黄油与人造黄油：哪一种对心脏更好？

哪种黄油更有益于我的心脏？黄油还是人造黄油？

对于心脏健康而言，人造黄油通常优于黄油。

人造黄油由主要为不饱和脂肪的多种油混合制成，而黄油则是由奶油或牛奶制成。动物性脂肪（例如奶油）主要为饱和脂肪。

将饱和脂肪替换为不饱和脂肪可降低心血管疾病风险。用植物油中的脂肪替换饱和脂肪可降低体内的总胆固醇和低密度脂蛋白胆固醇（一种“坏胆固醇”）。此发现极有力地证明，相较主要成分为饱和脂肪的油，主要成分为多元不饱和脂肪的油品（例如豆油）更加健康。

但人造黄油也有良莠之分。

美国国外销售的人造黄油可能含有反式脂肪。这类脂肪会增加心脏病风险。美国禁止在国内销售含反式脂肪的人造黄油。

各种人造黄油的饱和脂肪、盐和维生素含量各不相同，具体取决于所用的油和配方。人造黄油越结实，所含的饱和脂肪就越多。人造黄油棒通常比桶装人造黄油含有更多的饱和脂肪。因此，请勿使用人造黄油棒，而应选用软性人造黄油或液体人造黄油。

请选用饱和脂肪含量最少的黄油。最好选择一种饱和脂肪含量低于每日饱和脂肪摄入量 10% 的黄油。您可以在营养标签上看到饱和脂肪含量，并确定哪种黄油的盐含量最低。

您应控制人造黄油食用量，以限制卡路里摄入量。
