No plastic containers in microwave.
No water bottles in freezer.
No plastic wrap in microwave.
Johns Hopkins has recently sent this out in its newsletters. This information is being circulated at Walter Reed Army Medical Center as well.
- Dioxin chemicals causes cancer, especially breast cancer.
- Dioxins are highly poisonous to the cells of our bodies. Don't freeze your plastic bottles with water in them as this releases dioxins from the plastic.
Recently, Dr Edward Fujimoto, 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 our 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 plastics releases dioxin into the food and ultimately into the cells of the body.
Instead, he recommends using glass, such as Corning Ware, Pyrex or ceramic containers for heating food. You get the same results, only without the dioxin. So such things as TV dinners, instant ramen and soups, etc., should be removed from the container and heated in something else. Paper isn't bad but you don 't know what is in the paper. It's just safer to use tempered glass, Corning Ware, etc.
He reminded us that a while ago some of the fast food restaurants moved away from the foam containers to paper. The dioxin problem is one of the reasons.
Also, he pointed out that plastic wrap, such as Saran, 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.
It’s not clear why so many people are uneasy about microwave ovens. “Maybe it’s because there’s no obvious reason why the food cooks,” offers physicist Louis Bloomfield of the
University of Virginia in Charlottesville, who answers questions about microwaves at howthingswork.virginia.edu.
There's plenty of debate concerning this issue, eg, Microwave ovens: A recipe for cancer. and Microwave myths: fact vs fiction.
And concerning plastic wrap:
E-mails widely circulating around the Internet warn that plastic wraps release the carcinogen dioxin when microwaved. “It’s a chemical impossibility because the precursors for dioxin are not in the plastic wrap,” says George Sadler, a professor of food packaging at the National Center for Food Safety and Technology in Summit, Illinois. The center is a consortium
of scientists from academia, the Food and Drug Administration, and the food industry.
“We are not aware of any plastics that yield dioxin as a breakdown product, absolutely none,” adds Kristina Paquette of the FDA’s Office of Food Additive Safety in College Park, Maryland.
My microwave gets little use and I've never used a microwave cookbook though I have a few of them. I tried to make a cake once and it came out a flat, pale, sad-looking lead-weight. I do, however, use it for re-heating and defrosting food. After reading the above links, I'm not going to lose sleep over it.
