Causes of diabetes | 11 Surprising Diabetes Triggers. Fluoride Action Network. As of September 2016, a total of 57 studies have investigated the relationship between fluoride and human intelligence, and over 40 studies have investigated the relationship fluoride and learning/memory in animals. Of these investigations, 50 of the 57 human studies have found that elevated fluoride exposure is associated with reduced IQ, while 45 animal studies have found that fluoride exposure impairs the learning and/or memory capacity of animals. The human studies, which are based on IQ examinations of over 12,000 children, provide compelling evidence that fluoride exposure during the early years of life can damage a child’s developing brain. After reviewing 27 of the human IQ studies, a team of Harvard scientists concluded that fluoride’s effect on the young brain should now be a “high research priority.” (Choi, et al 2012).

Symptoms of Fluoride Poisoning. Parabens: Chemical found in everyday items ¿needs more investigation¿ after scientists discover it in tumours of ALL breast cancer patients. Parabens are a chemical compound found in everyday toiletry products'The fact that parabens were present in so many of the breast tissue samples does justify further investigation,’ say study leaders By Claire Bates Updated: 15:09 GMT, 12 January 2012 Underarm risk? No link has been proven between deodorants and breast cancer A chemical widely used as a preservative in cosmetics, food products and pharmaceuticals has been found in tissue samples from 40 women with breast cancer. A number of studies since 1998 have raised concerns about the potential role of these parabens in breast cancer as they possess oestrogenic properties. Oestrogen is known to play a central role in the development, growth and progression of breast cancer. Parabens are a chemical compound found in everyday toiletry products including moisturisers, make-up, shaving foam, tanning lotions and toothpaste.
They are also found in numerous brands of underarm deodorant. These ingredients must be printed on the label. BPA's Obesity And Diabetes Link Strengthened By New Study. The modern lifestyle of super-sized french fries and couch potatoes often takes the blame for the rising rates of obesity and diabetes in the U.S. -- perhaps rightly so. But growing evidence suggests another factor in the dual epidemics: modern chemicals. Exposure to even minuscule amounts of synthesized substances -- used in everything from pesticides to water bottles -- can scramble hormone signals, scientists say. This interference can trick fat cells into taking in more fat or mislead the pancreas into secreting excess insulin, a hormone that regulates the breakdown of fat and carbohydrates.
Among the most ubiquitous and scrutinized of these so-called endocrine disruptors is bisphenol A, better known as BPA. The chemical is a common ingredient in plastics and food-can linings. "When you eat something with BPA, it's like telling your organs that you are eating more than you are really eating," says Angel Nadal, a BPA expert at the Miguel Hernandez University in Spain. New Autism Study Implicates Environmental Factors. The researchers did not say which environmental influences might be at work. But other experts said the new study, released online on Monday, marked an important shift in thinking about the causes of autism, which is now thought to affect at least 1 percent of the population in the developed world.
“This is a very significant study because it confirms that genetic factors are involved in the cause of the disorder,” said Dr. Peter Szatmari, a leading autism researcher who is the head of child and behavioral neuroscience at McMaster University in Ontario. “But it shifts the focus to the possibility that environmental factors could also be really important.”
As recently as a few decades ago, thought autism was caused by a lack of maternal warmth. And while that notion has been discarded in favor of genetic explanations, there has been growing acceptance that genes do not tell the whole story, in part because autism rates appear to have increased far faster than our genes can evolve. Dr. Study finds link between autism and obesity during pregnancy. Pregnant women might now have one more good reason to watch their diet and exercise: A new study links autism and developmental delays in young children to metabolic conditions, like obesity and diabetes, in their mothers. The findings, published in Monday's edition of the journal Pediatrics, found that women who had diabetes or hypertension or were obese were 1.61 times as likely as healthy women to have children with autism spectrum disorders. They also were 2.35 times as likely to have children with developmental delays.
Child development experts said the findings were interesting but that it would be premature to suggest that the results could help explain the dramatic rise in diagnosed cases of autism over the last decade. Last month, the Centers for Disease Control and Prevention reported that the autism rate among 8-year-olds in the U.S. had risen to 1 in 88, from 1 in 110 a few years earlier. Copper identified as culprit in Alzheimer's disease.
Copper appears to be one of the main environmental factors that trigger the onset and enhance the progression of Alzheimer's disease by preventing the clearance and accelerating the accumulation of toxic proteins in the brain. That is the conclusion of a study appearing today in the journal Proceedings of the National Academy of Sciences. "It is clear that, over time, copper's cumulative effect is to impair the systems by which amyloid beta is removed from the brain," said Rashid Deane, Ph.D., a research professor in the University of Rochester Medical Center (URMC) Department of Neurosurgery, member of the Center for Translational Neuromedicine, and lead author of the study. "This impairment is one of the key factors that cause the protein to accumulate in the brain and form the plaques that are the hallmark of Alzheimer's disease.
" Copper's presence in the food supply is ubiquitous. The research team – "dosed" normal mice with copper over a three month period.
