惊天大逆转!饱和脂肪的摄入并不会增加心脏病的发病风险!

2016-12-28 MedSci MedSci原创

既往众多研究表明饱和脂肪(如奶油和黄油)有害于机体健康,关于这一理论结果的建立已有50多年。但是,近日来自卑尔根大学的一项研究推翻了这一研究结果,该研究结果表明饱和脂肪并不会增加心脏病的发病风险,其研究结果已发表于The American Journal of Clinical Nutrition。研究纳入了38名腹部肥胖的男性以了饱和脂肪的风险。将参与者分为两组,分别为低碳水化合物饮食和低脂肪高

既往众多研究表明饱和脂肪(如奶油和黄油)有害于机体健康,关于这一理论结果的建立已有50多年。但是,近日来自卑尔根大学的一项研究推翻了这一研究结果,该研究结果表明饱和脂肪并不会增加心脏病的发病风险,其研究结果已发表于The American Journal of Clinical Nutrition。

研究纳入了38名腹部肥胖的男性以了解饱和脂肪的风险。将参与者分为两组,分别为低碳水化合物饮食和低脂肪高碳水化合物饮食,为期12周。

然后研究人员测量所有参与者的腹部、肝脏和心脏的脂肪质量。此外,研究人员还评估了参与者的心血管疾病的发病风险因素。

目前关于饱和脂肪的理论表明,高脂肪、低碳水化合物组比低脂肪、高碳水化合物组人群更易患心脏病。然而,事实并非如此,本研究发现两组参与者之间心脏病的发病风险并无明显地组间差异。

高脂肪的摄入并没有增加心血管疾病的风险,在高脂饮食的参与者中几个重要的心血管危险因素也得到了极大的改善,如异位脂肪储存、血压、血脂(甘油三酯)、胰岛素和血糖水平。

该研究所探究的为富含饱和脂肪的新鲜的、低加工和营养食品,包括大量的蔬菜和米饭,而非面粉制品,脂肪的来源也是低加工,主要是黄油,奶油,冷榨油。

两组参与者能量、蛋白质、多不饱和脂肪酸和食物类型相似,主要差异在于数量。添加糖的摄入量保持在最低限度水平。

两组参与者能量的摄入基本在正常范围内。而那些增加能量摄入的参与者仍然可看到发现脂肪储存和疾病风险的降低。

该结果表明,只要脂肪的质量高,总的能量摄入适中,对于大多数健康人来说,摄入较多的饱和脂肪或是无害甚至是有益于健康。

既往研究认为,饱和脂肪促进心脏疾病的发生是由于增加了血液中“坏”低密度脂蛋白(LDL)胆固醇的水平,而本研究结果则否定了这一理论。本研究中,研究人员不仅发现LDL胆固醇没有显著升高,还发现高脂饮食与“好”胆固醇水平的增加无关。

未来仍需更多的研究以确定哪些人群或患者需要限制饱和脂肪的限制,但是,目前来看,高质量脂肪的健康风险确实被夸大了,这对于鼓励公众少食用面粉制品的食物、高加工脂肪食品以及添加糖类食品来说十分重要。
