Another study has determined the health benefit of probiotics and has found that consuming probiotics can diminish the fat accumulation in the liver.
Three pobiotic strain from the Collection Nationale de Cultures de Microorganismes (CNCM) of the Pasteur Institute: Lactobacillus paracasei CNCM I-4034, Bifidobacterium breve CNCM I-4035 and Lactobacillus rhamnosus CNCM I-4036, were used in this study and administered to Zucker rats.
Zucker rats contain a mutation in the gene that codifies the receptor or leptin, a hormone that transmits a sensation of satiety to the organism. As a result of this mutation the rats are obese and among the best characterized genetic models.
The administration of probiotics led to much lower accumulation of lipids (most of them triacylglycerides) in the liver compared to the control group fed with a placebo. The rats also had a lower levels in proinflamatory molecules (tumor-a necrosis factor, interleukin 6 and liposacarid) in the serum of rats fed with probiotics.
