Namuhla, inkinga yokukhuluphala isifinyelele izinga eliwumqedazwe. Lokhu akukona nje ukukhuluphala ngokweqile, kodwa ukuxilongwa. Lesi sifo sidala ukuncipha kwesibalo sabantu kodwa siyelapheka ngodokotela abahlukahlukene, okuhlanganisa odokotela abafundela umsebenzi, ongoti bokudla okunomsoco, odokotela benhliziyo, odokotela besifo sofuba kanye nodokotela bengqondo. Cabanga nje uma bekukhona inkinobho ekhethekile ezoqala ukushisa amafutha emzimbeni, futhi inqubo yokulahlekelwa isisindo izohamba ngokushesha? Kubonakala sengathi "inkinobho" enjalo ikhona ngempela.
Ososayensi bathole isifunda ebuchosheni esisebenza “njengokushintsha” ukushisa amafutha ngemva kokudla. Baqaphela indlela umzimba oguqula ngayo amafutha amhlophe, agcina amandla, abe amafutha ansundu, asetshenziselwa ukushisa lawo mandla. Amafutha agcinwa kumaseli akhethekile emzimbeni asiza umzimba ukuba ushise noma ugcine amandla owathola ekudleni.
Abacwaningi bathole ukuthi ngesikhathi sokudla, umzimba usabela ku-insulin ejikelezayo. Khona-ke ubuchopho buthumela izimpawu zokugqugquzela amafutha ukuba ashise ukuze aqale ukusebenzisa amandla. Ngokufanayo, lapho umuntu engadli futhi ebulawa indlala, ubuchopho buthumela iziyalezo kumangqamuzana akhethekile aziwa ngokuthi ama-adipocyte ukuze aguqule amafutha ansundu abe amafutha amhlophe. Lokhu kusiza ukonga amandla lapho abantu bengadli isikhathi eside, futhi kuqinisekisa ukuzinza kwesisindo somzimba. Ngamanye amazwi, ukuzila ukudla akubandakanyi inqubo yokushiswa kwamafutha.
Kuvela ukuthi yonke le nqubo eyinkimbinkimbi ilawulwa indlela ekhethekile ebuchosheni, engafaniswa nokushintshwa. Iyacima noma ngokuya ngokuthi umuntu udlile futhi isiza ukulawula ukusetshenziswa kwamafutha. Kodwa kubantu abakhuluphele, "i-switch" ayisebenzi kahle - ibambeka endaweni "ekuvuliwe". Uma abantu bedla, akucishi futhi awekho amandla amoshayo.
"Kubantu abakhuluphele, lo mshini uhlala usebenza," kusho umbhali wocwaningo uTony Tiganis we-Institute of Biomedicine eMonash University. - Ngenxa yalokho, ukushisa kwamafutha kuvalwe unomphela, futhi izindleko zamandla ziyancipha ngaso sonke isikhathi. Ngakho-ke, lapho umuntu edla, akaboni ukunyuka okulinganayo kwezindleko zamandla, okunomthelela ekuzuzeni isisindo.
Manje ososayensi banethemba lokuthi bangakwazi ukusebenzisa iswishi, bayivale noma bayivule, ukuze basize abantu balawule kangcono inqubo yokushiswa kwamafutha.
“Ukukhuluphala ngesinye sezifo ezinkulu nezihamba phambili emhlabeni jikelele. Ngokokuqala ngqa emlandweni, sibhekene nokuncipha kweminyaka yokuphila ngenxa yokukhuluphala ngokweqile,” kwengeza uTiganis. “Ucwaningo lwethu luveze ukuthi kunendlela ebalulekile eqinisekisa ukusetshenziswa kwamandla. Lapho umshini uphukile, ukhuluphala. Ngokunokwenzeka, singayithuthukisa ukuze sikhuthaze ukusetshenziswa kwamandla nokuncipha kwesisindo kubantu abakhuluphele. Kodwa kusekude lokho.”
