Microplastics used to sound like a distant environmental problem, however they’re exhibiting up in additional locations than you’d anticipate, together with the meals we eat every single day. Based on new analysis, even one thing so simple as chewing gum may very well be exposing you to tiny plastic particles.
With one thing as frequent as chewing gum changing into a supply system for microplastics, many individuals are involved about how typically they’re consuming the potential hidden hazard. The common particular person takes in between 39,000 and 52,000 microplastic particles annually simply from foods and drinks. That quantity is extra like 120,000 in the event you embrace airborne particles.
To raised perceive how microplastics might have an effect on your well being, we talked with a household doctor. We mentioned what is taken into account a “secure” stage of microplastic consumption, which meals have the best content material and what you are able to do proper now to scale back your publicity.

What number of microplastics are too many?
“There isn’t a formally established ‘secure’ or ‘unsafe’ stage of microplastic consumption. It is sensible to need your publicity to be as little as potential,” Dr. Joseph Mercola, a board-certified household drugs osteopathic doctor, stated in an e mail.
Microplastics can enter our meals attributable 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 varied methods microplastics can find yourself in meals. Plastic packaging, utensils and containers are further sources.
Based on the US Meals and Drug Administration, present proof doesn’t mean that the degrees of microplastics in meals are a danger to us. Nonetheless, you continue to may need to decrease how a lot microplastics you passively eat. These are the most typical meals that include microplastics, and the measures you possibly can undertake to scale back your plastic consumption.
Prime 8 meals in your food regimen that include microplastics
1. Seafood
One of the crucial important methods plastic particles find yourself in our meals is thru single-use plastics that break down and discover their manner 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 stated. “The tiny particles accumulate within the flesh … then find yourself on our plates.”
A current research revealed 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 results in our oceans.
keep away from it: When you cannot management what number of microplastics your fish ate earlier than it received to your plate, you possibly can cut 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 go for seafood on the retailer that makes use of sustainable packaging, not plastic wrap.
2. Tea baggage
A plastic known as polypropylene is usually used to make tea baggage, and even in the event you select paper tea baggage, there can nonetheless be microplastics in them. The difficulty is that when the baggage contact sizzling 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.
keep away from it: You do not have to cease ingesting tea. Swap to loose-leaf tea and put money into a stainless-steel diffuser to take pleasure in your tea freed from microplastics.
3. Rice
Rice can be a sizzling spot 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 occasions larger, at 13 milligrams.
keep away from it: The research discovered that washing your rice can cut back plastic contamination by 20% to 40%, although it is price noting that the research used filtered water for rinsing.
4. Salt and sugar
Once you high off your dinner with a sprinkling of salt, you are getting an unintentional aspect of microplastics. It is arduous to outrun salt. It is in nearly every little thing we eat, and our our bodies want a certain quantity of sodium to maintain our fluids and electrolytes balanced.
One research discovered that 90% of the 39 sampled salt manufacturers worldwide contained microplastics. This possible outcomes from environmental contamination and the manufacturing and packaging course of, which incorporates plastic. Microplastics have additionally been present in sugar.
keep away from it: To cut back your publicity to microplastics in your salt and sugar, you should buy them packaged in glass or cardboard.
5. Bottled water
Bottled water is among 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 moldable water bottles you purchase on the retailer are made out of polyethylene terephthalate, or PET, plastic, so it wasn’t shocking 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.
keep away from it: Ingesting faucet water from a stainless-steel or glass container can cut back your danger of ingesting plastic particles.
6. Honey
You won’t anticipate your honey to harbor microplastics, but it surely does, even when it is in a glass jar. Microplastic fibers may be traced again to bees and air pollution. One research exploring whether or not microplastics ingested or carried by honeybees have been then included into hives discovered that bees can proceed the dispersal of microplastics by means of honey.
keep away from it: Shopping for honey from native beekeepers who typically use extra pure and sustainable harvesting strategies might cut back the danger of microplastic contamination.
7. Fruits and veggies
Greens and fruits are a vital a part of a balanced food regimen. They’ll additionally include microplastics. One research that sampled fruit and greens discovered that apples have been essentially the most contaminated fruit and carrots have been essentially the most contaminated vegetable. How does this occur?
“Vegetation have been proven to uptake micro- and nanoplastics from soil by means of their root programs, thereby contaminating the edible parts,” Mercola stated.
Many grocery shops additionally package deal fruit and greens in plastic to maintain them recent. Based on 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 possibly can anyway.
keep away from it: Wash your fruit completely, peel when potential and go for native or natural produce.
8. Proteins
A current research from researchers on the Ocean Conservancy discovered that 88% of vegetable and animal proteins include some stage of microplastics. However extremely processed proteins, like plant-based alternate options, fish sticks or hen nuggets, harbor essentially 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 manner microplastics can get into these protein sources. Microplastics are in animal feeds and within the environments the place animals are raised. Plant-based alternate options may be contaminated by means of the soil or irrigation.
keep away from it: After studying that, you could be questioning what protein you need to eat. The fact is that extra analysis is required to know the precise ranges and their affect on our well being. Our our bodies want protein to operate, so getting sufficient is necessary, irrespective of which supply you select.

What do microplastics in meals imply for you?
So, do all meals include microplastics? I can not say for positive. I can let you know, nevertheless, that extra analysis is required to grasp simply how consuming meals with microplastics impacts us. Nonetheless, although the long-term well being results stay below investigation, microplastics are one thing to be careful for and guard in opposition to in the event you can, as Mercola defined.
“Ingested microplastics have been discovered to build up within the circulatory system and varied organs, together with the mind, the place they’ll trigger irritation and tissue harm,” stated Mercola.
Different potential unintended effects are hormonal imbalances brought on by the endocrine-disrupting chemical compounds present in plastics. Microplastics also can take in different environmental toxins and introduce them into the physique.
There isn’t any established secure stage of microplastics, and we won’t utterly outrun them: They’re in all places and in every little thing. But it surely’s a good suggestion to attenuate publicity the place you possibly can.
Professional suggestions for lowering your consumption of microplastics
You may minimize 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 considered one of Mercola’s largest options due to the “plasticizing chemical compounds” in plastic. BPA and phthalates are endocrine-disrupting chemical compounds 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 possibly can retailer dry meals in plastic if it’s good to.
3. Keep away from plastic-wrapped meals
This may be simpler stated than performed, but it surely’s one thing to try for in areas the place you possibly can change.
4. Eliminate plastic kitchen utensils
From the spoons we use to stir our sauces to the slicing 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 together with your meals must be swapped out for ceramic, glass, stainless-steel or wooden.
To assist tackle the general problem of microplastics in meals, you possibly can 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 programs. The PlanetCare 2.0 microfiber filter begins at $125.
We nonetheless have rather a lot to find out about microplastics and their long-term implications for our well being when ingested. It may be arduous to listen to they’re in so a lot of our meals, however that should not deter you from consuming properly. A balanced food regimen of protein, fruit and greens will guarantee your physique has sufficient gasoline to operate and thrive — microplastics or not.
