Study
The researchers had an idea of their study participants' olive oil intake. They divided the participants into two groups—one group consuming less than four tablespoons of extra virgin olive oil daily and one group consuming four or more tablespoons daily.
The two groups differed little from each other. They had roughly the same lifestyle, BMI, and weight.
The study participants completed a standardized questionnaire regarding physical health. The questions asked about [1] how well the study participants could perform physical activities such as walking, climbing stairs, and lifting; [2] whether they could work, cook, and keep their house tidy; [3] whether they experienced pain; and [4] whether they felt healthy.
Results
In the group with the lower extra virgin olive oil [EVOO] intake, the total [Comp-P] score decreased as the study participants got older. This association was not observed in the group with the higher intake. Aging did not appear to correlate with decreased subjective physical health.

Conclusion
"Promoting regular extra virgin olive oil consumption within the Mediterranean diet could represent a simple and sustainable public health strategy to support healthy aging, aligning with current efforts to extend both life expectancy and years lived in good health and functional independence", the Spanish write.
The researchers, incidentally, were not funded by the olive oil industry or the Spanish Ministry of Agriculture, but by the Ministry of Sport and their university.
