Johns Hopkins has recently sent this out in its newsletters.
This information is being circulated at Walter Reed Army Medical Center. 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 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, Corning Ware 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 Saran wrap 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.
