"Tuocha tea, as a unique fermented tea, has attracted much attention due to its rich bioactive ingredients. These ingredients improve the gut environment and promote overall health through multiple mechanisms."
Bioactive components of Tuocha tea and intestinal health
The bioactive ingredients of Tuocha tea promote gut health in several ways.
(1) They are able to reduce the abundance of harmful bacteria (such as Bacteroids and Oscillibacter), reduce inflammation and endotoxin production, and thus improve intestinal integrity.
(2) The tea also increased the abundance of beneficial bacteria, such as Faecalibaculum, which was strongly associated with significantly increased levels of short-chain fatty acids (SCFAs), which positively affect gut health.(3) The post-fermentation process of the Tuocha tea involves the role of a variety of microorganisms, which are able to break down the complex components of the Tuocha tea to produce beneficial metabolites that further promote intestinal health.
The influence of Tuocha tea on obesity
The bioactive ingredients of Tuocha tea can alleviate obesity by altering the gut microbiota:
(1) Improving the intestinal environment: Oxidized tea polyphenols and other components in Tuocha tea can promote the growth of beneficial flora. Studies have shown that Tuocha tea extract can significantly increase the diversity of intestinal flora in obese mice induced by a high-fat diet and inhibit the growth of harmful bacteria associated with obesity.
(2) Regulation of metabolic pathway: By regulating intestinal flora, tuocha tea affects downstream metabolic pathways, promotes fat decomposition and energy consumption, reduces intestinal permeability, reduces inflammatory response, and increases the level of SCFAs.
(3) Enhance intestinal barrier function: The components of tuocha tea can up-regulate the expression of tight junction protein in intestinal epithelial cells, enhance the integrity of the intestinal barrier, reduce the level of endogenous lipopolysaccharide, and thus reduce systemic inflammatory response.
Effect of tuocha tea on diabetes mellitus
The bioactive ingredients of tuocha tea alleviate diabetes by shaping the gut microbiota:
(1) Changing the structure of intestinal flora: Studies have shown that Shutuocha tea can significantly reduce the proportion of Firmicutes and Bacteroidetes in diabetic rats and increase the abundance of beneficial bacteria such as lactobacillus. These changes are closely related to improving glucose metabolism.
(2) Promote the production of SCFAs: Certain microorganisms are believed to produce SCFAs in the gut flora. SCFAs play an important role in regulating metabolism and inflammatory response, helping to reduce blood sugar levels.
(3) Improve intestinal permeability and reduce inflammation: Tea extract can increase the diversity of intestinal flora and enhance the abundance of microorganisms negatively associated with inflammation, thereby promoting weight loss and improving diabetes.
