视力不好?吃羽衣甘蓝试试

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?通过吃某些食物能增强视力或者防止视力下降吗?我们是不是应该都吃点以便对我们的视力有益呢?美国和爱尔兰的研究都表明,在饮食中加入某些关键的元素可以显著改善视力。这些成分可以养生片剂补充,但它们同样广泛存在于许多绿叶植物、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组成。视网膜最脆弱的地方是黄斑——“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,可以挡住对眼睛有害的光线。它由三种色素组成——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.

爱尔兰诺兰教授带领的研究团队最近完成了一项长达一年的实验。实验研究的是补充黄斑色素的益处,参与实验的有一百人。实验结果表明,摄入叶黄素,玉米黄质和中玉米黄质能极大提升视网膜黄斑的保护功能,同时也很大提升了视力。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衰退,而后者却又是英国盲人中致盲的主要因素。然而,这一实验还是存在一些争议的。

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,作用是吸收光线。除了可以通过食用甘蓝菜和菠菜获取这种化合物外,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取。中玉米黄质却难以从食物中获取,但有些鱼类体内含有这种物质。视网膜中摄入叶黄素就能产生中玉米黄质,也可以通过食用万寿菊提取物摄入。

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,它的绿叶富含对视力有益的关键化合物,但其本身并不具有这种功能。所以,下次再有人告诉你说胡萝卜可以提升视力的时候,你还不如省着点喂兔子。你可以用猕猴桃取而代之!
