Plastic Bottled Water DIOXIN Danger
LET EVERYONE WHO HAS A WIFE/GIRLFRIEND/ DAUGHTER KNOW PLEASE!
Bottled water in your car is very dangerous! On the Ellen show, Sheryl Crow said that this is what caused her breast cancer. It has been identified as the most common cause of the high levels of dioxin in breast cancer tissue..
Sheryl Crow’s oncologist told her: women should not drink bottled water that has been left in a car. The heat reacts with the chemicals in the plastic of the bottle which releases dioxin into the water. Dioxin is a toxin increasingly found in breast cancer tissue. So please be careful and do not drink bottled water that has been left in a car.
Pass this on to all the women in your life. This information is the kind we need to know that just might save us! Use a stainless steel canteen or a glass bottle instead of plastic!
This information is also being circulated at Walter Reed Army Medical Center ... No plastic containers in microwaves. No plastic water bottles in freezers. No plastic wrap in microwaves.
Dioxin chemical causes cancer, especially breast cancer. Dioxins are highly poisonous to cells in our bodies. Don’t freeze plastic bottles with water in them as this releases dioxins from the plastic. Recently the Wellness Program Manager at Castle Hospital, was on a TV program to explain this health hazard.
He talked about dioxins and how bad they are for us. He said that we should not be heating food in the microwave using plastic containers..... This especially applies to foods that contain fat.
He said that the combination of fat, high heat and plastic releases dioxin into the food.
Instead, he recommends using glass, such as Pyrex or ceramic containers for heating food... You get the same result, but without the dioxin.. So, such things as TV dinners, instant soups, etc., should be removed from their containers and heated in something else.
Paper isn’t bad but you don’t know what is in the paper. It’s safer to use tempered glass, such as Pyrex, etc.
He reminded us that a while ago some of the fast food restaurants moved away from the styrene foam containers to paper. The dioxin problem is one of the reasons....
Also, he pointed out that plastic wrap, such as Cling film, is just as dangerous when placed over foods to be cooked in the microwave. As the food is nuked, the high heat causes poisonous toxins to actually melt out of the plastic wrap and drip into the food. Cover food with a paper towel instead.
This is an article that should be share to anyone important in your life!

Subj: Drinking Bottled Water Kept in Car
...a friend whose mother recently got diagnosed with breast cancer. The doctor told her women should not drink bottled water that has been left in a car. The doctor said that the heat and the plastic of the bottle have certain chemicals that can lead to breast cancer. So please be careful and do not drink that water bottle that has been left in a car and pass this on to all the women in your life.
This information is the kind we need to know and be aware and just might save us!!!!
*The heats causes toxins from the plastic to leak into the water and they have found these toxins in breast tissue. Use a stainless steel canteen or a glass bottle when you can*!
Analysis: False as written, though research into potential health hazards associated with disposable water bottles is ongoing (see updates below).
Newer variants of this warning reiterate the previously circulated claim that microwaving food in plastic containers and/or plastic wrap releases dioxin into the food. Those allegations are discussed here.
Plastic bottles of the type used for commercially marketed drinking water in the U.S. are regulated by the FDA as "food contact substances" and held to the same safety standards as food additives. This means, among other things, that the FDA reviews test data on the safety of the plastics used in water bottles — including the potential for hazardous chemicals leaching or "migrating" from the plastic into the water — and has established that they pose no significant risk to human health. The water itself is also tested and required to meet basic quality standards similar to those set by the Environmental Protection Agency for public drinking water.
Please note that the plastic used in the manufacture of pre-packaged, disposable water bottles is different from those believed to pose a human health threat in other applications, such as baby bottles, plastic children's toys, and reusable sports water bottles. Disposable water bottles do not contain bisphenol A (BPA), for example, about which safety concerns have been raised.
That's not to say that bottled water is absolutely, one hundred percent free of all contaminants, or that chemical leaching never takes place. Studies done on water bottled in FDA-approved polyethylene terephthalate (PET), for example, did find trace amounts of potentially hazardous substances believed to have migrated from the plastic. The important point to take away, however, is that these amounts were minuscule and well within the human safety limits set by FDA and EPA regulators.
According to Dr. Rolf Halden of the Johns Hopkins Bloomberg School of Public Health, consumers face a much greater risk from potential exposure to microbial contaminants in bottled water — germs, to you and me — than from chemical ones. For that reason, most experts suggest not refilling or reusing empty bottles.
It should also be noted that the plastics used in the manufacturer of reusable water bottles vary in composition and quality and may be more susceptible to chemical leaching.
Regarding Sheryl Crow: Some versions of this warning contain the additional claim that musician Sheryl Crow announced during a pre-2008 appearance on the Ellen Degeneres TV show that she got breast cancer as a result of drinking bottled water. While it's true that Crow has discussed her bout with cancer on Degeneres' show more than once and reportedly cautioned viewers against drinking water from heated plastic bottles during one of those appearances, I've found no evidence confirming that she explicitly blamed her own cancer on water bottles. Citing advice from her own nutritionist, Crow did issue a warning against drinking water from heated bottles in a Sep. 2006 statement on her website, but, again, did not claim it was the cause of her own illness.
Update (2009): A new European study raises concerns about the safety of disposable water bottles, which have heretofore (see discussion below) been regarded as safe by the FDA and other government health agencies. Researchers in Germany found evidence of a man-made estrogen-like compound leaching into water packaged in polyethylene terephthalate (PET) bottles.
This type of substance, known as an "endocrine disruptor," has the potential to interfere with estrogen and other reproductive hormones in the human body.
Please note that the authors of the study say more research is required to determine whether, or to what degree, this poses an actual health risk to humans.
