Staying Out of the Sun Prevents Skin Cancer but Not Osteoporosis

Australians are so obsessed about staying out of the sun to prevent skin cancer that the number of people getting osteoporosis is increasing. This is a sad consequence of a positive behavior change. Osteoporosis would not be a problem if more people took calcium tablets with vitamin D each day. Unfortunately, many would rather spend their money on other things. The disease affects young people as well as the elderly. The Nepean Consensus Statement meeting has been praised for making the disease more widely known. However, money spent on such activities is wasted, considering you can treat yourself without actually being diagnosed with the disease. Developing "fancy" management practises is unnecessary. Giving calcium and vitamin D to the elderly who already suffer with osteoporosis is a waste of time, because once you have the disease it cannot be cured. A person need not adopt a calcium rich diet: calcium and vitamin D in tablet form are easily absorbed by the body. Eve

Reduced Lung Fuction Due to Vitamin D Deficency in Dark Skinned People

No wonder West Indians had a rough time when they moved to the UK in the mid-twentieth century: with the polluted atmosphere common at that time many suffered from a vitamin D deficiency. Their children born in the UK had more problems than their parents because growing up in a sun depleted climatic environment with a dark skin led to long term lung problems. Australian research shows the lack of vitamin D leads to altered lung structure, with the lungs partially shutting down. In adult life people of West Indian heritage have decreased lung function. Mice were tested with some being made deficient in vitamin D while others had an adequate level. Tests with a plethysmograph showed lung obstruction was markedly greater in mice lacking vitamin D. Overall, lung volume was reduced. Lungs were also smaller than average. It was unclear as to whether the problem was basically due to heritage, or mothers being deficient during pregnancy, because test mice had to be bred to have low sun-to-vita
