"In a study of Japanese schoolchildren, vitamin D supplements taken during the winter and early spring helped prevent seasonal flu and asthma attacks. The idea for the study, study chief Dr. Mitsuyoshi Urashima, told Reuters Health, came from an earlier study looking at whether vitamin D could help prevent the bone-thinning disease osteoporosis. The researchers in that study noticed that people taking vitamin D were three times less likely to report cold and flu symptoms." - Reuters Health (Mar 19, 2010)The vitamin dujour is vitamin D. Whether its treating asthma, cancer, the flu, schizophrenia or brittle bones in the elderly the focus seems to be on the hormone vitamin and its curative effects in the news and in research. The hormone status hasn't been settled. There is still some disagreement with the Standing Committee on the Scientific Evaluation of Dietary Reference Intakes conclusion. (PDF)
Unless you're sick enough seems to be enough. Actually enough might be too much if you're looking for preventive measures.
“Historically the amount of sunshine which people have typically been getting was adequate, certainly up until the mid twentieth century when we started to do silly things like sunbathing and wearing bikinis, and before that time people were already sourcing enough vitamin D from everyday foods like fish, mushrooms and eggs.” - ScienceAlert (April 24, 2009)Whether accidental or not a discovery that makes us better even when science is looking in the wrong direction or for something completely different is still a good thing. Usually the result is hair growth or something involving the male organ. Like going to see if you've got email and discovering its about that drug or something to enhance your maleness. These kind of scientific discoveries are so much better.
