Seafood Affecting Skin Colour?

Seafood is an interesting factor that also surprisingly affects skin colour. Seafood is an excellent source of vitamin D, so people who have diets rich in seafood are high in vitamin D. This is most commonly seen in people who live in coastal areas, where fish is a primary source of food in their diet. A common case for Eskimos, and people who live in the Arctic regions. Since such high amounts of vitamin D are consumed, the skin doesn't need to reduce pigmentation. A pigmentation reduction would be necessary for those who were not eating a shellfish abundant diet. If these people reduce the amount of seafood they are accustomed to eating, they face the risk of vitamin D deficiency which can lead to osteoporosis.
