Cishe amadoda ayizigidi ezimbili e-US aphila nomdlavuza wendlala yesinye, kodwa kungcono kunokubulawa umdlavuza wendlala yesinye, akunjalo? Ukutholwa kwesifo kusenesikhathi kunikeza wonke amathuba okuqinisekisa ukwelashwa. Kodwa lapho umdlavuza usuqala ukusabalala, amathuba ayancipha kakhulu. Ososayensi baseHarvard bacwaninga amadoda angaphezu kwenkulungwane anomdlavuza wendlala yesinye futhi bawalandela iminyaka eminingana ukuze babone ukuthi kukhona yini ekudleni kwabo okuhlotshaniswa nokubuya komdlavuza, njengama-metastases amathambo.
Uma kuqhathaniswa namadoda angawadli amaqanda, amadoda adla ngisho ngaphansi kweqanda elilodwa ngosuku ayenamathuba aphindwe kabili okuba nomdlavuza wendlala yesinye. Izinto zazimbi nakakhulu kulabo abadla inyama yenkukhu kanye nesikhumba, izingozi zabo zanda izikhathi ezingu-4. Abacwaningi bakholelwa ukuthi lokhu kungase kube ngenxa yokuqukethwe okuphezulu kwama-carcinogens (i-heterocyclic amines) emisipha yenkukhu ne-turkey, uma kuqhathaniswa nezinye izinhlobo zenyama.
Kodwa kuthiwani ngamaqanda? Kungani ukudla iqanda elilodwa ngisho nangaphansi kokukodwa ngosuku kuyiphinda kabili ingozi yomdlavuza? Abacwaningi baseHarvard basikisela ukuthi i-choline etholakala emaqandeni ingase ikhulise ukuvuvukala.
Amaqanda angumthombo ogxile kakhulu futhi omningi we-choline ekudleni kwaseMelika, futhi angase andise ingozi yokuqala umdlavuza, usakazeke, futhi ufe.
Olunye ucwaningo lwe-Harvard, olunesihloko esithi "Umphumela We-Choline Ekufeni Komdlavuza Wendlala Yendlala Yendlala Yesinye," wathola ukuthi ukudla okuphezulu kwe-choline kwandisa ingozi yokufa ngama-70%. Olunye ucwaningo lwakamuva lubonise ukuthi amadoda anomdlavuza wendlala yesinye futhi adla amaqanda amabili nengxenye noma ngaphezulu ngesonto noma iqanda njalo ezinsukwini ezintathu ayenokwanda okungama-81% kwengozi yokufa.
Ithimba labacwaningi baseCleveland Clinic lazama ukuphakela abantu amaqanda abilisiwe esikhundleni se-steak. Njengoba babesola, laba bantu, njengabadla inyama ebomvu, bahlaselwa isifo sohlangothi, isifo senhliziyo nokufa.
Kuyaxaka ukuthi imboni empeleni iziqhayisa ngokuqukethwe kwe-choline emaqanda. Ngesikhathi esifanayo, izikhulu zikwazi kahle ukuxhumana kwayo nokuthuthukiswa komdlavuza.
