eli5 is there actually iron, magnesium, zinc etc. in food

Question

When they say, for example in the cashew nut, that it contains a lot of magnesium and iron. Is there actually tiny bits of metal in it? Do I have to think like atom size? Or am I totally not getting this? Then explain like I’m 3.

You can take brand flakes like Total, put them in a ziplock with water, mush them up, and use a magnet to extract the iron in them.
