BPA is not being used anymore, but what do we know about the new liners?

Is Canned Food Safe from BPA Now?

Food

When it’s 7pm and you haven’t thought about dinner yet, heating up a can of chunky stew or throwing a can of beans into a cheesy burrito sounds like the best idea ever. By now, you’ve probably heard about BPA in canned foods, but many cans now say “BPA-free” on them. Hurray for that, right?! Every can still needs a thin liner inside so that the food doesn’t corrode the metal from the inside out. So if they are not made with BPA, what are these new liners made of? And does it mean that canned foods are safer to eat now?

What is BPA?

BPA, or bisphenol A, is a chemical that is often used in plastics to make them clear and strong. It is also in epoxy resins that can line water pipes and food cans, and is used in receipt paper (1). Although BPA is the most well-known bisphenol, there are dozens of other bisphenols (often called BPA replacements) out there that are chemically similar to BPA.

BPA is one of the better known endocrine disrupting chemicals (EDCs). These chemicals look like and act like hormones in the body, which confuse the endocrine system and cause disruption of its normal functions. Since the endocrine system is responsible for metabolism, growth and development, reproduction, and so much more, scientists are finding out more every day about the harmful health effects of EDCs.

BPA in Canned food

Canned food has been around for a long time and since the 1960’s, a thin epoxy lining made with the chemical BPA has been used to protect the inside of the can from corroding. Corroding metal is not good, so a liner is definitely needed in order for canned food to have a good shelf life.

There were two problems though. First, more and more studies piled up showing the harmful endocrine disrupting effects of BPA (2). Secondly, many studies showed that BPA moves from the can lining into the food that is eaten, and that things like acidity, heat, and fat affected how much BPA ended up being in the food (3,4). As a result, there was more and more pressure to remove BPA from can linings.

In fact, reports have shown that there has been a decline in can linings with BPA. The Center for Environmental Health found a huge decline from 2017 to 2019 in canned foods that had BPA linings. In 2019, their tests showed that about 95% of cans tested free of BPA. In fact, the Can Manufactuer’s Institute reports that their industry statistics indicate that more than 95% of all U.S. food can production has transitioned out of BPA to alternative liners (5).

New Canned Food Linings

It’s clear that canned food has largely moved away from BPA, but what are they using in new can linings? That part is less clear. The new linings are made from either acrylic, polyester, non-BPA epoxies, polyvinyl chloride (PVC) copolymers, or olefin polymers. Which one depends on the manufacturer. A 2016 report by several nonprofit groups Buyer Beware: Toxic BPA and regrettable substitutes in the linings of canned food notes that many of these new linings are not great alternatives. PVC is not a great substitute because it’s made from vinyl chloride, a known carcinogen. And many of the acrylic linings include polystyrene (hello styrofoam!), which is also a possible human carcinogen. Adequate testing to ensure that these new linings are safe for food have not been done. And it’s probably no surprise that neither PVC or polystyrene are great for the environment!

Even some of the newest liners, like olefin polymers, which are partially derived from plants, have not been completely studied for safety, many times because their formulation is not publicly available.

Moreover, there are only a couple of companies that specify exactly which BPA free liner they have moved to. So, if you see a can with a BPA free symbol on it, you won’t know what they are using instead.

The Bottom Line on BPA in Canned Food

So the bottom line is that yes, canned foods are largely safe from BPA now thanks to the voices of countless consumers and health advocates. But there is more work to be done to ensure that canned foods linings that are used today are safe. Here’s what you can do to best protect your health:

  1. Write to companies and ask them what linings they use on their canned food products and ask them to show you safety data.
  2. Buy frozen produce and fruits. Food is frozen before it is packaged and frozen food packaging is generally made of safer plastics.
  3. Explore canned food alternatives such as glass jars and Tetra-paks.
  4. Shop the bulk and dry goods bins and make staples like beans from scratch. Freeze small portions in the freezer for easy accessibility in the future.

Non-Toxic & Eco-Friendly Backpacks

The most sustainable backpacks for toddlers, preschoolers, grade schoolers, teens, and adults!

