Coconut oil is being heavily promoted as a healthy oil, with benefits that include support of heart health. To assess the merits of this claim, the literature on the effect of coconut consumption on cardiovascular risk factors and outcomes in humans was reviewed. Twenty-one research papers were identified for inclusion in the review: 8 clinical trials and 13 observational studies. The majority examined the effect of coconut oil or coconut products on serum lipid profiles. Coconut oil generally raised total and low-density lipoprotein cholesterol to a greater extent than cis unsaturated plant oils, but to a lesser extent than butter. The effect of coconut consumption on the ratio of total cholesterol to high-density lipoprotein cholesterol was often not examined. Observational evidence suggests that consumption of coconut flesh or squeezed coconut in the context of traditional dietary patterns does not lead to adverse cardiovascular outcomes. However, due to large differences in dietary and lifestyle patterns, these findings cannot be applied to a typical Western diet. Overall, the weight of the evidence from intervention studies to date suggests that replacing coconut oil with cis unsaturated fats would alter blood lipid profiles in a manner consistent with a reduction in risk factors for cardiovascular disease.
椰子油正被大力宣传为一种健康的油,其益处包括有助于心脏健康。为了评估这一说法的价值,我们查阅了关于食用椰子对人类心血管危险因素和结果影响的文献。共确定了21篇研究论文纳入该综述:8项临床试验和13项观察性研究。大多数研究考察了椰子油或椰子制品对血清脂质谱的影响。与顺式不饱和植物油相比,椰子油通常会使总胆固醇和低密度脂蛋白胆固醇升高的幅度更大,但比黄油小。食用椰子对总胆固醇与高密度脂蛋白胆固醇比值的影响通常未作考察。观察性证据表明,在传统饮食模式下食用椰肉或椰汁不会导致不良心血管后果。然而,由于饮食和生活方式模式存在巨大差异,这些发现不能应用于典型的西方饮食。总体而言,迄今为止干预研究的证据表明,用顺式不饱和脂肪替代椰子油会改变血脂谱,其方式与降低心血管疾病危险因素相一致。
