How much farting is normal?

How much do you think normal people actually fart in a day? — Maybe five. 5 ml a day. 5 ml a day? I don't know. Is that a lot? There was a study, the investigation of normal flatulence production in healthy volunteers. They inserted a rectal tube up people's bottom. — Okay. Uh just to show you this it was about this much up the bum. They connect this bit to then a bag. So I guess at the end of the day they were just carrying around this balloon full of farts. Exactly. God bless these volunteers. — Let me show you the results. Oh my god, I wasn't even close. 1,500 ml for that guy lady? 1. 5 L. No way. What? For me um what was most fascinating was the amount of variation. The amount you fart is influenced by what you eat, but also by the strains of bacteria living in your gut, your microbiome. A recent study tried to get some inside info on this ecosystem by having people swallow this smart pill, a capsule equipped with sensors. We'll discuss what they learned about gut health with the paper's author at How Town Science Paper Book Club.
