More than 30,000,000 people in the US and 200 million worldwide have a Thyroid Disorder Most affected are women. Some estimates are over 50 million in US and over 200 million worldwide, and growing.

Estimates vary widely as most patients are misdiagnosed or undiagnosed because doctors don't know what they are looking for.

Thyroid disease is also an autoimmune disease. This means that over 27 million people have one or more of the over 105 known autoimmune diseases.

Thyroid Health – Is Tupperware BPA Free and Safe to Use?

Thyroid health is a fragile thing. So many environmental triggers can set off a cascade of symptoms that deplete your quality of life.

Food storage containers can be one of these triggers.

Why? Because of BPAs.

What is a BPA?

If you use plastic containers for food storage or drink from a plastic water bottle, you want to know about BPAs. It is the most widely used component in food packaging, even in canned foods.

Bisphenol A, commonly abbreviated as BPA, is an organic compound with two phenol functional groups. Bisphenol A is used primarily to make plastics, and products containing bisphenol A-based plastics have been in commerce for more than 50 years. It is a key monomer in production of epoxy resins and in the most common form of polycarbonate plastic.

Concerns about the use of bisphenol A in consumer products started being regularly reported in the news media in 2008. These “concerns” include how BPA messes with thyroid hormone and other receptors in our body depleting our health by confusing our natural, streamlined biology from working properly.

Think about this… BPA is now classified as a food additive (!),a category that requires a cumbersome and time-consuming process to make regulatory changes. Dr. Sharfstein said he hoped its status could be changed to “food contact substance,” which would give the F.D.A. more regulatory power and let it act more quickly if it needed to do so.

Too read more, find indepth research by Dr. Mercola.

“Flexible packaging” — the pouches and films your food comes in — is big money, representing a $21.3 billion per year industry in the United States that is growing by 3.5 percent annually.

And BPA is one of the biggest players in the wrapping industry.

In 2009, more than 6 billion pounds of BPA was made, representing nearly $7 billion in sales. US companies that make BPA are Bayer Material Science, Dow Chemical Company, SABIC Innovative Plastics (formerly GE Plastics), Hexion Specialty Chemicals, and Sunoco Chemicals.

There’s no real incentive for them to change because they’re making a chunk of change. But, to keep your thyroid health growing in a positive direction, you have to take care of yourself.


Boy, we all know Tupperware! They are creative, innovative and crafty. I applaud them.

And, they report that they have been, since March 2010, BPA-free! I applaud them even more!

Tupperware follows the recommendations and guidelines of governmental regulatory agencies regarding materials that may be used in our high quality products. The Company also acknowledges the attitudes of consumers regarding products containing BPA. In its continuous search for the best materials for use in its products, Tupperware has found other materials with improved performance characteristics that have been approved by regulators to be BPA free to replace polycarbonate. As of March 2010, items sold by Tupperware US & CA are BPA free. See the notice at Tupperware here.

Of course, this means that all the Tupperware you have “before” 2010 products are NOT BPA free. 🙁


Use glass. Pyrex, Anchor Hocking, or any glass container is fine. Glass does not “leach” chemicals into your food or liquids.


No matter what their products say about being “microwave safe”, and this goes for anything plastic, DO NOT MICROWAVE FOOD IN IT. PERIOD!

    I would love to buy a small griddle / pan that allows me to make gluten, dairy free pancakes or egg white omelets. Do you have a recommendation?

  • Tupperware is 100% BPA free as of March 2010. What you were reading was an old 2008 statement as they were working to remove BPA from it’s line of products. All infant products were BPA free long before that and pre 2010, products that still contained BPA were limited to a very few products that were either A) not intended for microwave use or B) not intended for the dishwasher.
    Rest assured, Tupperware is safe to use. We have a sensitive child with Autism and this is all we use now. Saves a lot of money and a lot of time.

    In chemistry classes I learned that all plastics ‘outgas’ release several chemicals (it’s not just BPA or EA’s either), are not inert,products made from them are comprised of many ingredients in proprietary combination and there are always unstable bonds at the molecular level. Depending on the type of plastic and the salinity, acidity, alkalinity,stresses and temperature it is exposed to determines migration of the component chemicals out of the plastic and into food/the environment.

