This is the only pregnancy book that I've found that actually lays out all of the scientific studies regarding safety in pregnancy. I know that I'm not supposed to drink alcohol, eat sushi, etc, but I want to know what the no kidding statistical data say about these things. This book gives you historical data, stats and percentages so that you can make informed decisions for yourself. I still don't do all of the (potentially) risky things that the book says are probably okay, but it's nice to have the peace of mind when I realize halfway through dinner that the waitress brought me a med rare steak instead of med well or that I accidentally drank some egg nog that was spiked instead of regular.
