Khansara ya m'matumbo yafalikira! Izi zimachitika chifukwa cha kuchepa pang'onopang'ono komanso kuwola kwa zotsalira za nyama m'matumbo. Odya zamasamba samadwala matenda otere. Anthu ambiri odya nyama amakhulupirira kuti nyama ndi yokhayo imene imakhala ndi mapuloteni. Komabe, khalidwe la puloteniyi ndi lochepa kwambiri, losayenera kuti anthu adye, chifukwa lilibe kuphatikiza koyenera kwa amino acid ndi mapuloteni omangamanga.
Kafukufuku akusonyeza kuti anthu ambiri a ku America amapeza mapuloteni owirikiza kasanu kuposa amene amafunikira. Ndizodziwika bwino zachipatala kuti mapuloteni owonjezera ndi owopsa. Choyamba, chifukwa uric acid, yomwe imapangidwa panthawi ya chakudya cha mapuloteni, imaukira impso, ndikuwononga maselo a impso otchedwa nephrons. Matendawa amatchedwa nephritis; muzu wa zochitika zake ndi odzaza impso. Muli mapuloteni ambiri athanzi musupuni imodzi ya tofu kapena soya kuposa momwe amaperekera nyama!
Kodi munaonapo zimene zimachitikira nyama imene yakhala padzuwa kwa masiku atatu? Nyamayo imatha kukhala m’matumbo ofunda kwa masiku osachepera anayi mpaka itagayidwa. Imanama ndikudikirira nthawi yake. Monga lamulo, imakhalapo kwa nthawi yayitali - kuyambira masiku angapo mpaka miyezi ingapo. Madokotala nthawi zonse amawona nyama m'matumbo a anthu omwe adadya zamasamba zaka zambiri zapitazo, zomwe zimasonyeza kuti nyama imakhala yosagawanika kwa nthawi yaitali. Nthawi zina nyama imapezeka m'matumbo a zamasamba omwe ali ndi zaka makumi awiri!
Odya zamasamba ena amati amakhuta kwambiri akamadya. Chifukwa chake ndi chakuti matupi a ketone (zinthu zogayitsa puloteni) amachepa kwambiri akagayidwa. Kwa ambiri, matupi a ketone amayambitsa nseru pang'ono komanso kuchepa kwa chidwi.
Ngakhale kuti thupi limafuna chakudya chochuluka, zokometserazo zimanyansidwa. Uwu ndiye ngozi yazakudya zodziwika bwino zokhala ndi mapuloteni. Ma ketoni okwera modabwitsa amatchedwa ketosis ndipo amalumikizidwa ndi kupondereza kwa njala yachilengedwe, kulephera kwa chikhumbo chofuna kudya. Kuonjezera apo, pamene mulingo wa matupi a ketoni m’mwazi wakwera kwambiri, umayambitsa kutulutsa okosijeni kwa mwazi kotchedwa acidosis.
Akambuku ndi mikango imene imadya nyama ndi kukhala bwino mmenemo imakhala ndi asidi amphamvu m’chigayo chawo. Asidi athu a hydrochloric alibe mphamvu zokwanira kugaya nyama kwathunthu. Kuonjezera apo, matumbo awo ndi otalika mamita asanu, pamene matumbo aumunthu amakhala otalika nthawi zambiri - pafupifupi mamita makumi awiri.
