In 2025, Christos Kourek and team conducted a single-blind randomized clinical trial with 50 hyperlipidemic patients and 20 healthy controls at the General Hospital of Messinia, Greece. Patients were assigned to either 20g/day lower-phenolic EVOO or 8g/day higher-phenolic EVOO for 4 weeks. Lipid profiles were measured at baseline and post-intervention.

In 2025, Éva Szabó from the University of Pécs reviewed 8 studies on how dietary fats affect health. Using trials and meta-analyses, they explored saturated fats (SFAs), trans fats (TFAs), and omega-3s, focusing on obesity, diabetes, heart disease, and gut health in humans and animals.

A 2025 randomized controlled trial in Nutrients by University of Stanford tested omega‑3 supplementation plus resistance training vs. training alone in 30 healthy, active adults.

A 2025 systematic review in Nutrients analyzed clinical and experimental studies, concluding that EVOO consumption is linked to improved cardiovascular health. Its rich content of monounsaturated fats and polyphenols contributes to lowering LDL cholesterol, reducing blood pressure, and enhancing endothelial function.
