Alien54's Journal: Vitamin D casts cancer prevention in new light

For decades, researchers have puzzled over why rich northern countries have cancer rates many times higher than those in developing countries -- and many have laid the blame on dangerous pollutants spewed out by industry. But research into vitamin D is suggesting both a plausible answer to this medical puzzle and a heretical notion: that cancers and other disorders in rich countries aren't caused mainly by pollutants but by a vitamin deficiency known to be less acute or even non-existent in poor nations. What's more, researchers are linking low vitamin D status to a host of other serious ailments, including multiple sclerosis, juvenile diabetes, influenza, osteoporosis and bone fractures among the elderly.
