Microplastics are the newest hidden hazard fear for the world — and now they’ve even been present in chewing gum. UCLA researchers have discovered that each time we chew gum, microplastics are launched instantly into our mouths. Along with that, a new study revealed in Chemistry for Life examined 10 chewing gum manufacturers and located each single one contained microplastics. This was discovered to be the case with each pure and artificial varieties. A gram of gum releases round 100 microplastics on common, with some items spiking as excessive as 600.
With one thing as widespread as chewing gum turning into a supply mechanism for microplastics, the issues about unknowingly consuming microplastics are solely rising. The common individual takes in between 39,000 and 52,000 microplastic particles annually simply from food and drinks, based on previous analysis. This determine climbs to over 120,000 should you embrace airborne particles.
To raised perceive how this might have an effect on your well being, we talked with a household doctor. We mentioned what is taken into account a “protected” stage of microplastic consumption, which meals are the worst by way of microplastic content material and what steps you may take proper now to scale back your publicity.

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 potential,” Dr. Joseph Mercola, a board-certified household drugs osteopathic doctor, mentioned in an e mail.
Microplastics can enter our meals as a consequence of 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 line with the US Meals and Drug Administration, present evidence doesn’t suggest that the degrees of microplastics in meals are a threat to us. Nonetheless, you continue to would possibly need to reduce how a lot microplastics you passively eat. These are the most typical meals that include microplastics, and the measures you may undertake to scale back your plastic consumption.
Prime 10 meals in your eating regimen that include microplastics
1. Seafood
One of the important methods plastic particles find yourself in our meals is thru single-use plastics that break down and discover their approach into waterways and soil. Once 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 latest research revealed by Portland State College found a wide range of microplastics in 180 out of 182 tested seafood samples. Microfibers are the most typical kind of microplastic current, however this is not the one kind that results in our oceans.
Tips on how to keep away from it: When you cannot management what number of microplastics your fish ate earlier than it received 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). A majority of these seafood are uncovered to increased 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 bags, and even should you select paper tea baggage, there can nonetheless be microplastics in them. The difficulty is that when the luggage 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 in the billions, and nylon and cellulose tea baggage can launch them within the hundreds of thousands.
Tips on how to keep away from it: You do not have to cease ingesting tea. Swap to loose-leaf tea and spend money on a stainless steel diffuser to get pleasure from your tea freed from microplastics.
3. Rice
Rice can also 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. If you happen to use instantaneous rice packets, that quantity is 4 occasions increased, at 13 milligrams.
Tips on how to keep away from it: The research discovered that washing your rice can scale back plastic contamination by 20% to 40%, although it is value noting that the research used filtered water for rinsing.
4. Salt and sugar
While you prime off your dinner with a sprinkling of salt, you are getting an unintentional aspect of microplastics. It is exhausting to outrun salt. It is in nearly every 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 brands worldwide contained microplastics. This possible outcomes from environmental contamination and the manufacturing and packaging course of, which incorporates plastic. Microplastics have additionally been found in sugar.
Tips on how to 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 kind of nanoplastic researchers have found in plastic water bottles.
Tips on how to keep away from it: Ingesting faucet water from a stainless steel or glass container can scale back your threat of ingesting plastic particles.
6. Honey
You may not anticipate your honey to harbor microplastics, nevertheless it does, even when it is in a glass jar. Microplastic fibers could be traced again to bees and air pollution. One research exploring whether or not microplastics ingested or carried by honeybees had been then included into hives discovered that bees can proceed the dispersal of microplastics by honey.
Tips on how to keep away from it: Shopping for honey from native beekeepers who usually use extra pure and sustainable harvesting strategies might scale back the chance of microplastic contamination.
7. Fruits and veggies
Greens and fruits are an important a part of a balanced eating regimen. They’ll additionally include microplastics. One research that sampled fruit and vegetables discovered that apples were the most contaminated fruit and carrots had been essentially the most contaminated vegetable. How does this occur?
“Crops have been proven to uptake micro- and nanoplastics from soil by their root techniques, thereby contaminating the edible parts,” Mercola mentioned.
Many grocery shops additionally package deal fruit and greens in plastic to maintain them recent. In line with the FDA, there is not enough evidence 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.
Tips on how to keep away from it: Wash your fruit completely, peel when potential and go for native or natural produce.
8. Proteins
A latest 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 options, fish sticks or hen nuggets, harbor essentially the most microplastics, suggesting the microplastic contamination partly comes from food 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 could be contaminated by the soil or irrigation.
Tips on how to keep away from it: After studying that, you could be questioning what protein it is best 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 vital, 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, nonetheless, that extra analysis is required to grasp simply how consuming meals with microplastics impacts us. Nonetheless, although the long-term well being results stay beneath investigation, microplastics are one thing to be careful for and guard in opposition to should 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,” mentioned Mercola.
Different potential unwanted side effects are hormonal imbalances brought on by the endocrine-disrupting chemicals present in plastics. Microplastics also can absorb other 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 every thing. But it surely’s a good suggestion to reduce publicity the place you may.
Knowledgeable suggestions for lowering your consumption of microplastics
You possibly can minimize down by following this recommendation:
1. Watch out how a lot shellfish you eat
Shellfish like mussels, oysters and scallops have increased ranges of microplastics, so do not overdo it.
2. Keep away from food-storage containers fabricated from plastic
That is one in every of Mercola’s greatest recommendations 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 may retailer dry meals in plastic if it is advisable.
3. Keep away from plastic-wrapped meals
This may be simpler mentioned than achieved, nevertheless it’s one thing to try for in areas the place you may 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. rule of thumb is: Something plastic that is available in contact together with your meals must be swapped out for ceramic, glass, chrome steel or wooden.
To assist handle the general situation of microplastics in meals, you may set up a filter in your clothes-washing machine. If you happen to 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 quite a bit to find out about microplastics and their long-term implications for our well being when ingested. It could be exhausting to listen to they’re in so a lot of our meals, however that should not deter you from consuming properly. A balanced diet of protein, fruit and greens will guarantee your physique has sufficient gasoline to function and thrive — microplastics or not.
