[GreenYes] Fwd: Re: Plastics & food

 >> Subject: Warning about ALL plastics & food
 >> Apparently, it's not just microwave ovens and plastic wrap that

 >> cooking pans) and ethylhexyl adepate (DEHA) -- found in all
 >> plastics.
 >> Some cancer patients using alternative methods of treatment
 >> are asked to discard all plastic food containers with a warning
 >> that ANY food stored in or cooked in plastic, be it oven wear,
 >> microwave or storage of liquids in plastic (even in the
 >> refrigerator) can be contaminated through leaching of this
 >> chemical.  Only dry foods are safe to store in plastic.
 >> Since most canned foods are lined with plastic, they are
 >> also warned against (this includes sodas and canned juices, since
 >> all aluminum cans are apparently lined in plastic).
 >> Safe to use: Cast Iron, Stainless Steel, and glass.  Pyrex
 >> makes storage containers with glass bottoms and plastic tops,
 >> which work fine as long as the food does not touch the lids.
