Iron's Safety: Taking a Closer Look
Iron-fortified foods such as breakfast cereals don't pose a special health risk to most people. That includes the one out of every 10 Americans who has one normal and one altered form of a gene linked to iron overload.Men and women volunteers with that genetic makeup did not absorb significantly more iron from their foods in comparison to volunteers with two normal genes for iron absorption, researchers have found.
Scientists at the ARS Grand Forks (N.D.) Human Nutrition Research Center worked with data from volunteers—100 healthy men and women in this study—and presented their findings in a 2004 issue of the American Journal of Clinical Nutrition.Certain foods are iron-fortified to ensure that we get the recommended daily amount of this essential mineral.
