Some food products are fortified with essential minerals like zinc, calcium, and iodine. Usually, these minerals are added in the form of their compounds. For example, zinc is added in a food product as zinc sulfate.
However, food technologists found a way to safely add a mineral even if it is in the elemental form. Quite an irony to the usual fortification methods, isn’t it? Even the element’s name suggest so.
This video shows that the iron present in a commercial food product is in its elemental form.
Keep in mind though, that the iron added in food products underwent a process that makes it safe to ingest. This iron is made to be food grade.
Those found in iron nails or eating utensils should NOT be ingested — these are non-food grade!
