Consider going light on makeup? Causation has not been shown, but a strong correlative link has been found between diabetes and level of exposure to the phthalates that seep from synthetic household items, Scientific American reports:
Phthalates make plastics such as polyvinyl chloride (PVC) more flexible, and they are added to some cosmetics, perfumes and other personal care products to stabilize colors and fragrances. A wide variety of household goods rely on phthalates, including vinyl flooring, adhesives and shower curtains. More than 75 percent of Americans have phthalates in their urine.
Until now, most phthalate research has focused on reproductive consequences because these compounds seem to disrupt male hormones. Boys exposed to phthalates in the womb had signs of feminized genitalia, which may lead to fertility problems. Researchers also have found neurological effects, including reduced IQs and attention problems in boys.
The new study examined diabetes and phthalate concentrations in 2,350 women who participated in a national survey by the Centers for Disease Control and Prevention from 2001 through 2008. Phthalates as much as doubled the rate of diabetes in women with the highest exposures. Other recent studies also have found similar links between phthalates and metabolic disorders.