    Tupperware is candid by including the following online in their 2010 Sustainability Report and they deserve kudos for that much but as a fellow low thyroid sufferer I am self limiting usage of plastics especially microware to only those rare occasions where I really am pressed for time and no longer using a tupperware container for my lunch salad at work that is typically doused with a vinaigrette (an acidic dressing that likely releases greater amounts of chemicals from the plastic container vs. a more basic dressing such as ranch which with its fat content also encourages release of chemicals from the plastic (and I grew up with Tupperware, my aunt sold it in the 1970’s and our family had the pastel bowls, cups, dark orange juice container, the goldenrod colored flour and cookie containers, lunch boxes etc!)
    Tupperware’s official statement addressing concerns over polycarbonate containers can be found if you scroll down to page 18 of the report at http://www.tupperwarebrands.com/Tupperware-Sustainability.pdf

    • kim

      Thank you Debbie!

      And yes, all the way around.

      The BPA-Free initiative is our current “we’ll keep you from the bad stuff” rally. However, there are plenty of other chemicals messing us up for sure. In 5-10 years they’ll let us know, “Oh, well, BPA-Free just isn’t good enough.”

      So, for we who are doing the best we can to sidestep all these crazy chemical based containers, use glass or stainless steel.

      Thanks again, Debbie!

    here’s more online about plastics and health:
    Quote from article:
    “What is “estrogenic activity” (EA)?

    Chemicals with estrogenic activity (EA) are those that mimic or antagonize the actions of naturally occurring estrogens. These chemicals are capable of binding with one or more of the nuclear estrogen receptors in the body.

    The best way to think of chemicals with EA is as a counterfeit key fitting into a loose lock. When these chemicals activate the estrogen receptor, they produce an increase in circulating estrogen, which in turn can cause problems such as early puberty in females, reduced sperm counts, altered function of the reproductive organs, obesity, increased rates of certain cancers and problems with infant and childhood development. (3)

    As I mentioned above, vulnerable populations such as pregnant women, developing fetuses, infants and children are especially sensitive to even very low doses of chemicals with EA. (4)

    BPA-free is not EA-free

    In the Environmental Health Perspectives study, Yaniger et al. set out to determine the estrogenic activity of commonly used plastic consumer products.

    They bought more than 500 plastic products at places like Wal-Mart, Whole Foods, Trader Joe’s, Target, and other major retailers. They selected from all categories of plastic, including tupperware containers, bags and wraps.

    Then they cut the containers into pieces, put them into liquids that contain similar chemicals found in food and drinks, and subjected them to stresses that mimic normal use, like UV light (sunlight), microwaving, or moist heat (like boiling or dishwashing).

    Their results showed that over 90 percent of the products leached estrogenic chemicals before they were even stressed, and after being stressed essentially all of the products showed estrogenic activity.

    According to Stuart Yaniger, one of the lead authors of the study:

    Baby bottles, plastic bags, plastic wrap, clamshell food containers, stand-up pouches: Just about anything you can think of that’s made of plastic that food or beverages are wrapped up in, we found this activity. It was shocking to us.

    What plastics do and don’t have EA? It’s impossible to tell.

    Perhaps the most troubling outcome of this study is that it’s currently impossible to determine which consumer plastic products are likely to have chemicals with EA, and which are not. The exact chemical composition of most plastic products is proprietary and thus not known, and a single plastic item containing many parts (e.g. a baby bottle) may consist of >100 chemicals, all of which can leach from the product.

    In light of the researchers’ finding that nearly all of the 500 plastic products they tested leached when stressed, and 90 percent of them leached even without stress, I think it’s pretty safe to assume that most plastic products you can buy in the store have chemicals with EA.

    It’s important to reiterate that this is true even with BPA-free plastics. In fact, the Environmental Health Perspectives study found that some BPA-free products had even more EA than BPA-containing products!

    Should you be concerned about chemicals with EA?

    There are still a lot of unknowns in the discussion of the EA of various chemicals in plastic products, such as the number of chemicals having EA, their relative EA, their release rate under different conditions, and their half-lives in human beings of different ages.”

  • Debbie

    You’re welcome Kim. Even though I really love the convenience, light weight and styling of plastics I hate the idea of eating it simply because of my food being in direct contact with it and accumulating any chemicals from it at molecular levels that I have no lab access to check for.

    So here’s what I do instead without being able to completely relinquish the conveniences of modern life (yes, I’ve seen some sites out there such as ‘My Plastic Free Life’ but honestly I don’t want to be nutty about this) starting with plain old PVC plastic wrap: Foods are wrapped in wax paper and then an outer wrapping of plastic wrap (wax paper does not remain secure enough to seal in moisture and keep mold and bacteria out for a few days storage in the refrigerator.) Glass containers used for food storage that are used for lunch at work are either put into an old tupperware container to protect the glass or, if they won’t fit one of the old tupperware containers they go into a small padded tote and I use glass or glass lined bottles or stainless steel thermos containers for the hot beverages.

