Matcha green tea is made from powdered green tea leaves. Unlike regular green tea, Matcha green tea is believed to exert beneficial effects on the gut microbiota, as it is richer in nutrients such as tea catechins and insoluble dietary fiber. In the present study, we aimed to investigate the effects of consumption of Matcha green tea on the gut microbiota. Human participants were randomly assigned to a placebo (n = 16) or a Matcha green tea (n = 17) drink group and asked to drink the treatments for two weeks. Feces were collected from the participants pre- and post-treatment and fecal microbiota composition was analyzed by 16S rRNA metagenomic sequencing. The beta-diversity of microbial composition significantly (p<0.05) changed in MGT group but not in placebo group. In addition, the number of unique bacterial genera significantly (p<0.05) changed in the Matcha green tea group was 30, while it was only 3 in the Placebo group. Increase and decrease in abundances of Coprococcus and Fusobacterium, respectively, in the gut microbiota of Matcha green tea group, conferred potential health benefits to the host. The present study was registered in the UMIN Clinical Trial Registry (UMIN000043857).
