Higher blood levels of Selenium in combination with Vitamin E or in conjunction with a Multiple Vitamin greatly reduces the risk of developing prostate cancer
In this nested-case controlled study (a top of the line study) in a large population of men it was found that nutrition has a strong protective effect with cancer. In men who had a good intake of both Vitamin E and Selenium there was a strong 42% drop in risk of developing prostate cancer; these men had higher blood levels of selenium and were taking in more vitamin E than normal. If the man used a Multiple-vitamins and had a higher blood level of Selenium his drop in the risk of developing prostate cancer was 40%. In smokers with a high serum level of Selenium the decrease in risk was 35%. The study is published in the January 2007 issue of the American Journal of Clinical Nutrition.
Vitamin D helps prevent macular degeneration while Fish Oils help prevent the most severe form
Age related macular degeneration occurs in the central retina resulting in significantly reduced vision or even blindness. In about 10% of cases the wet form occurs; a big risk for going blind. In these more advanced patients little blood vessels form inappropriately in the retina; they burst and lead to scarring of the retina. In this study that included 7752 people it was found that having the highest levels of Vitamin D in the blood vs. the lowest decreased the risk of developing macular degeneration by 36%. However, for the advanced wet form that leads to blindness it was found that DHA at higher levels was associated with a 46% reduction. The overall fish oil related reduction in risk was calculated at a 59% reduction. The study is published in the May 2007 issue of the journal Archives of Ophthalmology.
