They just released a new study saying that nalgene may be more harmful than the cheap plastic water bottles a lot of people are replacing

We wrote about this a couple of months ago, but it appears there’s nothing to worry about. It’s only a problem if you heat the bottle at 250 degrees for 20 minutes.
Here’s the link, followed by an excerpt:
http://www.t-nation.com/findArticle.do?article=06-121-diet
T: You’ve mentioned xenoestrogens in pesticides a lot. But I know one of the popular topics is xenoestrogens and plastics. They always seem to be mentioned in the same sentence together. What’s the connection there?
JW: Several studies have shown that xenoestrogens can leach from plastic polycarbonates. There is one particular study that I just looked at.
The researchers were actually looking at culture medias with different chemicals to see which types of chemicals were estrogenic. They found one solution that was incredibly estrogenic, but it wasn’t related to the chemicals that they added. Instead, it was the bottle that they heated the solution in.
Basically, they were using Nalgene polycarbonate bottles. Most of us are familiar with Nalgene bottles. I use them too. They are very convenient for drinking water or what not.
But when those bottles were heated, in this case 250-degrees Fahrenheit for 30 minutes (this is just beyond the point of boiling for a significant time period), they found rather potent levels of the xenoestrogen, BPA.
They then did a control for the study where they just used distilled water in the Nalgene bottles, heated them up and found the same effect. This is pretty scary news.
There have been dozens of studies showing different levels of xenoestrogens coming from plastics, specifically soft plastics. You want to avoid heating up plastics containing food, water, or drinks.
T: That must not have made Nalgene happy.
JW: True, but we can’t really pick on Nalgene. The researchers were using Nalgene bottles because they are one of the best brands for strength and reliability. Any plastic bottles would have produced the same results. And let’s face it, not many of us are boiling liquid in our Nalgenes for 30 minutes.
For Christmas my GF got us all-stainless steel coffie travel mugs for this very reason.
Bonus: the coffie actually tasts better coming out of hot steel than hot plastic, and it stays hotter longer!

always on top of things eh lol
thanks for that, I missed that article
the good thing that came out of it all is finding out about the sigg bottles

Another alternative that could be used if you simply don’t like the taste of plastic is glass.
Personally, I drink out of Voss bottles…can be found at various grocery stores in the south and at World Market. For 3 bucks, it’s a hell of a deal…unless you’re clumsy.
However, some gyms frown on their use, since they’re trying to sell you their pretty plastic bottles with the cool monogram on the front…‘and if you act today, not only will you receive this bottle, I’ll sell you my mother’s “services” for one night, for the discount price of only 39.99!’
Or you could use an empty gatorade bottle, and just not heat it, right?
