The Great Debate Over Plastic Water Bottles
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?

"I've carried a water bottle for YEARS - first the toxic Nalgene bottles, then the BPA-lined Sigg bottles, and finally a stainless steel bottle. I replace that bottle when I lose it, which averages 1 - 2 times per year. "
CRAP!! I was just shopping for a SIGG bottle - haven't bought one yet - they're BPA lined? :(
I can't do stainless steel - I'm allergic to metal and sensitive to the taste. I just WON'T drink it from a purely metal container. What to do, what to do? - 3/8/2011 3:32:20 AM
I've been phasing out plastics for a couple of years now. Two years ago, a pre-op blood test showed I had abnormally high levels of estrogen, and not the good kind. I have packed my lunch for ages and I used to haul that lunch around in a plastic container (and then I'd microwave my food in that same container). I now store my food in glass (Weck jars, while pricey, are all glass and natural rubber - no plastic coating whatsoever), transport my lunches in glass, eat off a ceramic plate in the office with real silverware... for me, it's worth the little bit of hassle to know I'm putting my food in something as non-reactive as it gets. - 8/30/2010 5:12:27 PM
The Canadian government made a big deal a few years ago to ban baby bottles that may contain BPA. They didn't ban it for adult use, and even when they banned baby bottles they didn't consider that the lining of formula cans also contains BPA. It was just a big political PR exercise. - 8/3/2010 7:02:38 PM

Besides, eating/drinking from glass just makes me feel decadent (less "trailer-trashy"). Smiles - 2/23/2010 11:53:30 AM

I switched to stainless steel water bottles about 2 1/2 years ago, before the debate over BPA was regular news. I made the switch simply because I was trying to do better things for me (save $$ on water bottles) and the environment (save water bottles from trash and recycling). Even though I reused my water bottles for weeks, even months, the taste of the water (even filtered water) was quickly effected, especially if the bottle became warm or hot at all from sun.
Water from stainless steel tastes better. period.
I bought baby bottles that are BPA free, food containers that are BPA free or glass. I try to heat food up in a regular bowl or plate rather than the container it was refrigerated in. I use only non-toxic, non-chemical cleaners in my house, including dish soap and dishwasher detergent.
If you have a choice to do something that could potentially be better for you, your family and ultimately the environment--why wouldn't you? I think that is the real question.
As to whether or not I trust the FDA, well, many people say I am too young to be cynical, but I have yet to trust our government about or with anything... I am not going to start with their "take" on BPA, especially when LOTS of big chemical companies NEED BPA to be safe. - 2/22/2010 11:37:54 AM
I have been slowly replacing my plastic containers with glass and pyrex. When I store I make sure there is enough room on the top to not touch the plastic lid. I always wash the lids by hand. I am still using some Tupperware because I still need them. Can't afford to switch all at once.
I usually drink my water out of a glass because I'm a SAHM, but will have to find a travel cup that I'm happy with soon. I wish they made insulated stainless bottles. I hate when my water gets heated up. - 8/17/2009 9:20:08 AM
I thinks it's disgraceful that these so-called agencies that are supposed to be safeguarding our health are allowing such bad chemicals to be used in consumer products. Do any of them really care about us? - 8/7/2009 2:36:44 PM
Plus it feels good not to create more plastic waste, even if it's just a small amount. - 8/7/2009 1:24:20 PM
To me, it isn't just about whether or not the FDA and goverernment are lying to us about the possible health risks of BPA, but about protecting the most important natural resource we have... the earth. If it gets too sick to recover...whether or not BPA can cause disease really won't matter much. - 7/1/2009 12:30:25 PM
Even if the plastic is pretty safe, I don't want to add to land fill. - 10/9/2008 12:35:57 PM

As you can see, single-use bottles rarely contain BPA -- it's the heavier plastic reusable bottles that contain it. - 10/6/2008 9:40:21 AM

I know we can't avoid all of the possible dangers in this life, but some changes we make for ourselves can affect the greater good. - 10/5/2008 4:33:20 AM
Though it brings up new possible human health risks, the study, which is being discussed today at a meeting of the Food and Drug Administration's science advisory board, offers no conclusive answers. It does not prove a cause and effect between use of plastic food containers and the development of diabetes or heart disease.
"We don't have a lot of evidence in people about the effects of BPA. This is one of the first studies, and it finds something disturbing. It's suggesting there may be harm in adults, which we didn't really believe based on the animal studies," says David Schardt, a staff scientist with the Center for Science in the Public Interest.
I agree with others who say that, if there is a concern, stop reusing or using those plastics. I also agree that due to modernization and progress we now are exposed to a lot of things that have adverse affects on our bodies. The flip side to that coin is that people are living much longer today due to the advances in modern medicine.
Until there is a definite link between certain health problems and using plastic, I will continue to use my bottled water. I might go back to using glassware for reheating in the microwave. I never cook anything in plastic, but that isn't because I am afraid that it isn't healthy. It's just a matter of convenience for me. - 10/4/2008 4:51:47 PM
I don't distrust FDA. It's just that I am older now and am a cancer survivor. I had so many chemo and radiation treatments that I know my immune system is not the best. So I decided to be cautious about plastics.
Thanks so much for this information! - 10/4/2008 7:35:16 AM

Correlation does not equal causation, as another poster pointed out. Still, many of the ladies and gentlemen on scienceblogs.com don't think the FDA is looking at the right data in regards to BPAs and question the FDA's assertion that BPAs aren't harmful.
Personally, I'm not making any major changes in my life, but I will if more research shows a more direct link between certain diseases and BPAs, but I certainly wouldn't buy baby bottles with BPA in them -- that precaution is pretty much universally agreed upon.
BPA is actually more common in canned foods (from the sealant), so even if you ditch the water bottle, you'd have to eliminate all canned foods from your diet to eliminate any actual risk. - 10/3/2008 9:50:55 AM
