Do you remember the era of Tupperware parties? A seemingly strange thing, people were floored by inventor Earl Tupper’s Poly-T products that infiltrated shops, department stores and people’s homes where small groups were given product demonstrations and could place orders following the party.
It was the type of plastic no one knew they needed. Durable, air-tight, and without the smell of plastic many had despised in products past, Tupperware became the go-to storage containers. But things have changed.
While efficiency makes our ears perk up, the constant health concerns associated with many products in today’s society have us searching for healthier alternatives. More and more research has proven that plastic leaches chemicals into our foods and drinks, which can wreak havoc on our health.
In this article, we will discuss the common concerns associated with the plastics used in Tupperware, unfold the research linking it to health issues, and provide you with the best alternatives to store your food and drinks.
What Plastic Is Used in Tupperware?
A common plastic used in Tupperware and other plastic storage containers is Bisphenol A (BPA). It’s also used in epoxy resins, often found in the lining of aluminum cans, metal lids, and in the resin of some forms of shiny paper. BPA is a known endocrine disrupting chemical, and because BPA leaches from these products and makes its way into the human body, serious concern has been raised about avoiding it at all costs.
Approximately 1,000 animal studies have been conducted on BPA, with the majority finding a link between this plastic and a variety of health problems including increased risk of cancers, cardiovascular problems, impaired brain development, infertility and more.
A study conducted on humans in 2010 found that adults who had the highest amounts of BPA in their urine were more than twice as likely than those with the lowest levels to contract coronary heart disease (1).
And a review of research on BPA published in the journal Environmental Health Perspectives, noted that, in both animal models and in women, ovarian toxicity is one of the most consistent and strongest effects discovered (2).
In March of 2010, it was announced that items sold by Tupperware US & CA are BPA free. And many other brands have followed due to the increasing amount of threats associated with it. But just because something is BPA free doesn’t make it the right choice. In fact, many companies have turned to another type of plastic in their storage containers, and it may be even more toxic for you.
BOTTOM LINE: DESPITE THE INITIAL POPULARITY OF TUPPERWARE AS THE GO-TO STORAGE CONTAINER FOR FOODS AND DRINKS, THIS NAME BRAND, AND OTHER CHEAP KNOCK-OFFS, HAVE A HISTORY OF USING A TOXIC CHEMICAL, BPA, WHICH STUDIES HAVE LINKED TO SERIOUS HEALTH CONCERNS.
What Is The Common Replacement for BPA In Tupperware?
Bisphenol S (BPS), is often used in storage containers instead of BPA, but it may be even worse for your health.
Studies show that it’s now found in 81% of blood tested (3), and that it can lead to ailments such as diabetes, obesity, asthma, birth defects and cancer. These companies have essentially found a loophole in the issue of safe plastic by replacing one endocrine disruptor for another.
A study conducted in 2013 by researchers at the University of Texas Medical Branch found that, even when BPS was present in minute concentrations, it has the ability to disrupt cellular function (4).
Even though the facts are in front of you — the risks exposed — you may still be hesitant to throw out your plastic containers out of bewilderment as to how they can make their way into your system and affect you. But it happens much easier than you may think.
BOTTOM LINE: COMPANIES FOUND A WAY AROUND PEOPLE’S DISDAIN FOR BPA BY USING ANOTHER TOXIC PLASTIC, BPS. MANY CONSUMERS LOOK FOR BPA FREE CONTAINERS NOT KNOWING THIS VERY FACT. ULTIMATELY, THIS EXPOSED THE REALIZATION THAT NO PLASTIC IS SAFE.
How Do These Toxic Plastics Get Into The Body?
BPA and BPS make their way into the body primarily through diet. While there are many ways they can come in contact with you, including through air, dust and water, it is their ability to leach into the foods and drinks being stored in these containers that is the biggest problem.
For example, they leach into Tupperware, engulfing the foods and drinks being stored, which you then consume. There have been many recommendations claiming that the older your plastic container is, the worse off it is for you, but it’s more than just that. It’s how you use them, too.
Let’s say you put hot soup in a Tupperware container. The warmer the temperature, the easier it is to essentially allow the chemicals in the plastic to release into the soup. Research has discovered that, when both new and used polycarbonate drinking bottles (made with BPA) were exposed to boiling hot water, BPA was liberated from them 55 times quicker (5).
Many people are also guilty of placing their Tupperware in the microwave. No matter what a product says about being microwave tolerant, anything plastic should never go into this contraption. Not only do some run the risk of melting in the microwave, but they increase the rate at which the toxic chemicals in them are released, leaving you drinking or eating some very scary stuff.
