Researchers from the University of Nottingham have determined that standard kefir, when paired with prebiotic fiber, might surpass the efficacy of common omega-3 supplements in combating persistent inflammation. The findings of their study have been featured in the Journal of Translational Medicine (JTM).
The experiment involved contrasting three methods of immune system support: taking omega-3 fatty acids, consuming prebiotic fiber, or ingesting a synbiotic—a blend of fermented kefir and a broad spectrum of dietary fibers. Over a six-week period, healthy volunteers supplemented with one of these options. The synbiotic group exhibited the most significant reduction in systemic inflammatory markers present in the bloodstream.
Kefir is home to live probiotic bacteria and yeasts generated through the fermentation of milk by kefir grains. When combined with fiber, a synbiotic effect is established: the fibers function as a growth medium for the beneficial microbes, boosting their proliferation and the subsequent production of butyrate. This compound is recognized for its anti-inflammatory properties and its capacity to modulate immune responses.
“While all three methods resulted in a decrease in inflammation, the synbiotic—the combination of fermented kefir and diverse prebiotic fiber—displayed the strongest and most comprehensive impact,” commented the study’s lead investigator, Dr. Amrita Vijay.
According to the scientists, these outcomes highlight the critical function of the interplay between the gut microbiota and dietary fibers in maintaining overall wellness. Consistent intake of synbiotics could aid in preventing cardiovascular and metabolic conditions, which are closely linked to chronic inflammation. However, the authors stress the necessity for further studies to validate these effects over the long term.
