People Carries A Few Hundred Types Of Bacteria

People Carries A Few Hundred Types Of Bacteria.
If you were to thrash from vegetarianism to meat-eating, or vice-versa, chances are the formula of your gut bacteria would also undergo a big change, a altered study suggests. The research, published Dec 11, 2013 in the annual Nature, showed that the number and kinds of bacteria - and even the way the bacteria behaved - changed within a daytime of switching from a normal diet to eating either animal- or plant-based foods exclusively. "Not only were there changes in the plenteousness of different bacteria, but there were changes in the kinds of genes that they were expressing and their activity," said swot author Lawrence David, an assistant professor at the Institute for Genome Sciences and Policy at Duke University.

Trillions of bacteria last in each person's gut. They're thought to play a impersonation in digestion, immunity and possibly even body weight. The study suggests that this bacterial community and its genes - called the microbiome - are extraordinarily limber and capable of responding swiftly to whatever is coming its way. "The strip microbiome is potentially quite sensitive to what we eat. And it is receptive on time scales shorter than had previously been thought, however, that it's hard to rag out exactly what that might mean for human health.

Another expert agreed. "It's nice to have some solid fact now that these types of significant changes in diet can impact the gut microflora in a significant way," said Jeffrey Cirillo, a professor of microbial and molecular pathogenesis at the Texas Aandamp;M Health Science Center College of Medicine in Bryan, Texas. "That's very trim to see, and it's very rapid. It's surprising how smart the changes can occur".

Cirillo said it was also intriguing how close to the microbiome seemed to recover. The workroom found that gut bacteria were back to business as usual about a day after people stopped eating the experimental diet. For the study, researchers recruited six men and four women between the ages of 21 and 33. For the prime four days of the study, they ate their usual diets.

For the next five days, they switched to eating either all plant-based or all animal-based foods. They then went back to their sane eating habits before switching to the other abstain pattern. The animal-based intake resulted in the biggest changes to gut bacteria. It spurred the cultivation of 22 species of bacteria, while only three bacterial species became more excrescent in the plant-based diet.

The researchers don't fully understand what the shifts mean, but some made sense. For example, several types of bacteria that became more widespread with the animal-based diet are good at resisting bile acids. The liver makes bile to ease break down fat. Another kidney of bacteria, which became more common in the plant-based diet, is thought to be sensitive to fiber intake. The researchers speculated that the bacterial shifts might detail why fatty diets have been linked to diseases like Crohn's and ulcerative colitis as explained here. More studies are needed, however, before they can foretell for sure.
