最新一项研究可能能够为那些喜爱奶油制品的朋友们带来积极的消息了:研究者们发现平时吃较多的奶油制品体脂率以及BMI等值反而会偏低。

这项研究可能会与我们平常了解的不太一样:如果想要保持健康,那么黄油、起司、奶油等富含饱和脂肪酸的食物还是少吃为妙。此外,血液中低密度脂蛋白胆固醇的含量上升会提高患血管疾病的风险。

然而,这项由爱尔兰研究者们作出的研究则表明:起司等高脂肪奶制品并不是威胁健康的有害食物。"根据我们的发现,平时购买奶油量较大的消费者相比其他群体摄入饱和脂肪酸的水平也明显偏高的,但是两个群体之间的血液低密度脂蛋白以及胆固醇的含量并没有明显的变化"。

在这项研究中,研究者们对爱尔兰境内18到90岁之间的500名志愿者进行了为期四天的观察。观察内容包括他们的日常饮食,食用的奶制品的类型以及是否属于脱脂等等。

"摄入奶制品量较高的人体脂率以及BMI指数都相对偏低,其体内胰岛素的敏感度也相对偏高"。研究者们还发现,经常性食用酸奶的人群体脂率最低,而食用奶油量最高的人群没有表现出任何代谢相关疾病的指标异常现象。

那么这是为什么呢?原因可能还比较复杂。

我们都知道相关性不代表存在因果关系。因此食用低脂食物的同时应该还食用了别的东西导致血液中胆固醇含量上升。另外,食谱中奶制品的出现与否多少也会影响整理食谱的结构。因此,科学家们并不确定禁食是最好的缓解代谢疾病的方法。针对这一问题还需要更多的研究加以确定。不过,就现在而言,我们可以开心地先吃点奶酪,而不必过分地内疚了。

相关研究结果发表在《Nutrition & Diabetes》杂志上。
