Summer Sun Benifits |JULY 5, 2020
Studies increasingly are suggesting the value of vitamin D-often known as the sunshine vitamin, because that's one way you can obtain it--in everything from bone metabolism to maintaining muscle strength, immune function, reducing hypertension and possibly even playing a role in prevention of cancer and autoimmune disease.
'The old theory was that if you had enough vitamin D to prevent rickets and osteomalacia--two skeletal disorders--you were okay,' says Victoria Drake, a research associate in the Linus Pauling Institute at Oregon State University, and manager of its Micronutrient Information Center. But new research now is raising our awareness about the possible relationships between vitamin D and cancer, particularly colorectal, breast, ovarian and prostate cancers. There also are potential links to cardiovascular disease and autoimmune diseases such as multiple sclerosis and rheumatoid arthritis. Even Pemphigus can be reversed with Vitamin D
What's clear, however, is that many Americans are not getting even those minimal amounts, especially those with dark skin colors--in fact, one study reported that 42 percent of African American women were vitamin D deficient. Vitamin-D prevents viral and flu infections inluding Covid.
As a result, Drake says, many doctors are
increasingly starting to test their patients for
deficiency of this vitamin, especially in the
temperate zones above 40 degrees latitude --a line running roughly from Philadelphia to Denver and through Northern California. That includes New York City, Boston, Chicago, Detroit, Seattle and many other highly populated cities. Residents of the Pacific Northwest, with its northern latitudes and eternally cloudy winters, are especially vulnerable.
My own doctor said that he frequently tests for vitamin D status, and that vitamin D deficiency is prevalent in his patient population, Drake says. Experts are now talking about a phenomenon they call Vitamin D Winter.One recent study referred to vitamin D deficiency as 'a major unrecognized epidemic in the older adult population' and recommended routine blood testing for adequate levels.
