đą Can Fibre Help Your Body Get Rid of Microplastics? What the Research Actually Says
Back from a lovely weekend away with my boys, and diving straight back into the world of âis this actually true?â health claims. One thatâs been circulating lately: âFibre is your best bet against microplastics.â
Hereâs the simple, evidenceâbased version.
The short answer:
Fibre might help move microplastics through the gut â but the science is early, mostly from animal studies, and nowhere near a proven detox method.
What we know so far:
Microplastics have been found in human blood, so some particles can cross into the body.
Certain fibres (like chitosan) helped rats excrete more microplastics â but we donât have human trials yet.
Insoluble fibre may help things move along; soluble fibre may form a gel that traps particles â but these are still theories.
Whatâs missing:
No strong human evidence. No confirmed mechanism. And definitely no âfibre flushes out microplasticsâ guarantee.
The real takeaway:
Eating more fibre is great for digestion, heart health, and the gut microbiome â and most adults donât get enough anyway. But using fibre specifically to remove microplastics is still an emerging idea, not a proven solution.
And hereâs the part the viral clips usually skip:
Reducing your exposure to plastics in the first place matters far more than trying to âdetoxâ them later.
Simple, realistic steps include:
Choosing glass or stainless steel for food storage
Avoiding microwaving food in plastic
Using refillable bottles and filters instead of singleâuse plastics
Cutting down on heavily packaged foods
Opting for natural fibres when possible
