8 Everyday Foods That Contain Plastic and Safe Alternatives

9 foods that contain plastic

Is this food healthy? This is a question that crosses many peoples mind when shopping. You can’t just rely on the ingredients in the packet as many contain harmful ingredients like microplastics that aren’t listed.

Our lifestyles are polluting the worlds water supplies and this is feeding back into the food chain. With sharing this knowledge we can make choices to reduce the amount of plastic we eat and put pressure on changing things for the better.

While there is limited research as to what the long-term effect of ingesting plastic is, it’s highly unlikely to be good news as limited lab results have shown negative impacts on health.

Here is a list of common everyday foods that contain plastic:

microplastics in tea bags

Tea Bags

Did you know that as of 2018 over 95% of tea bags contain plastic? Plastic is used in the sealing for most tea bags.

If a teabag has a crimped edge or seal it will contain plastic. Manufacturers claim it’s just a small amount but this makes teabags undesirable to compost as they will leave behind microplastics and a brew can contain microplastics.

Avoid microplastics in tea by either using loose tea leaves or by choosing a brand that has folded edges and is sealed with a string and or staple.

tinned tomato contains microplastic

Tinned Foods

Most cans in 2018 are lined with BPA, the plastic chemical that has been linked to cancer, obesity and other serious health conditions. This plastic leaches into the contents of the food and is a source of microplastics in the average person’s diet.

The worst food in cans is acidic produce like tomatoes as the high PH value increases the number of plastics and chemicals leached into the food. Instead of buying tined tomatoes try getting tomatoes or passata in jars. Tinned tomatoes are handy but I’ve stopped buying them due to the serious effects of BPA.

A pressure cooker is a worthwhile investment to cook your own fresh pulses and beans from dried. If you cook them at home you can change the water; making them less gassy. Freeze in batches so they are just as handy as tins. This also cuts down on the environmental cost of creating and transporting heavy tins.

microplastics are floating in your home

Floating in Your Home

Lots of the dust in your home could be plastic floating around that has come from clothes, furnishings and industrial processes. Microplastics can be airborne and are often floating around homes. This easily ends up landing on food and is another significant source of plastic we are eating.

Avoid microplastic in your home by only wearing natural fibres, air your house regularly (if away from factories in a clean area) and clean often. If you are bad at cleaning it might be worthwhile getting a robotic hoover. Modern robo vacs are good at cleaning everywhere and get into corners.

micro plastics- n water bottles

Plastic Bottles

Most bottled water is sold in disposable plastic bottles. These leach microplastic and other chemicals into the water. Bottled water is often sitting in plastic for months and filled just after the plastic bottle is created and is off-gassing chemicals.

A plastic bottle sat in direct sunlight will deposit even more microplastics. Tests have shown that bottled water has twice the amount of microplastic fibres in it compared with tap water – up to 10’000 plastic pieces per litre.

If you have to buy bottled water try to get a brand that is bottled in glass. Although even with a glass water bottle that there might be plastic in the lid, but it will be significantly less compared to a plastic bottle.

Never reuse a single use plastic bottle as they are unstable and will leach even more plastic into your water. Invest in a good quality glass or metal bottle that will last for many years.

Try to have filtered tap water (if it’s safe where you are) or harvest water from a spring if you can.

Ready Meals and Food Packaging

Most ready meals are served in plastic packaging as of 2018. This potentially leaches microplastics both into the food during manufacturing and when the plastic containers are microwaved/oven baked.

If you have to have ready meals then try to get ones in cardboard (some manufacturers are moving away from plastic) and heat in a glass or ceramic container. Some cardboard containers could still be lined in plastic.

Most take away cups contain plastic in the lid and a layer of polyethene. This can leach into the beverage and will break down into fragments of microplastic when disposed of. Use your own takeaway cup made from a compostable material like bamboo.

Juice containers and plastic soup containers also leach microplastic into the contents. Another reason why it’s better to make your own. All of the Nest and Glow Recipes are healthy and easy to do, many have a prep time of less than 10 minutes.

microplastic in salt


As seas are gradually getting polluted with microplastics it’s no surprise that sea salt is often contaminated. Studies have shown that 1KG of sea salt can contain over 600 microplastics.

Even normal table salt contains microplastics as a recent study showed that 36 of the 39 brands tested contained microplastics. However, the amount did vary significantly with salts in Asia and in particular Indonesia being significantly higher in plastic fibres. Indonesia has some of the worst water plastic pollution levels in the world.

