Zomwe zili zabwino kwa m'mimba mwa okalamba zingakhalenso zabwino kwa ubongo wawo. Kafukufuku wodabwitsa wa mapasa adapeza kuti mapuloteni a tsiku ndi tsiku ndi zowonjezera zakudya zomwe zimathandizira kukumbukira bwino anthu azaka zopitilira 60.
Zotsatira za kafukufukuyu, zomwe zinafalitsidwa koyambirira kwa chaka chatha, n’zochititsa chidwi, makamaka poganizira kuti mayeso omwewo a kukumbukira ndi kuphunzira agwiritsidwa ntchito pozindikira zizindikiro zoyambirira za matenda a Alzheimer’s.
Kafukufukuyu wokhudza anthu awiri osadziwa zambiri anakhudza mankhwala awiri otsika mtengo ochokera ku ulusi wochokera ku zomera omwe amapezeka m'mafakitale padziko lonse lapansi.
Ma prebiotic ndi zinthu zosagayidwa zomwe zimathandiza kulimbitsa microflora ya m'mimba. Mtundu umodzi wa zowonjezera zotere ndi inulin, ulusi wa zakudya wochokera ku fructan. Wina ndi fructooligosaccharides (FOS), chakudya chochokera ku zomera chomwe chimagwiritsidwa ntchito kwambiri ngati chotsekemera chachilengedwe chotsika ma calories.
Pofuna kuyesa momwe ma supplements amenewa amakhudzira ubongo wokalamba, ofufuza ochokera ku King's College London adalemba mapasa 36 azaka 60 kapena kuposerapo.
Mapasa awiriwa anagawidwa mwachisawawa m'magulu awiri: gulu limodzi linatenga ufa wa mapuloteni wokhala ndi prebiotics tsiku lililonse, ndipo gulu lina linatenga ufa wa mapuloteni wokhala ndi placebo tsiku lililonse.
Patatha miyezi itatu, pa mayeso okhudza ubongo, mapasa omwe sankadziwa za inulin kapena fructooligosaccharide adayamba kuchita bwino.
Kuphatikiza apo, kudya ulusi tsiku ndi tsiku m'zakudya kunagwirizanitsidwa ndi kusintha pang'ono kwa microbiota ya m'mimba mwa mapasa. Mwachitsanzo, mapasa omwe ankamwa inulin kapena fructooligosaccharides anali ndi mabakiteriya ambiri opindulitsa.
Kafukufuku wochitidwa ndi mbewa wasonyeza kuti bifidobacteria ingachepetse vuto la kuzindikira mwa kusintha kulumikizana pakati pa matumbo ndi ubongo.
"Tikusangalala kuona kusintha kumeneku m'masabata 12 okha. Izi zili ndi tanthauzo lalikulu pakukweza thanzi la ubongo ndi kukumbukira mwa okalamba," adatero Mary N. Lockley, wofufuza za okalamba ku King's College London, pomwe zotsatira za kafukufukuyu zidasindikizidwa mu Marichi 2024.
"Kutsegula zinsinsi za ubongo ndi m'mimba kungathandize anthu kukhala ndi moyo wathanzi komanso wautali."
Koleji ya King's ili ndi malo akuluakulu olembetsera mapasa akuluakulu ku UK, ndipo maphunziro a mapasa ndi ofunikira kwambiri pomvetsetsa momwe majini ndi chilengedwe zimakhudzira thanzi la anthu.
Kafukufuku wakale m'makoswe asonyeza kuti zakudya zowonjezera zokhala ndi ulusi wambiri monga inulin ndi fructooligosaccharides zimatha "kudyetsa" microbiota ya m'matumbo, zomwe zimathandiza mabakiteriya "abwino" kukula.
Mabakiteriya ena agwirizanitsidwanso ndi kusintha kwa magwiridwe antchito a ubongo mwa mbewa ndi anthu.
Umboni wochulukirachulukira ukusonyeza kuti pali kugwirizana kwapakati pa matumbo ndi ubongo. Akatswiri ena tsopano akukhulupirira zomwe zapezekazi, mpaka amatcha matumbowo kuti “ubongo wachiwiri” wa thupi.
Kafukufuku waposachedwa wa mapasa omwe adachitika ku King's College London akusonyeza kuti kudya zakudya zina "zolimbitsa ubongo" kungakhale njira yabwino yochiritsira vuto la kuzindikira.
Ngakhale kuti ma prebiotics angathandize kuti ubongo ugwire bwino ntchito mwa okalamba, monga kukumbukira ndi liwiro la ntchito, sizikuwoneka kuti pali ubwino uliwonse m'thupi.
Ngakhale kuti inulin ndi fructooligosaccharides ndizofunikira kwambiri pakusunga thanzi la minofu ndi mafupa, kuchepa kwa minofu sikunawongoke mwa ana amapasa okalamba omwe adamwa zakudya zowonjezera zokhala ndi ulusi wambiri.
"Ulusi wa zomera wotsika mtengo uwu, womwe umagulitsidwa m'masitolo, ukhoza kupindulitsa anthu osiyanasiyana panthawi yovuta yazachuma. Ndi wotetezeka komanso wopezeka mosavuta," anatero Claire Stevens, katswiri wa okalamba ku King's College London.
"Ntchito yathu yotsatira ndikuwona ngati zotsatirazi zitha kupitilizidwa kwa nthawi yayitali komanso mwa anthu ambiri."
Ambiri mwa mapasa omwe adapezeka mu kafukufukuyu anali akazi. Ngakhale kuti ofufuzawo adasintha zotsatira zake kuti aone kusiyana kwa amuna ndi akazi, adavomerezanso kuti kusankhana mitundu mwina kunalipo m'gulu la mapasa a KCL.
Mwa kuyankhula kwina, akazi ali ndi mwayi waukulu wodwala matenda a Alzheimer's, ndipo maphunziro ngati awa akuchirikiza lingaliro lomwe likubwera lakuti kuchepa kwa chidziwitso si matenda a ubongo nthawi zonse ndipo kungagwirizanenso ndi zinthu zina zakunja.
Matumbo amalumikizana kwambiri ndi machitidwe ambiri a thupi, kuphatikizapo chitetezo chamthupi ndi mitsempha yapakati. Kuwonjezera ma prebiotic ndi ma probiotic ena kungathandize kuchiza matenda osiyanasiyana.
