To make these particles biodegradable, researchers created plastics from plant starch instead of petroleum. An initial study published in ACS&#8217; Journal of Agricultural and Food Chemistry shows how animals consuming particles from this alternative material developed health problems such as liver damage and gut microbiome imbalances.<\/p>\n<p>The researchers compared three groups of five mice: one group consuming normal chow and two groups consuming food infused with starch-based microplastics. The doses (low and high) were calculated and scaled from what an average human is expected to consume daily. They fed the mice for 3 months and then assessed the animals&#8217; organ tissues, metabolic functions and gut microbiota diversity. Mice exposed to the starch-based plastic particles had:<\/p>\n<p>Multiple damaged organs, including the liver and ovaries, with more pronounced damage in the high-dose group. However, mice eating normal chow showed normal organ tissue biopsies. Altered glucose management, including significant abnormality in triglycerides (a type of fat) and disruption in molecular biomarkers associated with glucose and lipid metabolism, compared to mice fed normal chow. Dysregulated genetic pathways and specific gut microbiota imbalances, which the researchers suggest could alter microplastic-consuming animals&#8217; circadian rhythms.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.sciencedaily.com\/releases\/2025\/04\/250409114956.htm\">Science Daily<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/7-695\/\">Starch-based microplastics could cause health risks in mice<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[22],"tags":[575,525,17908,902],"class_list":["post-138957","post","type-post","status-publish","format-standard","hentry","category-news","tag-environmental-news-en","tag-health","tag-mice","tag-microplastics"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/138957","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/comments?post=138957"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/138957\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/media?parent=138957"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/categories?post=138957"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/tags?post=138957"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
