It has been estimated that people devour between 39,000 and 52,000 microplastic particles annually, and a 2024 scoping evaluation decided that they have been present in eight out of 12 human organ systems. You would possibly discover them within the air, your water, the gadgets you use to prepare your food and even within the meals you eat. All of those sources can contribute to microplastics getting into your physique.
To search out out which meals usually tend to include microplastics and what we will do to cut back the quantity of them that we devour, we consulted a health care provider.

What number of microplastics are thought-about unsafe?
“There is no such thing as a formally established ‘secure’ or ‘unsafe’ stage of microplastic consumption. It is smart to need your publicity to be as little as attainable,” Dr. Joseph Mercola, a board-certified household drugs osteopathic doctor, mentioned in an electronic mail.Â
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 varied methods microplastics can find yourself in meals. Plastic packaging, utensils and containers are extra sources.Â
In accordance with the US Meals and Drug Administration, present evidence doesn’t suggest that the degrees of microplastics in meals are a threat to us. Nevertheless, you continue to would possibly need to decrease how a lot microplastics you passively devour. These are the commonest meals that include microplastics, and the measures you possibly can undertake to cut back your plastic consumption.
The highest 8 meals in your food plan that will include microplastics
1. Seafood
One of the vital methods plastic particles find yourself in our meals is thru single-use plastics that break down and discover their means 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 current research printed by Portland State College found a wide range of microplastics in 180 out of 182 tested seafood samples. Microfibers are the commonest kind of microplastic current, however this is not the one kind that leads to our oceans.
Learn how to keep away from it: When you cannot management what number of microplastics your fish ate earlier than it acquired 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). A majority of these seafood are uncovered to larger quantities of microplastics. Additionally, select seafood on the retailer that makes use of sustainable packaging, not plastic wrap.Â
You would possibly need to forego tea luggage to cut back your microplastic publicity.
2. Tea luggage
Polypropylene is commonly used to make tea bags, and even when you select paper tea luggage, they will nonetheless include microplastics. The difficulty is that when the baggage contact scorching water, microplastics could also be launched into your tea.Â
Researchers on the Autonomous College of Barcelona found that polypropylene tea luggage can launch plastic particles in the billions, and nylon and cellulose tea luggage can launch them within the tens of millions.
Learn how to keep away from it: You do not have to cease consuming tea. Change to loose-leaf tea and put money into a stainless steel diffuser to get pleasure from your tea freed from microplastics.
3. Rice
Rice can 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. If you happen to use on the spot rice packets, that quantity is 4 instances larger, at 13 milligrams.
Learn how to keep away from it: The research discovered that washing your rice can cut back plastic contamination by 20% to 40%, although it is value noting that the research used filtered water for rinsing.
4. Salt and sugar
Whenever you high off your dinner with a sprinkling of salt, you are getting an unintentional facet of microplastics. It is onerous to outrun salt. It is in nearly every part 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 doubtless outcomes from environmental contamination and the manufacturing and packaging course of, which incorporates plastic. Microplastics have additionally been found in sugar.
Learn how to keep away from it: To cut back your publicity to microplastics in your salt and sugar, you should purchase them packaged in glass or cardboard.
A reusable stainless-steel or glass water bottle shouldn’t be solely higher for the surroundings, however they’re microplastic-free.
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 comprised 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 kind of nanoplastic researchers have found in plastic water bottles.
Learn how to keep away from it: Ingesting faucet water from a stainless steel or glass container can cut back your threat of ingesting plastic particles.
6. Honey
You may not anticipate your honey to harbor microplastics, however 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 have been then integrated into hives discovered that bees can proceed the dispersal of microplastics by means of honey.
Learn how to keep away from it: Shopping for honey from native beekeepers who usually use extra pure and sustainable harvesting strategies might cut back the chance of microplastic contamination.
7. Fruits and veggies
Greens and fruits are a necessary a part of a balanced food plan. They’ll additionally include microplastics. One research that sampled fruit and vegetables discovered that apples were 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 means of their root techniques, contaminating the edible parts,” Mercola mentioned.
Many grocery shops additionally package deal fruit and greens in plastic to maintain them recent. In accordance 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 possibly can anyway.
Learn how to keep away from it: Wash your fruit completely, peel when attainable and select native or natural produce.
Remember to clean your produce when you get house.
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 options, fish sticks or rooster nuggets, harbor probably the most microplastics, suggesting the microplastic contamination partly comes from food processing. The research discovered that breaded shrimp had a median of 300 microplastic items per serving. Plant-based nuggets had 100 items per serving.
Meals processing is not the one means 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 means of the soil or irrigation.Â
Learn how to keep away from it: After studying that, you could marvel what protein you need to eat. The truth is that extra analysis is required to know the precise ranges and their impression on our well being. Our our bodies want protein to operate, so getting sufficient is vital, no matter your chosen supply.
What can microplastics in meals do to your well being?
So, do all meals include microplastics? I can not say for certain. I can let you know, nevertheless, that extra analysis is required to know 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 when 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 will trigger irritation and tissue harm,” Mercola mentioned.
Different potential unwanted effects are hormonal imbalances attributable to the endocrine-disrupting chemicals present in plastics. Microplastics may also absorb other environmental toxins and introduce them into the physique.
There is no established secure stage of microplastics and we won’t fully outrun them: They’re in every single place and in every part. Nevertheless it’s a good suggestion to attenuate publicity the place you possibly can.
Professional ideas for decreasing your microplastic consumption
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 manufactured from plastic
That is considered one of Mercola’s greatest 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 mentioned than executed however it’s one thing to attempt for in areas the place you possibly can change.
4. Do away with 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 great 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 tackle the general concern of microplastics, you possibly can 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 lots to study microplastics and their long-term implications for our well being when ingested. It may be onerous 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 gas to operate 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 among 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. If you happen to’re on the lookout for 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.
