Pass more gas

Nice NPR story on how passing gas is a good sign that your microbiome is doing it’s job.  And that’s a good thing with wide-ranging health benefits:

So all this got us wondering: Could passing gas, in some instances, be a sign that our gut microbes are busy keeping us healthy?

Absolutely, says Purna Kashyap, a gastroenterologist at the Mayo Clinic in Rochester, Minn.

“Eating foods that cause gas is the only way for the microbes in the gut to get nutrients,” he says. “If we didn’t feed them carbohydrates, it would be harder for them to live in our gut.”

And we need to keep these colon-dwelling critters content, Kashyap says. When they gobble up food — and create gas — they also make molecules that boost the immune system, protect the lining of the intestine and prevent infections…  [emphasis mine]

All these microbes are gas-making fools. They eat up unused food in your large intestine, like fiber and other carbohydrates we don’t digest, and churn out a bunch of gases as waste.

But that’s not all they make. They also produce a slew of molecules (called short chain fatty acids) that may promote the growth of other beneficial bacteria and archaea.

And the more fiber you feed these friendly inhabitants, the more types of species appear, studies have found. This bump in microbial diversity has been linked to a slimmer waistline.

“Undigested carbohydrates allow the whole ecosystem to thrive and flourish,” Kashyap says.

As for me, I’m busy passing gas and eagerly awaiting the results of my very own gut microbiome.
