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.
胡萝卜真的能帮助你在黑暗中看到东西吗？弥核桃或者羽衣甘蓝怎样呢？吃某种食物能改善你的视力或者防止你的视力下降吗？也许我们都应该服用某些补充剂来造福我们的视力？在美国和爱尔兰的研究表明，补充某些关键化学品能显著改善你的视力，在很多绿叶植物和绿色黄色水果蔬菜中也发现很多这种化学品元素。
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.
视网膜是我们眼睛的一部分，它含有对光敏感的细胞，该组织最微妙的区域——黄斑——被黄色黄斑色素保护免受有害蓝光和紫外线光的损害。它的作用就如同太阳镜，阻挡有害光，它包含三种天然色素——叶黄素，玉米黄色和消璇玉米黄素。
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.
爱尔兰诺兰教授领导的研究团队最近完成了一项为期一年的调查试验，服用黄斑色素的好处。100个参与者进行了这项试验。结果表明，通过服用叶黄素，玉米黄素和细观玉米黄素，在黄斑的保护以及整体视力上都有显著改善。还有一些证据表明这些化学品有助于减缓黄斑素退化，这是在英国造成视力丧失的主要原因，然而，这有点争议。
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.
叶黄素是一种仅在植物中发现的黄色合成物，它是在植物中产生的，并吸收光，我们通过吃羽衣甘蓝和菠菜可以吸收叶黄素。它也存在于蛋黄中，另一种玉米黄素与叶黄素相似，在玉米，黄椒和藏红花中发现有，在食物中一般没有发现消璇玉米黄质，尽管在一些鱼类里发现有，它是从摄入叶黄素的视网膜中产生的，它可以从万寿菊提取物生产的补充剂里摄取。
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，绿色叶子顶部含有关键合成物，对视力有益，而不是蔬菜本身，所以，下次，别人说胡萝卜有助于你在黑暗中看到东西，告诉他们，把胡萝卜给兔子吃吧，用弥核桃代替吧。
