The Truth about Aluminium Foil

As a health-conscious person, I'm always looking for ways to make my lifestyle more sustainable and environmentally-friendly.


When it comes to aluminium foil, I think it's time we consider the potential risks it poses to both our health and the environment.



Aluminium foil is a convenient and reliable way to store food, but it can be a health hazard.

When heated, aluminium foil can leach into your food, potentially leading to health complications.

Studies have shown that the aluminium can trigger an increase in the production of free radicals in the body, which can damage cells and lead to inflammation.


In the long-term, this can increase the risk of developing diseases such as cancer. Aluminium foil is also damaging to the environment. It is made from a non-renewable resource, and is not biodegradable or recyclable.


This means that when it's disposed of, it ends up in landfills and can take hundreds of years to break down. The production of aluminium foil also contributes to air and water pollution. Overall, while aluminium foil is a convenient way to store food, there are potential risks to our health and the environment that we should be aware of.


If you're looking for a more sustainable way to store food, I recommend the following alternatives:


Beeswax Food Wraps


Beeswax wraps are a great alternative to aluminum foil. They’re made of beeswax, cotton, and tree resin and work like a charm to keep food fresh.

Simply wrap your food container in the beeswax wrap and scrunch it secure. They’re also great for lining containers to be used and sandwich or picnic boxes.

You can use the wraps repeatedly (just give them a quick hand wash with cold water and eco friendly dish soap), and they’ll quickly biodegrade on your compost heap when they reach the end of their usable life.


Cedar Wraps


Made from sustainable cedar wood, cedar wraps are excellent alternatives to aluminum foil when cooking outside on the grill.

Simply wet the wraps and wrap them around the meat/fish/veggies you’re cooking.

Not only do they protect wherever you’re cooking from getting too charred, but they also give the food a subtle smoky flavor. Win-Win!

Cedar wraps are not reusable but can be cut up and tossed onto your backyard compost heap.


Silicone Lids


If you use aluminum foil to cover food storage bowls and containers full of leftovers destined for the fridge or freezer, then maybe give reusable silicone lids a try. They’re fantastic alternatives to aluminum foil.

Silicone is non-toxic (when approved by the FDA and marked as ’food safe’ or ’food grade’), durable, and dishwasher safe. You can reuse them for many years.

Silicone lids come in different sizes and can cover various items, such as cans, cups, bowls, dishes, and plates.


Glass Containers


Another great option for leftover food storage is glass containers. Alternatives to aluminum foil don’t come much better than this tried and trusted choice.

They’re odorless, don’t stain like plastic containers, and can stack, so they won’t take up much space in your fridge or freezer.


They come in various sizes and are dishwasher safe.

Another advantage of storing food in glass is that you can quickly see what food is within. This helps to avoid the accumulation of uneaten food and reduce food waste.


Most glass containers come with BPA-free plastic snap lids. Or you can use the silicone stretch lids mentioned above.


Silicone Baking Sheets


A silicone baking sheet is an excellent option if you’re looking for a greener way to line and protect your baking.

They’re made of non-toxic silicone and can be reused over and over. Plus, they’re dishwasher safe, so they’re easy to keep clean.


Make sure you buy silicone baking mats approved by the FDA and made with high-quality food-safe silicone. Cheap, unregulated silicone baking sheets might leach chemicals into your food. Not good!


Also, on the subject of leaching, be sure to read the manufacturer’s instructions and don’t use them in an oven hotter than the recommended temperature (usually around 250 degrees Celsius).




Parchment Paper


Parchment paper is a good alternative for lining baking pans and protecting countertops when rolling out dough. But it’s far from perfect!


Unbleached and untreated parchment paper is good because it’s a natural product that can usually be composted once all food deposits have been removed.


However, many parchment papers have been treated with chemicals to aid their non-stick and heat-resistant properties. These often cannot be composted.


Also, parchment paper is usually only good for a single use.


So, some parchment papers are better than aluminum foil, but there are better options.


Fabric Food Covers


Fabric food covers are a great way to keep food fresh and free from pests without resorting to aluminum foil.

You can make your own fabric food covers from old tea towels or organic cotton t-shirts, for example, or buy them online. They come in all sizes and shapes, so you’re sure to find one that fits the food storage solution you’re trying to cover.



Simply cover the bowl, plate, dish, etc., with the fabric and secure it with string or a rubber band.

Fabric food covers can be machine washed and reused over and over again. They’ll last for years!
