Need glasses? Try kale instead

目力不好?吃羽衣甘蓝尝尝

Do carrots really help you see in the dark? What about kiwis or kale? Can eating certain foods improve your eyesight or prevent your eyes degenerating? Perhaps we should all be taking supplements to benefit our vision? Research in both the US and Ireland has shown that supplementing the diet with certain key chemicals can significantly benefit your vision. These can be taken as supplements but they are also found widely in many green leafy plants and green and yellow fruit and vegetables.

胡萝卜真能明目吗?猕猴桃和甘蓝呢?经过过程吃某些食品能加强目力或许防止目力降低吗?我们是否是应当都吃点以便对我们的目力有益呢?美国和爱尔兰的研究都注解,在饮食中参加某些关键的元素可以明显改良目力。这些成分可以养生片剂弥补,但它们异样广泛存在于很多绿叶植物、绿色和黄色的果蔬中。

The retina is the part of our eye that contains cells sensitive to light. The most delicate area of this tissue - the macula - is protected from harmful blue and UV light by yellowish 'macular pigment'. This acts like sunglasses, blocking the damaging light. It comprises three pigments - lutein, zeaxanthin and meso-zeaxanthin.

视网膜是我们眼睛里的一部分,它有一些对光敏感的细胞构成。视网膜最脆弱的处所是黄斑——“黄斑色素”能保护黄斑不受蓝光和紫外光的伤害。这就像太阳镜一样,可以盖住对眼睛有害的光线。它由三种色素构成——叶黄素,玉米黄质和中玉米黄质。

A research team led by Professor Nolan in Ireland has recently completed a year-long trial investigating the benefits of taking supplements of macular pigments. 100 participants took part in the experiments. The results showed that by taking lutein, zeaxanthin and meso-zeaxanthin, there was a significant improvement in the protection of the macula, as well as in overall eyesight. There was also some evidence that these chemicals can help to slow down macular degeneration, which is the main cause of sight loss in the UK. However, this is somewhat controversial.

爱尔兰诺兰传授带领的研究团队比来完成了一项长达一年的实验。实验研究的是弥补黄斑色素的好处,参与实验的有一百人。实验成果注解,摄取叶黄素,玉米黄质和中玉米黄质能极大年夜晋升视网膜黄斑的保护功能,同时也很大年夜晋升了目力。同时,还有一些证据显示,服用这些化学药物能延缓视网膜的阑珊,而后者却又是英国瞽者中致盲的重要身分。但是,这一实验照样存在一些争议的。

Lutein is a yellow compound found only in plants, which produce it to absorb light. We can get lutein by eating foods like kale and spinach. It is also present in egg yolk. Zeaxanthin, another yellow compound similar to lutein, is found in such foods as corn, yellow bell peppers and saffron. Meso-zeaxanthin is not generally found in food sources, though it can be found in some fish. It is created in the retina from ingested lutein. It can be taken in supplements made with marigold extracts.

叶黄素是一种只存在于植物中的黄色化合物,感化是接收光线。除可以经过过程食用甘蓝菜和菠菜获得这类化合物外,蛋黄中也含有叶黄素。玉米黄质是一种类似于叶黄素的黄色化合物,可以从诸如玉米,黄甜椒和藏红花中获得。中玉米黄质却难以从食品中获得,但有些鱼类体内含有这类物质。视网膜中摄取叶黄素就可以产生中玉米黄质,也能够经过过程食用万寿菊提取物摄取。

As for carrots, it turns out that it's the leafy green bits on the top that contain the key compounds beneficial to eyesight, rather than the vegetable itself. So next time you're told carrots help you see in the dark, save them for the rabbit and chop up some kiwi instead!

至于胡萝卜,证据显示,它的绿叶富含对目力有益的关键化合物,但其本身其实不具有这类功能。所以,下次再有人告诉你说胡萝卜可以晋升目力的时辰,你还不如省着点喂兔子。你可以用猕猴桃取而代之!
