The Importance of the "Sunshine Vitamin" During the Dark Winter Months
“陽光維生素”，曬太陽就可以補充！但要注意這幾點
The connection between sunlight and bone health was made over 200 years ago when a Polish doctor treated inner city children with rickets (or soft bones) by taking them to the countryside for the summer months. In fact, vitamin D promotes heart, metabolic, and immune system health in addition to supporting bone health.
200多年前，當一位波蘭醫(yī)生帶著患有佝僂病（或軟骨頭）的城市兒童去鄉(xiāng)下避暑時，發(fā)現(xiàn)了陽光與骨骼健康之間的聯(lián)系。事實上，維生素D除了有益骨骼健康外，還對心臟、新陳代謝和免疫系統(tǒng)健康有益。
Vitamin D is absorbed into our bloodstream and converted to the active form (a secosteroidal hormone) and a storage form (25-hydroxyvitamin D) – it functions more like a hormone than a vitamin. So, it is no surprise that having sufficient levels of vitamin D is so important for a broad array of health effects.
維生素D被血液吸收，并轉(zhuǎn)化為活性形式（一種開環(huán)甾體激素）和儲存形式（25-羥基維生素D）——其功能更像是一種激素而不是維生素。因此，充足的維生素D對健康有著重要影響。
Potential benefits associated with vitamin D include:
維生素D的潛在健康益處包括：
Aids in calcium absorption for maintaining strong bones and teeth
促進鈣吸收，保持骨骼和牙齒強健
Helps support healthy heart and immune function
有益心臟健康和增強免疫功能
Facilitates healthy cell development
促進健康的細胞發(fā)育
"Vitamin D is produced when sunlight touches our skin, and very few foods in nature contain vitamin D, with fortified foods – primarily cow's milk – being responsible for most of the vitamin D in the American diet," said Jamie McManus, Shaklee's Chair of Medical Affairs. "As daylight savings time ends, we have less opportunity to absorb vitamin D through sunlight. Therefore, people should supplement their vitamin D intake, especially during winter."
美國營養(yǎng)品公司嘉康利醫(yī)學事務(wù)主席杰米·麥克馬納斯稱：“當陽光照射皮膚時，人體就會產(chǎn)生維生素D，自然界中含有維生素D的食物較少，而牛奶是美國人飲食中維生素D的主要來源。隨著夏令時間結(jié)束，通過陽光吸收維生素D的機會減少。因此，人們應該補充維生素D攝入量，尤其是在冬季。”
