Through storing wholesome poop if you find yourself more youthful after which donating it again to your self — a procedure they name autologous fecal microbiota transplantation (FMT) — you may be able to push back a few of these sicknesses related to growing old, the scientists mentioned.
“We predict that autologous FMT [stool samples collected from the host at a younger and healthier age] could also be a extra tough healing option to advertise wholesome growing old of the host than heterologous FMT [stool samples collected from an unrelated young and healthy donor],” Liu added.
Many stool banks have already got opened international, basically to retailer wholesome fecal samples so they are able to be to be had to sufferers with C. difficile, researchers famous. About part 1,000,000 other folks in america come down with C. difficile each and every 12 months, and about 29,000 die from the malicious program.
Alternatively, those amenities collect samples taken from donors and passes them alongside to others in want; they do not usually retailer person samples for that donor’s personal long term use.
The brand new paper envisions a long term the place everybody retail outlets away their very own fecal samples in anticipation of “rewilding” their intestine micro organism when they’re older.

“Whilst you transplant intestine micro organism from a more youthful model of your self to an older model of your self, do the micro organism make you more youthful, or do the micro organism themselves turn into older to slot in together with your current microbiome?” mentioned Khanna, who used to be now not concerned with the opinion piece. “We do not know if that has been confirmed to opposite the growing old micro organism or now not.”
The speculation additionally raises a large number of logistical problems.
Storing stool samples for many years will require dear freezers that would get as chilly as -214 levels Fahrenheit, Liu predicts — now not one thing to be had to the common Joe.
“It is a humorous factor to consider, each and every individual having a poop financial institution of their basement freezer, however that would not be the suitable factor to do,” Khanna mentioned. “Stool banking isn’t a DIY proposition.”
Stool banks additionally would wish a large number of freezer house, and will require a large number of power to run the ones freezers, Liu added. It is going to be a dear proposition.
“We don’t wait for that every one folks in our society are keen to pay the price,” Liu mentioned. “Growing an inexpensive trade fashion and business plan would unquestionably require the joint pressure of marketers and scientists.”
