Zvinobatsira mudumbu muvanhu vakuru zvinogonawo kubatsira muuropi hwavo. Ongororo yakaitwa patsva yakaratidza kuti mapuroteni ezuva nezuva uye prebiotic supplementation zvinovandudza mashandiro ekurangarira muvanhu vane makore anopfuura makumi matanhatu.
Zvakabuda muchidzidzo ichi, zvakaburitswa kutanga kwegore rapera, zvinokurudzira kufunga, kunyanya tichifunga kuti bvunzo dzekurangarira nekudzidza dzakashandiswa kuona zviratidzo zvekutanga zvechirwere cheAlzheimer.
Chidzidzo ichi chaisanganisira mishonga miviri isingadhuri, inogadzirwa nemiti inonzi fiber prebiotics inowanikwa muma pharmacy pasi rese.
Ma prebiotics zvinhu zvisingagayike zvinobatsira kukurudzira microflora yemudumbu. Imwe mhando yekuwedzera yakadaro i inulin, fiber yekudya inobva ku fructan. Imwe i fructooligosaccharides (FOS), makabhohaidhiretsi anobva mumiti anowanzo shandiswa sechisikigo chinotapira chine macalorie mashoma.
Kuti vaongorore migumisiro yemishonga iyi pauropi hwekukwegura, vaongorori vekuKing's College London vakatsvaga mapatya makumi matatu nematanhatu ane makore makumi matanhatu zvichikwira.
Mapatya maviri ega ega akakamurwa zvisina tsarukano kuita mapoka maviri: boka rimwe raitora upfu hweprotein hune prebiotics zuva nezuva, uye rimwe boka raitora upfu hweprotein hune placebo zuva nezuva.
Mwedzi mitatu gare gare, pabvunzo dzepfungwa, mapatya akanga asingazivi nezvekudya kwe inulin kana fructooligosaccharide aiwanzoita zviri nani.
Uyezve, kudya fiber zuva nezuva kwaibatanidzwa nekuchinja kudiki mu microbiota yemudumbu remapatya. Semuenzaniso, mapatya aitora inulin kana fructooligosaccharides aive nehuwandu hwakawanda hwemabhakitiriya anobatsira.
Ongororo dzakaitwa mumakonzo dzakaratidza kuti bifidobacteria inogona kuderedza kutadza kuziva nekuchinja hukama huripo pakati pedumbu neuropi.
"Tinofara kuona shanduko idzi mumavhiki gumi nemaviri chete. Izvi zvine zvazvinoreva pakuvandudza hutano hwehuropi nekurangarira muvanhu vakuru," akadaro Mary N. Lockley, muongorori wezvevanhu vakwegura paKing's College London, apo mhedzisiro yechidzidzo ichi yakaburitswa munaKurume 2024.
"Kuvhura zvakavanzika zveuropi nedumbu kunogona kubatsira vanhu kurarama hupenyu hune hutano uye hwakareba."
Koreji yeKing's ine nzvimbo huru muUK yekunyora mazita emapatya evakuru, uye zvidzidzo zvemapatya zvakakosha pakunzwisisa simba remajini nenzvimbo zvakatikomberedza pahutano hwevanhu.
Ongororo dzakaitwa kare mumakonzo dzakaratidza kuti mishonga ine fiber yakawanda yakaita se inulin ne fructooligosaccharides inogona "kudya" microbiota yekoloni, zvichiita kuti mabhakitiriya "akanaka" abudirire.
Mamwe mabhakitiriya akabatanidzwawo nekuvandudzwa kwebasa rekufunga mumakonzo nevanhu.
Humbowo huri kuramba huchikura hunoratidza kuti ura neuropi zviri pedyo. Vamwe nyanzvi vava kugutsikana nezvakawanikwa izvi, vachitoti ura ihwohwo "uropi hwechipiri" hwemuviri.
Ongororo ichangobva kuitwa pamapatya paKing's College London inoratidza kuti kudya zvimwe "zvikafu zvinosimudzira pfungwa" kungave nzira yakanaka yekurapa kukanganisa pfungwa.
Kunyangwe prebiotics ichigona kuvandudza mamwe mabasa ekuziva muvanhu vakuru, akadai sekuyeuka nekukurumidza kwekugadzirisa, zvinoita sekunge hapana zvakanakira zvakakosha mumuviri.
Kunyange zvazvo inulin nefructooligosaccharides zviri zvinhu zvakakosha pakuchengetedza hutano hwemapfupa nemapfupa, kurasikirwa kwemhasuru hakuna kuvandudzika mumapatya akura akatora mishonga ine fiber yakawanda.
"Idzi shinda dzemiti dzisingadhuri, dzinotengeswa kunze kwechitoro chekutengesa dzinogona kubatsira vanhu vakasiyana-siyana munguva dzino dzematambudziko ehupfumi. Dzakachengeteka uye dziri nyore kuwana," akadaro Claire Stevens, chiremba wevana vakwegura paKing's College London.
"Basa redu rinotevera nderekuona kana mhedzisiro iyi ichigona kuchengetedzwa kwenguva yakareba uye muvanhu vakawanda."
Mapatya mazhinji muongororo iyi aive echikadzi. Kunyangwe vaongorori vakagadzirisa zvabuda kuti vaone kusiyana kwepabonde, vakabvumawo kuti kumwe kusarurana kwekusarudza kungave kuripo muboka remapatya reKCL.
Nemamwe mashoko, vakadzi vane mukana mukuru wekuwana chirwere cheAlzheimer, uye zvidzidzo zvakaita seizvi zvinotsigira maonero ari kubuda ekuti kudzikira kwepfungwa hakusi chirwere cheuropi nguva dzose uye kunogonawo kusanganiswa nezvinhu zvekunze.
Utumbo hwakabatana zvakanyanya nehurongwa hwakawanda hwemuviri, kusanganisira immune system ne central nervous systems. Kuwedzera ma prebiotics nema probiotics mugut microbiota kunogona kugadzirira nzira yekurapa zvirwere zvakasiyana-siyana.
