“How much plastic will you have for dinner, sir? And you, ma’am?” While that may seem like a line from a satirical skit on Saturday Night Live, research is showing it’s much too close to reality.

Ninety percent of animal and vegetable protein samples tested positive for microplastics, teeny polymer fragments that can range from less than 0.2 inch (5 millimeters) down to 1/25,000th of an inch (1 micrometer), according to a February 2024 study. Anything smaller than 1 micrometer is a nanoplastic that must be measured in billionths of a meter.

Even vegetarians can’t escape, according to a 2021 study. If the plastic is small enough, fruits and vegetables can absorb microplastics through their root systems and transfer those chemical bits to the plant’s stems, leaves, seeds and fruit.

Salt can be packed with plastic. A 2023 study found coarse Himalayan pink salt mined from the ground had the most microplastics, followed by black salt and marine salt. Sugar is also “an important route of human exposure to these micropollutants,” according to a 2022 study.

Even tea bags, many of which are made of plastic, can release enormous amounts of plastic. Researchers at McGill University in Quebec, Canada found brewing a single plastic teabag released about 11.6 billion microplastic and 3.1 billion nanoplastic particles into the water.

Rice is also a culprit. A University of Queensland study found that for every 100 grams (1/2 cup) of rice people eat, they consume three to four milligrams of plastic — the number jumps to 13 milligrams per serving for instant rice. (You can reduce plastic contamination by up to 40% by washing rice, researchers said. That also helps reduce arsenic, which can be high in rice.)

Let’s not forget bottled water. One liter of water — the equivalent of two standard-size bottled waters — contained an average of 240,000 plastic particles from seven types of plastics, including nanoplastics, according to a March 2024 study.

Dangers to human health

While microplastics have been found in the human lung, maternal and fetal placental tissues, human breast milk and human blood, until recently there was very little research on how these polymers affect the body’s organs and functions.

A March 2024 study found people with microplastics or nanoplastics in arteries in the neck were twice as likely to have a heart attack, stroke or die from any cause over the next three years than people who had none.

Nanoplastics are the most worrisome type of plastic pollution for human health, experts say. That’s because the minuscule particles can invade individual cells and tissues in major organs, potentially interrupting cellular processes and depositing endocrine-disrupting chemicals such as bisphenols, phthalates, flame retardants, per- and polyfluorinated substances, or PFAS, and heavy metals.

“All of those chemicals are used in the manufacturing of plastic, so if a plastic makes its way into us, it’s carrying those chemicals with it,” Sherri “Sam” Mason, director of sustainability at Penn State Behrend in Erie, Pennsylvania, told CNN in a prior interview.

“And because the temperature of the body is higher than the outside, those chemicals are going to migrate out of that plastic and end up in our body,” Mason said.

“Those chemicals can be carried to your liver and your kidney and your brain and even make their way across the placental boundary and end up in an unborn child,” she said.

 

“There currently is no scientific consensus on the potential health impacts of nano- and microplastic particles. Therefore, media reports based on assumptions and conjecture do nothing more than unnecessarily scare the public,” a spokesperson for the International Bottled Water Association, an industry association, told CNN previously.

All types of proteins contained microplastics

In the February study, which was published in Environmental Research, researchers looked at over a dozen commonly consumed proteins, including beef, breaded and other types of shrimp, chicken breasts and nuggets, pork, seafood, tofu and several plant-based meat alternatives, such as nuggets, plant crumbles similar to ground beef and plant-based fish sticks.

Breaded shrimp contained the most tiny plastics by far, at well over an average of 300 microplastic pieces per serving. Plant-based nuggets came in second, at under 100 pieces per serving, followed by chicken nuggets, pollock fish sticks, minimally processed White Gulf shrimp, fresh caught Key West pink shrimp and a plant-based fish-like stick.

The least contaminated proteins were chicken breasts, followed by pork loin chops and tofu.

After comparing the results to consumer consumption data, researchers estimated the average exposure of American adults to microplastics could range between 11,000 and 29,000 particles a year, with a maximum estimated exposure of 3.8 million microplastics per year.

Fruits and vegetables tested high in plastics

The oceans are filled with plastics, and a number of studies have captured how those are ending up in the seafood we eat. However, fewer studies have looked at vegetables and land animal proteins, such as cattle and hogs, according to an August 2020 study.

The study, published in Environmental Science, found between 52,050 and 233,000 plastic particles under 10 micrometers — each micrometer is about the diameter of a rain drop — in a variety of fruits and vegetables.

Apples and carrots were the most contaminated fruit and vegetable, respectively, with over 100,000 microplastics per gram. The smallest particles were found in carrots, while the largest pieces of plastic were found in lettuce, which was also the least contaminated vegetable.

Plastics are everywhere

There are a staggering number of plastics in the world, today, according to a recent analysis — 16,000 plastic chemicals, with at least 4,200 of those considered to be “highly hazardous” to human health and the environment.

