Yet, this does not mean we should try to give a totally iron free diet. Actually, this would be very difficult and prevent the use of DSM in formulas. UN specifications for indusrtrial F100 preparation accept that and the request usually made to F100 producers is NOT to add iron. Please note that levels found by Ariane are much less than the dose presumably given as supplement in the Nigeria study. Other remark iron in milk is also known to be poorly absorbed, and in any case much less than iron given between meals.
Iron tablets are more toxic than iron in food.
Even micro-encapsulaton of iron dramatically reduces toxicity in acute animal models. See Boccio et al. In conclusion, the pendulum should not go too far, and until there is more evidence, be happy provided iron is not added to the F100 formula. I hope this helps.
