Suppression of intestinal ROS (reactive oxygen species)<\/h5>\n<p class=\"article-card__excerpt rte\"><strong>Research:<\/strong>Xiao, J., &amp; H\u00f6gger, P. (2015). Dietary polyphenols and type 2 diabetes: current insights and future perspectives. Current Medicinal Chemistry, 22(1), 23-38.<\/p>\n<p class=\"article-card__excerpt rte\"><strong>Conclusion:<\/strong>EGCG, as the main component of tea polyphenols, has strong antioxidant activity, which can scavenge reactive oxygen species (ROS) in the intestinal tract and reduce the damage caused by oxidative stress to the intestinal tract.<\/p>\n<p class=\"article-card__excerpt rte\"><strong>Research:<\/strong>Kim, H. S., Quon, M. J., &amp; Kim, J. A. (2014). New insights into the mechanisms of polyphenols beyond antioxidant properties; lessons from the green tea polyphenol, epigallocatechin 3-gallate. Redox Biology, 2, 187-195.<\/p>\n<p class=\"article-card__excerpt rte\"><strong>Conclusion:<\/strong>EGCG significantly reduces intestinal ROS levels and protects intestinal barrier function by modulating the activity of antioxidant enzymes such as SOD and glutathione peroxidase.<\/p>\n<h5 class=\"article-card__excerpt rte\">2. Enhancement of mucus layer thickness<\/h5>\n<p class=\"article-card__excerpt rte\">Research: Shimizu, M., &amp; Weinstein, I. B. (2005). Modulation of key signaling pathways by green tea polyphenols. Journal of Nutritional Biochemistry, 16(2), 68-76.<\/p>\n<p class=\"article-card__excerpt rte\">CONCLUSION: EGCG enhances the thickness of the intestinal mucus layer by regulating signaling pathways (e.g., MAPK and NF-\u03baB) in intestinal epithelial cells and promoting mucin (MUC2) expression.<\/p>\n<p class=\"article-card__excerpt rte\">Research: Chen, Y., Liu, T., Wang, K., Hou, C., Cai, S., Huang, Y., \u2026 &amp; Liu, Y. (2016). Epigallocatechin-3-gallate attenuates mucus synthesis and secretion in a cigarette smoke-induced chronic obstructive pulmonary disease model. Food &amp; Function, 7(10), 4472-4481.<\/p>\n<p class=\"article-card__excerpt rte\">CONCLUSION: EGCG enhances the protective effect of the mucus layer by inhibiting the release of inflammatory factors (e.g., IL-6 and TNF-\u03b1) and promoting mucin synthesis.<\/p>\n<h5 class=\"article-card__excerpt rte\">3. Enhancement of colonization abundance of AKK bacteria (Akkermansia muciniphila)<\/h5>\n<p class=\"article-card__excerpt rte\"><strong>Research:<\/strong>Roopchand, D. E., Carmody, R. N., Kuhn, P., Moskal, K., Rojas-Silva, P., Turnbaugh, P. J., &amp; Raskin, I. (2015). Dietary polyphenols promote growth of the gut bacterium Akkermansia muciniphila and attenuate high-fat diet-induced metabolic syndrome. Diabetes, 64(8), 2847-2858.<\/p>\n<p class=\"article-card__excerpt rte\"><strong>Conclusion:<\/strong>EGCG significantly increases the abundance of AKK bacteria colonizing the gut by promoting the secretion of mucin, which provides the substrate required for their growth.<\/p>\n<p class=\"article-card__excerpt rte\"><strong> Research:<\/strong>Anh\u00ea, F. F., Pilon, G., Roy, D., Desjardins, Y., Levy, E., &amp; Marette, A. (2016). Triggering Akkermansia with dietary polyphenols: A new weapon to combat the metabolic syndrome? Gut Microbes, 7(2), 146-153.<\/p>\n<p class=\"article-card__excerpt rte\"><strong>Conclusion:<\/strong>EGCG creates a favorable environment for the survival of AKK bacteria by regulating the thickness and composition of the intestinal mucus layer, thus improving the balance of intestinal flora.<\/p>\n<h4 class=\"article-card__excerpt rte\">Summarize<\/h4>\n<h4 class=\"article-card__excerpt rte\">The above literature suggests that the tea polyphenol EGCG is able to improve intestinal health by inhibiting intestinal ROS, enhancing the thickness of the mucus layer, and boosting the colonization abundance of AKK bacteria through a polyphenol-mucin interaction mechanism.
