Health Benefits From Just 7 Days Of Less Plastic Exposure: The Simple

If you've been meaning to reduce plastic in your kitchen but keep putting it off because it feels too hard, we have some great news for you and it's backed by science!

You don't need to overhaul your entire kitchen. You don't need a perfect system. You just need to start in the kitchen with anything that touches your food. And according to new research, it can make a measurable difference in as little as seven days.

The Study That Changed Everything

In April 2026, ABC News reported on a new study examining the link between plastic food packaging and harmful body chemicals. The findings were striking: participants who switched away from plastic food storage (replacing containers, wraps, and packaging with non-plastic alternatives) saw a significant reduction in chemical levels in their bodies within one week.

Yep, one week! Not a year of discipline or a complete kitchen renovation. Just seven days of intentional change.

For those of us who've been quietly worried about what's leaching into our leftovers every time we microwave a plastic container, this is the green light we've been waiting for.

What Makes Plastic Food Containers So Concerning?

Plastic containers, even those labelled BPA-free, can contain a range of chemical compounds that migrate into food, particularly when heated. Microwaving plastic is one of the most significant ways these chemicals transfer into what we eat and drink.

Common culprits include phthalates (used to make plastic flexible) and bisphenols (used to harden plastic). These compounds are classified as endocrine disruptors, meaning they can interfere with hormonal function. Over time, repeated low-level exposure adds up.

The good news? Our bodies can begin clearing these chemicals fairly quickly once the source of exposure is removed. That's exactly what the research demonstrates and it's super motivating, right?

Why Stainless Steel Is An Alternative Worth Considering

Not all alternatives to plastic are created equal. Stainless steel, specifically food-grade 304 stainless steel, is widely regarded as one of the safest, most durable, and most practical materials for food storage.

Here's why it consistently comes out as a great alternative to plastic:

It doesn't leach. Stainless steel is non-reactive, meaning it won't transfer chemicals, flavours, or odours into your food, even with acidic foods like tomatoes or citrus.

Unlike plastic containers, these stainless steel bases are completely uncoated, meaning there are no internal linings or coatings that can wear away over time.

It's durable. A quality stainless steel container can last years, even decades, with proper care. That's a significant reduction in both plastic waste and ongoing cost.

It's lightweight. Despite its strength, 304 stainless steel is surprisingly light, easy to carry in a bag, easy to handle in the kitchen.

It's genuinely versatile. From fridge to lunchbox, from pantry to on-the-go, stainless steel works across every scenario that used to require plastic.

Introducing: Our New Rectangle Stainless Steel & Glass Containers

We've been working on these for a while, and we're genuinely excited to share them.

Our new Rectangle Stainless Steel & Glass Containers are made from 304 stainless steel bases paired with semi tempered soda lime glass and silicone lids. They're designed to simplify your daily routine while supporting a lower-plastic, lower-waste kitchen.

Available in two sizes:

2-Pack — ideal for getting started, meal prepping for one or two, or packing lunches
3-Pack — the full kitchen upgrade, covering more meals and more uses in one go

What makes them different:

Microwave-safe base (yes, really). Stainless steel and microwaves have historically not been friends but we've engineered these containers to be microwave-safe when the lid is removed. It's the kind of everyday convenience that makes the switch actually stick.

Why is it microwave safe?

These containers have been specifically engineered for microwave use using food-grade 304 stainless steel. Unlike thin metals, foil, or sharp-edged objects that can cause sparking, the containers feature:

Smooth, continuous surfaces
Rounded edges
Consistent material thickness

This design helps microwave energy distribute more evenly across the surface instead of concentrating in one spot.

They’ve also been tested for safe use in modern microwaves when used as directed:

Remove the lid before microwaving
Place the container in the centre of the turntable
Avoid contact with the microwave walls
Heat in short intervals and stir between cycles

Airtight air-vent lids. The silicone-sealed, air-vent lids keep produce and meal prep fresh for longer. No more sad, soggy leftovers.

Transparent glass lids. See what's inside at a glance. This tiny feature makes a surprising difference in reducing food waste, when you can see it, you actually eat it.

Stackable, nesting design. Dishwasher safe and designed to nest together, so they don't take over your entire cupboard.

Lightweight and long-lasting. Easy to handle in daily use, and built to go the distance.

An Important Note on Caring for Your Containers

Because these containers are microwave-safe specifically due to their construction integrity, it's important to treat them with care. If a container becomes dented or damaged, it should no longer be used in the microwave, the structural change can affect its safety for heating.

The good news: even if a container is no longer suitable for microwave use, it still has plenty of life left in it. It can continue to be used for:

Lunches and on-the-go meals
Fridge and freezer storage
Meal prep
Pantry organisation
Oven use (container only, no lid)

It’s a simple way to extend the life of the product and support a lower-waste kitchen.

Using Containers Safely

Like any kitchen product, proper use matters.

To get the best performance from your containers:

Always remove the lid before microwaving
Place the container in the centre of the microwave turntable
Ensure the container does not touch the microwave walls
Heat in intervals of up to 2 minutes and stir between cycles
Do not microwave multiple metal containers or metal items together
Stop immediately if you notice sparking

Because stainless steel transfers heat efficiently, the container itself may become hot during use. Use a cloth or oven mitt when handling after heating.