Updated for Fall 2021!

As soon as August rolls around, all we can think of backpacks! A new backpack is often the most exciting thing on the back to school shopping list, especially if the one from last year is torn to shreds or not big enough anymore. Many backpacks are made from harmful plastics like PVC, which contains phthalates, and many times they are treated with a PFAS (Teflon-like) finish. This is why we searched high and low for backpacks that are not only cute and functional, but are also good for the environment. Our backpack recommendations are all phthalate, PVC, and lead free. We also looked for backpacks that are made from recycled water bottles, GOTS certified organic cotton, or that feature a PFAS-free water repellent.

PFAS and PVC Free Adult Rain Gear

Stay protected from the elements

As spring approaches, you may be thinking of upgrading your rain gear before the rainy season hits. Most rain gear can contain harmful chemicals like PFC/PFAS or PVC, which is not something you want on your body. PVC (Polyvinyl Chloride) is a common plastic that is used in hundreds of places, but it's often used in rain gear to make it more waterproof. PVC on its own is not inherently toxic but it is extremely brittle, which is why phthalates are often added to make it stronger. Phthalates are harmful endocrine disruptors that have been linked to cancer, infertility, heart disease, and obesity.

The other group of chemicals that we want to steer away from is PFAS or PFC (i.e. Teflon-like chemicals). These chemicals have extremely tight bonds between the atoms, which means nothing can get past them. While this makes them great waterproofing agents, it also means these chemicals basically don't break down over time. These "forever chemicals" are also found in nonstick cookware, stain-resistant fabrics, and even take-out containers. Because these chemicals are found in so many common products they eventually end up in our environment polluting the water and soil and staying there forever. PFAS have been known to cause serious health problems like decreased fertility, increased cholesterol levels, harming the growth and development of children, and lowering immune system function.

That's why we found the best rain jackets and rain boots for adults! These boots and jackets are free from PFAS and PVC but will still keep you protected from the elements.

PFAS and PVC Free Kids Rain Gear

Rain, rain, go away... unless you're wearing one of these jackets!

For most people, the arrival of spring also means the arrival of the rainy season. And if you have kids, and are having an increased number of outdoor playdates due to covid, you probably need to stock up on some new rain gear. Remember, there's no bad weather, just bad clothing! But before you go out and purchase just any rain gear, you should know that a lot of the common gear you see at the stores could be made with toxic chemicals.

The two chemicals that we want to steer clear of are PVC and PFAS. PVC or otherwise known as Polyvinyl Chloride is a super common plastic that is used in hundreds of places, but it's often used in rain gear to make it more waterproof. PVC on its own is not inherently toxic but it is extremely brittle, which is why phthalates are often added to make it stronger. Phthalates are harmful endocrine disruptors that have been linked to cancer, infertility, heart disease, and obesity.

PFAS have been known to cause serious health problems like decreased fertility, increased cholesterol levels, harming the growth and development of children, and lowering immune system function.

I think it's pretty clear that it's best to stay away from any rain gear that uses these chemicals. They are not good for the planet, nor for your health. We definitely think PVC, PFAS (PFCs) need to be avoided, which is why we rounded up our favorite PVC and PFAS free kids rain gear so you don't have to worry this Spring!

Real talk— polyvinyl chloride (or PVC for short), seems to be in practically everything, doesn't it? If you walk down a random aisle in a store, you can find this material in upholstery, shower curtains, toys and even school supplies. You might be thinking, if it's in so many things (including items for children), it should be safe right? In reality, the answer is no. BUT, don't fret, since there are simple, yet effective ways to avoid PVC in your everyday life.

Don’t let a PVC Yoga Mat Ruin Your Om

Nama-stay away from this material

Yoga is the perfect way to destress while still giving your body a good workout. It's as beneficial for the mind as it is for the body! Plus, it doesn't hurt that you don't have to leave the house to practice it. But while yoga might be good for your health, your yoga mat could have hidden health risks.

