Will induction cooking burn away the iron minerals (iron ions) present in the food being cooked?

Question

For example imagine the situation when the induction waves reaching the food being cooked, howver I am well aware that induction waves dont harm the non-ferromagnetic content, however some green leefy vegetables have got iron mineral (an essential food supplement) which is unfortunately ferro-magnetic. So my concern wont this induction cooking burn the minute iron mineral in the food being cooked.

Answer 1

It is impossible to burn away any metal minerals in any food. Food chemists actually burn food all of the way till its just a small pile of ash. The only thing left in this pile of ash are the minerals that were in the food. So it does not matter what type of heating is used, the minerals will not be destroyed in any manor.

All you can do to minerals at very high heat is oxidize them. But at this point your body can still use those minerals. It may not be as efficient for your body, but they are still available.

Answer 2

I don't think iron compounds are ferromagnetic.
Even if they were, The iron won't be destroyed
