Most plastic products, from sippy cups to food wraps, can release chemicals that act like the sex hormone estrogen, according to a study in Environmental Health Perspectives.

Many plastic products are now marketed as BPA-free, and manufacturers have begun substituting other chemicals whose effects aren't as well known.
