Some cooks have switched from plastic slicing boards to wood options. One research of plastic slicing boards discovered that they shed as many as dozens of grams of microplastics per particular person per 12 months.

It is a plastic world on the market.
About 460 million metric tons of the fabric are made every year, in keeping with the United Nations, and a few scientists are rising more and more frightened that microplastics that discover their method into our our bodies may very well be harming our well being.
A technique they get in? Meals. And never solely by way of meals itself — although they’re there — but additionally within the sundry instruments and different objects we use to organize and retailer what we eat every day.
Residence cooks chop into plastic slicing boards, warmth up plastic containers, sauté with plastic cooking utensils, encase components in plastic wrap and toss plastic detergent pods within the dishwasher — all of that are doable vectors for microplastics publicity.
“Some of the essential sources of microplastics is thru the meals that we eat,” says Tracey Woodruff, a professor on the College of California, San Francisco who research the influence of microplastics on human well being. “And it is extremely doubtless that lots of that comes from meals contact supplies.”
Here is what to find out about microplastics and meals preparation — and what you are able to do if you wish to purge your kitchen of the fabric.
Are microplastics harming people? The science is evolving
There’s nonetheless rather a lot we do not find out about how microplastics have an effect on people.
The tiny particles — which vary in measurement from roughly the width of a pencil eraser to thinner than the diameter of a strand of DNA — have been found in lots of components of the human physique, together with the guts, lungs and placenta.
Plastic meals containers may be changed with glass or steel ones. Public well being specialists warn towards heating meals in plastic.

Whereas some research have indicated that animals undergo in poor health well being results as a result of presence of microplastics, much less is thought about how the fragments influence us. The Meals and Drug Administration says the “total scientific proof doesn’t exhibit that ranges of microplastics or nanoplastics present in meals pose a threat to human well being.” However some early analysis finds doable hyperlinks between well being issues and the buildup of those particles.
Susanne Brander, an ecotoxicologist at Oregon State College, advised NPR in December that analysis displaying detrimental well being results from microplastics publicity in animals may present clues about what’s occurring to individuals.
“If that is occurring in fish and in rodents in experiments which are being peer-reviewed and printed, it is most likely occurring in us too,” Brander stated. “We simply have not demonstrated it but.”
As a result of analysis reveals that people are persevering with to be uncovered to microplastics, UCSF’s Woodruff recommends that individuals ought to attempt to restrict their contact with the fabric.
“If we wait to attempt to put a finer level on the science, that signifies that we’re additionally regularly being uncovered, and that would result in extra hostile well being results, a few of them which we have not even recognized but,” she stated.
Need to ditch plastic kitchen instruments? Here is what you are able to do
If you happen to resolve you need to cut back your use of plastic within the kitchen, there’s loads you are able to do. However do not try and toss each certainly one of your plastic objects instantly, says Anne-Marie Bonneau, creator of The Zero-Waste Chef.
“I would not counsel simply taking all your stuff and pitching it. Possibly when it breaks, exchange it,” Bonneau says. “Do not attempt to do all of this directly.”
Tracey Woodruff, a professor on the College of California, San Francisco who research the influence of microplastics on human well being, stated it is doubtless that many individuals ingest microplastics from “meals contact supplies.”

Bonneau determined to “break up” with plastics in 2011 over considerations about air pollution but additionally got here to acknowledge the potential well being advantages of avoiding the artificial within the kitchen.
As a substitute of utilizing a plastic slicing boardshe makes use of wood ones. One current research referred to as plastic slicing boards a “probably vital supply of microplastics in human meals” and located {that a} polyethylene chopping board may shed between 7.4 and 50.7 grams of microplastics per particular person per 12 months.
Bonneau shops meals in glass or steel containers and saves all her jars to reuse later. Heating plastic containers could cause tens of millions of microplastics and billions of nanoplastic particles to be launched, one research discovered. (Microplastics have turned up in takeout meals containers, plastic water bottles, paper espresso cups and extra.)
Plastic wrap is nowhere to be present in Bonneau’s kitchen, which has pressured her to grow to be resourceful. “Plenty of recipes for bread let you know find out how to make the dough, and to proof it, they will say cowl the bowl with plastic wrap,” she says. “Effectively, you possibly can simply put a plate on high of the bowl. Or the lid of a pot.”
She has cotton dish towels and reusable fabric produce luggage that she brings to farmers markets and grocery shops. Bonneau additionally makes use of cellulose kitchen sponges as an alternative of the frequent plastic options.
Residence cooks also can use stainless-steel or cast-iron pots and pans quite than nonstick cookware, which is commonly made with PFAS, a gaggle of chemical substances which have been linked to well being issues in people.
Making the swap in a restaurant
Chef Edward Lee ditched plastic at his nonprofit restaurant Shia in Washington, D.C., to check out extra sustainable enterprise practices that may very well be adopted by different eateries. Meaning utilizing wood slicing boards, swapping plastic deli containers for steel and glass substitutes and changing plastic wrap with options equivalent to parchment paper, beeswax paper, muslin and cheesecloth. The restaurant makes use of paper takeout containers and would not give diners to-go utensils, since Lee says most of them are taking their meals house anyway.
However not the whole lot was so simply changed, equivalent to the long-lasting plastic restaurant squeeze bottles that Shia has sworn off. Employees members as an alternative retailer sauces in separate containers and blend vinaigrettes as they’re wanted. “One of many by-products of eliminating squeeze bottles is that every one our vinaigrettes are brisker, as a result of we’ve got to make them to order,” Lee stated.
There are trade-offs to slicing out plastic, in keeping with Lee. Some nonplastic options are dearer, and kitchen employees members must be extra cautious when dealing with objects like glass that would simply break if dropped.
However he stated the elimination of plastics at Shia has led to a constructive cultural shift amongst employees members, lots of whom have additionally decreased their plastic use at house.
“Being surrounded by lots of disposables … your perspective turns into extra disposable,” Lee stated. “After we’re surrounded by permanence, we’re a bit of bit extra centered — we’re a bit of bit extra cautious.”
He added: “When you do that, you understand there isn’t any going again.”
