What’s the Deal with BPA?

And why am I seeing "BPA-free" stickers everywhere?

What is it?

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. 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. Many of them are used in the same way that BPA is and have very similar health effects. A common replacement is bisphenol S, or BPS.


What can it do to me?

BPA is a synthetic chemical that looks like estrogen to your body. It has been shown to screw with hormones including testosterone and thyroid hormones. Because of this, BPA has been tied to a large range of health problems like breast cancer, reduced sperm production, infertility, heart disease, early onset of puberty in girls, diabetes, and obesity (1). There is also concern about BPA's effect on brain and behavioral development in fetuses, infants and children (2, 3).

Where is this stuff?

BPA is all over the place. It is well known for being using in plastic containers like reusable water bottles and food storage containers. It is also frequently used in the lining of aluminum cans, like for canned beans, tomatoes, or soups. Other places BPA may be lurking is in receipt paper, electronics, dental sealants and orthodontic products, PVC, and sports safety equipment (think helmets, shin guards, wrist guards, etc.).

When products containing BPA, or any of the other BPA replacements, are heated, the chemicals can get into the food and water they are touching. This means it is more likely to leach into (leave the container and enter) food that is fatty - things like creamy and cheesy sauces or soups, meat, oily dips, leftover fries, and baby formula. It also leaches into acidic foods - like canned tomatoes, pineapple, and mandarin oranges.

How can I stay safe?

  1. Limit the amount of plastics that come into contact with food or water in your life. Try to choose glass, ceramic, or stainless steel food storage containers, water bottles, and baby bottles. Make sure any metal containers or bottles are not lined with resin (you can usually feel a waxy coating on the inside if they are). Remember, if a plastic product is marked "BPA-free" it is not necessarily safer: it is possible it contains a BPA alternative, such as BPS, which is chemically similar to BPA, and that scientists are starting to show have the same negative health effects.
  2. Avoid canned food as much as possible. If fresh produce isn't an option, frozen is better than canned (this article explains why). When you are looking for things like packaged tomatoes or fruit, look for options in glass jars or cartons - the papery boxes used for soups and other products.
  3. Never microwave in plastic! Microwaving makes it easier for the BPA to leave the container and get into your food. Instead, put your leftovers on a plate, then microwave them, and eat from the plate.
  4. Say no thanks to receipts. According to Johanna Rochester, PhD, Senior Scientist from The Endocrine Disruption Exchange, "BPA that coats the receipt paper is absorbed through the skin. If you need to keep them, store them in a ziploc bag, as BPA can transfer to your wallet, money, and purse. Do not let children play with receipts or put them in their mouths. If you work in the service industry, wash your hands often (do not use hand sanitizer, as this can increase absorption) and ask your employer to provide latex gloves."

The good news?

BPA is known to leave your system pretty quickly. This means that if you stop coming into contact with it, most of the BPA will be out of your system within a day or two. Making small changes really does add up!

Not so fast...

Although BPA leaves the body quickly, we are constantly being exposed to it. BPA is especially harmful for babies and pregnant women. These are both times in life that are considered "critical periods" because so much is changing and growing quickly.

"During this time, hormones send signals to the fetus or baby and direct how the cells and systems grow and develop. BPA can disrupt this signalling and can alter how cells develop and reprogram systems. This reprogramming can manifest as diseases or disorders when the child grows up. Some studies show that if pregnant women are exposed to endocrine disruptors like BPA, it can lead to obesity in their children," said Dr. Rochester.

What's crazier is that things happening to you can even affect your baby's baby.

"Exposure to BPA can also affect future generations--your grandchildren and even great-grandchildren. This is because all of the eggs of a baby girl are present before she is born, and BPA can affect her eggs through epigenetic changes--permanent changes in how a gene works that can be inherited over generations. This can also happen in males," explained Dr. Rochester.

So, these tips are even more important for women who are pregnant, couples trying to get pregnant, and parents with infants, and those who are breastfeeding.

Environmental Factors May Have a Bigger Impact on Fertility than You Think

Breaking Down the Science and Ways to Limit Harmful Exposures

Trying to get pregnant should be an exciting time of planning for the next stage of your life, not one full of doctors visits, constant testing, and worrying about body temperatures. But, if you and your partner are struggling with infertility, you are not alone. According to the CDC about 12% of women have impaired fecundity, which is another way of saying that they are having difficulty getting or staying pregnant (1) [there are no statistics on infertility in men, but there is science showing that overall sperm count is decreasing(14)]. And, the science is clear, environmental factors definitely impact reproductive health - for both men and women. Some of the biggest impacts come from air pollution, pesticides, and endocrine disrupting chemicals (2), which are in all sorts of products and affect the way hormones interact with your body.

9 Stainless Steel & Glass Tumblers

For iced coffee, iced tea, and smoothies on the go

Getting iced coffee in a plastic cup with a plastic straw is a lot harder to do after watching that video of a plastic straw being removed from a turtle's nose. Plus there is also that pesky condensation that creates a pool of water at the bottle of your cupholder or on your desk. So we found the 9 best reviewed stainless steel and glass tumblers, so that you can have your iced beverages in style this summer. Many of the brands have different sizes ranging from 20oz to 30oz and variety of colors. We prefer stainless steel or glass because many of the acrylic or plastic tumblers may have chemicals similar to BPA. We also link to some stainless steel straws because not all of these tumblers come with straws. And if you're like us, drinking iced coffee through a straw is just synonymous with summer.

Easy Ways To Keep Your Car Smelling Fresh Without the Synthetic Scents

Cause Traditional Car Air Fresheners Are No Good For Your Health

Those little tree-shaped air fresheners dangling from a rear-view mirror or air vent clip-ons may feel festive, but most car air fresheners can be bad for your health. They seem so innocent, so how is that possible you might ask?

One of the biggest issues with these products is the mystery behind what goes into them. Believe it or not, It's actually hard to be 100% certain about what chemicals are in air fresheners. There's a ton of secrecy into what actually goes into a fragrance product because companies can claim their ingredients are trade secrets. We definitely can't say a product is safe if we don't even know what is used to make it.

However, we do know that most air fresheners are made up of a ton of synthetic fragrances. There are literally thousands of chemicals manufacturers can choose from when making a product with synthetic fragrance. And a lot of these chemicals are known to have negative impacts on our health. (1)

On top of that, fragrance in air fresheners usually contain both phthalates and volatile organic compounds (VOCs) (2). Although these chemicals can make scents powerful, they can also be allergens that cause coughing, headaches, and runny noses (2). Phthalates are also hormone disruptors and VOCs can be carcinogens. We definitely don't want to be constantly breathing in those chemicals, no matter how good they might smell!

The amount of space inside your car is also a reason we don't like traditional car air fresheners. A smaller space = more concentrated exposure, and since you probably have your windows closed 90% of the time, a car is one of the worst places to keep a strongly-scented product.

Luckily, there are easy, nontoxic ways to make your car smell fresh! You can keep a container filled with baking soda or a baking soda freezer pack hidden somewhere. Baking soda is a completely natural way to eliminate odors and a box is only a couple of dollars! Using scents from natural sources are also a great way to add a little freshness to your car. You can put a few drops of an essential oil onto a clothespin or another wooden item and leave it somewhere in your car (3). When the smell goes away, just replenish with a few more drops of oil! If you prefer something a little more contained, we also love putting satchels of lavender or rose petals around our car.

But perhaps the easiest way to get rid of a bad smell is to simply roll your windows down! Maybe rolling down the windows will help make your commute a little more relaxing too.
