People who tuck into fortified breakfast cereals may actually be causing themselves more harm than good, according to a study by government researchers published in the June edition of the Journal of the American College of Nutrition 2001 (pp. 247-254). Many of the enriched products actually contain more of the nutrients than it states on the labels and studies have shown that getting too much of nutrients such as iron and folate can be harmful. The problem is exacerbated by the fact that most consumers eat more than the recommended portion size.
