The Iron Edge examines educational and health implications of iron metabolism along with providing instructions for remedying common problems with iron absorption leading to enhanced memory, cognition, and expanding learning capacities. The author, also co-author of Dangerous Grains and Cereal Killers, after many years of chronic iron deficiency secondary to celiac disease, writes about his own exploration of iron deficiency and brain function and data subsequently used to write his doctoral dissertation. Many of the same principles can be applied to normalizing status of other minerals including calcium, magnesium, and zinc. The principles outlined can help readers prevent and reverse iron deficiency, often reversing learning difficulties, memory loss, low energy, and a host of other problems. This is a must read for parents, teachers, and caregivers who want their children to achieve to their highest potential.
