Ibyiza ku mara ku bantu bakuze nabyo bishobora kuba byiza ku bwonko bwabo. Ubushakashatsi bw’impanga bwagaragaje ko poroteyine ya buri munsi n’inyongera za prebiotics byongera ubushobozi bwo kwibuka ku bantu barengeje imyaka 60.
Ibisubizo by'ubu bushakashatsi, byasohotse mu ntangiriro z'umwaka ushize, birashishikaje gutekereza, cyane cyane ko ibizamini bimwe byo kwibuka no kwiga byakoreshejwe mu gupima ibimenyetso bya mbere by'indwara ya Alzheimer.
Ubu bushakashatsi bwakozwe ku buryo bubiri butagaragara bwakorewe ku miti ibiri ihendutse ikomoka ku bimera iboneka muri farumasi hirya no hino ku isi.
Prebiotics ni ibintu bidasya neza bifasha mu gukangura microflora yo mu mara. Ubwoko bumwe bw'inyongera ni inulin, fibre ikomoka kuri fructan. Ubundi ni fructooligosaccharides (FOS), karubohidrati ikomoka ku bimera ikunze gukoreshwa nk'uburyohe karemano burimo karori nke.
Kugira ngo bapime ingaruka z'izi nyongeramusaruro ku bwonko bushaje, abashakashatsi bo muri King's College London bashatse impanga 36 zifite imyaka 60 kuzamura.
Buri tsinda ry’impanga ryagabanyijwemo amatsinda abiri mu buryo butunguranye: itsinda rimwe ryafataga ifu ya poroteyine irimo prebiotics buri munsi, naho irindi tsinda rigafata ifu ya poroteyine irimo placebo buri munsi.
Nyuma y'amezi atatu, ku bipimo byo mu mutwe, impanga zitari zizi ko inuline cyangwa fructooligosaccharide zifata zagize ingaruka nziza.
Byongeye kandi, kurya fibre buri munsi byafitanye isano n'impinduka nto mu mikorobe y'impanga. Urugero, impanga zifata inulin cyangwa fructooligosaccharides zari zifite umubare munini wa bifidobacteria nziza.
Ubushakashatsi bwakozwe ku mbeba bwagaragaje ko bifidobacteria ishobora kugabanya ubumuga bwo gutekereza binyuze mu guhindura isano iri hagati y’amara n’ubwonko.
“Twishimiye kubona izi mpinduka mu byumweru 12 gusa. Ibi bigira ingaruka zikomeye mu kunoza ubuzima bw'ubwonko no kwibuka mu bantu bakuze,” ibi ni ibyatangajwe na Mary N. Lockley, umushakashatsi mu by’abageze mu zabukuru muri King's College London, ubwo ibyavuye mu bushakashatsi byatangazwaga muri Werurwe 2024.
"Guhishura amabanga y'umutima n'ubwonko bishobora gutuma abantu babaho ubuzima bwiza kandi burambye."
Ishuri Rikuru rya King's College rifite ikigo kinini cyane mu Bwongereza gishinzwe kwandika impanga z'abantu bakuru, kandi ubushakashatsi ku mpanga ni ingenzi mu gusobanukirwa ingaruka z'uturemangingo n'ibidukikije ku buzima bw'abantu.
Ubushakashatsi bwakozwe mbere ku mbeba bwagaragaje ko inyongeramusaruro nyinshi nka inulin na fructooligosaccharides zishobora "kugaburira" mikorobe zo mu mara, bigatuma bagiteri "nziza" zikura neza.
Bagiteri zimwe na zimwe zagaragaye ko zifitanye isano no kunoza imikorere y'ubwonko mu mbeba no mu bantu.
Ibimenyetso bikomeje kwiyongera bigaragaza isano iri hagati y’amara n’ubwonko. Impuguke zimwe ubu zemeza ibi byavuye muri ubu bushakashatsi, ndetse zivuga ko amara ari "ubwonko bwa kabiri" bw’umubiri.
Ubushakashatsi buherutse gukorwa ku mpanga bwakorewe muri King's College London bwerekana ko kurya "ibiryo bimwe na bimwe byongera ubwonko" bishobora kuba uburyo bwiza bwo kuvura ubumuga bwo mu mutwe.
Nubwo imiti ikoreshwa mu gutera imiti ishobora kunoza imikorere y’ubwonko ku bantu bakuze, nko kwibuka no kwihuta mu mikorere y’umubiri, nta nyungu zikomeye zigaragara ku mikorere y’umubiri.
Nubwo inulin na fructooligosaccharides ari ibintu by'ingenzi mu kubungabunga ubuzima bw'imitsi n'amagufwa, kugabanuka kw'imitsi ntibyarushijeho kuba byiza ku bana b'impanga bakuze bafata inyunganiramirire irimo fibre nyinshi.
Claire Stevens, inzobere mu by’abageze mu zabukuru muri King's College London, yagize ati: “Izi fibre z’ibimera zihendutse kandi zigurishwa ku giciro gito zishobora gufasha abantu benshi muri ibi bihe by’ibibazo by’ubukungu. Ziri mu mutekano kandi ziraboneka byoroshye.”
“Inshingano yacu ikurikiraho ni ukureba niba izi ngaruka zishobora gukomeza kubaho mu gihe kirekire no mu baturage benshi.”
Abenshi mu mpanga muri ubu bushakashatsi bari abakobwa. Nubwo abashakashatsi bahinduye ibyavuye mu bushakashatsi bakurikije itandukaniro ry’igitsina, bemeye kandi ko hari aho bashingiye ku guhitamo impanga za KCL.
Mu yandi magambo, abagore bafite amahirwe menshi yo kurwara indwara ya Alzheimer, kandi ubushakashatsi nk'ubu bushyigikira igitekerezo gishya cy'uko kugabanuka k'ubushobozi bwo gutekereza atari indwara y'ubwonko buri gihe kandi ko bishobora no kuba bifitanye isano n'ibintu biturutse hanze.
Amara afitanye isano ya hafi n'imikorere myinshi y'umubiri, harimo n'iy'ubudahangarwa bw'umubiri n'iy'imitsi yo hagati. Kongeramo imiti igabanya ubukana bw'indwara zimwe na zimwe na zimwe zishobora guterwa n'imiti igabanya ubukana bw'indwara zitandukanye bishobora kuvura indwara zitandukanye.
