Extracting iron from enriched cereal with hard drive magnet

Uploader info:

I recently saw a video ( http://www.youtube.com/watch?v=5ahlawrQHeA ) where it was demostrated that
some iron-enriched foods actually contain enough metal to be magnetic. I wanted to see more of this, so I did the
experiment(s) myself and sure enough - even the cereal I had for breakfast was magnetic!

In this video, you'll see floating magnetic Bran Flakes, the free-standing magnetic Bran Flake demonstration, and finally, the actual magnetic iron material extracted from the
cereal and shown under high magnification.

This sort of iron looks similar to the kind of black iron you would collect by passing a strong magnet
through ordinary soil. After a bit of reseach, it turns out that this "reduced iron" will dissolve
in the your stomach's hydrochloric acid (at least to some degree), and can be absorbed for your bodily processes, although probably not as efficiently as the more colloidal iron found naturally in plants/non-processed foods.

Some more interesting reading on this subject:
