Extra virgin olive oil (EVOO), a cornerstone of the Mediterranean diet, has become the focus of a study that highlights its neuroprotective and anti-inflammatory potential. A team of researchers from CIDAF, the “José Mataix Verdú” Institute of Nutrition and Food Technology, and the University of Granada, Spain, analyzed the content of phenolic compounds in EVOO from two Protected Designations of Origin (PDO) and their relationship with the inhibition of key enzymes in neurodegenerative processes.
The study focused on characterizing 15 EVOO samples, using liquid chromatography coupled with mass spectrometry (HPLC-MS) to identify and quantify the phenolic compounds present. Among the most relevant compound families are phenolic alcohols, secoiridoids, lignans, flavonoids, and phenolic acids.
The researchers evaluated the ability of EVOO to inhibit two crucial enzymes in the development of neurodegenerative and inflammatory diseases: acetylcholinesterase (AChE) and cyclooxygenase-2 (COX-2). For this, spectrophotometric and fluorimetric assays were used. The results revealed that EVOO samples with the highest concentration of phenolic compounds and inhibitory activity were those of the Picual and Manzanillo varieties.
Statistical analysis showed a positive correlation between the content of phenolic compounds and the inhibition of AChE and COX-2 enzymes, except for lignans. These findings reinforce the neuroprotective potential of EVOO, confirming its benefits beyond the nutritional realm.
The study highlights the variability in phenolic composition among the different PDOs of Granada, showing statistically significant differences. This discovery underscores the importance of the origin of EVOO in determining its biological properties.
While the results are promising, the researchers emphasize the need for additional studies to delve deeper into the relationship between phenolic compounds, PDOs, and the neuroprotective potential of EVOO. Expanding the sample to more EVOO varieties will strengthen the conclusions and offer a more complete view of their health benefits.
“Our findings reaffirm that EVOO, rich in phenolic compounds, has considerable neuroprotective and anti-inflammatory potential,” says one of the lead researchers of the study. “These results reinforce the hypothesis that phenolic compounds are essential in the prevention of neurodegenerative diseases, opening new opportunities for their therapeutic use.”
In Conclusion
EVOO is positioned as a natural shield for the brain, thanks to its richness in phenolic compounds and its ability to inhibit key enzymes in neurodegenerative processes. Continued research will allow us to fully explore the beneficial properties of this precious food and its potential to protect our health.
