After the chickens hatched, the scientists detected changes in the functional, morphological and microbial biomarkers in the blood, the duodenum (upper intestine) and the cecum (a pouch connected to the intestine).<\/p>\n<p>\u201cWe are consuming these nanoparticles on a daily basis,\u201d said Tako. \u201cWe don\u2019t really know how much we consume; we don\u2019t really know the long-term effects of this consumption. Here, we were able to demonstrate some of these effects, which is a key to understanding gastrointestinal health and development.\u201d<\/p>\n<p>Despite the finding, the scientists are not yet calling for an end to the use of these nanoparticles.<\/p>\n<p>\u201cBased on the information, we suggest simply being aware,\u201d Tako said. \u201cScience needs to conduct further investigations based on our findings. We are opening the door for discussion.\u201d<\/p>\n<p> The research is published in the 9 February 2023 issue of Antioxidants. <a href=\"https:\/\/doi.org\/10.3390\/antiox12020431\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/doi.org\/10.3390\/antiox12020431<\/a><\/p>\n<\/div><\/section><br \/>\n<div  class='av-social-sharing-box  avia-builder-el-7  el_after_av_textblock  avia-builder-el-last  av-social-sharing-box-minimal '><div class='av-share-box'><h5 class='av-share-link-description av-no-toc '>Share this<\/h5><ul class='av-share-box-list noLightbox'><li class='av-share-link av-social-link-facebook' ><a target=\"_blank\" aria-label=\"Share on Facebook\" href='https:\/\/www.facebook.com\/sharer.php?u=https:\/\/fei-online.com\/food-colouring-nanoparticles-may-affect-human-gut\/&#038;t=Food%20colouring%20nanoparticles%20may%20affect%20human%20gut' aria-hidden='false' data-av_icon='\ue8f3' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share on Facebook' rel=\"noopener\"><span class='avia_hidden_link_text'>Share on Facebook<\/span><\/a><\/li><li class='av-share-link av-social-link-twitter' ><a target=\"_blank\" aria-label=\"Share on Twitter\" href='https:\/\/twitter.com\/share?text=Food%20colouring%20nanoparticles%20may%20affect%20human%20gut&#038;url=https:\/\/fei-online.com\/?p=11197' aria-hidden='false' data-av_icon='\ue8f1' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share on Twitter' rel=\"noopener\"><span class='avia_hidden_link_text'>Share on Twitter<\/span><\/a><\/li><li class='av-share-link av-social-link-whatsapp' ><a target=\"_blank\" aria-label=\"Share on WhatsApp\" href='https:\/\/api.whatsapp.com\/send?text=https:\/\/fei-online.com\/food-colouring-nanoparticles-may-affect-human-gut\/' aria-hidden='false' data-av_icon='\uf232' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share on WhatsApp' rel=\"noopener\"><span class='avia_hidden_link_text'>Share on WhatsApp<\/span><\/a><\/li><li class='av-share-link av-social-link-linkedin' ><a target=\"_blank\" aria-label=\"Share on LinkedIn\" href='https:\/\/linkedin.com\/shareArticle?mini=true&#038;title=Food%20colouring%20nanoparticles%20may%20affect%20human%20gut&#038;url=https:\/\/fei-online.com\/food-colouring-nanoparticles-may-affect-human-gut\/' aria-hidden='false' data-av_icon='\ue8fc' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share on LinkedIn' rel=\"noopener\"><span class='avia_hidden_link_text'>Share on LinkedIn<\/span><\/a><\/li><li class='av-share-link av-social-link-mail' ><a  aria-label=\"Share by Mail\" href='mailto:?subject=Food%20colouring%20nanoparticles%20may%20affect%20human%20gut&#038;body=https:\/\/fei-online.com\/food-colouring-nanoparticles-may-affect-human-gut\/' aria-hidden='false' data-av_icon='\ue805' data-av_iconfont='entypo-fontello' title='' data-avia-related-tooltip='Share by Mail'><span class='avia_hidden_link_text'>Share by Mail<\/span><\/a><\/li><\/ul><\/div><\/div><\/p><\/div><div class=\"flex_column av_one_fifth  flex_column_div av-zero-column-padding   avia-builder-el-8  el_after_av_three_fifth  avia-builder-el-last  \" style='border-radius:0px;
