And again, in moderation (like anything else), peanut oil is "good for cooking".
Then again, one slice of frozen pizza will kill you dead.
5 or so years ago (and certainly further back), most on these forums would have had heart attacks if you suggested they consume coconut oil (OMGz saturated fatzzz).
There are 'healthier oil' like virgin OO, but when you heat them up beyond their smoke point, they break down and become worse than higher smoke point oils. No one knows if OP's o3/o6 is out of whack or not.
No one bothered to ask what OP's goals or concerns were, or what his 'health history' was. Question was simply "is it good to cook with". Yes. It is.
Better alternatives? Sure. He knows it and implied that they are expensive (possibly prohibitively so). So given that he's got peanut oil out the wazoo and that's what he can afford, the answer should be "There are alternatives X, Y, and Z, but if that's what you can afford, use it in moderation (like everything else)."
So many binary thinkers here.
