(Newser) – One aspect of the bisphenol A controversy can be put to rest: drinking from clear plastic bottles does increase the amount of the chemical in the body. The extent of BPA's effects on healthy adults is still not well known, but the FDA says existing exposure levels aren't high enough to harm even infants, reports the Boston Globe.

The Harvard study, the first to show a causal link between drinking cold drinks from plastic bottles and elevated BPA levels, found that concentrations of the chemical in subjects' urine went up 69%. "If you heat those bottles, as is the case with baby bottles, we would expect the levels to be considerably higher," one of the report's authors says.
