Red Wine Decreases Prostate Cancer Risk
A study of 753 newly diagnosed prostate cancer cases in men aged 40 to 64 years of age were compared to 703 cancer free subjects matched by age. Each additional glass of red wine consumed per week showed a statistically significant 6% drop in the risk of developing prostate cancer. This effect was not found for beer or liquor. The study is published in the January 1st, 2005 issue of the International Journal of Cancer.

Wine is rich in Resveratrol and Grape Seed OPCs, ingredients lacking in beer and liquor. These wine ingredients have tremendous health benefits.
Low-Level Lead Exposure Tied to Mental decline with Age
Exposure to low levels of lead in the environment over a life-time seems to contribute
to mental deficit as people age. Lead is a toxic heavy metal that is found in air, soil,
and water. Lead can accumulate in the body. Exposure to even low levels of lead in children
can cause brain damage and both behavioral and learning problems. In adults it can lower
your I.Q., damage the kidneys, brain, and nerves, and contribute to high blood pressure.
In this study researchers wanted to evaluate the impact low levels of lead accumulation has on the general population - something that we know little about. Researchers from Harvard in conjunction with other institutions found that the higher the level of lead in older men's bones at the start of the study, the greater their mental decline with time. The source of lead was from environmental exposure. The study is published in the December 2004 issue of the American Journal of Epidemiology.
NSAID Anti-Inflammatory Drugs May Not Prevent Dementia
Researchers from the department of Gerontology and Geriatrics at Leiden University Medical Center in the Netherlands analyzed 25 studies to assess the ability of NSAID drugs such as naproxen and ibuprofen to [prevent senile dementia. The researchers believe that the NSAID drugs lacked the ability to prevent dementia in their final analysis. They believe that any ability that may have shown up in the studies was due to various forms of bias: recall bias, prescription bias, and publication bias. The study is published in the January 15th 2005 issue of the American Journal of Epidemiology.
