Background/Objectives: This study investigates the association between extra virgin olive oil (EVOO) consumption and mortality risk in a cohort of Italian adults adhering to the Mediterranean diet. Methods: In a 17-year follow-up study involving participants from Castellana Grotte, Italy (2005–2023), we analyzed dietary intake and mortality data. Participants were categorized into three EVOO consumption groups: <30 g/day, 30–50 g/day, and >50 g/day. Mortality Hazard Ratios (HR) and Subdistribution Hazard Ratios (SHR) were calculated to assess the relationship between EVOO intake and all-cause and cancer mortality. Results: Higher EVOO consumption was associated with significantly reduced cancer and all-cause mortality. Specifically, the daily intake of 30–50 g of EVOO was linked to a 24% lower risk of all-cause mortality (HR 0.77; 95% CI 0.63–0.93), while the consumption of more than 50 g/day was associated with a 20% reduction (HR 0.80; 95% CI 0.65–0.98). The most pronounced benefit was observed for gastrointestinal cancers, with a 60% lower mortality risk for those consuming over 50 g/day (SHR 0.39; 95% CI 0.21–0.73). A 50% reduction in mortality risk from other cancers was also noted for the highest consumption category (SHR 0.50; 95% CI 0.31–0.81). Conclusions: The findings support the beneficial role of EVOO in reducing cancer mortality, particularly with higher consumption levels. The results underscore EVOO’s potential as a dietary intervention for cancer prevention, aligning with the Mediterranean diet’s overall health benefits. Further research is needed to confirm these findings and explore the underlying mechanisms.
**背景/目的:** 本研究旨在探讨遵循地中海饮食的意大利成年人群中,特级初榨橄榄油摄入量与死亡风险之间的关联。 **方法:** 在一项针对意大利卡斯泰拉纳-格罗泰地区参与者(2005–2023年)进行的为期17年的随访研究中,我们分析了膳食摄入量和死亡率数据。参与者根据EVOO摄入量分为三组:<30克/天、30–50克/天和>50克/天。计算死亡率风险比和竞争风险模型下的亚分布风险比,以评估EVOO摄入量与全因死亡率及癌症死亡率之间的关系。 **结果:** 较高的EVOO摄入量与癌症死亡率和全因死亡率的显著降低相关。具体而言,每日摄入30–50克EVOO与全因死亡风险降低24%相关,而每日摄入超过50克则与风险降低20%相关。最显著的益处体现在胃肠道癌症方面,每日摄入超过50克EVOO的参与者其死亡风险降低了60%。在最高摄入量组中,其他癌症的死亡风险也降低了50%。 **结论:** 研究结果支持EVOO在降低癌症死亡率,尤其是在较高摄入水平时的有益作用。这些结果强调了EVOO作为癌症预防膳食干预措施的潜力,这与地中海饮食的整体健康益处相一致。需要进一步的研究来证实这些发现并探索其潜在机制。