The Problem With Yoga Mats

When you think of a yoga mat, you probably picture a soft, sponge-y material that you can easily roll and bend. Turns out, most yoga mats are made from polyvinyl chloride- otherwise known as PVC or vinyl. While this material is good at proving grip and padding, PVC is actually a type of plastic. PVC starts out as a really hard material, but becomes flexible when phthalates are added during production. Your super flexible yoga mat probably has a lot of phthalates added to it, which means you could be exposed to endocrine disrupting chemicals during your downward-facing dog. Yoga mats are also known to peel and flake as they age. These little crumbs could end up all over your house and you could be exposed to harmful chemicals even when you're off the mat!

Plus, the production of PVC is horrible for the environment and can be a big source of pollution. It has also been known to contribute to climate change. That's just not a material we want to purchase!

What You Can Do

Never fear! There are tons of PVC-free yoga mat options out there. Try looking for a yoga mat that's 100% made from natural materials like cotton, cork, or natural rubber. These materials will still provide padding while reducing your exposure to harmful chemicals. Jute is another great option, but be sure to avoid any mats that mix jute with polymer environmental resin (PER), which contains PVC (1).

You can also look for yoga mats that specifically say they're PVC-free, but make sure to carefully check out the materials the mat is made up of. Just because it's advertised as PVC-free doesn't mean it's made from better materials.

If you have an old yoga mat you're no longer using, call your local recycling facility to see whether or not they could recycle it. But be aware that it might be difficult to find a facility that will accept it, since PVC is notoriously hard to recycle (2).

Are Foam Play Mats Safe For Babies?

Don't let tummy time be toxic time

Squishy foam mats or those large colorful floor puzzles can seem like a great way to keep your baby comfortable during tummy time or cushion your clumsy toddler's falls. As useful as these play mats are, it is important to choose the right material before buying! Some mats are made of substances that can harm your baby's health, and manufacturers are often not transparent about what is in their "foam" products. The safety of products manufactured for use by children is particularly important, since children are especially vulnerable to toxic exposures. Here is what you need to know to make an informed, healthy choice for your child.

What's in Foam Baby Mats?

Foam mats popular in homes, schools, and even childcare centers. But what is in the foam? Many foam materials like those used for baby mats, yoga mats and in gyms are usually made up of polyvinyl chloride (PVC), polyurethane, or EVA. But it's almost impossible to find a more detailed description than that. Even extensive research doesn't turn up many results.

Polyvinyl chloride and polyurethane foam in baby products are less popular than they once were, and EVA is often looked at as a less toxic alternative. However, there are problems with all three materials. PVC, aside from being a plastic polymer that can bind and spread other toxics, is often also treated with phthalates. This additive, used for increased flexibility, is a known endocrine disruptor with harmful effects on many body systems (1). Polyurethane, although itself is non-toxic, is flammable and typically contains added flame-retardants like PBDEs that can be detrimental to child development (2,3).

EVA, typically advertised as the non-toxic choice often tests positive for formamide, another toxic chemical. Although some EVA mats are advertised as formamide free, this doesn't necessarily mean what it says. "Formamide free" means that there may be trace levels of formamide, but the levels are low enough that companies are allowed to market their products as free of the chemical (4). EVA is definitely a better option than PVC or polyurethane, but with any of these foam materials, it is very difficult to know what chemicals you could be bringing into your home.

Safer Alternatives

If you want to ensure your child will not be exposed to any toxics from their play mats, an organic cotton mat is the best choice. There have been a number of studies showing that foam mats use at home, in childcare centers, and in gyms are associated with significantly increased exposure to a wide range of toxic chemicals, like the ones mentioned previously. These chemicals are associated with many adverse health and developmental problems including neurological issues, and reproductive and liver toxicity (5).

As research becomes more robust, we are finding that more and more household items contain toxic chemicals or materials. Currently, there are no strong laws that ban the use of chemicals in foam mats and manufacturers are not required to disclose their composition. So, it is up to you to be proactive and keep your little ones safe from harmful exposures.
