What’s hid­ing in your bot­tle?

WE ALL drink from plas­tic wa­ter bot­tles, and some of us carry them around 24-7 and con­stantly sip away.

But is that drink bot­tle you so dearly cling to on an al­most daily ba­sis safe for you? Should you be ditch­ing the plas­tic fan­tas­tic and stick­ing glass bot­tles in your bidon holder?

Let’s dive into the re­search, see what’s lurk­ing and make a solid rec­om­men­da­tion for all you health-con­scious en­durance ath­letes out there.

Bisphe­nol-A, more com­monly known as BPA, can be found lurk­ing in cer­tain plas­tic prod­ucts, lin­ing canned food prod­ucts and other poly­car­bon­ate plas­tic prod­ucts found through­out our daily lives.

More per­ti­nent to you, the en­durance ath­lete, is the fact that the wa­ter bot­tles we use on a daily ba­sis have been made with this in the past and may or may not con­tain the nasty lit­tle chem­i­cal now.

A large body of ev­i­dence out­lines the fact that BPA is a com­mon en­docrine (con­trols hor­mones) dis­rupter and has been linked to an ar­ray of health im­pli­ca­tions (mainly in an­i­mal mod­els) – al­though let’s be hon­est here, what hasn’t been linked to cancer or other dis­eases th­ese days?

How­ever, as al­ways with sci­ence, it is ever evolv­ing and despite the US Food and Drug Ad­min­is­tra­tion (FDA) say­ing cur­rent tox­i­c­ity lev­els are okay, there is the other side of the coin that sug­gests we re­ally still don’t know just how bad this stuff is.

There’s al­ways that lit­tle tagline at the end of a sci­en­tific study that says “more re­search needed to make a strong con­clu­sion”. When does it end?

What we do know how­ever, and let’s keep it sim­ple (’cause that’s how I roll), is this:

The use of plas­tic bot­tles con­tain­ing BPA on a reg­u­lar “nor­mal rou­tine” ba­sis has been shown to in­crease lev­els of BPA in the body – not re­ally a good sign.

We know that plas­tics ex­posed to heat, whether from hot wa­ter in­side the bot­tle or from ex­ter­nal sources (like the sun on a bot­tle in your car per­haps) greatly in­creases BPA leach­ing out into your wa­ter.

Ex­pos­ing plas­tic bot­tles to de­ter­gents can also in­crease the amount of BPA re­leased from the plas­tic.

There is a plethora of choice when it comes to bot­tles th­ese days … so be safe and opt for BPA-free where you can.

Does this mean avoid­ing plas­tic bot­tles like the plague? Not nec­es­sar­ily, if you go by the FDA rec­om­men­da­tions that cur­rent tox­i­c­ity lev­els are “safe” – are we even meant to have th­ese in our bod­ies? Prob­a­bly not, right!

But if you have the choice, it’s prob­a­bly safer to avoid it (BPA). Choose bot­tles made with the 1, 2, 4 or 5 re­cy­cling codes; avoid 3, 6 and most plas­tics with the 7 la­bel.

Re­mem­ber too, the sci­ence is young, ever-evolv­ing and BPA is one in­gre­di­ent in a long list of chem­i­cals used to make plas­tic prod­ucts.

The scep­tic in me says, if you can, choose an­other op­tion; the sci­en­tist in me is still on the fence. I think for the most part though, peo­ple are pretty aware of this stuff th­ese days and, as such, com­pa­nies mak­ing our bot­tles are go­ing down the BPA-free path. It doesn’t hurt to check though.

Final words of ad­vice… choose bot­tles with the re­cy­cling codes 1, 2, 4 or 5, keep them cool and out of the sun where pos­si­ble, don’t use the dish­washer and rinse with cold wa­ter. Avoid heat­ing your plas­tic bot­tles for any rea­son, fill­ing with hot liq­uids, leav­ing your bot­tles in the car and us­ing de­ter­gents to clean them out.

Look for bot­tles with 1, 2, 4 or 5 re­cy­cling codes.
