Ultraviolet light from the sun converts this into Vitamin D<sub>3<\/sub>, also known as cholecalciferol.<\/p>\n<p>Cholecalciferol is brought by the blood to the liver, where is it converted into the cleverly named 25-hydroxyvitamin D 3 [25-(OH)D 3 ] by a liver enzyme. This is brought to the kidneys by the bloodstream, where it is converted into calcitriol by the kidney mitochondia.<\/p>\n<p>Vitamin D is most famous for its action in the intestines, where it is essential for the absorption of calcium, making the mineral available to form bones. The lack of Vitamin D causes the bone disease rickets.<\/p>\n<p>But what has caught my attention is the lesser-known effects of Vitamin D on cancers, such as <a href=\"http:\/\/www.annalsnyas.org\/cgi\/content\/abstract\/889\/1\/107\" target=\"x\">colorectal cancer<\/a>, <a href=\"http:\/\/cancerres.aacrjournals.org\/cgi\/content\/abstract\/56\/18\/4108\" target=\"x\">prostate cancer<\/a>, <a href=\"http:\/\/www.ncbi.nlm.nih.gov\/entrez\/query.fcgi?cmd=Retrieve&amp;db=PubMed&amp;list_uids=2563099&amp;dopt=Citation\" target=\"x\">breast cancer<\/a>, <a href=\"http:\/\/ije.oxfordjournals.org\/cgi\/content\/abstract\/23\/6\/1133\" target=\"x\">ovarian cancer<\/a>, <a href=\"http:\/\/www.jncicancerspectrum.oxfordjournals.org\/cgi\/content\/full\/jnci%3b97\/3\/161?rss=1\" target=\"x\">non-melanoma skin cancer<\/a>, and <a href=\"http:\/\/www.ingentaconnect.com\/search\/expand?pub=infobike:\/\/ap\/jr\/1996\/00000061\/00000001\/art00092&amp;unc=\" target=\"x\">malignant melanoma<\/a>. These last two in interesting, since the same ultraviolet light from the sun that creates Vitamin D also causes skin cancer. But occupations that give workers more sunlight seem to protect agains all of these cancers, especially breast and colon cancers.<\/p>\n<p>So, people who are slathering on sunblock and avoiding sun exposure to prevent skin cancer are also eliminating a source of a substance known to help fight cancer. The good news is that various forms of Vitamin D are available in <a href=\"http:\/\/ods.od.nih.gov\/factsheets\/vitamind.asp\" target=\"x\">dairy products and vitamin supplements<\/a>.<\/p>\n<p>And guess what the two most common forms of cancer are in the United States?  <a href=\"http:\/\/chetday.com\/skincancersun.htm\" target=\"x\">Skin cancer<\/a>, and <a href=\"http:\/\/www.ncbi.nlm.nih.gov\/entrez\/query.fcgi?db=PubMed&amp;cmd=Retrieve&amp;list_uids=91053053&amp;dopt=Citation\" target=\"x\">prostate cancer<\/a>.<\/p>\n<p>Drink your milk folks.
