Kutheni sifuna ukutya okumnandi?

Kutheni sifuna ukutya okumnandi, ngokuqinisekileyo ukutya kuyisidingo esisisiseko sokuphila, kodwa kutheni sihlala sityekele ekutyeni okutyebileyo kwiikhalori kunye namafutha ukutya okumnandi kunye neeswekile, zivela kwiziko leemvakalelo zobuchopho.

Ngokutsho kwe "Daily Mail", izazinzulu ezivela kwiYunivesithi yaseNorth Carolina (UNC) zafumanisa ukuba le ndawo yobuchopho, ebizwa ngokuba yi-amygdala, "ikhanyisa" xa iigundane zinandipha ukutya, kungekhona nje naluphi na uhlobo lokutya, kodwa kwakhona. ezo ziqulethe iikhalori ezininzi.

Izazinzulu zikholelwa ukuba ukufumanisa kwazo kunokubonelela ekujoliswe kuko ekuphuhliseni iyeza lokunciphisa umzimba eliya kutyhafisa umnqweno wokuqhubeka nokutya ukutya okunamafutha, ngaphandle kokuphazamisana nemikhwa efunekayo yokutya rhoqo.

Uphononongo lubonisa ukuba iimvakalelo, okanye ubuncinci amaziko eemvakalelo ebuchotsheni bethu, asiqhubela ukuba sitye ukutya, okungazange kube kuninzi kuyo yonke iminyaka, okukhokelela ekuphuhlisweni kwenkqubo engqondweni esixelela ukuba sifumane ukutya okuninzi njengoko kunokwenzeka, kangangoko sinako.

Iinkqubo zethu ze-metabolic zinenzuzo yokuguqula amafutha esiwadlayo abe ngamandla, ngoko ke (ukusuka kwindawo yokujonga i-evolution) ukutya okunamafutha aphezulu kuyingcamango efanelekileyo.

Uphononongo lugqibe kwelokuba zimbini iindlela zokutya: ukutya okulinganayo ngenjongo yokuphila, kunye nokutya okungaguqukiyo ngenjongo yolonwabo.

Kutshanje, izazinzulu ziye zatshintshela ekugxileni ekutyeni ulonwabo, zaza zafumanisa iprotein ebizwa ngokuba yi-neoseptin, ebonakala isebenza ngakumbi xa iimpuku kunye nabantu besitya ukutya okumnandi, okutyebileyo, okusigcina sisenjenjalo.

Ke, iyeza elithintela le proteni linokunciphisa iminqweno yethu yokutya kakhulu.

Kufuneka kuqatshelwe ukuba izazinzulu ziye zafunda i-amygdala ixesha elide, kwaye zidibanisa neentlungu, ukuxhalaba kunye noloyiko, kodwa iziphumo zamva nje ziqinisekisa ukuba zidibene nezinye izinto, ezifana nokulawula ukutya kwe-metabolic.
