The Food & Drink Items That Contains Microplastic

microplastic in food and drink items

Did you know that some food items contain microplastic? Worryingly, here are eight key food and drink items that have been found to contain microplastic.

Nobody would willingly chow down on a bowlful of plastic. However, over the past few years, scientists have horrifyingly been finding microplastic in some of the most common food that we eat and the beverages that we drink. In fact, one study estimates that we each could be consuming as much as 5 grams of plastic a week. That’s the equivalent weight of a credit card. Over the course of a year, that’s 52 credit cards. Yikes!

Firstly, What Is Microplastic And Where Does It Come From?

Before looking at which foodstuffs contain microplastic, let’s first understand what microplastic is, and where it comes from.

Microplastics are what we call fragments of any type of plastic less than 5 mm in length. Sometimes these are visible to the human eye, other times they are so small that they cannot be seen.

Microplastics come from a variety of sources. Some microplastics are produced for commercial use, such as the cosmetics industry. Microbeads are banned. Yet other cosmetics like makeup and sunscreen (yes, sunscreen contains microplastic) are permitted to contain microplastic.

Other microplastics result from the breakdown of larger plastic items. These include plastic water bottles, plastic bags, and other items made of plastic. Microplastics are also shed from synthetic clothing when washed, and other textiles, such as fishing nets. Car tyres are also a major source of ocean microplastics. Meanwhile, paint flaking off of marine vessels is also a source. In short, there’s no single source, which makes it difficult to turn off the tap when it comes to microplastic.

Microplastics enter our food chain when they enter our oceans and waterways, and enter our soil. When microplastics are in the food we eat and that water we drink, this means we are ingesting plastic. The long-term effects of consuming plastic are not yet fully understood by scientists. However, microplastics have found in the placentas of unborn babies, in human faeces, and in our organs, such as our lungs, liver, spleen, and kidneys.

The Food That Contains Microplastic

Now we know more about microplastic, here are the food and drink items that scientists have found to contain microplastic.

Fruit & Vegetables

Italian researchers found microplastic in fruit and vegetables. Apples and carrots have the highest levels of microplastic particles. However, microplastics appeared in other crops such as pears, broccoli, lettuce, potatoes, radishes, and turnips.

Contamination in fruit and vegetables is thought to occur when plants suck water that contains microplastics up through their roots. The microplastic pass into the shoots, and form the edible parts of the plants. Fruit is more highly contaminated than vegetables. This is because fruit trees are older with deeper, more established root systems, and so they take in more water compared to vegetables.

Salt

Would you like some microplastic on your chips? Yup, research has found microplastics in 90% of table salt brands sampled from across the globe. This means that even if the food you eat doesn’t contain microplastic, then what you season it with probably does. The bad news is that microplastic in salt isn’t geographically isolated to one part of the world. Therefore it’s impossible to find a salt that doesn’t contain microplastic. Sea salt has the highest concentration of microplastic, followed by lake salt and then rock salt.

Tea

Microplastics aren’t just found in the food we eat, but also in the beverages we drink. Tea, for example, contains microplastic. This is because teabags are heat-sealed using polypropylene plastic, to stop tea bags from breaking. Other brands use plastic mesh tea temples in place of paper-based tea bags. The good news is that some brands have started to phase out the use of plastic in their teabags. Check out my post on plastic-free teabags for an updated list for 2021.

Bottled Water

If you’re thinking sod tea, I’ll just stick to water, then I’ve got bad news. Tap water contains microplastic. If this news makes you want to pass on tap water, then the bad news is that bottled water contains even more microplastic. In fact, researchers found that bottled water contains roughly twice as many plastic particles compared to tap water. And it was also found that the single largest source of plastic ingestion globally is through water, both bottled and tap.

It’s not entirely clear why bottled water is more contaminated. It could be contaminated source water. However, it is more likely that it has come from the plastic polymers used to make the bottles and bottle caps.

Reach for the tap – it’s better all round.

Beer

Bad news, beer lovers. In 2020, scientists found microplastic in beer. The study looked at a variety of beverages. Whilst microplastics were found in most of the beverages studied, beer was found to have the highest levels of microplastics.

Whilst the average number of particles found in beer was similar to the average number of particles found in tap water, water supply isn’t always a factor. Another study found that two beers brewed in the same city using the same municipal water supply had wildly different microplastic levels. This suggests the beer production process may also generate microplastics.

Rice

Fancy a side of plastic with your curry? A 2021 study found that microplastic is found in packaged rice. Regardless of whether the rice was packaged in paper or plastic, the type of packaging made no difference. And worryingly, pre-cooked rice (such as sachets of microwavable rice) contains four times as much plastic. The takeaway here is to try to avoid instant rice, and instead cook your own.

The researchers tried a number of methods to see if they could reduce the concentration of microplastic in rice. They found that shaking the rice in its packaging made no difference in the concentration of plastics. However, they did hit top tip gold. Washing your rice before cooking reduces plastic contamination by 20 to 40%.

