eat probiotic yogurt might deepen the way the bacterium in your gut break down the carbs you eat , a new study suggest .
Researchers found that eating yogurt daily did not vary the species of microbe in the intestines of multitude , or shiner transplanted with human gut microbe .
However , when the researchers look at the bodily process of bacterial enzymes in the mice ’s guts , they discovered significant changes in some of the enzymes — particularly those involved in metabolizing carbohydrate .
Essentially , the live bacterium in the yogurt allowed the mice to break down certain classes ofcarbohydratesmore efficiently , the study showed , and many of these changes also occurred in the study ’s 14 human player .
" It ’s interesting that just by virtue of introducing species , you may get quite dramatic changes in the expression of genes in the gut microbes , " say Susan Lynch , an associate prof of medicine at the University of California , San Francisco , who was not involved in the research .
But she says that declamatory subject area are needed to really empathize how the probiotics , or " good bacteria , " move the bacterial communities in multitude ’s gut .
The effects of probiotics
Our guts are home to swarm of bacterium , known collectively as the microbiome . These communities help us in a variety of ways , such as harvesting Energy Department from the nutrient we eat , preventing the growth of harmful bacterium and producing nutrient such as vitamin K and H.
Studies have shown that probiotic microflora , such as those found in yoghurt , can help with certain intestinal take , such as irritable gut syndrome . late inquiry suggest that ingesting probiotics may even affect our conduct and could somedaytreat economic crisis .
But despite the purport wellness welfare of probiotics , it ’s undecipherable how exactly they affect our gut microbiomes , and influence our overall wellness .
In the new study , research worker recruit seven pairs of identical distaff twins and gave them two servings of yogurt a day for seven workweek . The yoghurt had five melodic phrase of live bacteria .
" The musical theme of using counterpart is a prissy one , " Lynch pronounce . " To some extent , it can standardise genetic and environmental factors that could have an affect on the result . "
The researchers analyzed stool sample distribution from the woman throughout the study , and found yogurt did n’t transfer the species or genes of the bacterial communities in the woman ’s intestine .
In other words , the bacterium in the yogurt did not seem to colonize the player ' guts . In fact , two weeks after the women stopped eating yogurt , the researchers could not observe any live yogurt bacterium in the stool sample of the majority of the participants .
But the researchers then carried out a similar experiment with mice , and regain important changes in the direction the mice metabolized carbohydrates .
A raw framework
Jun Sun , an assistant prof of medical specialty at the University of Rochester in New York , said the researcher ’s method of using mouse with humanized microbiomes could be useful for future studies , especially those that test the health benefits of yogurts and other fermented Milk River products .
The research provides a nice example to test how the initiation of unlike probiotics affects our gut microbial community , Sun said . [ Are Probiotics Safe ? ]
Lynch said studies like this " are fundamental to understand the possible benefits of microbial subjoining approach . "
The study was published today ( Oct. 26 ) in the journal Science Translational Medicine .
Pass it on : Some eccentric of yogurt may alter the way you break down carbs , but more research is needed to really understand the effects of probiotic flora .
