I loved the original article, and (spoiler) it pretty much turned out to be what was posited but they're not sure why the iron levels were low. In the way these things usually go, they decided destroying the withheld US stocks was cheaper than shipping it elsewhere for sale or (illegally?) feeding the needy.<p>I'm wondering though, is fortification/enrichment in staples widespread? The US seems to do it a lot, but I checked in Australia and I can find only 2 cases of mandatory fortification[0] - Vitamin D for oil spreads (e.g. margarine) and vitamin B1 and folic acid for bread flour, and iodised salt in the bread. I suppose you can also include fluoridated tap water as fortification. I don't have either of those foods that often so hopefully I'm getting these nutrients elsewhere.<p>0: <a href="https://www.foodstandards.gov.au/consumer/nutrition/vitaminadded/Pages/default.aspx" rel="nofollow">https://www.foodstandards.gov.au/consumer/nutrition/vitamina...</a>
