The irony in your opening reply will not be lost on a lot of people. It’s really the arrogance of science and those whose unquestioning acceptance of its "truths" that's at the heart of our current environmental crisis. Your physics 101 course is appreciated and thank you for taking the time to patronise me in detail. It does, however, neatly sidestep the issues and these, to my simple mind, are that an induction hob, like a micro wave, like wi-fi, like mobile phones etc. etc. have the potential to increase levels of harmful radiation which, in isolation, may be tolerable but combined and added to natural background radiation present a threat to your wellbeing that's avoided at best but should be minimised at the very least.
Getting back to the original topic of this thread which was induction hobs, like micro wave ovens, there’s a school of thought that argues they’re unhealthy because they alter the molecular structure of the food. In the following extract is the core of the dilemma in my opinion.
“Although you may have heard that microwaves kill nutrition, that doesn’t seem to be true. Microwave ovens usually don’t destroy nutrients in food. And in some cases, preparing food in a microwave might actually promote nutrient retention. Nutrients are leached from food during any form of cooking, especially when the food is cooked for a long period of time with high amounts of water. So, for example, boiling carrots might strip nutrients much more drastically than microwaving them, because the carrots’ nutrients might get washed away with the boiling water. However, since we haven’t discovered all the compounds that make up food, we’ll likely never know all of the outcomes that microwaving has on nutrients.”
Why is that extract significant/important? It is because it concludes with a statement admitting to the limits of our knowledge. We use, on a daily basis, many thing that have consequences that most are largely unaware of. Let me give one example, a plastic kettle. Plastic kettles are thought to leach endocrine disrupting chemicals into the water which are harmful. We’ve probably been using plastic kettles for 50 years or so but these issues are only coming to the fore now.
If you look at the instruction manuals for induction hobs they advise that you do not get closer than 30cm to the plate when switched and you use a saucepan that at least covers if not overlaps the rings. You could reasonable argue that nobody would want to stand within 30cm of an induction hob, or any type of hob for that matter, while its on. I don’t, however, recall ever seeing instructions for a gas or ceramic hob that specifically asks you not to stand within 30cm.
