A Vitamin D Deficiency
缺少维生素D
Living with the short days in the North Pole, not to mention working the night shift in December, can cause a serious deficiency of Vitamin D, the sunshine vitamin, which has been linked to several health problems. Santa should aim to take a supplement that provides 1,000 IU of the nutrient. In addition, he should consider increasing his consumption of Vitamin D-rich foods, such as salmon or fortified milk.
圣诞老人住在日短夜长的北极，在12月还要加夜班，这就会使他严重缺乏维生素D。维生素D可以通过日晒获得，如果缺少维D，就会引起多种健康问题。因此，圣诞老人每天要多补充1000个国际单位的维生素D，还要多吃富含维D的食物，比如鲑鱼和强化奶。
