Plastic is all over the place. From the food we eat to the air we breathe, tiny particles of plastic — also referred to as “microplastics” — could be present in virtually something. Not solely does plastic trigger actual havoc on our oceans and take centuries to decay, inflicting much more of an environmental disaster, however toxicologists have questioned whether or not consuming microplastics can negatively impression well being. Particularly if there are items of plastic you’re utilizing frequently, like say your handy-dandy plastic cutting board.
A current research printed by the journal, Ecotoxicology and Public Health evaluated the quantity of microplastics present in a meals between two several types of plastic reducing boards. Carrots had been chopped on a reducing board made with polypropylene, and one other with polyethylene. Scientists evaluated what the entire publicity can be per particular person when utilizing a lot of these plastic reducing boards. On the finish of the research, they discovered these plastic reducing boards resulted in 1,114 microplastic particles (items of plastic lower than 5 millimeters lengthy) on the carrots every time the board was used. This implies a plastic reducing board might generate 15 milligrams of microplastics per lower, and round 50 grams a yr — the equal of 10 plastic bank cards.
With so many microplastics being uncovered to our meals, ought to customers be nervous? The Kitchn spoke with Alex LeBeau, PhD, MPH, CIH, a toxicologist and licensed industrial hygienist on the impression on human well being from utilizing plastic reducing boards frequently, and if there are more healthy cutting board options we should always contemplate.
The fact of consuming microplastics from our cookware
At first, the research relating to microplastic consumption appear bleak. Evidence suggests that microplastics could be present in our blood, our lungs, and even our placenta, and could be probably hazardous in the direction of our bodily well being. A 2022 animal study in South Korea discovered microplastics might intervene with digestive, respiratory, endocrine, and even our reproductive techniques.
And but, whereas this analysis will make a plastic reducing board-user appear cautious, it’s essential to notice that the science remains to be new and really restricted. Dr. LeBeau factors out that whereas the current research evaluating reducing boards does show the discharge of microplastic particles, it doesn’t make any claims in the direction of the damaging results these reducing boards can have towards human well being. “The presence of the plastics beneath restricted simulated situations identifies them as a possible publicity supply, however it’s unclear if they’re a human well being hazard or pose any danger to customers,” he says.
Plus, the research that appears at microplastics probably harming human well being are all correlation, with out making any outright claims as a result of the connection between the 2 remains to be more durable to outright conclude. So the declare that microplastics could cause most cancers? There’s truly no real scientific evidence to back it.
“These fashions have limitations when evaluating human well being dangers,” says Dr. LeBeau. “The best technique to perceive the impacts of ‘microplastics’ consists of figuring out the well being results in people over a time period or by standardized animal mannequin research.”
So as to truly decide long-term dangers, Dr. Lebeau says a research would wish to have a look at the impacts of microplastics on human well being over an extended time period. These research additionally usually are carried out by standardized animal fashions, as a result of asking a human to take action might border on being unethical.
“Whereas we could have publicity to microplastics, there could also be little organic interplay and the result’s that they’re truly not a danger to human well being,” he concludes.
Ought to we substitute our reducing boards?
With a lot uncertainty round whether or not plastic reducing boards truly negatively have an effect on human well being, the query nonetheless stands: ought to we eliminate them simply in case?
As of now, the reply isn’t any. Dr. Lebeau says that we’re already consuming so many microplastics all through our day (like in our meals we eat from manufacturing, and even generally in our water even when it’s been filtered), that the microplastics from reducing boards received’t be making an enormous distinction.
Plus, Dr. Lebeau additionally brings up weighing the professionals and cons of utilizing different varieties of reducing boards. Whereas utilizing a wooden reducing board could look like a cleaner, safer choice, a lot of these merchandise are porous and will not be utterly disinfected correctly — a.ok.a., growing the chance of food-borne sickness.
If you want to keep away from each altogether, the USDA recommends changing your plastic and wooden reducing boards with ones which might be produced from bamboo as a result of they’re denser and are much less porous than different wooden reducing boards, lowering your danger. Simply make sure to clear it as completely as attainable!
