Does Science Back Up Kefir’s Ability to Protect Your Microbiome?

It appears the answer may be yes.

A study out of Brazil, published in the International Journal of Antimicrobial Agents in 2005, tested kefir and its insoluble polysaccharide kefiran for their antimicrobial activity.

The researchers tested their effectiveness against several strains of bacteria, including candida albicans, a type of bacteria that, when overgrown, commonly leads to gut imbalances, mood disorders, hormonal disorders, fatigue, and more.

What they found was very encouraging.

The researchers tested a 70% kefir gel on induced skin lesions on rats.

(Note: I am against ALL animal testing here at Pursuit of Great. This information is presented for informational purposes only, not in support of the study’s methods.)

What they found was that the gel was effective against all types of bacteria tested, with the highest effectiveness being found against streptococcus pyogenes.

Just as importantly, they also tested a pharmaceutical option, the topical steroid neomycin-clostebol. After seven days, the kefir gel showed a protective effect on skin connective tissue and enhanced wound healing when compared to neomycin-clostebol.

This is not to say that you should ditch your prescriptions in favor of kefir, but it is an indicator of kefir’s effectiveness against forms of harmful bacteria.

The good news is, as kefir’s health benefits become more widely known, the options on store shelves continue to grow. Numerous varieties of kefir can now be found in just about any grocery store, ranging from plain options to other types mixed with fruit juices that have an almost dessert-like, frozen yogurt type of flavor.

I hope you found this information helpful! Stay tuned as we continue to dig up the research on kefir and other amazing, healing foods and nutrients. Check out our databases for more can come back often.
