The Skinny on Plastics

3 January 2014

BPA BlogHe had his first birthday and then Christmas. He’s been eating more solid food, learning to drink from a cup, and I’m already trying to decide which toys to donate because his collection doesn’t fit in his room.

And almost all of it is plastic.

Bowls and cups are plastic. Toys (which, of course, get chewed on and carried around in his face-pocket) are plastic. And everything is gloriously labeled “BPA-Free!” but, still, my mommy vibe was tingling and I decided I needed to know more about plastics.

(Okay, really what did it was that he got a plastic sippy cup, and I asked Husband to wait on removing the packaging ’cause we might not keep it. I knew glass was better, so we got him a glass training cup, but when I started to tell someone else that I wasn’t super thrilled about all the plastic in his life, and got the half-eye-roll, I decided I really needed to know what I was talking about.)

Keep reading (or skip to the bottom) for a petition that needs your signature and a sweet giveaway!

How To Make Plastics

Plastics are made from oil. Oil is a carbon-rich raw material, but synthetic materials are added and manipulated to make an almost endless variety of plastics that vary in color, texture, strength, flexibility, etc.

What are Endocrine Disrupters?

Some of the synthetic pieces that get added to plastics qualify as, “endocrine disrupters.” Endocrine disrupters send false signals to the body, telling it that the hormone estrogen is present where it is not. They are also sometimes referred to as “estrogrenic activity (EA) chemicals,” or chemicals having EA.

These chemicals are pulled from plastics, either by direct contact with a person (i.e. chewing on plastic), or by contaminating food and beverages that are stored in them. They can cause a variety of developmental and reproductive problems, and children – from the unborn to toddlers – are especially vulnerable to them.

What is Bisphenol A (BPA)

BPA is probably the most famous example of an endocrine disrupter. It was used in polycarbonate plastics, which break down over time, releasing the BPA.

Human testing of endocrine disrupters is very limited, but in lab tests with other mammals, even low level exposure to BPA may affect the brain and neurologic development of fetuses to early puberty, and increase the risk of breast cancer, obesity, and behavioral and developmental problems.

“There is growing evidence in animal studies that exposure during fetal growth affects the development of reproductive systems and, in offspring, can lead to neurological problems. BPA has also been linked to prostate and breast cancer.” – Dominique Browning, The New York Times, 2011

BPA exposure has also been linked to:

  • Increased risk of prostate cancer
  • Regional decline in sperm counts
  • Abnormal penile/urethra development
  • Early sexual maturation in females
  • Increasing prevalence of Type 2 diabetes
  • Weakening immune system

In July 2012, the FDA banned its use in baby bottles and children’s cups, although by that time manufacturers had caved to consumer pressure and weren’t using it anyway.

But Wait! There’s More! – Other Chemicals in Plastics

BPA isn’t the only endocrine disrupter found in plastics, and it’s not even the worst one. Other EA chemicals are being used to replace BPA in plastics – even in baby bottles and sippy cups – so nothing has really changed. These other chemicals haven’t been tested or protested as widely as BPA, so no one is doing anything about them.

In 2011, the Environmental Heath Perspectives published the results of an extensive study that tested over 500 pieces of plastic – from food packaging to toys, housewares to BPA-free baby bottles – widely available from common retailers – WalMart, Target, Trader Joes, etc. – for EA chemicals. Their results?

“Almost all commercially available plastic products we sampled—independent of the type of resin, product, or retail source—leached chemicals having reliably detectable EA, including those advertised as BPA free. In some cases, BPA-free products released chemicals having more EA than did BPA-containing products.” – EHP, 2011

Products that did not leach EA during initial tests, did so in later testing, after being exposed to natural stressors like sunlight, microwaves, or high temperatures in a dishwasher. Products that did produce EA chemicals, did so “more readily” after being stressed.

The scientists conducting this particular study did not attempt to identify or classify individual EA chemicals in the plastics, because it doesn’t really matter.

“A single part may consist of 5–30 chemicals, and a plastic item containing many parts (e.g., a baby bottle) may consist of ≥ 100 chemicals, almost all of which can leach from the product, especially when stressed.” – EHP, 2011

Health-related problems linked to the EA chemicals in their study (as observed in mammals) include:

  • Early puberty in females
  • Reduced sperm counts
  • Altered functions of reproductive organs
  • Obesity
  • Altered sex-specific behaviors
  • Increased rates of some breast, ovarian, testicular and prostate cancers

The study also observed,

“Fetal, newborn and juvenile mammals are especially sensitive to very low (sometimes picomolar to nanomolar) doses of chemicals having EA.” – EHP, 2011

BPA-free is a step in the right direction, but it doesn’t mean that plastics are safe options for food and/or beverages, or toys, especially for children and pregnant or nursing women.

UPDATE: A new study, released in December 2014, has linked the chemicals leeched by plastic food containers in pregnant women to “substantially lower IQs” in their children, when tested at the age of seven. “We advise them to avoid microwaving food in plastic… [and] to store food in glass containers rather than plastic ones.”

