The N.D.D. Book: How Nutrition Deficit Disorder Affects Your Child's Learning, Behavior, and Health, and What You Can Do About It--Without Drugs by Dr. Sears

It was published in 2009. He isn't totally against meds but focuses on other options first and then talks about how he introduces meds as a next step after other things have been looked at. He is a big advocate of omega-3 but makes other suggestions too. It's a quick, easy read.