Fish & Shellfish

Unsurprisingly, samples of fish and shellfish contain microplastic. Zoologists believe that this has come from fish ingesting microplastics found in water or on the seafloor, or by ingesting prey that have previously ingested microplastics themselves. Commercially farmed fish are also likely to be fed fishmeal that inadvertently contains microplastic.

Not all seafood is equal though. Since microplastics usually start out in an animal’s gut, seafood which includes the animal’s stomach, like mussels, oysters, shrimp, prawns, and other filter-feeding sea life, may be more likely to contain higher levels of microplastic.

Honey

I think the most worrying find on my microplastic and food research mission was finding out that honey contains microplastic.

Bees are the most infinitely complex and fascinating creatures. The bodies and legs of bees are covered in thousands of tiny hairs. When bees are in flight, these tiny hairs become positively charged. This is partly because of the friction of the air against the bee. When a positively charged bee lands on a flower, it attracts the negatively charged pollen grains. These grains then naturally stick to the bees’ hair.

It’s a whole world of wonder. And you’re probably wondering where the microplastic comes into play? Well, it’s not just pollen that the tiny hairs on bees collect and hold. These positively charged hairs also attract other matter. Traditionally this would have been bits of plant matter or dust, but it seems that bees are now also attracting airborne plastic. This plastic gets taken back to the hive, and consequently ends up in honey.

Where or who you buy your honey from seems to have little impact on the concentration of microplastic in each jar. One team of Danish scientists studied bees from hives located in different settings. Some hives were located in a city, and other hives were located in suburban and rural areas. It was anticipated that the bees located in urban areas would present the highest counts of microplastics. This is because urban areas contain the highest densities of microplastics. And indeed, the city bees did have the highest counts of microplastics. However, the surprising find was that the counts of microplastics on suburban and rural bees were not much lower. This highlights the role of wind in dispersing microplastics.  

So What To Do About Microplastic In Food?

The probability is that microplastic is in the vast majority of the food that we eat and the things we drink. What’s more, it’s also in the air that we breathe. A study at Macquarie University in Sydney took samples of airborne dust from homes, where it was found that 40% of it was plastic. There’s simply no way to avoid microplastic.

Microplastic is a global problem that we as individuals alone can’t solve. What’s more, there isn’t one single solution to eliminating microplastic from the food we eat. Scientific American says that according to microplastic experts, in order to get a handle on our microplastic problem, the world needs to take three primary steps.

In the short term society needs to significantly curtail unnecessary single-use plastic items such as water bottles, plastic shopping bags, straws, and utensils. In the medium term, governments need to strengthen garbage collection and recycling systems to prevent waste from leaking into the environment between the trash can and the landfill and to improve recycling rates. And in the long run, scientists need to devise ways to break plastic down into its most basic units, which can be rebuilt into new plastics or other materials.”

I would add a fourth primary step. That is that corporations need to reconsider their packaging and consider alternatives away from throwaway plastics as a matter of urgency. The worst plastic polluters include Coca-Cola, PepsiCo, Nestle, Danone, Proctor & Gamble, Unilever, and Colgate-Palmolive. These companies have a huge responsibility to curtail their plastic packaging and plastic usage.

Where Do We Begin?

In the interim, I think that instead of asking whether it is dangerous to eat apples or drink water or beer that contains microplastics, we should instead use this knowledge as a conversation starter. Discussing, as a society – including consumers, governments, scientists, and manufacturers – just how and when we should use various types of plastic materials feels like a good way forward. As a society, we can and must do better, and finding ways to turn the tap off on microplastics is imperative.

Eco-Friendly Sunscreen Guide for 2022

eco-friendly sunscreen guide

 Today I am sharing my guide to eco-friendly sunscreen, updated for 2022.

I’m all about eco-friendly beauty products.  From sustainable soap to plastic-free conditioner and to zero-waste makeup, I always think that the best products are ones that work well, are effective, affordable, and are made sustainably.  The sunscreen market should be no different.

Questions have been raised about the ingredients in conventional sunscreen.  Whilst in the past, more sustainable options have been limited, in 2022 the market for sustainable sunscreen has grown hugely.

What To Look For In An Eco-Friendly Sunscreen

Unfortunately, even in the eco-friendly market, not all sunscreens are equal.  Be wary of brands that say they offer “complete protection” without any further detail.  Instead, look for ones that specifically say that they give broad-spectrum protection.  Specifically both UVA and UVB protection.

Also, be wary of sunscreens saying they offer protection above Sun Protection Factor (SPF) 50.  There is no evidence anything above SPF 50 offers increased protection.  This also fools you into thinking you can reapply less.  Be mindful that you still have to reapply the cream every couple of hours regardless of the SPF.

