Oleanolic Acid-Enriched Olive Oil Attenuates Kidney Function Decline in Patients With Type 2 Diabetes: Results From the OLTRAD Randomised Controlled Trial.

Article B Peer reviewed Small trial

Key takeaways

In a randomized trial, people with type 2 diabetes used olive oil enriched with oleanolic acid, a natural compound from olives. This extra analysis found their kidney filtering rate (eGFR) dropped more slowly over long-term use. It was a smaller, planned side-analysis of the main trial, and the abstract does not give the exact number of people, so treat it as early evidence, not final proof.
