Based on animal and in vitro studies, nanoplastics (plastic particles <1 μm) can disrupt the gut microbiome, potentially impacting health. Here’s how: Dysbiosis: Nanoplastics alter microbial composition, often reducing beneficial bacteria like Bifidobacterium and Lactobacillus (key for short-chain fatty acid production and gut barrier health) while increasing opportunistic pathogens like Proteobacteria or Firmicutes. For example, […]
