Ososayensi eStanford University eCalifornia bafundile ukuthi ukudla okuthile okujwayelekile kungadala ama-spikes ushukela kubantu abaphilile. Uma unaka lezi ziqephu, ungavimbela ukukhula kwesifo sikashukela kanye nezinye izinkinga zalo.
Isici esihlukile sesifo sikashukela ushukela wegazi ongejwayelekile. Izindlela ezimbili zisetshenziselwa ukukala: bathatha isampula yegazi elisheshayo futhi bathola inani le-glucose esegazini ngaleso sikhathi esithile, noma bahlole i-glycated hemoglobin, ekhombisa inani eliphakeme le-glucose egazini ezinyangeni ezintathu ezedlule.
Naphezu kokusetshenziswa kabanzi kwalezi zindlela zokuhlaziya, akukho neyodwa yazo ayikhombisi ukuguquguquka kushukela wegazi usuku lonke. Ngakho-ke, ososayensi abaholwa nguprofesa wezakhi zofuzo uMichael Schneider banquma ukukala le pharamitha kubantu abathathwa njengabaphilile. Sifunde izinguquko emazingeni kashukela ngemuva kokudla nokuthi bahluke kanjani kubantu abahlukahlukene abadla okufanayo ngokulinganayo.
Izinhlobo ezintathu kashukela wegazi ziyashintsha
Lolu cwaningo lwalubandakanya abantu abadala abangama-57 abaneminyaka engaba ngu-50, okwathi ngemuva kokuhlolwa okujwayelekile bekungenjalo kutholakale ukuthi unesifo sikashukela.
Kulokhu kuhlolwa, amadivaysi amasha aphathekayo abizwa ngokuthi uhlelo lokuqapha okuqhubekayo kwe-glucose egazini asetshenziswa ukuze angakwazi ukukhipha ababambiqhaza ezimweni zabo nakwindlela yabo yempilo ejwayelekile. Ukuphikiswa kwe-insulin yomzimba wonke nokukhiqizwa kwe-insulin nakho kwahlolwa.
Ngokwemiphumela yocwaningo, bonke ababambe iqhaza bahlukaniswa ngama-glucotypes amathathu ngokuya ngamaphethini ngokusho ukuthi amazinga kashukela wegazi lawo ashintshe phakathi nosuku.
Abantu abazinga likashukela lahlala licishe lingaguquki phakathi nosuku bangena eqenjini elibizwa nge- “low variability gluotype”, kanye namaqembu “aphakathi ngokulingana kwe-gluotype” kanye namaqembu “ashiwo ukwahluka kwe-gluotype” aqanjwa ngokomgomo ofanayo.
Ngokwalokho okutholwe ososayensi, ukwephula umthetho wokulawula ushukela wegazi kuvame kakhulu futhi kunamandla kakhulu kunokucabanga kwangaphambilini, futhi kubhekwa kubantu abathathwa njengabaphilile ngokwamazinga ajwayelekile asetshenziswa kumkhuba wamanje.
I-glucose ezingeni le-prediabetes nesifo sikashukela
Ngokulandelayo, ososayensi bathola ukuthi abantu bama-glucotypes ahlukahlukene basabela kanjani ekudleni okufanayo. Ababambiqhaza banikezwe izindlela ezintathu ezijwayelekile zokudla kwasekuseni kwaseMelika: amashidi ommbila obisini, isinkwa nebhotela lamantongomane ne-protein bar.
Ukusabela komuntu ngamunye obambe iqhaza emikhiqizweni efanayo bekuhlukile, okufakazela ukuthi umzimba wabantu abahlukahlukene ubona ukudla okufanayo ngezindlela ezihlukile.
Ngaphezu kwalokho, kwaziwa ukuthi Ukudla okujwayelekile njengama-cornflake kubangela ama-spikes amakhulu ushukela kubantu abaningi.
"Samangala ukubona ukuthi abantu bavame kangakanani ukubheka ukuthi bangabantu abaphilile babe namazinga kashukela ekhuphuka aze afike ezingeni likashukela ngisho nesifo sikashukela. Manje sifuna ukuthola ukuthi yini ebangela okunye kwalokhu kweqa nokuthi bangawenza kanjani ushukela wabo ubejwayelekile," kusho uMichael Schneider.
Ocwaningweni lwabo olulandelayo, ososayensi bazozama ukuthola ukuthi yiziphi izindima zomzimba womuntu ezidlala kumazinga we-glucose okhubazekile: izakhi zofuzo, ukwakheka kwezikhumba ezincanyana kanye nama-macro, imisebenzi yamanyikwe, isibindi nezitho zokugaya ukudla.
Becabanga ukuthi abantu abane-glucotype yokuhlukahluka okuveziwe esikhathini esizayo kungenzeka kakhulu ukuba bahlakulele isifo sikashukela, ososayensi bazosebenza ukudala izincomo zokuvikela lesi sifo se-metabolic kubantu abanjalo.
