Choosing Safe Food Containers - NYTimes.com Re "How Chemicals Change Us," by Nicholas D. Kristof (column, May 3): Concerns about the use of bisphenol-A, commonly known as BPA, have been raised by scientists and regulators for many years. Many polycarbonate plastics used in food containers undergo processes that result in the release of BPA into food, beverages, the environment and our bodies. While the Food and Drug Administration did not outright ban the use of BPA in March, it did announce its continued concern and commitment to further study BPA's effects. The choice of your container may be as important as the choice of the food itself. Many consumers prefer glass packaging because it preserves the taste of the food or beverage it contains while reducing toxic health concerns. This is perhaps best evidenced by the fact that glass has been designated by the F.D.A. as "generally recognized as safe," or GRAS status, the agency's highest standard.
