Tempeh consumption enhanced beneficial bacteria in the human gut
Journal Title: Food Research - Year 2019, Vol 3, Issue 1
Abstract
It has been known that human gut microbiota modulates host health and the composition is affected by lifestyle, including the availability of dietary fiber. Tempeh, a kind of traditional fermented food from Indonesia, is rich in soluble fibers and microbial consortia. A previous study showed that tempeh could enhance IgA production and modulate gut microbiota composition in rats. Meanwhile, in human, tempeh supplementation for 16 days has increased the number of Akkermansia muciniphila significantly. Many Indonesians consume tempeh on a daily basis, but the effect of tempeh consumption for a longer period of time in human remains to be investigated. Therefore, the objective of this study was to investigate the effect of tempeh consumption in human for longer term, especially its effect in modulating gut microbiota composition. A total of sixteen (16) healthy females participated in this study. For the first 7 days, they were not allowed to consume any soy product; followed by 28 days of 100 gram of tempeh (n=10), or 200 mL of soymilk (n=6) consumption. Analysis of gut microbiota showed that soymilk and tempeh supplementation generated different profiles. Twenty-eight days of tempeh supplementation seemed to improve metabolic health markers better than soymilk treatment; significantly enhancing the presence of Bifidobacterium and A. muciniphila populations compared to those at the beginning of the study.
