100% of Your USRDA of Iron?!

We did an experiment last week that was really fun:
- We bought a box of Total and crushed 1 c until it was a really fine powder.
- We put the powder in a ziploc bag and added water.
- Then we used a magnet to slowly draw around the cereal mush -- after a few seconds we could see speckles of iron that had separated from the cereal.

So how does your cereal have 100% of your USRDA of Iron? By adding tiny iron shavings... LOL

That is very funny!
You are better of grinding an apple and waiting until it turns brown and eating it. As far as I remember, only Fe+3 is readily utilized by our bodies.
I wonder what you can find in all the vitamins and mineral supplements you see in the drug stores.
