Vitamin D is known as the sunshine vitamin, and it has a lot of sunny benefits, but most Americans aren't getting them because they aren't getting enough of it.

维生素D又叫阳光维生素，对人体有益处多多。但大部份美国人却缺乏维生素D，也就得不到相应的好处了。

Between 50 percent and 75 percent of Americans get suboptimal levels of vitamin D, according to a study published in the Archives of Internal Medicine.

根据国际医学档案公布的研究数据，50%~75%的美国人的维生素D水平不达标。

Why People Are Vitamin D Deficient

为何会缺乏维生素D

Nature gave us only one good source of vitamin D, and that is the sun. We are meant to absorb vitamin D from the sun through our skin. When we lived closer to the equator and worked outdoors, we were OK. But that is not the case today. And food is not a good source of vitamin D, not even fortified food.

最天然的获取维生素D的方式只有一个：阳光。通过日晒，我们的皮肤能从阳光中获取维生素D。如果我们生活在赤道地区，并在户外工作，通过阳光获取维生素D就非常简单。但是情况并非如此。而且，食物并不是维生素D的最佳来源，即便是强化食物也是如此。

Five Ways to Get Vitamin D

获得维生素D的五种方法

15 Minutes of Sun 3 Times Per Week

每周三次日晒，每次15分钟

You can get 10-15 minutes of high-noon sun exposure in warmer climates a few times a week. In the South you can do this all year long; but in the North it will work only in the summer months. But this is unrealistic for those who already wear sunscreen all day, or have been warned to stay out of the sun by their doctors.

天气温暖的时候，每周在正午太阳下暴露10至15分钟数次。在南方全年都有条件做到，但在北方只有夏天光照才适合。但对于总是涂抹防晒霜的人，或被医生建议避免阳光直射的人来说，这一方法并不现实。

Fatty Fish and Cod Liver Oil

含脂肪多的鱼类和鱼肝油

If you are one of those people who have been warned to stay out of the sun, another good natural source of vitamin D is fatty fish. In food, vitamin D is naturally found in fatty fish like salmon and in cod liver oil.

如果你就是被禁止接受阳光直射的人，那么。另一种天然获得维生素D的办法就是吃含脂肪多的鱼类。维生素D含量最丰富的食物是脂肪较多的鱼类，比如鲑鱼，以及鱼肝油。
