A Truth Bomb on Skin Color and Vitamin D.

Skin needs to be struck by sunlight to synthesize vitamin D, which is an immunoregulating hormone. Dark skin contains melanin, an effective natural sunscreen that reduces vitamin D synthesis.

The correlation of different skin colors all over the world (see attached illustration) is perfect with UVA/UVB radiation intensities. Neither cancer nor God or diversity had anything to do with the evolutionary pressure on the skin pigments. It's simply a health feature!

This explains why light skin was favored in dimmer regions such as Scandinavia as it boosted vitamin D synthesis.

Western lifestyles and religious practices, however, can have a serious impact on health. Office jobs or wearing burkhas reduces the exposure to sunlight and lead to serious vitamin D deficiencies.

But Dr. Simon, but why aren't Inuit pale skinned? Well, because their diet mainly comprises vitamin D–rich foods, such as oily fish.

How about African immigrants in Europe? Well, they will face serious health issues if they don't supplement with vitamin D.

How about Europeans in tropical areas? They should supplement with folate (vitamin B9) or eat lots of liver and eggs as intense sunlight can destroy folate in the blood of pale-skinned people.

Best,
Dr. Simon
