“Kuwonjezera kwa Konjac glucomannan (KGM) kumawoneka ngati njira yofunikira kwambiri yochepetsera kudzimbidwa, ndipo njira yake ingakhale yowonjezerera kusiyanasiyana ndi kugwira ntchito kwa tizilombo toyambitsa matenda m'matumbo,” analemba asayansi ochokera ku Southwest University ku China mu European Journal of Nutrition. “Zotsatirazi zikuthandizira kwambiri kuthekera kwa ulusi wazakudya pochiza matenda a m'matumbo ndikuwongolera thanzi la m'matumbo, makamaka mwa othamanga.”
Akuti kudzimbidwa kumakhudza akuluakulu okwana 20%, ndipo vutoli limakhala lofala kwambiri pakati pa othamanga.
Malinga ndi nkhani yatsopanoyi, kuchita masewera olimbitsa thupi kwambiri kungachepetse kuyenda kwa magazi kupita m'mimba, motero kuchepetsa kuyenda kwake. Zakudya zokhala ndi mapuloteni ambiri komanso ulusi wochepa zingapangitsenso kuti kuyenda kwa m'matumbo kukhale kovuta, ndipo kutaya madzi m'thupi kungapangitse zinthu kukhala zovuta kwambiri.
Izi zapangitsa ofufuza ena kufufuza ngati ulusi wosungunuka m'zakudya, monga konjac glucomannan (KGM), ungawongolere zizindikiro za kudzimbidwa. Kafukufuku wina akusonyeza kuti KGM ikhoza kukweza kuchuluka kwa madzi m'chimbudzi, kuwongolera kapangidwe ka tizilombo toyambitsa matenda m'matumbo, komanso kulimbikitsa kuyenda kwa matumbo.
"Komabe, deta yachipatala ikadali yochepa mwa anthu, makamaka pakati pa othamanga apamwamba," asayansiwo adalemba.
Kuyesa kwatsopano kumeneku kochitidwa mwachisawawa komanso mosasankhana, kunakhudza othamanga 48 apamwamba a taekwondo omwe anali ndi vuto la kudzimbidwa. Othamangawo anagawidwa mwachisawawa m'magulu awiri: gulu limodzi linalandira placebo (magalamu 3 a maltodextrin tsiku lililonse), pomwe gulu lina linalandira KGM (magalamu 3 patsiku) kwa milungu isanu ndi itatu.
Zotsatira zake zasonyeza kuti poyerekeza ndi placebo, njira zingapo zoyezera kudzimbidwa zinasintha kwambiri, kuphatikizapo kuwunika kwa wodwala zizindikiro za kudzimbidwa (PAC-SYM), kuwunika kwa wodwala khalidwe la moyo wa kudzimbidwa (PAC-QoL), kuchuluka kwa kayendedwe ka matumbo (BMF), ndi index ya ntchito ya matumbo (BFI).
Kusanthula kwa microbiome kunawonetsa kuti KGM inawonjezera kuchuluka kwa α-diversity ndi relative relative kwa mitundu yosiyanasiyana, kuphatikizapo *Lactobacillus*, *Bacteroides*, ndi *Phascolarctobacterium*. Mosiyana ndi zimenezi, kuchuluka kwa *Alistipes* ndi *Desulfovibrio* kunachepa.
Zotsatira zake zinasonyeza kuti kusintha kwa ma microbiota m'matumbo kumagwirizana kwambiri ndi kusintha kwa zizindikiro za kudzimbidwa. Kusanthula kwina kunawonetsa kusintha kwa njira zingapo zochizira kagayidwe kachakudya, makamaka zomwe zimakhudzana ndi biotin biosynthesis ndi kuchepetsa nitrate.
Ofufuzawo anati: “Malinga ndi zomwe tikudziwa, uwu ndi kafukufuku woyamba mwa othamanga a anthu kusonyeza kuti KGM imatha kuchepetsa zizindikiro zokhudzana ndi kudzimbidwa mwa kusintha kapangidwe ka microbiota m'matumbo. Zotsatirazi zikusonyeza kuti kusintha kwa microbiota m'matumbo kungakhale njira yofunika kwambiri yomwe ulusi wazakudya umathandizira pa ntchito ya m'mimba.”
Iwo anamaliza ndi kuti: “Zotsatirazi zimapereka umboni wokwanira wosonyeza kuti kugwiritsa ntchito ulusi wowonjezera m'zakudya kumathandiza pochiza kudzimbidwa ndipo zikusonyeza kuti ndi njira yabwino yochiritsira matenda osagwiritsa ntchito mankhwala kwa othamanga omwe ali ndi vuto la m'mimba.”

Creatine yakhala gawo lofunika kwambiri pamasewera kuyambira m'ma 1990, ndipo imagwiritsidwa ntchito kwambiri popititsa patsogolo magwiridwe antchito a minofu ndi kapangidwe ka thupi panthawi yophunzitsa ndi mpikisano. Komabe, zotsatira za creatine pa othamanga a masewera ankhondo omwe amafunika kukhala ndi kalasi inayake yolemera sizikudziwika bwino.
Kusanthula kwatsopano kukuwonetsa kuti omenyera nkhondo apamwamba amatha kupititsa patsogolo luso lawo la masewera mwa kumwa mankhwala owonjezera payokha kapena kuphatikiza.
Kafukufuku waposachedwapa mwa makoswe wapeza kuti glucomannan, chomera chochokera ku Asia chomwe chimapezeka mu konjac, chili ndi phindu pa thanzi la chiwindi.
