Kimchi May Beneficially Alter Gut Bacteria of Obese Women

Studies have shown that the gut bacteria in obese people differs from that of people of average weight. A recent study suggests that eating fresh or fermented kimchi, which contains beneficial lactobacilli bacteria, may change the bacterial populations in the gut and affect metabolic pathways for obese women.

Participants in the study included 24 obese women who were given either fresh or fermented kimchi daily for eight weeks. At the conclusion of the study, the researchers found that both the fresh and the fermented kimchi were associated with change gene expression linked to metabolism, immunity, blood circulation, digestion, and blood pressure.  The changes were more evident in the fermented kimchi group.

They also noted a reduction in the ratio of Firmicutes bacteria to Bacteroidetes bacteria in the fermented kimchi group. That ratio has been shown to be a biomarker for obesity.


Researchers from Washington University in St. Louis conducted the study. It was published online ahead of print on March 23, 2015, in Molecular Nutrition & Food Research.


Previous studies suggest that lactobacillus may be useful for improving skin disorders, high cholesterol, lactose intolerance, Lyme disease, hives, and to boost the immune system.


If you’re looking to add more of this probiotic strain to your diet, it can be found in kefir, miso soup, and kimchi. If those foods don’t appeal to you, consider a high quality supplement that is packaged with protection from air and light.
