The reviews on Amazon of this book make it sound like a must-have, a convenient pocket-size guide to what chemicals are risky. I learned about it while browsing books on Amazon after following a link from a website called www.GreenHomeGuide.com which is a site I recommend. I've known too many people who died from cancer - non-smokers who lived generally healthy lives. One grew up on a farm and the pesticides around him I believe had something to do with it. The other, I find no explanation for. I think that there must be a correlation between all the chemicals used so reguarly in our lives now and the huge increase in cancer rates in the last century. In our capitalistic society, however, food-making companies have no incentive to care about the health impacts of what they put in their products, except to the extent that consumers educate themselves and use their "power of the purse" to demand what is most healthy. So I believe this book will be a good tool for consumers to check labels and only buy what is truly healthy.
