白领改善健康的简单方法
Top up vitamin D levels

Spending short periods of time in the sunshine is a great way to top up your vitamin D levels, but if it's pouring outside or you truly can't leave your desk, there are other ways, such as eating plenty of oily fish.
晒一小会儿太阳是提高维生素D水平的好办法，但如果外面大雨倾盆或者你实在无法离开办公桌，还有一些其他的方法可以达到这种效果，比如多吃油性鱼类。
"The best way to get vitamin D is from spending lots of time in the sun, but if this is not an option, try taking a supplement," advised nutritionist Cassandra Barns.
营养学家卡桑德拉·巴恩斯建议，获取维生素D的最好办法就是多晒太阳，但如果这不可行，试试服用补充剂吧。
