Fellow Rachel Morello-Frosch believes, despite the uncertainties, doctors and other clinicians can offer women very useful advice. For example, diets rich in organic foods reduce exposures to pesticides, as measured by urinary levels of their metabolites. And people can choose not to buy body lotions known to contain phthalates or furniture with foam cushions steeped in flame-retardants. Indeed, advising patients on the best ways to reduce potentially toxic chemical exposures is an essential component of public health prevention.
