In recent years, health professionals and laypersons have disseminated misinformation regarding the consumption of coconut oil. Those encouraging the supplementation of coconut oil argue that it provides health benefits and protective cardiovascular effects. Our article examines the effects of coconut oil intake on the cardiometabolic profile by exploring various lipid indices, as well as potential non-lipid effects, such as weight loss. The majority of randomized controlled trials show that coconut oil intake or its supplementation increases low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDLC), and total cholesterol when compared with other vegetable oils. Lauric acid, a medium-chain fatty acid and the main constituent of coconut oil, increases LDL-C and HDL-C concentrations, since it plays a main role as a substrate for apolipoprotein (apo)A1 and apoB synthesis, which are the key molecules in HDL-C and LDL-C particles, respectively.Despite some findings demonstrating an increase in HDL-C, definitive long-term clinical trials are imperative to ascertain whether this effect is clinically relevant. In addition, coconut oil intake has failed as a weight loss strategy and should not be considered as a supplementation strategy to increase satiety and/or thermogenesis.If one desires to include coconut oil in the diet, then we suggest that it should be limited and encompassed within the current recommendations of SFA intake, which are up to 10% of total caloric intake.
近年来,健康专业人士和非专业人士传播了有关椰子油消费的错误信息。那些提倡补充椰子油的人认为它对健康有益,并具有保护心血管的作用。我们的文章通过探讨各种脂质指标以及潜在的非脂质作用(如体重减轻)来研究椰子油摄入对心脏代谢特征的影响。与其他植物油相比,大多数随机对照试验表明,椰子油的摄入或补充会增加低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)和总胆固醇。中链脂肪酸月桂酸是椰子油的主要成分,它增加 LDL-C 和 HDL-C 的浓度,因为它主要作为载脂蛋白(apo)A1 和 apoB 合成的底物发挥作用,apoA1 和 apoB 分别是 HDL-C 和 LDL-C 颗粒中的关键分子。尽管一些研究发现 HDL-C 增加,但需要进行明确的长期临床试验来确定这种影响是否具有临床意义。此外,椰子油摄入作为一种减肥策略已经失败,不应被视为增加饱腹感和/或产热的补充策略。如果有人希望在饮食中加入椰子油,那么我们建议应限制摄入量,并将其包含在当前推荐的 SFA 摄入量内,即总热量摄入的 10%。
