Plastics & BPA
May 9, 2008
Plastic polycarbonate bottles such as Nalgene bottles are still popular as drinking water bottles. I should know. I just bought 3 more – one of which is a pretty cool sippy bottle for my son. (Note: now Nalgene is phasing out those bottles & replacing them.) I recently learned that polycarbonates in those and other bottles release a chemical known as bisphenol A (BPA). Then, I learned that 90% of all baby bottles are polycarbonates, which includes the brand we own — Avent. So, what’s the big deal? They’re still selling them, so they can’t be that bad, right? Not exactly…
Even though the plastic industry safety studies find no significant health effects from typical daily doses of BPA, 90% of government studies found harmful health effects to children and expecting moms as well as male sexuality and reproduction, according to Dr. Colleen Huber. She goes on to state that BPA acts as a “xenoestrogen,” which mimics the female hormone estrogen with the exception of the following: 1) it’s foreign to the body (which is what “xeno” means) and 2) it is much more harmful than our natural estrogen for both males and females. Breast cancers are much more of a risk in women who carry a high amount of xenoestrogens and both sexes are subject to a huge range of other harmful health effects. The most far-reaching effects are birth defects and miscarriages. Another effect is a disruption of beta cell function in the pancreas, which creates a pre-diabetes type condition of high blood insulin and insulin resistance. So it seems that none of us are safe from the affects of BPA.
A recent Canadian news source had the following to say:
“Bisphenol A manufacturers have said the trace amount leaching into food and beverages isn’t dangerous to people because it’s quickly metabolized into a form that loses its ability to act like a female sex hormone.
While the authors of the new assessment agreed that people break down some of the bisphenol A they absorb, they said since so many plastics and other products containing it are in use that “virtually everybody” in developed countries has chronic, low-level exposure to the chemical and measurable amounts of its biologically active version.
Typical readings are about two parts per billion in blood. Although this is an extremely small amount, hormones are active at this level, and at even lower concentrations.
Based on the amounts being found in people and what is known about the metabolism of bisphenol A from animal experiments, it also appears that human exposures are above the current U.S. safety limit, according to the assessment.
Now I should note that not all plastics contain BPA. We should mainly be concerned with plastics that come in contact with our food and water. You can learn more about plastics by reviewing the Smart Plastics Guide and matching the triangled number to what you currently own or are considering purchasing.
Here are a few items to consider for your baby. Oh, and be sure to read the San Francisco Chronicle’s article on the comeback of glass baby bottles.
1. Glass bottles. Evenflo makes them in two sizes — 4oz and 8oz. Siliskin is another brand that is totally hip. They come in 4 and 8 oz sizes as well and they have a silicone sheath that helps to prevent the bottle from breaking. WeeGo glass bottles are nice too. I believe they only come in 9oz sizes, but they are covered with a modern sleeve that will help protect the bottle from breaking.
2. Bio-plastic bottles. Born Free makes them in two sizes — 5oz and 9oz. Whole Foods and Amazon carry them as well as the company itself. Amazon even has their gift set with bottles and a sippy cup. Another option is the Green to Grow brand, which has a 5oz bottle and they’re so cute.
3. Snappies - Polypropylene breast milk storage bottles that enables moms to collect, store and feed from the same convenient container.
4. Medela breast pump storage containers and baby bottles are all made of Polypropylene, which is free of BPA.
5. Adiri Natural Nurser is made from 100% polycarbonate-free and bisphenol-a free materials that is warm to a child’s cheek, like a breast, when filled with warm milk. The nipple design helps alleviate nipple confusion for breastfeeding babies. Shaped like a breast, they encourage the same type of open-mouthed latching that is required for breastfeeding, making bottle feeding and breastfeeding more easily interchangeable. They come in three stages for three different flow rates. Each stage holds 8 oz. of fluid and is dishwasher safe.
Here are a few brands to consider for sippy cups:
1. Avent Naturally sippy cup (We currently use these and are happy with them)
2. Born Free sippy cup
3. Klean Kanteen water bottle with sippy adapter & spout
4. SIGG baby water bottles
If anyone has a suggestion on any of the above mentioned brands or any other brands not mentioned that you love, please leave a comment. We’d love to hear from you!

Hello!
To add to your list of BPA-free is Babisil.
We are a company based over in the UK and design and provide Phthalate and Bisphenol-A free products for babies and toddlers, including our baby Silbottle.
The Silbottle is a clever bottle which holds a silicone inner chamber (in which the milk is contained) which collapses as baby drinks… Thus helping with colic too!
Hopefully all coming to a store near you! Claire
