Infection - sunlight proved to help fight infection
Fighting infections with vitamin D.Two related pathways within the skin and circulating monocytes-macrophages are highlighted. Sunlight converts 7-dehydrocholesterol (7-DHC) in the skin to vitamin D3, which is converted successively to 25-hydroxy-D3 (25-D3) and then to 1,25-dihydroxy-D3 (1,25-D3) within keratinocytes. Sunlight also induces expression of the vitamin D receptor (VDR). 1,25-D3...More
Infertility
Vitamin D and Infertility A new report adds credence to the idea that infertility may be due in great part to vitamin D deficiency. Dr. Anne Clark, who works at the Fertility First clinic in Sydney, Australia, assessed the blood levels of vitamin D among about 800 men who were unable...More
Influenza
On the epidemiology of influenzaThe evidence that vitamin D has profound effects on innate immunity is rapidly growingVirology Journal 2008, 5:29doi:10.1186/1743-422X-5-29AbstractThe epidemiology of influenza swarms with incongruities, incongruities exhaustively detailed by the late British epidemiologist, Edgar Hope-Simpson. He was the first to propose a parsimonious theory explaining why influenza is,...More
Low Vitamin D Link
Low vitamin D levels 'linked to Parkinson's disease'Having low vitamin D levels may increase a person's risk of developing Parkinson's disease later in life, say Finnish researchers.Their study of 3,000 people, published in Archives of Neurology, found people with the lowest levels of the sunshine vitamin had a three-fold higher...More
Lung Cancer Survival and Vitamin D
Improving Lung Cancer SurvivalVitamin D may help people with lung cancer to live longer, according to a study released in 2005. The most common cause of cancer death in American men and women, lung cancer can be challenging to treat effectively. The report found that men with early-stage non-small cell...More
Lung Health
Supporting lung healthPeople with higher levels of vitamin D in the bloodstream demonstrate better lung function than their counterparts with lower vitamin D levels, according to a recent report. Researchers examined 14,000 participants and found that people with higher vitamin D levels could inhale and exhale substantially more air, as...More
MS & Arthritis may be linked to lack of sun
MS and arthritis may be linked to lack of sun, say scientistsVitamin D found to exert an influence over genes associated with certain diseases more common in the northern hemisphereThe Food Standards Agency says a healthy diet plus ‘a little' exposure to sun should give us all the vitamin D...More
Melanoma
MelanomaAn inability to tan is the number one risk factor for melanoma. Those who tan easily or who have darker skin are far less likely to develop the disease. A new theory is that melanoma is actually caused by sunlight (vitamin D) deficiency and that safe sun exposure actually helps...More
