In another link from LinkedIn, we have a story about a study started 12 years ago, in Africa. In the US, iron supplementation is a common part of pregnant women's life; the benefits to the developing child can't be overestimated. In Africa, many children suffer from iron-deficient anemia. It seemed a natural solution to supplement the diet with iron supplements and other vitamins. However, during the study, more children on the supplement died than those not on the supplement, bringing the study to an abrupt and early end. I'll let you read the story for yourself; the reasons for the confusing results still aren't entirely understood, but are being sought out in order to hopefully correct both the nutrient deficient and the fatal result of correcting it in areas where malaria is endemic. I highlight it, however, not only because it's another LinkedIn story, but because it serves as an excellent reminder of the law of unintended consequences: solving one problem may cause another, or several others. While this is a large-scale example of unintended consequences, even in your lab work, you may encounter the same problems. Look for more detail on this idea in future posts.
