You just wrote "inherent", and then you gave a reason that's not inherent to the process of deep-frying. If the use of poor quality oils, and their repeated use are problems, then let's write those into the fda rulebook (and international equivalents), but let's not just say that "deep-frying is bad for you", and condemn the whole enterprise of industrial food processing along with it.
There is a lot of "assuming the worst" going on in this thread and surrounding the topic of "processed foods" in general.
My concern is that turning our backs on industrial food processing is a luxury that many of us simply can't afford, either financially, or in terms of the practicalities of making our lives work.
There may be a lot of things that frequently happen in the processing of foods that lead to bad health outcomes, and the consumption of a diet rich in processed foods may strongly correlate with bad health outcomes, but saying "processed foods are bad for you" is doing a lousy job of identifying in a causative sense what exactly it is that's bad for you, and it's also a "luxury belief" in the sense that Rob Henderson has been talking about [1].