    Also, I’m slowly but surely phasing out the purchase of over the counter yoghurts that are all stored in plastic containers which the yoghurt went into and was exposed to heat (any we both know what that does to plastic:yep, speeds up the release of the proprietary blend of toxics from the plastics. I bought a yoghurt maker from Williams Sonoma with glass containers to make the yoghurt in. Other convenience foods: TV dinners with plastic containers. I don’t know about the others that are in a simple box with some sort of shiny lining but I’m shying away from those as a ‘rare, once in a while’ for eating and will increase my ‘scratch cooking’ and self preparation of my own tv dinners.

    Until modern chemistry figures out a way to make plastic for cooking completely inert I know none of them will trade plastic for the glass they use to conduct accurate experiments and people like us will largely refrain from plastics in our pantries, kitchens and meals!

  • Debbie

    Other items we might not think of as plastics laden: cookware. Yep, plain old non-stick cookware has a coating of a type of plastic designed for cooking. Did you know the vapors from non-stick cookware heated at cooking temperatures is a very common cause of death to pet birds such as parrots? Many of these coatings go by fancy names beyond the original Teflon to those such as stonedine, excalibur, etc. Companies that want to create non stick cookware should create cookware with waffle textured pot bottoms such as better manufacturers like Kuhn-Rikon and others.

    If there is a way to find out all the chemicals used in proprietary non-stick coatings that eventually find their ways into our bodies without us seeing them I think consumers would demand better more traditional cookware. it wasn’t until a professional chef video showed me that the correct heat up of heavy duty stainless pots will prevent food from sticking-unfortunately, in home kitchens unless your burners are gas or able to deliver unwavering heat consistency effective cooking in stainless or other cookware without a non-stick coating can be problematic and so the manufaturers continue to offer it!

  • Connie

    The link you posted Jan 13 2013 regarding Tupperware brands, Tupperware sustainability is no longer active. I sold Tupperware for years and have a ton of rock-n-serve that I have used for yers. I lays thought it was the safest because of the tough material. In some of the other type containers the plastic begin to get pitted from microwave use. I even have some rock-n-serve that has never been used because I thought it was the best. I justified paying more for Tupperware because I thought it was safer than “cheap” plastic. Now what..

    • kim

      Hi Connie,

      Just say thanks to our lovely world of “this is great for you!” until we have to tell the truth, which we still won’t do unless we get sued.

      What to do? You an millions others…buy glass. Sorry. Tupperware has done a bang up job of marketing, that’s for sure.

      Go through the article again. In the indented paragraph I added the link back to Tupperware.

    I am really loving the theme/design of your weblog.
    Do you ever run into any internet browser compatibility issues?
    A few of my blog readers have complained about my site not operating correctly in Explorer but looks great in Firefox.
    Do you have any advice to help fix this problem?

    • kim

      Hi Beli,

      If I have browser problems I don’t know about them from my side. Yes, Internet Explorer isn’t 100% for a lot of blogs.

      Sorry, I don’t have advice on your blog problem! 🙂


  • Dianna

    By the way, you don’t have to buy all your glass containers. I’m now washing out the occasional glass containers other foods come in the reusing them. Just like grandma used to do, right/ conservative, economical and healthy 🙂

    • kim

      Absolutely, Dianna!

      I too grew up in a very conservative, thrifty and “don’t waste anything” home.

      My pantry shelves have numerous glass jars of all kinds, and BALL canning jars. They all work wonders.

      Keep up the great economical job! 🙂

  • Gene

    I ware a full face respirator nearly everyday for my job, I get some tightness in my chest while wearing the respirator and a funny taste on my tongue. The respirator is made mostly of rubber / plastic. I believe I’m having a reaction to the chemicals used in the respirator. I have looked on-line for a full face respirator that’s BPA free but not having any luck finding one. Do you have any advice.

    • kim

      Hi Gene,
      I really don’t know about this kind of issue. Have you checked with the company that makes it?
      Also, check with your local hospital or pharmacy to see if they have referrals. You can’t be the only one who’s ever had a problem with this.

