Indeed, just use stainless steel pots for your tomato sauce. That said, I throw some acidic stuff in my cast iron and I can't say I can notice the metallic taste. A cast iron pan is not really a replacement for stainless steel (I don't think anyone has anything against those), it's a replacement for non stick pan. Calling it a replacement for non stick pan is actually quite insulting: nothing sears meat like a cast iron pan, we should say that non stick pan are a poor replacement for cast iron pans. The reason I moved to cast iron pan (more than health concerns or caring about the environment) was to cook meat like chefs on youtube do, after years of cooking mediocre dishes on non stick pans. The only major downside is the weight (2kg) and how hot it gets - which makes it hard to use for the miss.
