Individuals within the US eat between an estimated 39,000 and 52,000 microplastic particles yearly. This could come from objects in our kitchens, takeout containers and even the meals we eat. Nonetheless, sure meals are extra probably than others to comprise microplastics. To study extra about which meals we should always control, how microplastics have an effect on our well being and methods to keep away from them, we consulted a household doctor and did our analysis.

What number of microplastics are too many?
“There isn’t any formally established ‘protected’ or ‘unsafe’ stage of microplastic consumption. It is smart to need your publicity to be as little as doable,” Dr. Joseph Mercola, a board-certified household drugs osteopathic doctor, mentioned in an e-mail.
Microplastics can enter our meals due to contamination the place the meals was grown, raised or processed. Mercola defined that utilizing plastic mulch and plastic seed coatings in agriculture, and irrigation with contaminated water, are among the many numerous methods microplastics can find yourself in meals. Plastic packaging, utensils and containers are extra sources.
In response to the US Meals and Drug Administration, present proof does not imply that the degrees of microplastics in meals are a danger to us. Nonetheless, you continue to may wish to reduce how a lot microplastics you passively eat. These are the most typical meals that comprise microplastics, and the measures you may undertake to cut back your plastic consumption.
High 8 meals in your eating regimen that comprise microplastics
1. Seafood
Probably the most vital methods plastic particles find yourself in our meals is thru single-use plastics that break down and discover their approach into waterways and soil. After they attain the oceans, they find yourself in our seafood.
“Microplastics are then taken up by plankton and mistaken for meals by fish and shellfish,” Mercola mentioned. “The tiny particles accumulate within the flesh … then find yourself on our plates.”
A current research printed by Portland State College found quite a lot of microplastics in 180 out of 182 examined seafood samples. Microfibers are the most typical sort of microplastic current, however this is not the one sort that leads to our oceans.
The way to keep away from it: When you cannot management what number of microplastics your fish ate earlier than it bought to your plate, you may scale back the quantity of filter feeders and backside feeders you select to eat (e.g., clams, mussels, oysters, catfish, halibut, flounder and cod). These kind of seafood are uncovered to larger quantities of microplastics. Additionally, select seafood on the retailer that makes use of sustainable packaging, not plastic wrap.
2. Tea baggage
Polypropylene is usually used to make tea baggage, and even in the event you select paper tea baggage, they will nonetheless comprise microplastics. The difficulty is that when the luggage contact scorching water, microplastics could also be launched into your tea.
Researchers on the Autonomous College of Barcelona found that polypropylene tea baggage can launch plastic particles within the billions, and nylon and cellulose tea baggage can launch them within the thousands and thousands.
The way to keep away from it: You do not have to cease consuming tea. Swap to loose-leaf tea and spend money on a stainless-steel diffuser to take pleasure in your tea freed from microplastics.
3. Rice
Rice can also be a hotspot for microplastics. A College of Queensland research discovered that for each half cup of rice, there are 3 to 4 milligrams of plastic. In case you use instantaneous rice packets, that quantity is 4 instances larger, at 13 milligrams.
The way to keep away from it: The research discovered that washing your rice can scale back plastic contamination by 20% to 40%, although it is price noting that the research used filtered water for rinsing.
4. Salt and sugar
While you high off your dinner with a sprinkling of salt, you are getting an unintentional aspect of microplastics. It is laborious to outrun salt. It is in virtually all the pieces we eat and our our bodies want a specific amount of sodium to maintain our fluids and electrolytes balanced.
One research discovered that 90% of the 39 sampled salt manufacturers worldwide contained microplastics. This probably outcomes from environmental contamination and the manufacturing and packaging course of, which incorporates plastic. Microplastics have additionally been present in sugar.
The way to keep away from it: To scale back your publicity to microplastics in your salt and sugar, you should purchase them packaged in glass or cardboard.
5. Bottled water
Bottled water is without doubt one of the most well-known sources of micro and nanoplastics. One research estimated that there are about 240,000 plastic particulates in a liter of bottled water. Most pliable water bottles you purchase on the retailer are constituted of polyethylene terephthalate, or PET, plastic, so it wasn’t stunning to see it represented. Plastic particles break aside when bottles are squeezed or uncovered to warmth. And PET plastic is not the one sort of nanoplastic researchers have discovered in plastic water bottles.
The way to keep away from it: Consuming faucet water from a stainless-steel or glass container can scale back your danger of ingesting plastic particles.
6. Honey
You won’t count on your honey to harbor microplastics, but it surely does, even when it is in a glass jar. Microplastic fibers will be traced again to bees and air pollution. One research exploring whether or not microplastics ingested or carried by honeybees have been then integrated into hives discovered that bees can proceed the dispersal of microplastics by way of honey.