As these chemicals break down in the environment, they can turn into microplastics and then nanoplastics, particles so small science struggled for decades to see them.

A recent study that utilized brand new technology found the number of nanoplastics in three popular brands of water sold in the United States to be in between 110,000 and 370,000 per liter, if not higher. A liter is the equivalent of about two 16 ounce bottled waters. (The authors declined to mention which brands of bottled water they studied.)

Prior research using older technology had identified only about 300 nanoplastics in bottled water, along with bigger microplastics.

Ways to reduce plastic

The levels of contamination found in bottled water reinforce long-held expert advice to drink tap water from glass or stainless steel containers to reduce exposure, Mason said. That advice extends to other foods and drinks packaged in plastic as well, she added.

“People don’t think of plastics as shedding but they do,” she said. “In almost the same way we’re constantly shedding skin cells, plastics are constantly shedding little bits that break off, such as when you open that plastic container for your store-bought salad or a cheese that’s wrapped in plastic.”

While science learns more about the plastics we consume, there are things people can do to reduce their exposure, according to experts.

· Try to avoid eating anything that has been stored in a plastic container. Look for food stored in glass, enamel or foil.

· Wear clothing made from natural fabrics and buy consumer products made from natural materials.

· Don’t microwave in plastic. Instead, heat food on the stove or by microwaving in glass.

· If you can, eat as much fresh food as possible, and limit purchase of processed and ultraprocessed foods wrapped in plastic.

Since Dr Ken Berry did a video about this a week or so ago and went through my closet to lose some of the polyester clothing. I have made an efforts to carry water in metal for years but still have plastic bottled water on hand for my husband's lunches. I think we are over hydrating most of the time. Even doing those things plastic is unavoidable in daily life. I wonder if we would be having these problems if DuPont didn't suppress the use of hemp in the 30's

I can't escape plastic. Sure, I use wood cutting boards, drink from glass or stainless steel, store food in glass containers (with plastic snap on lids), at home. But I also buy meat in bulk and separate it into plastic quart freezer bags, and when you eat out, all your food and beverages (especially fast food) get served in plastic.

I've always hated polyester. I do love me some rayon though, lol.

Wow! Just WOW! I had no idea the magnitude of it all.
I saw that same video with Dr. Berry and decided to start cutting out as much plastic as I can but it’s just impossible. I still plan on getting wood cutting boards and only using glassware and silverware but all of my storage containers, while most of them are glass, still have plastic lids. All of my stainless steel tumblers and thermoses have plastic lids. The inside of my refrigerator is mostly plastic. It’s just too overwhelming. I’ll try but I’m afraid it’s an exercise in futility.

I do prefer the glass storage containers, but man are they a pain to store. Its hard to nest glass containers inside each other without chips eventually happening. I did purchase glass quart pitchers with lids to store iced tea in. I found one of them in a really cool hardware store in a small town that had a bit of everything.  The other one I got at Walmart and it looks like a wine carafe they have at restaurants.

Slightly off topic: Specifically bottled drinking water and its containers

They already charge too much for good water. If they repackage good bottled water in glass it will raise the prices even more. Metal tends to impart an undesirable flavoring to water. I did a blind test and picked my preferred source accurately. I am sensitive to water sources. My throat closes up and my mouth puckers when drinking water from certain sources. I can taste the petroleum in the milky plastic bottles. 

I found a suitable source and exclusively drank that water for years. I don't know whether they changed their process at the same time but coinciding with a change in the bottle shape and strength of the plastic the water tasted different. It was bitter when it was the only water that was nearly flavorless. It was enough that I stayed up for two days driving in every possible direction to every known store which carried it to buy up the remaining inventory of the water using the old bottles. I had water stored in every space I could fit it. I had to walk around stacks in open spaces. I eventually ran out and had to adjust to the taste of the new container.

Years later I found a 6-pack of the old stock I had overlooked. It was now 10+ years old. They do stamp and expiration date on their bottles. It was years beyond that date but I tasted it anyway. It was superior as I remembered it. Of course I finished off that 6-pack. I used to find it during once per year sales for a significantly discounted price. I would do a sale run buying several month's worth but not as thoroughly as when they changed the bottle. Then the distributor changed and prices kept going up. Now locally it is only when desperate that I pay their outrageous prices. The consistently lowest source has been online. But that can vary from month to month as much as $10 per 6-pack. I noticed recently that the source tells me how many times I have ordered it. I have ordered 1-3 12-packs 64 times since switching to online purchases amounting to quite a large sum of money for drinking water. I recall drinking off the garden hose when I was a kid.

When it comes to drinking water on the go I just bring my own in metal containers.

I have a PUR filter at home that I use. I also have an OPAL ice cube maker that makes the tiny little ice pellets. If I take water to go, I have a 32oz thermos with a metal lining. It doesn't seem to effect taste for me, at least not to any degree that bothers me.

I will drink out of water bottles if I have to. At the music festival Saturday, they would throw cold water bottles into the crowd. I caught a few of those and drank from them all day.
