Cornbread in the cast iron pan  For menstruating women and most kids, yes. The numbers vary, depending on the study, but somewhere between 20% and 80% of women during the childbearing years are iron deficient. They’re not so deficient that they are anemic, but the symptoms are the same: They’re tired, more susceptible to colds and infections, can’t think clearly, and might even sleep more fitfully. Besides pumping up the iron content of your diet, throw out that expensive cookware and return to Grandma’s cast iron. The iron leaches out of the pot into the food, boosting iron content several fold, especially in acidic foods such as spaghetti sauce and tomato-based soups.  Photo credit: Jen Waller via Compfight
