Niedrige Dosen von Nanoplastik über die Nahrung bei Mäusen über einen Zeitraum von 3 Monaten haben nachweislich Auswirkungen auf die Integrität der Darmbarriere, die Zusammensetzung der Mikrobiota und die Leberfunktion, wobei die Auswirkungen durch eine fett- und zuckerreiche Ernährung verstärkt werden

>It was found that exposure to low doses of polystyrene nanoplastics over the 90-day period had strong diet-dependent effects.
>
>Gut barrier integrity was altered, an effect that was amplified in mice consuming the Western-style diet. Gut microbiota composition was also altered, an effect that was amplified in mice consuming the standard diet.
>
>In the liver, exposure to low doses of nanoplastics disrupted fat metabolism regardless of diet, but glucose intolerance was more pronounced in mice consuming the Western-style diet. This effect was seen even though nanoplastics did not appear to cross the gut barrier. The above changes were associated with greater mass gain in the mice.
>
>The study’s results illustrate that low doses of nanoplastics without chemical additives can alter gut and liver function in a diet-dependent manner.

[A Western-style diet shapes the gut and liver responses to low-dose, fit-for-purpose polystyrene nanoplastics in mice – Environmental Science: Nano (RSC Publishing)](https://pubs.rsc.org/en/content/articlelanding/2026/en/d5en00866b)

How did they remove or account for the nano/micro plastics from the standard chow? Wouldn’t that baseline already be an approximation for the amount that we consume?