Your 7-Day Plastic Reduction Plan

Inspired by the research? Here's a practical way to make the switch without overwhelm:

Day 1–2: Audit your current containers. Pull out anything cracked, stained, or warped, these are the ones most likely to be leaching.

Day 3: Replace your most-used plastic containers with your new stainless steel set. Start with whatever you use for leftovers or meal prep.

Day 4–5: Stop microwaving in plastic entirely. If you need to heat something, transfer it first.

Day 6: Check your pantry. Are there plastic containers storing dry goods that could be swapped out?

Day 7: Reflect. Seven days of intentional choices. The research suggests your body is already noticing.

Good luck on your plastic reduction quest!!!

Frequently Asked Questions

Will the container get hot?

Yes. Stainless steel transfers heat efficiently, so the container will become hot during use. Always handle with care and use a cloth, tea towel or oven mitt when removing it from the microwave.

What happens if the container is dented, scratched or damaged?

If the container becomes significantly dented, deeply scratched, cracked or misshapen, it should no longer be used in the microwave.

Damage can create uneven surfaces, which may affect how microwave energy distributes across the container. This can increase the risk of sparking or inconsistent heating.

However, the container can still be safely used for:
* Lunchware 
* Fridge and freezer storage 
* Meal prep 
* Pantry storage 
* Oven use (container only)

How do I avoid scratching the container?

Do not cut food directly inside the container 
Avoid sharp utensils 
Use soft sponges or cloths for cleaning 
Do not use abrasive scrubbers or steel wool

Scratches won’t affect general use, but deep scratches may impact microwave performance.

What happens with different microwave settings (e.g. defrost)?

Lower power settings such as defrost are safe to use and may provide more even, gradual heating.

Higher power settings (up to 1000W) can also be used, but it is recommended to heat in short intervals and stir food between cycles.

Can the container be used in the oven?

Yes. The stainless steel container is oven safe. Do not use the lid in the oven.

Can the container be used in the freezer?

Yes. The container is suitable for freezer use. When freezing liquids, leave room for expansion to prevent pressure build-up.

How should I clean the container?

Wash with warm, soapy water or place in the dishwasher 
Dry thoroughly after cleaning 
Avoid bleach, chlorine-based cleaners or abrasive materials

Does the container have a coating?

No. The container is made from uncoated 304 stainless steel. This means there are no internal linings or coatings that can wear away over time.

What type of glass are the lids made from?

Semi tempered soda lime glass which is partially strengthened, offering durability while maintaining flexibility.

What happens if the container is too close to the side of the microwave?

If the container is placed too close to the side, microwave energy may concentrate unevenly. This can lead to:

Uneven heating 
Localised hot spots 
Potential surface marks

 Always position the container in the centre of the turntable.

What happens if the container touches the microwave walls?

If the container touches the microwave walls or other metal surfaces, it may cause sparking (arcing).

This happens because metal reflects microwave energy, which can build up and discharge as sparks.

Always ensure there is space around the container during use.

How long should I microwave the container?

Heat in intervals of up to 2 minutes, then stir and repeat if needed.

Stainless steel does not heat in the same way as glass or plastic, so heating may take slightly longer overall.

Will food heat differently in stainless steel?

Yes. Stainless steel may heat food more gradually compared to glass or plastic because it reflects some microwave energy.

For best results:

Heat in shorter intervals 
Stir between cycles

Why is only one container recommended at a time?

Using multiple containers or additional metal objects can interfere with how microwave energy moves inside the appliance, increasing the risk of uneven heating or sparking.

Why can’t I use other metal items at the same time (e.g. cutlery or foil)?

Additional metal items can create multiple points where energy reflects and concentrates, increasing the likelihood of sparking.

Is stainless steel safer than plastic in the microwave?

Many people choose stainless steel to reduce plastic use. Some research suggests heating plastic can release microplastics or chemicals into food.

Stainless steel offers a durable, reusable alternative when designed for microwave use.

What damage can be caused if a dented container sparks in the microwave?

If a dented or damaged container is used in the microwave, it can create areas where microwave energy concentrates unevenly. This may lead to sparking (also called arcing).

Sparking can cause several types of damage:

1. Damage to the container

Burn marks or discolouration on the stainless steel 
Pitting or small surface imperfections 
Further weakening of already damaged areas

2. Damage to the microwave

Scorching or burn marks on the interior walls 
Damage to the microwave’s internal components over time 
In severe cases, it may affect the performance or lifespan of the appliance

3. Risk to food and safety

Uneven heating of food 
Localised overheating or hot spots 
In rare cases, sparks can pose a fire risk if left unchecked

What should I do if I see sparks?

Stop the microwave immediately 
Check that the container is not damaged 
Ensure it is not touching the sides or other metal

How can I tell if my container is microwave safe?

These containers are clearly marked on the base of the container as microwave safe.
Always check for this marking before placing any stainless steel container in the microwave.

Important: Not all stainless steel containers are microwave safe.  Do not confuse these with other stainless steel containers that are not specifically designed or labelled for microwave use.

If a container is not labelled as microwave safe, it should not be used in the microwave.

Can I use acidic foods in the stainless steel container?

Yes, acidic foods such as tomato-based dishes, citrus, or dressings can be used in the container.

304 stainless steel is highly resistant to corrosion and is suitable for everyday use with a wide range of foods, including acidic ingredients.

However, over time, highly acidic or oily foods may cause:
