Don’t toss out that old cutting board just yet! Some scientists say the fear around microplastics—the tiny bits of plastic found everywhere from our meals to our clothes—might be a bit overblown.
For years, researchers have warned that microplastics could be making their way into our bodies, potentially harming our health. However, a growing number of experts are questioning these claims. One researcher even referred to alarming studies as “a joke.”
Recent reports suggested that microplastics could be lurking in our brains and organs. But experts now argue that many of these findings might stem from errors in testing methods rather than actual evidence of plastic ingestion. Dusan Materic, a leading scientist at the Helmholtz Center for Environmental Research, criticized prior studies for painting a dramatic picture without solid backing.
Chemist Roger Kuhlman agreed, calling the evidence questionable. “This pushes us to rethink everything we assume about microplastics in our bodies,” he said, noting that many researchers make bold claims without sufficient proof.
One controversial study claimed that the average human brain might hold the weight of a plastic spoon in microplastics. Yet, a rebuttal from several scientists pointed out significant flaws in the study, such as poor contamination controls and lack of validation.
A key aspect of this debate revolves around a testing method known as Py-GC-MS. This technique vaporizes samples to identify their composition, but environmental chemist Cassandra Rauert pointed out that it can misidentify human fat as plastic, leading to misleading results. She also highlighted that the presence of plastic in internal organs is “biologically implausible” since tiny particles have a hard time passing through biological barriers.
Some experts suggest that rising obesity rates might explain certain health concerns better than household plastics do. Fazel Monikh, a nanomaterials expert, added that any plastic particles reaching sensitive organs like the brain would likely transform once inside the body.
Frederic Béen described the current research on microplastics as “super-immature,” warning that the rush to publish findings has led to shortcuts in scientific rigor. These flawed studies not only contribute to unnecessary panic but also fuel costly treatments that promise to remove plastic from the bloodstream—sometimes at exorbitant prices, reaching up to £10,000 (around $13,500).
While many researchers agree that plastics likely do enter the human body, they stress the need for more reliable methods to assess this issue accurately. Until we have clearer answers, experts recommend simple precautions, like using charcoal water filters and avoiding microwaving food in plastic containers.
