Can non-toxic food storage containers boost your food’s health? Consider this…

Whenever you toss leftovers in a plastic food storage container, you get more out than you put in.

In other words, your food sucks in plastic bits, which you eat with your leftovers.

Now, we discussed non-toxic dinnerware, non-toxic cookware, and even cleaning products in the past.

So it’s only fair to tackle Tupperware.

It’s a shame to serve food on safe dinner plates only to taint your leftovers with plastic storage containers.

So, in the hunt for a healthy lifestyle, non-toxic food storage containers have their place.

In this post, you’ll uncover the best healthy food containers. But first, there’s something you need to know about plastic…

“Safe” plastic containers have their share of pitfalls – seemingly innocent items with a splash of guilt.

But good news – there’s a way to audit your plastic’s risk. Before we get there, let’s answer the most common question first…

What Are the Dangers of Plastic Containers for Food?

Dangers of Plastic Containers

Chances are you own a cabinet full of plastic food storage containers. They’re convenient, sure, but misuse can leak unhealthy materials into your meal.

Manufacturers use several types of plastic to mold food storage containers.

Certain plastics are safer than others, but you never truly know. Even plastic, quoted as “safe,” grows concerning under stress.

What stress? The heat from hot food, microwaving, scratches, and sunlight.

And stressed plastic containers don’t unwind by the pool to relax.

Instead, plastic leaches out chemicals like Bisphenol A (BPA) and Phthalates.

BPA is a chemical used to harden polycarbonate plastics and epoxy resins.

Those leached chemicals migrate into your food. Then, inside your body when you eat lunch.

Plastic food storage containers and estrogen…

BPA is troubling because it causes Estrogenic Activity (EA)…

Simply put, BPA mimics the hormone estrogen in the body.

According to studies, EA chemicals link to adverse health effects on the heart and brain. Plus, child developmental problems.

Early childhood exposure to BPA links to ADHD behaviors – including inattention, hyperactivity, and depression.

And what about phthalates?

Phthalates are chemicals used to make plastics more flexible and harder to break. Like BPA, phthalates present their own share of concerns.

While the CDC claims phthalates show impacts on animal reproductive systems – more research is needed to fully understand human impacts.

My opinion?

Ditch the plastic containers regardless to keep any proven (or potential) hazard out of your food! Instead, grab one of the ten best non-toxic food containers below.

But hang on. Is ditching plastic difficult for you? Considering how vast container usage is.

If that’s your case, this next section is for you. We answer the question:

Are there any safe plastic food containers at all?

Are Any Plastic Food Containers Safe?

are-plastic-food-containers-safe

To answer the question, “are plastic food containers safe?” you need to know which kind of plastic you’re looking at.

So the short (and annoying) answer – it depends.

If you must use plastic containers, always check the recycling number.

Follow the steps below:

How to check for the best food-grade plastic containers (Avoiding BPA)

To audit your plastic container’s risk level, flip the product over and browse for numbers 1-7 surrounded by a triangle (made of 3 arrows). This is the recycling symbol (see image above.)

The safest plastic containers for food are numbers 1, 2, 4, and 5. These generally do not contain BPA.

Products with numbers 3, 6, and especially 7 most often contain BPA.

Items labeled number 7 and/or bear the marking “PC,” are polycarbonates. These plastics contain BPA to add “give” to the rigid plastics. This reduces cracks and breaking.

If a plastic product is rigid and transparent, odds are, it’s polycarbonate and contains BPA. For example, a clear, reusable food storage container.

Soft, flexible, and cloudy plastics are less likely to contain BPA.

The point is, always check the labeling.

Other BPA culprits

Since the 1950s, companies have used BPA in plastic. So, older plastic containers have BPA more often than new ones.

This is because less information was available on BPA’s dangerous side effects at the time.

Even worse, other old containers might not even have recycling numbers embossed onto them. Facepalm.

Plus, old plastic containers are often worn out too and, in turn, leach more chemicals into foods.

So, audit your cabinets. If you discover ancient plastic containers, chuck them.

Even for newer containers, check the recycling numbers listed above.

IF you’re going to use plastic containers, follow these guidelines…

  • Do not microwave or otherwise heat food in any plastic container.
  • Do not save or reuse commercial plastic food packaging. Single-use takeout containers, for example. These aren’t meant to reuse and will pollute your food with plastic.
  • Do not serve hot food in plastic food containers.
  • Do not wash these food containers in the dishwasher as the heat degrades the plastic.

The bottom line… If you must use plastic containers, check their number and follow these precautions.

But, if you’re able to buy new non-toxic food storage containers, that’s your best bet.

