Yes, according to experts, chemicals in plastics and other everyday items do make us fat. Recently, we reported on BPA's link to obesity, but BPA isn't the only synthetic chemical thought to possibly increase fat storage. PCBs, phthalates, PBDEs, and PFOA—all common household chemicals in everything from carpet to toothbrushes—are also suspect. To find out more about where these lurk, check out Children's Health Magazine's breakdown (via this Grist roundup of commentary and evidence on this issue). Have you done anything to avoid these chemicals? Where do you concentrate your efforts? Food, cleaning products, household items? As a parent, I easily become overwhelmed and guilt-ridden at the fact that I haven't replaced ALL of the plastic cups, toys, and bedding in our home.
