Natural Vitamin D Levels 46 ng/ml: Study
A first-of-its-kind study of vitamin D levels among those whose outdoor lifestyles give us the best clues of what is natural for humans supports the contention that regular tanners have natural vitamin D levels and non-tanners are falling far short.
Published in the British Journal of Nutrition by Dr. Martine F. Luxwolda and a group of colleagues from The Netherlands, the study looked at Vitamin D blood levels in those who live natural outdoor lifestyles.
“People with traditional lifestyles, living in the cradle of mankind, have a mean circulating 25(OH)D concentration of 115 nmol/l (46 ng/ml),” the group wrote. “Evolutionary medicine tells us that our genes have been selected in an environment in which we successfully exploited hunting and gathering strategies for survival and procreation. Since the agricultural (about 10,000 years ago) and industrial (100–200 years ago) revolutions, we have, however, drastically changed our conditions of existence and continue to do so with still increasing pace. These changes cause a conflict with our slowly adapting genome that basically still resides in the Paleolithic era.”
In other words, our body’s genes haven’t caught up to the recent phenomena of working indoors behind a desk.
