Doctors Warn About Dangers of Genetically Modified Food


(NaturalNews) The American Academy of Environmental Medicine has warned that the public should avoid genetically modified (GM) foods, stating, "There is more than a casual association between GM foods and adverse health effects. There is causation."

A large number of studies and incidents have implicated GM foods in a wide variety of health problems, including accelerated aging, immune dysfunction, insulin disorders, organ damage and reproductive disruption.

For example, female rats fed a diet of GM soy experienced a drastically higher infant death rate, and their surviving infants were smaller and less fertile than the offspring of rats fed on a non-GM soy diet. Male rats fed the GM soy had their testicles change from pink to blue, and the GM soy was also observed to damage the DNA of sperm and embryos. Fertility problems such as abortion, infertility, premature delivery, prolapsed uteri, infant death, and even delivery of unformed infants (bags of water) have been observed in farm animals fed GM cottonseed and corn.

Animals consuming crops that have been genetically modified to produce the pesticide Bt (approved for human consumption in the United States) have died by the thousands, while animals grazing on a non-GM version of the same crops remained unharmed. Upon autopsies, researchers have found black patches in the animals' livers and intestines, internal bleeding and other signs of Bt poisoning. Farm workers in India have begun developing allergic reactions upon handling Bt corn, similar to the effects experienced by people exposed to Bt spraying.

In addition to these risks, GM soy and corn contain significantly higher concentrations of allergens than unmodified varieties. Evidence also suggests that the genetic abnormalities of GM foods may transfer to bacteria in the human gut, thereby exposing people to their detrimental effects long after a food has been consumed.

Yet in spite of all this evidence and the prevalence of GM crops in the U.S. food supply not a single clinical trial of any GM crop has ever been published.

"The experiments simply haven't been done and we now have become the guinea pigs," said Canadian geneticist David Suzuki. "Anyone that says, 'Oh, we know that this is perfectly safe,' I say is either unbelievably stupid or deliberately lying."

Herbicide Chemical in Drinking Water Could Pose Much Greater Danger to Health Than Previously Thought





(NaturalNews) Contamination of drinking water by a common herbicide poses a greater health threat than previously believed, according to a report issued by the nonprofit environmental organization Natural Resources Defense Council (NRDC).

The Environmental Protection Agency (EPA) monitors average yearly levels of the popular herbicide atrazine in drinking water supplies, based on four tests per year. But the NRDC notes that levels of the toxin in drinking water regularly spike after heavy rains or during the spring when it is being widely applied, and that the four yearly testings may miss these events. The organization's researchers found several such spikes in its own testing of water supplies in towns in agricultural regions of the South and Midwest.

"Our biggest concern is early-life-stage development," said Jennifer Sass of the NRDC. "If there's a disruption during that time, it becomes hard-wired into the system. These endocrine disrupters act in the body at extremely low levels. These spikes matter."

Because atrazine is compatible with no-till farming, it is popular among farmers seeking to acquire a "green" label by reducing their carbon footprint. It is known to disrupt the hormonal system, and may cause cancers and menstrual problems in adults. It is considered especially dangerous to the developing reproductive systems of fetuses and children. The chemical has been shown to kill aquatic microorganisms and suppress the immune systems of larger animals, and it can cause limb or reproductive deformities in amphibians at levels as low as 0.1 parts per billion.

The EPA has set a threshold of 3 billion parts per billion for permissible atrazine levels, which the NRDC says would be too high even without periodic spikes. The NRDC analysis of 139 different municipal water systems found that 54 of them had a one-time spike higher than 3 parts per billion at some point in 2003 or 2004.

Home or municipal carbon filters can remove atrazine from water, but many municipal treatment plants do not use such procedures.
