This was a hard book to put down. Scientifically oriented, yet written in simple language for all of us "non-scientists" to understand, it's reader friendly. This book applies to our everyday life. We already know many things cause cancer and other diseases, but to finally have a book that tells us what THOSE things are, empowers us to make a change. We've heard our water might be contaminated, well Dr. Berkson will tell you why and what exactly is in it that makes it bad. We've heard to be cautious of dry-cleaning gas off, and she'll cover that, she talks about heating our food in plastic trays and plastic wrap in the microwave, dangers in baby toys, baby foods, our soda cans and cans in general. She talks from a hormone point of view: in parts per billion (which is like a pinch of salt in 10 tons of potatos, her words, not mine) when referring to the sensitivity of these hormones. She warns us of estrogenic invaders, androgenic invaders, hormone blockers and such, that are in our environment in the form of air, food, cleaning products, water pollution and how these interfere with our bodies. The best part: she tells us how to reduce our exposure, what we can do about it by just being aware.
