Lesi sihloko siwukuhunyushwa okuvela esiNgisini kombiko wesayensi kaSihlalo weKomidi Lodokotela Lokuqaphela Imithi (USA) u-Andrew Nicholson. Usosayensi uqinisekisa ukuthi isifo sikashukela akuwona umusho. Abantu abanalesi sifo bangathuthukisa inkambo yalesi sifo noma baze basiqede ngokuphelele uma beshintshela ekudleni kwe-vegan okuhlanganisa ukudla kwemvelo, okungahluziwe.
U-Andrew Nicholson ubhala ukuthi yena nethimba lososayensi baqhathanisa ukudla okubili: ukudla kwe-vegan okune-fibre yokudla kanye namafutha aphansi nokudla okuvame ukusetshenziswa kakhulu yi-American Diabetes Association (ADA).
“Simeme abantu abanesifo sikashukela esingancike ku-insulin, kanye nabashade nabo kanye nabalingani babo, futhi kwadingeka balandele ukudla okukodwa kokubili izinyanga ezintathu. Ukudla bekuphekwa abapheki, ngakho ababambe iqhaza bavele bashise ukudla ekhaya,” kuphawula uNicholson.
Ukudla kwe-vegan kwenziwa ngemifino, okusanhlamvu, okusanhlamvu nezithelo futhi akuzange kufake izithako ezicolisisiwe ezifana namafutha kabhekilanga, ufulawa kakolweni we-premium kanye ne-pasta eyenziwe ngofulawa we-premium. Amafutha abala amaphesenti angu-10 kuphela ama-kilojoule, kuyilapho ama-carbohydrate ayinkimbinkimbi enza amaphesenti angu-80 amakholori. Baphinde bathola amagremu angama-60-70 wefiber ngosuku. I-cholesterol yayingekho ngokuphelele.
Kubhekwe kuwo womabili amaqembu eza enyuvesi ngemihlangano kabili ngesonto. Lapho kuhlelwa lolu cwaningo, kwaphakama imibuzo eminingana phambi kososayensi. Ingabe abantu abanesifo sikashukela kanye nabalingani babo bazothatha isinqumo sokubamba iqhaza ocwaningweni? Bazokwazi yini ukushintsha indlela abadla ngayo badle ngendlela uhlelo ebatshela ukuthi badle ngayo zingakapheli izinyanga ezintathu? Kungenzeka yini ukuthola abahlinzeki abathembekile abazolungiselela ukudla okune-vegan okukhangayo kanye ne-ADA-prescribed?
“Okokuqala kwalokhu kungabaza kwashabalala ngokushesha okukhulu. Bangaphezu kuka-100 abantu abasabela esikhangisweni esisithumele ephephandabeni ngosuku lokuqala. Abantu bahlanganyela ngentshiseko esifundweni. Omunye wabahlanganyeli wathi: “Ngamangazwa ukusebenza kahle kokudla kwe-vegan kusukela ekuqaleni. Isisindo sami noshukela wami osegazini kwaqala ukwehla ngokushesha,” kubhala uNicholson.
Usosayensi uphawula ngokuqondile ukuthi abanye ababambiqhaza bamangala ngendlela abajwayele ngayo ukudla okuhlolwayo. Omunye wabo waphawula lokhu okulandelayo: “Ukube othile wangitshela emasontweni angu-12 adlule ukuthi nganginganeliseka ngokudla imifino ngokuphelele, ngangingeke ngikukholwe.”
Omunye umhlanganyeli wathatha isikhathi eside ukuzivumelanisa nezimo: “Ekuqaleni, lokhu kudla kwakunzima ukulandela. Kodwa ekugcineni ngehle ngamakhilogremu angu-17. Angisayisebenzisi imithi yesifo sikashukela noma umfutho wegazi ophezulu. Ngakho kwaba nomphumela omuhle kakhulu kimi.”
Abanye baye bathuthukisa ezinye izifo: “Isifuba somoya asisangikhathazi kangako. Angisayiphuzi imishanguzo eminingi yesifuba somoya ngoba ngiphefumula kangcono. Nginomuzwa wokuthi mina, onesifo sikashukela, manje senginamathemba angcono, lokhu kudla kuyangifanela.”
Womabili amaqembu anamathela ngokuqinile ekudleni okunqunyiwe. Kodwa ukudla kwe-vegan kubonise izinzuzo. Ushukela wegazi osheshayo wawuphansi ngamaphesenti angama-59 eqenjini lokudla kwe-vegan kuneqembu le-ADA. Izilwane ezidliwayo zazidinga imithi emincane yokulawula ushukela wegazi, futhi iqembu le-ADA lalidinga inani lemithi elifanayo nangaphambili. Ama-vegans athatha imithi emincane, kodwa isifo sawo sasilawulwa kangcono. Iqembu le-ADA lalahlekelwa isilinganiso samakhilogremu angu-8 esisindo, kuyilapho ama-vegan alahlekelwa cishe ngamakhilogremu angu-16. Ama-Vegans nawo ayenamazinga aphansi e-cholesterol kuneqembu le-ADA.
Isifo sikashukela singadala umonakalo omkhulu ezinso, futhi ngenxa yalokho, amaprotheni akhishwa emchameni. Ezinye izifundo zibe nenani eliphezulu lamaprotheni emchameni ekuqaleni kocwaningo, futhi lokhu akuzange kube ngcono ekupheleni kocwaningo ezigulini ezidla ukudla kwe-ADA. Ngaphezu kwalokho, abanye babo ngemva kwamasonto angu-12 baqala ukulahlekelwa amaprotheni amaningi nakakhulu. Ngaleso sikhathi, iziguli ekudleni kwe-vegan zaqala ukudlulisa amaprotheni amancane kakhulu emcinini kunangaphambili. Amaphesenti angamashumi ayisishiyagalolunye abahlanganyeli bocwaningo abanesifo sikashukela sohlobo lwe-90 abalandela i-vegan, ukudla okunamafutha aphansi futhi bahamba ngezinyawo, ngamabhayisikili, noma abavocavoca umzimba bakwazi ukuphuma emithini yangaphakathi esikhathini esingaphansi kwenyanga. Amaphesenti angu-2 eziguli ezathatha i-insulin ayeka ukuyidinga.
Ocwaningweni olwenziwa nguDkt. Andrew Nicholson, ushukela wegazi wawuqashwe ezigulini eziyisikhombisa ezinesifo sikashukela sohlobo 2 ezazidla ukudla okuqinile, okunamafutha amancane amasonto ayi-12.
Ngokuphambene, uqhathanise amazinga kashukela egazini nalabo abane abanesifo sikashukela ababemiselwe ukudla okungokwesiko okunamafutha aphansi e-ADA. Abanesifo sikashukela abalandela ukudla kwe-vegan babone ukwehla kukashukela wegazi ngamaphesenti angama-28, kanti labo ababelandela ukudla okunamafutha aphansi kwe-ADA babona ukwehla kukashukela wegazi ngamaphesenti ayi-12. Iqembu le-vegan lilahlekelwe isilinganiso samakhilogremu angu-16 ngesisindo somzimba, kanti labo abaseqenjini lokudla kwendabuko balahlekelwa ngaphezu kwamaphawundi angu-8.
Ngaphezu kwalokho, izifundo ezimbalwa ezivela eqenjini le-vegan zikwazile ukuyeka ngokuphelele noma ngokwengxenye ukuphuza imithi ngesikhathi socwaningo, kuyilapho kungekho nesisodwa eqenjini lendabuko.
Ulwazi oluvela emithonjeni evulekile
