简要总结
The consumption of fermented soy foods can alter the human microbiome and may confer health benefits. Researchers propose a line of inquiry to assess the effects of Q-Can Plus ("QC") fermented soy beverage in humans, assessing immunological, microbiological, and clinical parameters.
详细描述
The study will start with a detailed testing of the microorganisms present in the QC fermented soy liquid, using deep sequencing. Subsequently, the researchers will determine the effect of the QC fermented soy product on the microbiome and inflammation in lean and obese individuals, as obese individuals are known to have dysbiosis. The work on inflammatory changes will be supplemented by studies to investigate the cellular and molecular mechanistic pathways responsible for the biological action of QC fermented soy liquid.

结局指标
主要结局
Change in microbiome species proportion- Oral
时间窗: baseline to week 12
Microbiome analysis will be conducted by calculating the significance in changes in the proportion of species between the groups, and by principal component analysis (PCA) to identify patterns of shift in the microbiome populations in relation to QC-induced changes.
