How Sunlight Can Save Your Life ~ Part 2
Experts hotly debate which diseases may truly be caused by vitamin D deficiency. Nevertheless the extent of the evidence and its consistency makes a powerful case for D-deficiency being an important cause of over a dozen chronic diseases and almost as many cancers. Other important factors such as obesity, lack of exercise, or a diet containing too many calories, are also known to increase the risk of many of these diseases. But both obesity and lack of exercise are linked with D-deficiency and so the evidence is confused. Vitamin D, is stored in fat and becomes 'lost' in obese people, while people who take exercise often spend more time outdoors in the sun. Nervous system diseases Last year Professor John McGrath and others at the University of Queensland found that pregnant rats deprived of vitamin D give birth to baby rats with serious brain abnormalities. This work will eventually be seen to be as important as the discovery that folic acid deficiency during pregnancy causes severe spinal deformities (spina bifida) in offspring, or that thalidomide given to pregnant animals causes abnormalities of the limbs. The importance of their article published in Neuroscience (volume 118, pp641-653) has not yet been appreciated but it provides a means of understanding several neurological diseases which have puzzled doctors for more than a century. Multiple sclerosis (MS), Schizophrenia, and Parkinson's disease - people with these diseases are more likely to have winter or spring birthdays. MS and Parkinson's diseases are more common in northern countries or states of America. People with MS have worse symptoms in winter and brain scans show an increase in damage to the brain of MS people in winter. Supplements of vitamin D given to babies may prevent MS and schizophrenia. A very severe form of Parkinson's disease occurs in people with dark skin living in the UK. Continued at: How Sunlight Can Save Your Life - Part 2 Diseases Caused By Vitamin D Deficiency
