It's the Vitamin D stoopid! A science teacher explains: https://www.facebook.com/grace.pokela.1/posts/10100443953660160
There is even an exception to this rule, and it’s an exception that PROVES the rule.
There is one group only of people who have lived with very little sunlight for a very long time, but who still have brown skin. This group is the American Inuit (Eskimos.) They live in an area where the sun shines not at all for a large portion of the year! According to our vitamin D rule, they should be among the palest of the pale of all of the Earth’s people. And yet, they are brown. Why?
They are brown for one very, very simple reason. Inuit eat a lot of seal and whale meat. And can you guess what vitamin seal and whale meat contains tons of?
That’s right- vitamin D!!!
Inuit have brown skin for the simple reason that they’ve spent thousands of years getting their vitamin D from their diets, and NOT from the sun.
I am so, so sick of living in a world wherein people whose recent ancestors needed to efficiently conserve folic acid are treated differently than people whose recent ancestors needed to efficiently make vitamin D. It is. So. Stupid.