And if you’re not able to buy new, consider reusing glass mason jars leftover from pasta sauce!

What Are the Safest Food Storage Containers Made From?

Safest-Food-Storage-Containers-materials

With plastic out of the way, now we can discuss the safest food storage containers to keep your food free of toxins.

Generally, these reusable non-plastic food containers are the following…

Glass, stainless steel, silicone, or ceramic. All four are safe and non-toxic.

Sure, these materials are (a little) more expensive than plastic. But, their safety and durability make for a smarter investment.

Not just safer, but these materials have other unique benefits over plastic.

Before the next section, let’s tackle the pros and cons. This way, you better understand glass, stainless steel, silicone, and ceramic storage containers.

Then, you’ll find the best non-toxic food storage containers made from all four materials. An option for every purpose!

Glass Containers

Glass is an all-time favorite material for food storage containers. Thanks to its toxin-free, non-porous surface and versatility!

Most of the time, glass food storage containers are soda-lime glass. This glass is about 70% silica (aka, sand), 15% soda (sodium oxide), and the rest lime (calcium oxide).

Pros:

  • Plastic-free.
  • Toxin-free.
  • Microwave-safe.
  • Hot food-safe.
  • Refrigerator & freezer safe.
  • Dishwasher-safe.
  • Oven-safe (although lids made from different materials might not be).
  • Non-porous surface – easy to clean & doesn’t hide bacteria.
  • Recyclable.
  • Does not absorb food tastes or smells.
  • Non-reactive with acidic foods.

Cons:

  • Heavier than plastics – difficult to travel with.
  • Fragile – requires safe handling.
Stainless Steel Containers

Stainless steel food storage containers are rising in popularity by the minute.

Stainless steel’s corrosion resistance makes it a great non-toxic option for storing food. Steel is clean and non-porous, so bacteria have little chance to gather.

Stainless is unbreakable (child-proof) and lightweight – good for travel.

This metal is an alloy of iron, nickel, and chromium.

Pros:

  • Plastic-free.
  • Toxin-free.
  • Hot-food safe.
  • Refrigerator & freezer-safe.
  • Dishwasher-safe.
  • Oven-safe (although lids made from different materials might not be).
  • Non-porous surface – easy to clean & doesn’t hide bacteria
  • Recyclable.
  • Does not absorb food tastes or smells.
  • Unbreakable (Child-friendly).
  • Lightweight – great for travel.

Cons:

  • Not microwave-safe.
  • A little pricey.
  • Can sometimes give acidic foods a metallic taste.
Silicone Containers

Silicone food storage containers are another fantastic non-toxic option. You’ll notice silicone making its way into kitchens around the world. And for a good reason…

This revolutionary material shares plastic’s desired characteristics. Silicone is flexible, lightweight, and moldable (fun designs). Yet, it’s free of the negatives like BPA, phthalates, and other chemicals.

Silicone remains inert even past 400℉. Inert means it doesn’t change state (melt) or leach chemicals.

Plus, it’s unbreakable, soft, and super flexible. So, an excellent option for kids.

Silicone is made of silicon (sand), oxygen, carbon, and hydrogen.

Pros:

  • Plastic-free.
  • Toxin-free.
  • Silicone containers are microwave safe.
  • Hot food-safe.
  • Refrigerator & freezer-safe.
  • Dishwasher-safe.
  • Soft & flexible – great for children.
  • Oven-safe (although lids made from different materials might not be).
  • Unbreakable (Child-proof).
  • Lightweight & easy to travel with.
  • Recyclable.
  • Non-reactive with acidic foods.

Cons:

  • Low-quality silicone can contain chemical fillers.
  • Although recyclable, it’s hard to locate a recycling center able to process silicone.
  • Can sometimes absorb smells & tastes of food or soap.
Ceramic Containers

People have used ceramic for thousands of years in food storage and preparation. And for a good reason…

It’s a pure and natural material, made from shaped clay and baked in a high-temperature kiln.

Plus, ceramic is non-reactive with acidic foods and can withstand scorching heat.

Pros:

  • Plastic-free.
  • Toxin-free.
  • Microwave-safe.
  • Hot food-safe.
  • Refrigerator & freezer-safe.
  • Dishwasher-safe.
  • Oven-safe (although lids made from different materials might not be.
  • Does not absorb food tastes or smells.
  • Non-reactive with acidic foods.

Cons:

  • Heavy like glass – difficult to travel with.
  • Fragile  – requires safe handling

You can even store foods in the fridge or freezer then go right into the microwave or oven without worry. Bet you can’t do this with plastic Ziplocs!