The way to keep away from it: Shopping for honey from native beekeepers who typically use extra pure and sustainable harvesting strategies might scale back the danger of microplastic contamination.
7. Fruits and veggies
Greens and fruits are a vital a part of a balanced eating regimen. They’ll additionally comprise microplastics. One research that sampled fruit and greens discovered that apples have been probably the most contaminated fruit and carrots have been probably the most contaminated vegetable. How does this occur?
“Crops have been proven to uptake micro- and nanoplastics from soil by way of their root techniques, contaminating the edible parts,” Mercola mentioned.
Many grocery shops additionally package deal fruit and greens in plastic to maintain them contemporary. In response to the FDA, there is not sufficient proof to find out that microplastics from plastic meals packaging migrate into meals. However Mercola suggests you keep away from it as a lot as you may anyway.
The way to keep away from it: Wash your fruit completely, peel when doable and select native or natural produce.
8. Proteins
A current research from researchers on the Ocean Conservancy discovered that 88% of vegetable and animal proteins comprise some stage of microplastics. However extremely processed proteins, like plant-based options, fish sticks or rooster nuggets, harbor probably the most microplastics, suggesting the microplastic contamination partly comes from meals processing. The research discovered that breaded shrimp had a mean of 300 microplastic items per serving. Plant-based nuggets had 100 items per serving.
Meals processing is not the one approach microplastics can get into these protein sources. Microplastics are in animal feeds and within the environments the place animals are raised. Plant-based options will be contaminated by way of the soil or irrigation.
The way to keep away from it: After studying that, it’s possible you’ll marvel what protein you need to eat. The fact is that extra analysis is required to know the precise ranges and their influence on our well being. Our our bodies want protein to perform, so getting sufficient is essential, no matter your chosen supply.
What do microplastics in meals imply for you?
So, do all meals comprise microplastics? I am unable to say for certain. I can let you know, nonetheless, that extra analysis is required to grasp simply how consuming meals with microplastics impacts us. Nonetheless, though the long-term well being results stay beneath investigation, microplastics are one thing to be careful for and guard towards in the event you can, as Mercola defined.
“Ingested microplastics have been discovered to build up within the circulatory system and numerous organs, together with the mind, the place they will trigger irritation and tissue harm,” Mercola mentioned.
Different potential negative effects are hormonal imbalances attributable to the endocrine-disrupting chemical substances present in plastics. Microplastics may take in different environmental toxins and introduce them into the physique.
There isn’t any established protected stage of microplastics and we will not fully outrun them: They’re all over the place and in all the pieces. But it surely’s a good suggestion to reduce publicity the place you may.
Skilled ideas for decreasing your consumption of microplastics
You possibly can lower down by following this recommendation:
1. Watch out how a lot shellfish you eat
Shellfish like mussels, oysters and scallops have larger ranges of microplastics, so do not overdo it.
2. Keep away from food-storage containers fabricated from plastic
That is one in all Mercola’s largest strategies due to the “plasticizing chemical substances” in plastic. BPA and phthalates are endocrine-disrupting chemical substances that may switch from plastic to meals. They’re fat-soluble, so this occurs most simply with fatty meals. It is best to retailer meals with fats in glass containers, however you may retailer dry meals in plastic if it’s worthwhile to.
3. Keep away from plastic-wrapped meals
This may be simpler mentioned than performed but it surely’s one thing to try for in areas the place you may swap.
4. Eliminate plastic kitchen utensils
From the spoons we use to stir our sauces to the chopping boards we use to cut our greens, in the event that they’re plastic, you are ingesting microplastics. A superb rule of thumb is: Something plastic that is available in contact along with your meals needs to be swapped out for ceramic, glass, stainless-steel or wooden.
To assist deal with the general difficulty of microplastics, you may set up a filter in your clothes-washing machine. In case you can afford it, a particular filter will catch microfibers earlier than they pollute water techniques. The PlanetCare 2.0 microfiber filter begins at $125.
We nonetheless have loads to study microplastics and their long-term implications for our well being when ingested. It could be laborious to listen to they’re in so a lot of our meals however that should not deter you from consuming properly. A balanced eating regimen of protein, fruit and greens will guarantee your physique has sufficient gasoline to perform and thrive — microplastics or not.
Is there a water filter that removes microplastics?
Whereas there may be all kinds of water filters in the marketplace, Lifestraw is without doubt one of the few manufacturers that targets microplastics in consuming water. The model claims that its membrane microfilter removes 99.999% of microplastics in addition to properly as micro organism and parasites. In case you’re in search of a water filter that may take away microplastics, search for water filter pitchers and bottles that particularly point out microplastics or select a whole-home water filtration system.
