Physical activity and Mediterranean diet based on olive tree phenolic compounds from two different geographical areas have protective effects on early osteoarthritis, muscle atrophy and hepatic steatosis

One of the few experiments to test diet and exercise together rather than one at a time, in a surgical OA model with cartilage histology as the endpoint — and it separates the two geographical oil sources, so phenolic content is a variable rather than an assumption.

Population

Rats with anterior cruciate ligament transection, scored by Mankin and OARSI

Intervention

Diet enriched with extra-virgin olive oil and olive leaf extract, combined with physical activity

Comparator

Standard diet, with and without activity

Limitations

Rat model, and diet and activity are combined in the protective arm, so the two contributions cannot be fully separated.
