This study examines, for the first time, the effect of hybrid Elaeis oleifera × E. guineensis palm oil supplementation on human plasma lipids related to CVD risk factors. One hundred sixty eligible participants were randomized and assigned to one of the two treatments: 25 mL hybrid palm oil (HPO group) or 25 mL extra virgin olive oil (EVOO group) daily for 3 months. Fasting venous samples were obtained at baseline and after 1, 2 and 3 months for measurement of plasma lipids (TC, LDL-C, HDL-C and TAGs). Changes in body mass index and waist circumference were also assessed. Although there was an overall reduction in TC (7.4%, p < 0.001) and in LDL-C (15.6%, p < 0.001), no significant differences were found between the treatment groups in a repeated measures analysis of variance for TC (p = 0.0525), LDL-C (p = 0.2356), HDL-C (p = 0.8293) or TAGs (p = 0.3749). Furthermore, HPO consumption had similar effects on plasma lipids to EVOO, thus providing additional support for the concept that hybrid Elaeis oleifera × E. guineensis palm oil can be seen as a "tropical equivalent of olive oil".
本研究首次考察了油棕（Elaeis oleifera）与非洲油棕（E. guineensis）杂交种棕榈油补充剂对与心血管疾病风险因素相关的人体血脂的影响。160名符合条件的参与者被随机分为两组接受以下两种治疗之一：每天服用25毫升杂交棕榈油（HPO组）或25毫升特级初榨橄榄油（EVOO组），持续3个月。在基线以及1、2和3个月后采集空腹静脉血样，以测量血脂（总胆固醇、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇和甘油三酯）。还评估了体重指数和腰围的变化。尽管总胆固醇（7.4%，p<0.001）和低密度脂蛋白胆固醇（15.6%，p<0.001）总体上有所降低，但在重复测量方差分析中，治疗组之间在总胆固醇（p = 0.0525）、低密度脂蛋白胆固醇（p = 0.2356）、高密度脂蛋白胆固醇（p = 0.8293）或甘油三酯（p = 0.3749）方面未发现显著差异。此外，食用杂交棕榈油对血脂的影响与特级初榨橄榄油相似，从而为油棕（Elaeis oleifera）与非洲油棕（E. guineensis）杂交种棕榈油可被视为“热带橄榄油”这一概念提供了更多支持。
