皮肤白皙的挪威人 淺膚色 是指一種顏色 較白的膚色 ，擁有淺膚色的人黑色素 較少，而且一般生活在紫外线 較弱的地區，他們一般會被稱作白人 。 [ 1] [ 2] [ 3] 欧洲 和东北亚 的原住民的膚色較淺。 [ 4] [ 5] [ 6] [ 7] [ 3] [ 8] 纬度 地区，這些地方的太阳光 强度较低。 [ 9]
1960年代，生物化学家W. Farnsworth Loomis發現，生活在高緯度的淺膚色人群能吸收更多的维生素D 。浅色（菲茨派屈克度量 II 型）皮肤的人产生前维生素D3 的速度比深色皮肤（ V 型 ）的人要快5-10 倍。而一定量的维生素D有助于人體吸收更多的钙 。 [ 10] [ 11] [ 12] [ 13] [ 14] [ 15] [ 16] 驯鹿 的肉、内脏和脂肪 都含有大量维生素D。 [ 17]
黑色素 可以防止葉酸耗盡出現葉酸缺乏症 以及DNA受损 。[ 3] [ 18] [ 19] [ 20] 太阳光 強度較高的赤道 附近時，他們體內叶酸 耗竭的风险會增加。如果叶酸耗尽的話，他们會面临更高的DNA损伤 、先天性障碍 和罹患多种癌症 （尤其是皮膚癌 的风险。 [ 3] 雀斑 。[ 21] [ 3] I 型和II 型 ）在黑色素细胞中产生的黑色素非常少，并且在紫外线辐射的幾乎很難產生黑色素，[ 22] 结缔组织 和脱氧核糖核酸 會被破壞，过早衰老 皮膚癌 。[ 23] [ 24] III-IV型 膚色的人在受到紫外線輻射後就能产生黑色素。[ 25] [ 26]
隨著新航路開闢 後各大洲人员流动日益頻繁，当今世界各地都有浅肤色人群。 [ 3] [ 27]