But it’s not just BPA and BPS that might be releasing from these containers.
BOTTOM LINE: IT’S NOT ENOUGH TO THROW OUT YOUR PLASTIC WHEN IT’S GETTING OLD. EVEN BRAND NEW TUPPERWARE CONTAINERS CAN RELEASE BPA OR BPS. FURTHERMORE, YOU EXPOSE YOURSELF TO EVEN MORE RISK WHEN YOU USE THESE PLASTIC CONTAINERS IN THE MICROWAVE, OR PUT WARM LIQUIDS IN THEM. YOU’RE BETTER OFF USING HEALTHIER ALTERNATIVES AND GETTING RID OF YOUR PLASTIC CONTAINERS ALTOGETHER.
What’s The Other Problematic Chemical In Plastic?
It’s becoming more and more apparent that just because Tupperware and other plastic containers try to market themselves as being toxic free, they’re simply beating around the bush that plastic is detrimental to our health.
There have been numerous tests conducted on hundreds of plastic products put through real-life situations, including heating foods in them in the microwave, that have found the presence of estrogenic chemicals (6). In the tests, these chemicals seeped out of 95 percent of the plastic products.
Deborah Kurrasch, a lead researcher of a study conducted on the effects of both bisphenol A and S on the brain development of zebrafrish, weighed in on the matter, saying, “A lot of the alternative chemicals have not been adequately tested because they don’t have to be… A compound is considered safe [by the FDA] until proven otherwise.”
While plastic is proving to be a poor form of storage for our health, what about the way it affects our planet?
BOTTOM LINE: NOT ONLY CAN YOUR PLASTIC CONTAINER EXPOSE YOU TO THE RISKS OF BPA AND BPS, BUT RESEARCH HAS ALSO DISCOVERED THE PRESENCE OF ESTROGENIC CHEMICALS.
What’s The Environmental Harm?
Along with BPA and BPS posing a variety of health threats, they’re also unkind to the environment as well. And if you’re working on becoming greener for your health and your planet, you’ll want to avoid Tupperware at all costs.
From shampoo bottles to house cleaning containers, yogurt packaging to water bottles, plastic is probably taking up some serious real estate in your home already. Honing in on your food and drink storage containers, you might realize you’re using all plastic. Plastic is made from petroleum, which is a fossil fuel that released toxins and greenhouse gases into the environment, contributing to climate change.
The Natural Resources Defense Council (NRDC) estimates that the plastic industry emits 14 percent (7) of the most destructive toxic industrial releases. It can be hard to give up something that is lightweight, cheap and dependable, but there are far better alternatives you should be using instead.
BOTTOM LINE: PLASTIC CONTAINERS AREN’T JUST BAD FOR YOUR HEALTH, THEY’RE BAD FOR THE ENVIRONMENT, TOO, AS THEY RELEASE TOXINS AND GREENHOUSE GASES. IT’S CLEAR THAT THE BAD OUTWEIGHS THE GOOD IN TERMS OF STORING YOUR FOOD IN PLASTIC.
What Are The Best Alternatives To Tupperware?
Food storage containers made of glass, metal and/or rubber are your best bet. Weck jars, for instance, are made of all three, are known to seal up well, and function great when put in the refrigerator, pantry or on the go.
Canning jars are another great option. They come in a variety of sizes, seal well, and you won’t have to worry about chemicals leaching, flavors transferring, or discoloration. A big trend is putting salads in these types of jars for life on the go, since the dressing doesn’t have to be stored separately when placed at the bottom, as it keeps from sogging the ingredients. All you have to do is shake the jar when you’re ready to eat, and everything gets evenly mixed up for you to consume right out of the jar.
People are also taking advantage of stainless steel tiffins, which even big stores like Walmart and Target now carry.

Take the quiz above and see if you got the correct answer!
In April, 2009, researchers stunned the medical community when they reported chronic inflammation as the root cause of several major diseases.
See, every year 610,000 people in the U.S. die of heart disease. Cancer claims another 584,000...stroke 130,000...Alzheimer's disease nearly 85,000 — and the list goes on.
Truth is, we now know... chronic inflammation is responsible for 7 out of the top 10 leading causes of death in the United States! Hundreds of studies and scientific reviews prove it.
Fortunately, newer research shows you can prevent-even reverse-most major diseases by "turning off" inflammation. And in our new book, we show you how to do just that.
If you or a loved one is suffering from a debilitating condition-and you"re not sure what the culprit is-now's the time to find out...while you can still do something about it!
