剥香蕉的时候，你有没有为里面的韧丝烦恼过？直接扯掉还是吃了？有没有想过香蕉为什么要长这些韧丝呢？美国学者表示，这些韧丝是为了传输营养物质而存在，完全可以食用，而且也同样富含营养。 Bananas are a wonderful source of potassium and are the perfect on-the-go snack. 香蕉是钾元素的绝佳The only downside to the fruit are those irritating leathery strands - which are actually called 'phloem bundles' - that you get when you peel back a banana skin. 唯一的缺点是剥开香蕉皮时让人厌烦的韧丝，其实这是“韧皮束”。 But while those stringy bits may not be the most palatable, they are in fact very important - and we wouldn't be able to eat bananas without them, according to Nicholas D. Gillitt, a US academic who shed some light on the mystery this week in a report by Huffington Post. 根据美国学者尼古拉斯•D•吉略特所言，尽管这些韧丝可能不是最美味的，但其实它们很重要。没有它们的话我们就无法吃到香蕉。本周在《赫芬顿邮报》的一篇报道中，他向大家揭开了这一秘密。 The clue as to why those strands are so important is in their name. 为什么这些韧丝如此重要？答案就隐藏在名字里。 Phloem is one of two types of transport tissue that you can find in all plants, and moves nutrients and other substances around the whole plant. |
