Plastic water bottles and their potential health risks are a hot topic in the news these days. How do you know if you’re at risk? Is it really something to be concerned about? A recent study in the Journal of the American Medical Association found that adults with the highest levels of BPA in their urine were more than twice as likely to report having diabetes or heart disease — compared with adults with the lowest levels of the chemical in their urine. BPA (bisphenol A) is a chemical that’s been found to leach from water bottles and plastic cans. It’s also found in baby bottles, tableware and food storage containers. Although there is no conclusive evidence that links BPA to health problems, studies have produced conflicting results. This new study does not prove a cause and effect between use of plastic food containers and the development of diabetes or heart disease, even though it does bring up the possibility of new health risks. The study’s authors say more follow-up research is necessary to see if the same results can be duplicated. To minimize exposure to BPA, avoid microwaving plastic containers or washing them in the dishwasher with harsh detergents. High heat and harsh cleansers can deteriorate the plastic and release BPA. Many people also avoid water bottles with the number 7 on the bottom, since those are known to contain small amounts of the chemical. The FDA discussed the findings last week at a meeting of their science advisory board. Their conclusion is that the margin of safety for this chemical is adequate, and it’s safe to continue its use. Do you trust the FDA’s assessment? Have you discontinued the use of any products that you know contain BPA? What are your feelings on this topic? |
