Can olive oil and exercise keep older adults on their feet?
NCT ID NCT07829484
First seen Sep 21, 2026 · Last updated Sep 21, 2026
Summary
Researchers are testing whether a 24-month program of individualized exercise, Mediterranean diet counselling, and daily extra virgin olive oil can improve walking speed and reduce falls in adults aged 75 and older who are frail and at high risk of falling. Participants are randomly assigned to either the full program or exercise alone. The main measure is change in usual walking speed, a key indicator of physical function and fall risk.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A 24-month program combining the VIVIFRAIL multicomponent exercise program, Mediterranean diet counselling, and 60 mL/day of extra virgin olive oil
- What this could lead to
- If it works, this could offer a practical, low-cost way to help frail older adults stay mobile and avoid falls, combining exercise, diet counselling, and olive oil.
- What could go wrong
- The trial is small and relies on participants sticking with exercise and diet changes for two years, which is hard to maintain. Results may not apply to older adults who are less frail or who have different health conditions.