To avoid microplastics in salt choose a high-quality brand of rock salt that was formed before the world was polluted. Pink Himalayan rock salt is said to have been formed 800 million years ago so will be free of plastic as long as you choose a high-quality brand that hasn’t been adulterated.

microplastics in beer


There have been several studies on US beer and German beer that both found microplastics in the final beverage. The source of these microplastics is attributed to the water supply as they used municipal water and had similar amounts in a pint of beer as you would expect in a pint of tap water.

To avoid this try to find a beer that is brewed using either filtered water or a water supply that is known to be low in contaminants.


A study of 19 different types of honey from Europe and South America concluded that all contained plastic fibres. The amount of plastic in honey varied from 45 to 600 plastic particulates per 1 KG.

As Nest and Glow is a vegan site I don’t recommend anyone has honey from an ethical view as bees are exploited in the process. Instead how about making your own date syrup to replace honey? It’s healthier as it contains all the fibre from the fruit.

Fish and Seafood

The oceans now contain a significant amount of microplastics that are invisible to the human eye. This plastic has been found in just about all fish and seafood. Fish have been shown to mistake plastic for food and accidentally eat it.

Although lots of the microplastic in fish doesn’t get ingested, as the stomach and gut of fish isn’t eaten, there’re still traces throughout the whole animal. Eating fish and particular muscles is a big source of microplastics.

The Bottom Line

  • The biggest causes of microplastics are usually seafood, bottled drinks and food packaging.
  • Microplastics floating around your home can land on food and be eaten.
  • Simple steps to reduce microplastic include changing brands of salt and tea bags.
  • Avoiding plastic packaging is an effective way to reduce plastic in the environment and the food supply.
  • Long-term effects of microplastics in our diet are unknown but test tube studies suggest it’s harmful.
  • It’s best to minimise the amount of plastic in our diet while ongoing studies are carried out.

  1. Great information! Thank you so much! I had no idea I was ingesting that much plastic, not to mention that it is associated with obesity! Yikes! That could explain the weight epidemic in the U.S. since convenience foods are wrapped, packaged, or bottled in plastic shelling along with the high fat, sodium, and sugars that comes with it. I hope more people will follow a vegan healthful diet and lifestyle, and heed the advice given on this site!

    1. Hi Suzette, great to see you on the site! Glad you found it useful – plastic in the food supply is such an issue, the long-term effects aren’t known but it can’t be good for us or the planet. Hopefully, a couple of these tips will help people reduce their exposure to plastics. Have a great week!

  2. Interesting and heart breaking to see the amount of plastic scattered over beaches and floating around in the sea as I’ve lived on 3 continents in the past 7 months.
    The cost of healthy foods, compared to junk/convenience food does not come cheap. For those who are living on a low income and who have children, it is way out of their weekly price range and this needs to change.
    Easy to see why those less fortunate have weight issues and eat junk food.
    Junk food is nearly all packaged in plastic, often multiple layers, always on special offer and in abundance in all 3 continents. Sad times we are living in ????

  3. Thank you so much the information was well taken. I think the recipe is just delicious. I used dates to sweetened my smoothies but never made a syrup out of it. This I will do for sure.

    1. Thanks so much Ronda, glad you liked this article and my recipes. Do let me know how you get on with them – I use date syrup all the time these days.

  4. Creating awareness is th way forward. Good on you Bastian.
    Love your recipes.
    A new syrup I’ve just tried is Carob syrup…awesome….

    1. Oh yum! Did you make it or buy it? I do love how naturally sweet carob is, just chewing on the pods is tasty – have to watch out for the seeds though.

  5. Is there a website that posts alternatives to the almond milk containers- they are always in plastic or the carton is certainly lined this way.

    1. Bastian Durward

      It’s difficult as that so many different brands worldwide. All the ones in the UK i’ve seen come in plastic bottles or plastic lined foil cartons so I just make my own. I’ve seen some small places do in house raw almond milk in glass, but very expensive and not avalible to many. I would just blend some water with almond butter to make your own almond milk and save all that packaging and expensive transportation of water. Hope that helps

  6. I like your article and it sounds very much logical and alarming. However, I do miss references to (scientific) literature which makes it difficult for me to believe everything that you write. It would be great to cite your sources so people can verify that what you write is indeed correct!

    1. Bastian Durward

      Hi there, I do link to scientific studies if available, sometimes there isn’t due to the nature. Was there any one in particular you were concerned with?

  7. Very interesting and informative. I’ve just watched this subject being discussed on TV and was shocked to read about Yorkshire t bags. I’ll be changing to loose leaf tea forthwith, investing in a water filter jug and buying less tinned foods. It’s pretty frightening what is happening to our planet and our food chain.

    1. Thanks so much, yes it’s my only book. Honestly it took me so long to do it all myself so will be a while before another one comes out.
