如何正確攝取維他命D呢? 聽聽美國皮膚科醫學會的建議與實證

• 來自太陽和助曬機的紫外線ＵＶ會導致皮膚癌，AAD不建議從陽光或助曬機獲得維生素D。這當中包括了「黑色素癌」，一種可能致命的皮膚癌。​

​

• 為預防紫外線誘發的皮膚癌，AAD建議民眾做好防曬工作﹕找尋騎樓與樹蔭等遮蔽陽光的路線、衣服覆蓋皮膚、未覆蓋的皮膚則塗上SPF大於30的廣效型防水防曬霜。

​

• AAD建議從健康飲食中獲取維生素D，如富含維生素D的食物、食品和飲料、及 #維生素D補充劑。

• 雖然維生素D對健康的骨骼很重要，也有些研究發現維生素D可降低癌症發病率、癌症死亡、提高癌症存活率。但是其他研究尚未能夠確切證實維生素Ｄ與癌症的關聯性。

​
美國國家醫學科學院（NAM）根據目前鈣和維生素D在骨骼健康的科學實證，建議每日維生素D的膳食攝取量（RDA）：國際單位（IU）
​

1. 400 IU　適用於 0-1 歲的嬰兒/兒童
2. 600 IU　適用於1-70歲的兒童，青少年和成人
3. 800 IU　適用於 71 歲以上的成年人　
4. 維生素D攝入量不應超過每天4000 IU

（每個人從太陽接受的維生素D量並不一樣，而紫外線又有導致皮膚癌的風險，因此NAM的RDA是基於接受最少或沒有陽光照射的人的建議。）
