The : The johns hopkins medical alert letter states that the quotes from johns hopkins in popular email letters are falsely attributed. According to rolf halden, phd, pe, assistant professor in the department of environmental health sciences and the center for water and health at the johns hopkins bloomberg school of public health, we should be more concerned with the quality of the water we drink than the containers water comes from. However, some water bottles contain phthalates, and these can leach into the water at a rate related to how hot the water gets. There is some current understanding that the chemicals released into water by phthalates can act like the hormone estrogen in the body, causing a variety of impacts. The best thing seems to not heat up foods/drinks in plastic containers unless they were designed for this. It may in future become clear that we should limit our exposure to water from plastic bottles; at this time most people are limiting exposure of babies and young children more than adults.
