Izinongo ezitsheni zisiza ukuphila isikhathi eside. Ukudla ukudla okubabayo kuhlotshaniswa nengozi enciphile yokufa ngaphambi kwesikhathi, kuphetha ososayensi. Ngokusho kongoti, lolu daba ludinga olunye ucwaningo.
Lolu cwaningo lubuze abantu abacishe babe ngu-500000 eChina ukuthi badla kangaki ukudla okubabayo. Ababambiqhaza babephakathi kweminyaka engama-30 nengama-79 ubudala ngesikhathi kuqala ucwaningo futhi balandelwa iminyaka engu-7. Ngalesi sikhathi, abantu abangu-20000 XNUMX bafa.
Njengoba kwenzeka, abantu abadla ukudla okubabayo usuku olulodwa noma ezimbili ngesonto babenethuba elingaphansi kwe-10% lokufa ngesikhathi socwaningo uma kuqhathaniswa nabanye. Lo mphumela washicilelwa ngo-Agasti 4 kumagazini i-BMJ.
Ngaphezu kwalokho, abantu abadla ukudla okubabayo izinsuku ezintathu ngeviki noma ngaphezulu babemancane ngo-14% amathuba okuthi bafe kunalabo abadla ukudla okubabayo ngaphansi kokukodwa ngesonto.
Yiqiniso, lokhu bekuwumbono nje, futhi kusesekuseni kakhulu ukusho ukuthi kukhona ubudlelwano obuyimbangela phakathi kokudla okubabayo kanye nokufa okuphansi. Umbhali wocwaningo uLiu Qi, uprofesa osebenza naye e-Harvard School of Public Health eBoston, uthi idatha eyengeziwe iyadingeka phakathi kwezinye izakhamuzi.
Abacwaningi abakatholi ukuthi kungani izinongo zihlotshaniswa nokufa okuphansi. Ucwaningo lwangaphambilini kumaseli ezilwane luphakamise izindlela ezimbalwa ezingenzeka. Isibonelo, ukudla okubabayo kuye kwaboniswa ukunciphisa ukuvuvukala, ukuthuthukisa ukuwohloka kwamafutha omzimba, nokuguqula ukwakheka kwama-bacteria amathumbu.
Abahlanganyeli babuzwa nokuthi yiziphi izinongo abazikhethayo—upelepele omusha, upelepele omisiwe, isoso kachili, noma uwoyela kachili. Phakathi kwabantu ababedla ukudla okubabayo kanye ngesonto, iningi lalikhetha upelepele omusha nowomisiwe.
Okwamanje, ososayensi bakholelwa ukuthi kudingeka kusungulwe ukuthi izinongo zinamandla okuthuthukisa impilo nokunciphisa ukufa, noma uma ziwuphawu lwezinye imikhuba yokudla nezindlela zokuphila.
