL (Aove in PRedIabetes) study – saw 91 participants from Málaga, Spain, aged 40 to 65, with obesity and prediabetes divided into two groups.
One group of participants consumed the biophenol-rich extra virgin olive oil, and the other group consumed the non-virgin olive oil for 30 days. After a washout period of 15 days, each group received the other type of oil and consumed it for another 30 days. Both oils were consumed cooked and raw, but the exact amount of consumption was not measured.
Francisco-Javier Bermúdez-Silva, the study’s corresponding author and senior researcher at the Regional Hospital of Málaga, told Olive Oil Times.
“The main finding was the changes in oxidative stress. We found a better antioxidant profile and detected a decrease in some enzymes that are relevant for oxidative stress. Lipid peroxidation is a common feature of oxidative stress, and we found that these people had less oxidation of their lipids in the blood, this is in line with all the previous basic research that had been done with these polyphenols.”

According to study researchers, three key compounds were identified as primarily responsible for reduced inflammation after consuming the extra virgin olive oil. As the study notes, extra virgin olive oil suggests “a higher capacity to modulate systemic inflammation when compared to olive oil.”
“Oleocanthal and oleacein could be mediating this latter effect because their anti-inflammatory actions are well-documented,” the researchers added.
Links Between Obesity And Inflammation And How Extra Virgin Olive Oil Can Help.
Obesity is a major health issue in today’s society and is strongly associated with chronic diseases and metabolic syndrome, including cardiovascular disease and diabetes mellitus. The excess fat tissue in obese individuals acts as a site of inflammation, releasing proinflammatory cytokines and disrupting the body’s natural processes.
Maintaining a healthy diet with healthy fats is essential for good health. Incorporating high-quality olive oil with anti-inflammatory properties into the Mediterranean diet is an effective way to promote human health and reduce the risk of inflammatory biomarkers.
Bermúdez said there is a growing consensus that oxidative stress precedes the development of inflammation.
“This low-grade inflammation is related to insulin resistance, Insulin resistance is related to failing the beta cells to produce enough insulin, and this leads to hyperglycemia and later to a state in which the body cannot control glucose levels in the blood. The oxidative stress and inflammation are boosting all of these diseases, If you consume these compounds in extra virgin olive oil, we hypothesized that you can improve your condition and prevent the development of diabetes. To some extent, this is what we found.”

However, Bermúdez acknowledged several limitations to the study that should be improved with further human studies, including the smaller-than-expected sample size and relatively short time frame, which prevented researchers from following the clinical evolution of the patients.
“If we could follow these patients for longer, I guess that we would find less diabetes, less obesity and better general health,” he said.
Why Choose Extra Virgin Olive Oil Instead Of Non-Virgin Olive Oil?
Extra virgin olive oil has long been recognised for its medicinal properties and as a staple in the Mediterranean diet. Its benefits are numerous, and research supports olive oil consumption as part of primary prevention strategies for those at risk of obesity and metabolic syndrome.
What sets it apart from other olive oil is its higher phenolic content, superior phenolic composition, and health promoting properties. These compounds reduce tumor necrosis factor alpha and c reactive protein, helping the body maintain a stable inflammatory status and support lipid metabolism.
International Olive Council standards ensure that cold-pressed extra virgin olive oil retains its nutritional value and unique anti-inflammatory profile.
However, the researchers added that they did not observe changes in insulin resistance, lipid profile, blood pressure or renal function.
“Taken together, these findings suggest that extra virgin olive oil was able to induce some clinical improvement in glucose handling, probably related with body weight decrease and amelioration of the inflammatory and oxidative status.
This was really a surprise for us. In one month, we didn’t expect to see a change in body weight or a change in glycemia, but these are very good indicators of good clinical results for these types of patients.”

Bermúdez added that he is working on a new study to determine how oleocanthal and oleacein consumption may affect people with diabetes.
“We have a new project in mind in which we plan to perform a similar study, but on people with diabetes,” he concluded.
“Our study has shed some light on the prevention side of this compound. Now what we want to do is to perform a more therapeutic study by seeing what is happening in people who are already diabetic.”
Morocco Gold Extra Virgin Olive Oil Polyphenols
The polyphenol content of Morocco Gold extra virgin olive oil is exceptional, making it a standout, polyphenol-rich olive oil from Africa for weight loss. Three key factors contribute to this:
- The Picholine Marocaine variety, known for its potent fatty acid profile and high phenolic olive oils.
- The climate and terroir of Morocco.
- The early harvest of olives, which maintains a higher phenolic content.
The result is a high quality olive oil with beneficial effects on human health, including improving insulin sensitivity, supporting liver function, and reducing inflammatory biomarkers.
We are proud to say this year’s harvest produced our highest polyphenol levels yet, reinforcing Morocco Gold as a leading choice for primary prevention of cardiovascular disease, weight gain, and insulin sensitivity challenges.
