There is a very good recent Smithsonian documentary called "Skin Deep" . There is a lot in the documentary about vitamin needs along with the evolution of skin color.

Rickets over the history of the disorder was mentioned several times. Cod liver oil use in the early days.

A very good documentary, it mentions how solar radiation has increased in some parts of the world. Sunshine actually penetrates below the skin and can cause some vitamin deficiencies in the persons blood.
