The Journal of Clinical Endocrinology and Metabolism has just recently published a study in their March issue regarding the now epidemic level of worldwide vitamin D deficiency. This new research has found that 59% of the worlds population is deficient in vitamin D, and almost 25% of those studied are extremely low on the vital mineral. While certainly staggering, these numbers gain even more weight when combined with another study from the University of Copenhagen and the Department of International Health, Immunology, and Microbiology. Their studies have determined that vitamin D is linked directly to the bodys immune function by actually arming it.
T cells are white blood cells, or lymphocytes that play a large role in immunity. This research has shown that without vitamin D, they often lay dormant and provide little protection against viruses. When optimal levels of vitamin D are present, these cells are much more active and seek out these foreign bodies. With such a large part of the population affected by this deficiency its entirely possible to say that the H1N1 flu epidemic could have been avoided by supplementing vitamin D rather than vaccines that caused a plethora of other problems once administered, especially when taking into consideration that nearly all who died from H1N1 flu were chronically deficient in vitamin D.
This new research may not seem like a real breakthrough on its own, but again when combined with other information it gathers steam. The fact that nearly all patients suffering from kidney failure, diabetes, cancer, osteoporosis, and multiple sclerosis are dangerously low in vitamin D says that the deficiency could single handedly be the determining factor in so many diseases.
You should already be getting plenty of vitamin C for immune health, so pairing this with more vitamin D could help activate the immune response youve been fortifying already. The best source for vitamin D is of course direct sun exposure, just be sure not to shower right away as it can take a few hours for your skin to properly absorb and process it. The best food sources are fresh fish like salmon, mackerel, and tuna, fortified dairy products like milk, and cheese, and eggs. There are numerous supplements on the market to help as well, but be sure to check the labels because some of them like cod liver oil remove the vitamin D.
