How the Sun is absolutely essential to your health Fundamentals of Philosophy Wysong Optimal Health (http://www.wysong.net/optimal_health_page1.shtml) is the fact that we are intimately linked to our genetic heritage. We are what we dictate genetics, not what we impose upon ourselves by modern circumstances we artificially create. This understanding is a master key to health, a heuristic basis for making decisions about diet and lifestyle.
Now, what does this philosophy say about the sun? Dermatologists tell you to hide from it and modern life leads us to believe we can do it just fine by living in caves - offices, homes and cars. But our genetic roots tell us that we should be naked and in a climate where we can be. It is our origins - and what was the norm of 99.9 +% of our history. Should we believe dermatologists and modern lifestyles or our genes and history? The answer is obvious, but few live by its wisdom.
This discussion of vitamin D provide evidence incredible and surprising Wysong philosophy and give you a fundamental element for the health of your success.
The sunshine vitamin
Vitamin D (actually a hormone) is produced in the skin by the action of ultraviolet rays from the sun striking a molecule precholesterol (7-dehydrocholesterol). This converted cholesterol molecule (provitamin D) is also modified (hydroxylated) in the liver and kidneys of the creation of assets 1.25 dihydroxycholecalciferol molecule (1,25 dihydroxy vitamin D3 = calcitriol). The wavelength of UV-B produces vitamin D against the sun (282 nm) is not significantly penetrate the glass. Thus, few windows, when we're inside we can about vitamin D is not generated. Clothing of course further seals our fate as sunscreen SPF above 8 (production of vitamin D reduced by 95%). Living in the northern half of the country (even above 30 degrees latitude, Florida) also condemns people enough sun for nearly nine months of the year. If you are dark skin, you will need as much as ten times the amount of sun as a light-skinned person to produce adequate levels of vitamin D. It is natural enough When skinned people live in latitudes requiring clothes, dark skinned people are really fish out of water there and suffer serious consequences as a result.
Food sources of vitamin include cod liver oil, sardines, salmon, tuna, mackerel, liver, egg yolk, butter, dark green vegetables, algae, fungi, phytoplankton and fortified milk. (Source of Vitamin D plant is the D2 form known as ergocalciferol] ercalciol [and is not as active as the animal sources.) But overall, the food sources provide inadequate levels unless they are eaten raw (the triene structure in vitamin D is degraded by acid and isomerization catalyzed by light) and in sufficient quantities - most of us do not. Our wholesale body hair (forcing us to wear clothes made of natural and living in the vicinity artificially heated) and the fact that there is no negative feedback to stop the production of vitamin D in the skin, strongly argues that we are to be under the sun, does not depend on food scientists to enrich the milk.
Older decreased ability to synthesize vitamin D in the skin, have poorer digestive efficiency and decreased liver and kidney function to convert vitamin D into active forms. There is a reason the elderly to the south and feel better. They might not know exactly why others do not want to shovel snow, but Sol does OLE. In addition, people with malabsorption problems, Crohn's disease, cystic fibrosis of the pancreas, liver and kidney disease or failure, or who have been part of the digestive system were removed with an increased risk of vitamin D . Vitamin D is fat soluble and requires precholesterol and thus "low fat" diets and "low cholesterol" diets put LDCs.
