Kitchen store and new pans

After stopping in at one of my favorite hangouts, (kitchen store) yes i am a geek, the owner told me about a report from the late 70's which did not get alot of attention. The coating of non-stick pans and skilets over time leach into your food and can chip and peal off. The effect is shocking. The coating goes to your kidneys and then due to is structure does huge ammounts of dammage. This stunned me. I could be hurting my children every time I cook. With some digging arround in the basement I dug out grandma's cast iron collection. This is a set that no one should be with out. Skilet, duchoven, deep skilet, and griddle. After some complaining from my wife all of our non-stick stuff went out the door and in the trash. What I found out was if you season the cast iron right it creates a natural non stick surfice.
