Chemical Used in Non-Stick Cookware Continues to Prove Its Toxicity ...
There seems to be more evidence mounting in the ongoing Perflurooctanoic Acid (PFOA) debate. PFOA is used in the production of Teflon and other non-stick surfaces and is found in the packaging of candy bars, microwave popcorn, fast food packaging like french fry and pizza boxes, bakery items, drinks, paper plates, and a host of "stain resistant" products such as carpets. Other well-known brand names containing PFOA include Stainmaster, Scotchgard, SilverStone, Fluron, Supra, Excalibur, Greblon, Xylon, Duracote, Resistal, Autograph and T-Fal. Although the DuPont Corporation has stated that PFOA is only used in the manufacturing process and should not be found in the final products, it must be noted that the chemical is found in the bloodstream of 95% of American men, women, and children. It seems that no one is quite certain how the chemical residue has made it into the bloodstream of such a large number of people if it is not located in the final product. Research has shown that PFOA was still present in the blood for approximately four years after exposure and levels were only reduced by half. It has been implicated by some research to cause increased instances of cancer in the pancreas, liver, testicles, and mammary glands. Also increased were instances of miscarriage, weight loss, thyroid problems, weaker immune systems, and low organ weights.

Diabetes And Alzheimer's Disease Linked By Salk Institute Study...Diabetic individuals have a significantly higher risk of developing Alzheimer's disease but the molecular connection between the two remains unexplained. Now, researchers at the Salk Institute for Biological Studies identified the probable molecular basis for the diabetes - Alzheimer's interaction.
In a study published in the current online issue of Neurobiology of Aging, investigators led by David R. Schubert, Ph.D., professor in the Cellular Neurobiology Laboratory, report that the blood vessels in the brain of young diabetic mice are damaged by the interaction of elevated blood glucose levels characteristic of diabetes and low levels of beta amyloid, a peptide that clumps to form the senile plaques that riddle the brains of Alzheimer's patients.

High-fructose corn syrup, high fat diet cause severe liver damage...A diet high in fat and in high fructose corn syrup may cause severe liver problems in people with a sedentary lifestyle, according to a study conducted by researchers from Saint Louis University and presented this year at the Digestive Diseases Week meeting in Washington, D.C.
Researchers fed mice a diet that was 40 percent fat and high in high fructose corn syrup for 16 weeks. In contrast to other studies, where mice have been fed a regulated amount, the animals in the study were allowed to eat as much as they wanted. They were kept sedentary and prevented from exercising.
"We wanted to mirror the kind of diet many Americans subsist on, so the high fat content is about the same you'd find in a typical McDonald's meal, and the high fructose corn syrup translates to about eight cans of soda a day in a human diet, which is not far off with what some people consume," said Brent Tetri, M.D., an associate professor of internal medicine at Saint Louis University Liver Center.

Cup Of Coffee A Day Could Help Protect Against Alzheimer's Disease, Study Suggests...
A daily dose of caffeine blocks the disruptive effects of high cholesterol that scientists have linked to Alzheimer's disease. A study in the open access publication, Journal of Neuroinflammation revealed that caffeine equivalent to just one cup of coffee a day could protect the blood-brain barrier (BBB) from damage that occurred with a high-fat diet. The BBB protects the central nervous system from the rest of the body's circulation, providing the brain with its own regulated microenvironment. Previous studies have shown that high levels of cholesterol break down the BBB which can then no longer protect the central nervous system from the damage caused by blood borne contamination. BBB leakage occurs in a variety of neurological disorders such as Alzheimer's disease.

Popular Energy Drinks Cause Tooth Erosion, Study Shows...
For more than 10 years, energy drinks in the United States have been on the rise, promising consumers more "oomph" in their day. In fact, it is estimated that the energy drink market will hit $10 billion by 2010. While that may be great news for energy drink companies, it could mean a different story for the oral health of consumers who sometimes daily rely on these drinks for that extra boost. Previous scientific research findings have helped to warn consumers that the pH (potential of hydrogen) levels in beverages such as soda could lead to tooth erosion, the breakdown of tooth structure caused by the effect of acid on the teeth that leads to decay. The studies revealed that, whether diet or regular, ice tea or root beer, the acidity level in popular beverages that consumers drink every day contributes to the erosion of enamel.

Skip the Bacon and Stay Thin to Avoid Cancer, Says World Cancer Research Fund ...
The World Cancer Research Fund has issued detailed recommendations on how to decrease cancer risk through lifestyle changes, including staying thin and avoiding bacon or ham. A panel of nine teams of scientists reviewed more than 7,000 studies on the relationship between lifestyle choices and cancer. "If people are interested in reducing their cancer risk, then following the recommendations is the way to do it," Professor Martin Wiseman said. "Cancer is not a fate, it is a matter of risk, and you can adjust those risks by how you behave. It is very important that people feel that they are in control of what they do."

Broccoli and Tomatoes Fight Prostate Cancer...
Yesterday I was working in London, and as I waited for the bus I saw a sign that said “One man in Britain dies from Prostate Cancer every hour.” As my dad, grandfather and great grandfather have all had Prostate cancer, it is of particular interest to me. am pleased to know that there is a very simple recipe for preventing this form of cancer... eating broccoli and tomatoes together on a daily basis. Both of these have cancer-fighting properties individually, but their super foods super power for fighting prostate cancer in men dramatically increases when consumed together.
“When tomatoes and broccoli are eaten together, we see an additive effect. We think it’s because different bioactive compounds in each food work on different anti-cancer pathways,” said University of Illinois food science and human nutrition professor John Erdman who led the study.
Researchers implanted prostate cells into laboratory rats. Some of the rats were fed a diet of 10 percent tomato powder and 10 percent broccoli powder. These rats did better than the other rats that were fed just tomato powder, just broccoli powder, or just lycopene, which is the red pigment in tomatoes believed to have potent health benefits. Another set of rats was fed finasteride, a prostate drug, whereas a last set of rats were castrated.