The Critics

There are, of course, those who disagree. Namely, the plastics industry:

“The plastic industry says the chemicals leach only in trace amounts that are quickly cleared from the human bloodstream.” – Juliet Spurrier, MD, Baby Gear Lab, 2012

Arnold Schecter, a public health physician at the University of Texas School of Public Health in Dallas, expressed hesitation as well:

“It was a lab study, for one thing, so it will be important to see if other researchers can replicate the findings. It’s also not yet clear what doses of chemicals could be expected actually get into people and what the real-world health implications might be.” – Emily Sohn, Discovery News, 2011

Maybe it’s not a big deal – like lead paint and asbestos were once not big deals – but I don’t really want to submit my son as a test subject. Someone else can figure that out.

What To Do About Plastics?

I’m a working mama with a house and a husband, and not a lot of time for complicated strategies right now, so my plan is to avoid plastic as much as possible – especially where it involves the baby.

Plastic Food Containers

We got this great EIO toddler training cup for El Meatball about a month ago. It’s essentially a lid and a silicone sleeve on an 8-oz canning jar. You can get the whole thing, or you can get sets of just lid/sleeve if you already have jars. No, it’s not spill-proof, but I’m learning that toddlers, in general, are not spill-proof. There are lots of other options for glass or metal bottles and toddler cups.

mason bar company lidUPDATE: Another one of my new favorite options are The Mason Bar Company lids (available in a variety of great colors and two sizes) and Glass Dharma (or paper) straws. There are about a half dozen of these lids in our house now. I love my Glass Dharma straw. I did initially get one for the toddler, but he likes to throw things and it got lost. I replaced it (hello, they offer a LIFETIME GUARANTEE – they will replace your straw no questions asked), and then he dropped the cup up-side-down and snapped the straw. So we’re using paper straws for now until he’s ready for a glass one again.

If you must buy plastic, try to avoid recycling codes #3 (polyvinyl chloride – PVC), #6 (polystyrene), and #7 (other – usually polycarbonates like BPA).

If you’re not ready to get rid of the plastic dishes, cups and food-storage containers you already have, keep them out of direct sunlight, out of the microwave, and out of the dishwasher. If they get worn, cracked, or scratched up, get rid of them (or find some other use for them – craft storage, catch-alls, drawer organizers, etc.).

Canning jars make great substitutes for food storage or beverage containers. You can get metal or glass water bottles, and there are several options on the market for glass food storage.

Plastic Toys

Maybe a second priority after food stuffs, but I’m sure my toddler isn’t the only one who carries toys in his mouth. Some of them probably probably spend as much time in his face as the food that used to wait in his plastic bowls. So ya, I’m that mama now. Roll your eyes all you want.

There is no shortage of fun, safe, educational toys that are made from wood or recycled materials, and are totally chemical-free. And if we’re being honest, they’re usually much cuter too.

Talk to Manufacturers

BPA was removed by consumer demand before the FDA made it official. So talk to manufacturers. Nothing speaks louder than money, so the more people who know and refuse to buy plastic cups and dishes for their kids, the more motivated manufacturers will become. So share, post, pin, tweet – get the information out there, and encourage your friends and family to skip the plastic.

It doesn’t hurt to send a note either. Big companies may only notice a dip in sales, and they’ll come up with all kinds of possible explanations. There’s a Contact Us link on everyone’s website, though, so send a quick note and explain. Not great with words? Here’s a little something you can cut and paste if you want:

To Whom It May Concern,

I’m a mother/father, and have been a customer of yours in the past, who was excited about the self-regulation of BPA in your products in recent years. You may be aware that recent studies continue to find substantial traces of other EA chemicals in plastics, though, even BPA-free plastics. Those same studies have also proven that there are synthetic materials that can be used in the production of plastic that are not endocrine disrupters. 

I just wanted to send a note of encouragement, in hopes that your company will look into safe production methods for your products. I will not be purchasing plastic for my children again until I find products labeled “EA-Free,” and will be encouraging my friends and family to do the same.

Thank you

    So I started with sending a message to Tommee Tippee cause those are the bottles we use. I figured it wouldn’t hurt to send to Gerber & Munchkin too. And to keep going I also emailed Ameda & Medela since they are know for breastpumps, parts, bottles, and storage that’s all plastic. Of course the petition was signed too.

    I am curious how well the glass sippy cup holds to being dropped on the floor. Cause my Bella loves dropping her cups.

      I don’t really let the Meatball carry it around the house for that reason (and because it’s not spill-proof, and he likes to turn it upside-down). It stays by his chair on the table, so he uses it during meal/snack time, and I try to carry it to the coffee table if we’re in the next room so it’s available when I’m near him and can help him use it.

      He’s dropped it a few times, and it’s fallen off a couple of counters, and has been fine. The silicone sleeve helps a lot – to protect it and, if it did break, to contain the mess. It’s not a cheap glass jar on the inside – it’s an 8 oz canning jar, so even if it does break, I can just slide another jar into the sleeve and be fine. 🙂

    I signed the petition. I don’t have young kids anymore but I’m appalled that manufacturers would use such materials for anything that would get near children.

      Word. Especially when safe options for plastic production are so readily available!

    Signed the petition! But, for the record and as an appeal to pray for our leaders which includes CEO’s, manufacturing is based on science and science is based on knowledge. Therefore, when knowledge changes (remember what the bible says about this in the last days?), so does science. Asbestos is a good historical reference for this (along with tar and nicotene). But, you probably already know this. Stick with the Bible and what it reveals, remembering always to pray for those in authority. Mike
