Introduction

Primary metabolites such as carbohydrates, amino acids, and fatty acids, which are widely present in animal and plant cells, are essential for cell structure and basic metabolism

Tea ( Camellia sinensis ), the second most consumed beverage in China for thousands of years, can generally be divided into three main categories (green tea, oolong tea, and black tea), which differ in their production methods and chemical composition

Compared to oolong or black tea, green tea is much higher in polyphenols because the tea leaves are processed through different methods after they are harvested

In addition to the inhibition of NF-κB, AP1 and STAT transcription factors and leukocyte and T cell infiltration, activation of the cytoprotective system may contribute to the therapeutic benefit of tea polyphenols in colitis

Figure 2 Tea polyphenols inhibit colon inflammation by down-regulating inflammatory genes and up-regulating phase II antioxidant/detoxification genes

One study demonstrated that the fecal microbiota of green tea and black tea extract-treated donor mice was protective against DSS-induced colitis in mice by modulating microbiota composition
