VOA慢速英语:Sunshine Can Improve Cancer Odds(翻译)

We should all let the sunshine in as much as possible – and not just because it makes us feel good. Exposure to sunlight produces vitamin D in our skin. This is why we call vitamin D the “sunshine vitamin.”
我们应该尽可能多地让阳光照进来，不只是因为它让我们感到舒服。暴露在阳光下，我们的皮肤就会产生维生素D。这就是为什么我们称维生素D为“阳光维生素”。

Vitamin D is good for everybody. In fact, research shows this “sunshine vitamin” could help women with breast cancer live longer.
维生素D对每个人都有益处。事实上，研究表明这种“阳光维生素”可以帮助患有乳腺癌的女性延长寿命。

Breast cancer patients who have high blood levels of Vitamin D have a better prognosis than women who don’t. A prognosis is how quickly a doctor expects a patient to recover or how long a doctor expects a patient to live.
那些乳腺癌患者的血液中含有较高含量的维生素D，她们的预后比那些没有维生素D的女性更好。预后就是医生预期患者恢复的速度，或者是医生预期患者还能存活多长时间。

Researchers found that these women had less aggressive cancers. They were also 30 percent less likely to die from the cancer or to get it again.
研究人员发现这些女性患有较少的侵袭性癌症。她们死于癌症或再次复发的概率也减少了30％。

Researcher Song Yao led the study for the Roswell Park Cancer Institute.He said the study showed that high Vitamin D levels improved the patients’ prognosis no matter what type or how advanced their cancer was.
研究员宋珧（Song Yao）领导着罗斯韦尔公园癌症研究所（Roswell Park Cancer Institute）的研究。他说，研究表明较高含量的维生素D改善了患者的预后，无论癌症的类型或进展如何。

Besides fighting breast cancer, Vitamin D helps the body in other ways.
除了战胜乳腺癌，维生素D有助于身体的其他方面。

Most importantly, Vitamin D controls how the body absorbs calcium. It also makes sure the body’s immune system works normally.
最重要的是，维生素D控制身体吸收钙的方式。还能确保身体的免疫系统正常工作。

Getting enough Vitamin D is important for normal growth of bones. If you don’t get enough, you are at risk of developing osteoporosis, a disease that makes your bones fragile, brittle, or easy to break.
获得足够的维生素D对于骨骼的正常生长十分重要。如果您获得的维生素D不够充足，那么就有患上骨质疏松症的危险，这种疾病使您的骨骼脆弱，容易破碎。

Several studies show that Vitamin D also strengthens the immune system and helps the body fight disease.
几项研究表明，维生素D也能够加强免疫系统，并有助于身体抵抗疾病。

Vitamin D may help reduce your risk of developing heart disease, according to a 2008 study published in the journal Circulation. And, it may also help protect you against getting the flu.
根据2008年发表在《循环》杂志的一项研究表明，维生素D有助于降低患心脏病的风险。并且，它也有助于保护你免受流感。

Other studies have shown that vitamin D might help people suffering from depression.
其他研究表明，维生素D或许对患有抑郁症的人有所帮助。

But how do we get enough vitamin D?
但是我们如何获得足够的维生素D呢？

Factors in the environment may limit our exposure to sunlight and, therefore, Vitamin D. These factors include pollution, using too much sunscreen, spending too much time inside and living in areas with little sunlight.
环境因素可能会限制我们晒太阳，因此，也会限制维生素D。这些因素包括污染，过多使用防晒霜，呆在室内过久，以及生活在阳光较少的地区。

So, if you can’t get enough sunshine, eat foods that are rich in Vitamin D: egg yolks, cheese and fatty fish such as salmon, sardines, tuna or mackerel.
所以，如果你不能得到足够的阳光，那么就吃富含维生素D的食物，比如蛋黄、奶酪和脂质鱼，如鲑鱼、沙丁鱼、金枪鱼或鲭鱼。

Some foods such as orange juice, yogurt and cereals are fortified with Vitamin D. They are also good sources.
还有一些食物，比如橙汁、酸奶和谷物都含有维生素D。它们也是很好的选择。

How much Vitamin D you need is a debated topic.The best way to know if you need more Vitamin D is to get tested by a doctor.
需要多少维生素D，这是一个备受争议的话题。知道你是否需要更多维生素D的最好方法就是让医生测试。
