Initially, American oncologists identified EVOO as a preferred cooking oil for cancer prevention. Experts noted that while genetics and environment play roles, a healthy diet can reduce cancer risk by approximately 30-40%. Medical professionals emphasized that diet is a critical component of prevention alongside managing obesity and physical activity. Subsequent reports expanded on these benefits, noting that the oil is rich in monounsaturated fats and polyphenols. These compounds are studied for their ability to reduce inflammation and potentially protect neural pathways against cognitive decline, offering benefits for heart, brain, and digestive health. While some wellness trends suggest specific mixtures, such as EVOO and lemon juice for liver cleansing, specialists warn these are not medical treatments and should not replace professional advice. ## Timeline ### 2026-09-05: Extra virgin olive oil offers heart and brain health benefits Nutritionists recommend extra virgin olive oil for heart and brain health due to its polyphenols, though they warn against unproven 'liver cleansing' trends involving lemon juice mixtures. 2 sources. https://clstr.news/cluster/extra-virgin-olive-oil-offers-heart-and-brain-health-benefits ### 2026-08-10: Extra-virgin olive oil preferred by US oncologists for cancer prevention American oncologists recommend extra-virgin olive oil as a preferred dietary choice to help reduce cancer risks alongside a high-fiber, plant-based diet. 2 sources. https://clstr.news/cluster/extra-virgin-olive-oil-preferred-by-us-oncologists-for-cancer-prevention --- Cite as: Health benefits of extra-virgin olive oil.