      I hope you find a solutions,


  • Linda

    So now I’m really scared, I have Hypothyroidism and Celiac Disease. So I’m throwing out all my plastic, wondering what I’m going to do about buying water, my vitamins, frozen foods, etc. I checked the New Chapter vitamins, they said they were in glass bottles, but guess what, they’re made with wheat and soy? Did you know that the way we process soy in this country makes it Toxic? Great, not sure what to do now.

    • kim

      Hi Linda,

      I’m so sorry for you double whammy of Hypothyroidism and Celiac Disease. This happens to many, it’s called “Piggy Backing” health conditions.

      Yes, going to glass is the best way. But, if you need to buy water, and such, just don’t let it sit forever and especially not in heat/temperature changes, in plastic. You will or may buy products in plastic, you can then move them over to glass as I do.

      Yes, many vitamins are made with wheat and soy. Check and see if there are options always. Do your best.

      Yes, I do know that the way we process soy in this country makes it toxic. Sadly, the way we “process” about everything in our country is toxic!

  • Donna

    Is BPA factor an issue only when tupperware is heated?

    • kim

      Hi Donna,
      No, if plastic/containers are not BPA-free, meaning they are BPA active, the “leaching of BPA chemicals” happens to your food at all times. NEVER heat plastic/tupperware anyway.

      My good thoughts are with you,


  • Canan

    Hello all,

    I agree about the harm when plastic is heated or microwaved.

    I am in doubt wiht the harm when tupperware is used for storage. If I put my salad or cooked meal to a tupperware, do harmful chemicals merge to my food?

    Glass is also not good when cooking. When you cook with glass, heavy metals,iron merge to food. Doctors are saying this. It is good only for storage.


  • Nadine

    This is such great info, thank you – a family member was giving away vintage Tupperware tumblers and I took 4 because they’re cute and I thought they would be perfect for my 1 year-old who is starting to want to drink from cups (he can’t break these!) but then I got to thinking about the whole leaching chemicals thing when trying to figure out how to sterilize them… I read pre-1979 Tupperware is top-rack dishwasher safe, but I have no idea how old these are; any way to tell? I know certain items stop off-gassing after a certain period of time, is this similar for plastics? I’m starting to think there’s no way these are safe but trying to find some redeeming information, any thoughts?

  • MAS

    What about the safety of silicone bakeware?

    • kim

      I wish I could find some research on it! Not sure why there isn’t any.
      “All” seem to approve of it’s safety. It’s certainly awesome stuff!

  • sweta

    Hi Kim, Now i become aware of plastic food grade codes after I am lover of plastic coz of unbreakable and light to hold and carry. I use pearalset to store spices and now I found out these plastic jars are code no 1 PET so it is not safe to store food right. so I should change all plastic jars code 1 pete to code 5 PP right?

  • Dotty

    I’ve read that glass contains BPA as well.

    • kim

      Hi Dotty, unfortunately it’s an iffy issue. I can’t find solid research on it, yet enough that it might be true.
      Use stainless steel and porcelain when you can.
      I’ll still use glass over plastic!


  • Mary

    I’m glad to see that uve included the update about tupperware in canada and the usa being bpa free! 🙂 They r safe to microwave in and convenient but glass is always safest…as long as u make sure it’s lead free 😉

  • hi kim

    Hi, hope your doing well. So I recently bough the smart steamer from tupperware, you cook your chicken breast in the microwave in 8 minute’s. How safe is it?

    • kim

      2 answers:
      1) Check to see if it’s BPA free.
      2) don’t cook anything in a microwave. studies show it changes food on the molecular level and then affects your health and DNA.

  • Vinith Fernando

    Hi Mam,

    A bit confusing question ever in our family……..

    Can we use tupperware products for storing water as well as lunch.???

    • kim

      It’s your decision, but my answer is, you don’t – unless for food, the tupperware is the newest and BPA free.

      For water – don’t, use glass.!

  • Hskj

    Hi mam
    Am confused. Is tupperware is safe for baby or not ?means sippy cup and water bottle. What about stainless steel. Thanks in advance.

  • Pat

    I have two really old Tupperware that I put sugar in one and flour in the other and that’s all I use it for. Is it safe ?

  • kim

    Tupperware says they are making more BPA products. Make sure to check ALL products you buy that are plastic, need to be BPA.

  • kim

    Trash it! It’s not good for anyone if not BPA free. Sorry.

  • Mary

    So my old orange & brown gallon size tea pitchers from the 70-80’s has bpa n them? Never anything but tea n them. Thanks
