I saw someone do a demonstration once, they took a box of "iron-fortified" breakfast cereal, dumped it into a bowl, then ran a magnet through it. The magnet picked up some of the dust from the bottom of the bowl, that dust being the tiny iron particles that were added to the cereal to "fortify" it.
I put them in quotes as the word has no objective meaning as applied to a breakfast cereal, it's simply a marketing term. I did not intend to imply that ingested iron particles are not a valid source of iron for human biology.
put the ''words'' in quotes because in context it's definitely ''absurd bullshit'' and this is how i know that key on my keyboard doesn't work i have to use a different key so thanks
How is it "absurd bullshit"? Do you think it's somehow a different element? At worst, it's as bullshit as any other vitamin supplement, in that it's technically helpful, but just far more than your body can make use of.
Tiny amounts of iron distributed throughout a piece of cereal don’t have enough of a magnetic charge to lift the weight of a piece of cereal. Pieces of cereal dust with higher concentrations of iron very much could. Those results aren’t especially surprising
