Plastic is in all places. From the meals we eat to the air we breathe, tiny particles of plastic — often known as “microplastics” — will 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 regularly, like say your handy-dandy plastic reducing board.
A current research printed by the journal, Ecotoxicology and Public Well being evaluated the quantity of microplastics present in a meals between two several types of plastic reducing boards. Carrots have been chopped on a reducing board made with polypropylene, and one other with polyethylene. Scientists evaluated what the whole publicity can be per particular person when utilizing all 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 may generate 15 milligrams of microplastics per minimize, and round 50 grams a yr — the equal of 10 plastic bank cards.
With so many microplastics being uncovered to our meals, ought to shoppers be apprehensive? 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 regularly, and if there are more healthy reducing board options we should always think about.
The truth of consuming microplastics from our cookware
At first, the research concerning microplastic consumption appear bleak. Proof means that microplastics will be present in our blood, our lungs, and even our placenta, and will be doubtlessly hazardous in direction of our bodily well being. A 2022 animal research in South Korea discovered microplastics may intrude 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 vital 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 direction of the unfavourable results these reducing boards can have towards human well being. “The presence of the plastics underneath 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 threat to shoppers,” he says.
Plus, the research that appears at microplastics doubtlessly harming human well being are all taking a look at correlation, with out making any outright claims as a result of the connection between the 2 remains to be tougher to outright conclude. So the declare that microplastics may cause most cancers? There’s really no actual scientific proof to again it.
“These fashions have limitations when evaluating human well being dangers,” says Dr. LeBeau. “The perfect option 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.”
To be able to really 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 sometimes are carried out by standardized animal fashions, as a result of asking a human to take action may border on being unethical.
“Whereas we might have publicity to microplastics, there could also be little organic interplay and the result’s that they’re really not a threat to human well being,” he concludes.
Ought to we change our reducing boards?
With a lot uncertainty round whether or not plastic reducing boards really 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 is not 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 typically in our water even when it’s been filtered), that the microplastics from reducing boards gained’t be making an enormous distinction.
Plus, Dr. Lebeau additionally brings up weighing the professionals and cons of utilizing different kinds of reducing boards. Whereas utilizing a wooden reducing board might appear to be a cleaner, safer possibility, all these merchandise are porous and might not be utterly disinfected correctly — a.ok.a., rising the danger 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 constructed from bamboo as a result of they’re denser and are much less porous than different wooden reducing boards, lowering your threat. Simply you should definitely clear it as totally as doable!