Guide to Eco-Friendly Sunscreen

eco-friendly sunscreen guide

To help you through this minefield I’ve done some research.  As such, I’ve come up with a few reliable eco-friendly sunscreen brands – from vegan-friendly to reef-safe options, and more.  Each offers a good SPF.  And all creams featured also offer both UVA and UVB protection and are safe for all of the family to use.

This post contains affiliate links, denoted by a *.

Badger SPF 30 Sunscreen

Badger Sunscreen* is one of the best eco-friendly sunscreens on the market.  It offers an SPF of 30 and provides protection from both UVA and UVB rays.  It’s 100% harsh chemical-free.  What’s more, it contains 87% certified organic ingredients and is hypoallergenic.  This makes it safe for every member of the family, even little ones.

If you’re planning on snorkeling or diving in coral reefs or other environmentally sensitive ecosystems, then it’s a great choice.  As it’s completely biodegradable it won’t cause any harm to the reefs or waterways.  And for the final thumbs-up, it’s not tested on animals.  However, do bear in mind that it’s not vegan as it contains beeswax.

The downside is that it is not readily available in the UK.  However, I’ve tracked down this one, and other sunscreens in their range, on Amazon*.

Green People SPF 30 Eco-Friendly Sunscreen

Green People’s* 78% certified organic eco-friendly sunscreen packs great protection from UVA and UVB rays.  It’s also free from parabens, alcohol, Lanolin, phthalates, artificial perfumes, petrochemicals, and colourants.

Green People’s sunscreen is suitable for the most sensitive of skin, even babies, and rubs in really well.  It’s not vegan, however, due to the inclusion of beeswax. 

 Green People have also confirmed that it is reef-safe, so good news if you are planning on diving or snorkelling.  

Available with free delivery from Green People for £25.50* for 200 ml.  This is a great family size for holidays.  Also, take 10% off your first order when you sign up for the Green People newsletter.

Jāsön Sun Family Sunscreen SPF 45

Free from parabens and SLS, the Jāsön eco-friendly sunscreen offers a hefty SPF45 protection from both UVA and UVB rays.  It’s also gentle and non-irritant, making it great for all of the family.   The sunscreen is not tested on animals and is vegan-friendly, however, if you are planning on snorkeling then bear in mind it’s not reef-safe.   If you’re after a reef-safe sunscreen then try the Jāsön Mineral SPF30 sunblock*, which is £14.99, from Look Fantastic.

Jāsön Sun Family Sunscreen is available from Ethical Superstore for £12.99* for 113 g, making it a handy size for carrying around in your bag.  

Sol De Ibiza Sunscreen

If you are looking for plastic-free sunscreen, then try Sol De Ibiza*. This SPF 50 natural sunscreen, which protects you from both UVA and UVB rays, gives you great protection without any plastic packaging. This fragrance-free, non-nano formulation is made with organic and cruelty-free ingredients and is suitable for the whole family. What’s more, it’s water-resistant and reef-safe.

At £23 for 100 g, it is not the cheapest product. However, I tried this out over the hottest days of summer and found it to offer mighty eco-friendly sun protection.

Sol De Ibiza also comes in cardboard pushup tube* for easier application on the go. Ironically, I found it difficult to apply the sunscreen in the tube as the texture is more akin to that of a wax crayon. This means it’s tricky to get any on your skin. My advice? Stick with the tin.

Odylique Natural Sunscreen

This exceptionally pure, 100% natural, eco-friendly sunscreen was the first sun lotion to be accredited as both Fairtrade and organic.  What’s more, it’s also cruelty-free and certified vegan.

The sunscreen itself is great for very sensitive skin, including babies and children.  The mineral zinc oxide is the active ingredient, delivered in non-nano format.  As such, it offers broad-spectrum UVA and SPF30 UVB protection.

Odylique’s formulation protects the skin whilst actively caring for it.  This is through its mixture of nine organic botanicals.  These include Fairtrade raw shea butter, which replenishes and soothes skin.  The formulation also contains a mixture of chamomile, rosemary, and sea buckthorn to calm sun-sensitive skin.  

The light, non-greasy formula makes for easy application and for immediate protection.  Find it here* at Big Green Smile.  Prices start from £15 for a 50ml tube.

Weleda SPF 30 Sunscreen

Weleda’s SPF 30 Sunscreen* offers waterproof UVA and UVB sun protection with natural non-nano mineral UV filters.

This high-factor natural and vegan sunscreen does leave a white sheen on your skin.  However, this is due to its non-nano mineral UV filters, which reflect harmful UV rays.  In terms of skincare, organic virgin coconut oil and shea butter protect the moisture level in young skins. 

The fragrance-free formula is also clinically tested.  As such, it’s suitable for sensitive skins – both babies and adults.

All ingredients are grown biodynamically by Weleda.  Where this isn’t possible, ingredients are ethically sourced from around the world.  

Find it on sale at Content Beauty*.
