For those that like to worry about such things, stainless pans can leach out chromium and nickel, neither one health-ensuring additives. I guess to be ultra-safe, one could just stop cooking......but then you have all those nasty pathogens to worry about.
"In these days of indigestion it is oftentimes a question
As to what to eat and what to leave alone.
Every microbe and bacillus has a different way to kill us
And in time they all will claim us for their own.
There are germs of every kind in every food that you can find
In the market or upon the bill of fare.
Drinking water's just as risky as the so-called "deadly" whiskey
And it's often a mistake to breathe the air.
