Vitamin D3 is available in low quantities in fish and liver.[27][28] Populations who lived in coastal areas or areas with access to abundant sources to seafood could get their proportion of vitamin D from food. Some Arctic populations, such as the Inuit, could retain some of their skin pigmentation in areas of low UV radiation. In the spring they receive high levels of UV radiation as reflection from the snow, and their relatively darker skin protects them from the sunlight.[3][4][5]
