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.

Is Your Artificial Christmas Tree Toxic?

Tips to reduce your exposure to these hazardous chemicals

Artificial Christmas trees are becoming increasingly popular for families. They're seen as being convenient since they don't shed needles and can be reused year after year. Because they can be reused, families tend to save money by choosing artificial trees over a real one. A study from the The American Christmas Tree Association (yes that is a real and reputable organization!) performed a life cycle analysis and found that one artificial tree that's reused for eight or more Christmases is more environmentally friendly than purchasing a real tree each year (1). The study also found that Christmas trees, both real and fake, accounted for a tiny part (< 0.1%) of a person's annual carbon footprint.

But are artificial Christmas trees as good for your health as they are for your wallet? The majority of artificial trees are made using a plastic called polyvinyl chloride (PVC) and lead, which is used to stabilize PVC (2). The lead in the trees break down over time and forms lead dust. These particles are released into the air and can cause health issues, especially in young children. Most people do not realize that artificial trees contain lead, and only California requires a lead warning label (2). It is estimated that there are 50 million households in the United States that own artificial trees with lead in them (3).

Don't panic! If you are an owner of an artificial Christmas tree made out of PVC, there are precautions you can take to reduce your family's exposure to lead.

  1. PVC releases more gases when it is first exposed to air. They also release gases as they degrade. A good way to reduce the amount of lead in your household is to take the tree out of the box and air it outside when you first purchase it (4).
  2. If you have used your artificial tree for many Christmases, you may want to consider purchasing a new one. PVC tends to weaken and degrade after nine years (4). Newer artificial trees do not leach as much lead as older ones.
  3. Light cords that come with your artifical tree are prone to have levels of lead that exceed the limit set by the EPA (4). It is recommended that you wash your hands immediately after touching light cords. And definitely don't let young children handle cords.

If you're currently tree-less and in the market for an artificial one, consider purchasing a tree made out of polyethylene. This plastic is safer than PVC and does not leach lead. Additionally, trees made out of polyethylene tend to be more durable than PVC trees.

While artificial PVC Christmas trees don't pose a high health risk overall to the general population, it's very possible for young children to have severe negative health effects (3). It's important to be aware of the health risks that go along with trees made out of PVC, and the ways to avoid lead exposure for yourself and your family this holiday season.

Sometimes it may feel like everywhere you turn, there's some sort of junk food being advertised—whether that's cupcakes or fries or deep fried things on a stick. And more than sometimes, you have a child begging you for a sweet treat or sugary drink. It can feel like a daunting task at times to encourage and foster healthy eating. While we know there are many factors that influence a child's food choices, here's one that you may not have thought of.

Avoid These Stressful Ingredients the Next Time You Relax with a Bath Bomb

We don't need these chemicals messing with our #selfcare

December means it's time to start thinking about those stocking stuffers or Chanukah gifts for your loved ones. What's better than a bath bomb to relax and take in those sudsy, therapeutic fragrances? Bath bombs can also get your kids to bathe without putting up a fight. They're basically magic! But, have you stopped to think what else they are putting in those bombs to make those suds glisten and fizz?

What's in a Bath Bomb?

It turns out, there can be a whole range of questionable chemicals packed neatly into those appealing little bombs. It's hard to tell exactly what's in each bath bomb because the ingredients vary widely among manufacturers, but fragrances, artificial colors, boric acid, and glitter are some common ingredients.

Fragrance is never a welcome sight on the ingredient list. The FDA does not require companies to disclose ingredients used to make fragrances in products like bath bombs in order to protect company "trade secrets (1)." Many synthetic and natural fragrances also include such hormone-disrupting chemicals as phthalates, which can be absorbed through the skin and have been found to pose specific risks for pregnant women and children (2). Studies have also linked health effects of phthalates to miscarriage, gestational diabetes, reduced IQ, and ADHD with increased exposure to phthalates.

As for dyes, the evidence is limited when it comes to FDA approved dyes readily being absorbed through the skin. However, one study found that certain dyes may be absorbed after shaving (3). Also, young children often swallow water while bathing and ingestion of some of these chemicals for young children is definitely not recommended!

Boric acid also has some side effects that you may not want to risk. It can be absorbed through the mucous membranes and has been linked to hormone disruption and developmental and reproductive toxicity (4). And then there is glitter, which is just more plastic that can end up in our lakes, rivers, and streams.

Alternatives and DIY Recipes

While there may be harmful ingredients in some bath bombs, you don't have to give them up! It's easy to avoid these ingredients with just a little extra effort. You can choose to purchase "fragrance-free" or "phthalate-free" bath bombs, but making your own bath bomb is super easy. Here are also some DIY recipes to try at home.

Ingredients

  • 1 cup baking soda
  • ½ cup citric acid
  • 1 tablespoon cornstarch
  • 1 teaspoon cream of tartar
  • ½ cup finely ground sea salt
  • 1 ½ teaspoons almond oil (or apricot oil)
  • ½ teaspoon coconut oil
  • 1 tablespoon of witch hazel
  • 1 teaspoon beet root powder
  • wild orange essential oil
  • rose essential oil

Directions

  • Blend all dry ingredients in a bowl.
  • Blend wet ingredients in another bowl.
  • Combine all ingredients.
  • Place in mold of choice or just form a ball about 1-2 inches in diameter.
  • Allow the bath bombs to dry for approximately 1-2 days.
  • To use, place bath bomb in the bath.
  • To store, place in airtight container. Storing in a refrigerator can allow the bath bombs to keep for about 3 weeks (5).

The Hidden Risk in Store-Bought Slime

Avoid this hazardous ingredient with our own DIY slime recipe

Slime seems to be the hottest new toy for kids. They love that it's a tactile toy they can squeeze and smash. But before you rush out to buy a new tub of gooey slime on your next shopping trip, have you ever wondered what's actually in it? Turns out, there's a not-so-kid-friendly ingredient lurking in many slime products sold in stores, as well as in some DIY kits and recipes.

What's So Bad About Boron?

Boron is a chemical commonly used in many brands of slime, DIY kits, and some DIY recipes to give it that rubbery texture. While it may feel fun, it's actually not great for our health. Boron is an acute eye, respiratory tract, and nasal irritant and is harmful if swallowed (1). If ingested, it can also cause nausea and vomiting (2). Long-term exposure to boron can also cause negative reproductive health effects (3, 4). The problems with boron don't stop once you throw slime away either. It turns out that boron lasts a long time in the environment and has hazardous effects on aquatic life (5).

To make matters worse, there's a lot more boron in slime than there should be. The U.S. Public Interest Research Group (PIRG) recently tested different brands of slime and found concentrations as high as 4700 parts per million (ppm) of boron, (6) which is more than fifteen times the allowable level for toys sold in the European Union (300 ppm for sticky/liquid toys) (6). Canada, Jordan, and the United Arab Emirates have even instituted policies limiting or banning boron in children's toys (6).

Safe Slime

Luckily, it's easy to make your own boron-free slime. We like this recipe for full-proof slime that substitutes boron/borax (a boron compound that's found in a lot of other slime recipes) with cornstarch and school glue. We guarantee your kids will still have hours of fun with this non-toxic slime!

Fluffy Volcano Slime

  1. Pour 1/4 cup white school glue and a 1/2 cup of cornstarch in a bowl
  2. Add 3 drops of food coloring (optional)
  3. Mix well
  4. Knead it with your hands for 10 minutes
  5. Heat it in the microwave for 20 seconds
  6. Let it cool, then knead it for another 10 minutes (7)
