There are over 80,000 synthetic chemicals in commerce today, including hormone-disrupting phthalates and air pollutants. Smith and Lourie prove how easily our bodies absorb these chemicals from the foods we eat, the air we breathe, and the products we smear on our skin-- day after day. Then they give us the good news about what is in our control and the steps we can take for reducing our toxic burden. The result is nothing short of a prescription for a healthier life.
