Avocados have been showing up everywhere the past few years -- on menus, in beauty products, and on the many lists of superfoods you should be eating, like, starting yesterday. But is this bumpy green fruit really deserving of all the hype? 在最近的几年，牛油果（鳄梨）的身影随处可见，不管是在菜单上，美容产品中，有许多菜单上出现的超级食品，就像是你应该从昨天就开始食用它。但是这个表皮坑坑洼洼的绿色水果真的是实至名归么？ In a word: YES. For starters, they're pretty, but more importantly, they’re extremely good for you. Need more reasons to love avocados? Behold: They've got the good fat 一言以蔽之：是的，对于初次尝试它们的人来说，确实是非常的好，但更重要的是，食用它们会对你的身体非常好。还需要一些喜欢牛油果的理由？那就是：它所含的脂肪都是有益的。 Let's get it out of the way: Avocados are fatty, but not all fats are created equal. The vast majority of the fat in avocados is monounsaturated, which is a polysyllabic way of saying that it can decrease LDL (bad) cholesterol levels and improve overall heart health. 让我们来揭开它的秘密：牛油果富含脂肪，不是所有的脂肪都是一样的。（科普时间到~脂肪由甘油和脂肪酸组成，其中甘油结构简单，为不变量。因此，脂肪因所含脂肪酸种类不同而有所变化，脂肪酸分为饱和脂肪酸和不饱和脂肪酸，其中不饱和脂肪酸又分为单不饱和脂肪酸和多不饱和脂肪酸两类。以上是天然食品中的所含的脂肪酸，还有一类为反式脂肪酸，大多出现在人造食品中。）牛油果所含的绝大部分的脂肪是单不饱和脂肪酸，所以它能够有效的降低体内胆固醇的水平，提升整体健康。 |
