Ngaba awukwazi ukuyeka ukutya ukutya okungenamsoco?

Kwabanye abantu, ukutya nje i-cupcake yetshokolethi okanye i-chip enye ephuma kwisikhwama akunakwenzeka. Nangona kunjalo, ngakumbi ukutya okutyayo yonke imihla, kokukhona uya kufuna ukulungiswa kweswekile, ngokophando olutsha.
Izazinzulu zicinga ukuba ukuthanda ukutya okungafunekiyo kunye nokukhotyokiswa ziziyobisi kuyafana kunokuba umntu enokucinga.
Abaphandi kwiZiko loPhando lweScripps eFlorida babonise okokuqala ukuba ukunyanzeliswa kokutya kakhulu kubangela utshintsho olufanayo kwindlela yokuziphatha kunye nokusebenza kwengqondo njengekhoboka leziyobisi.
"Ezi ziphumo ziqinisekisa oko thina kunye nabanye abaninzi esikukrokreleyo - ukuba ukutya okungenamsoco kubangela iimpendulo ezinjengomlutha kwingqondo kwaye kunokukhokelela ekutyebeni," utsho umbhali okhokelayo uPaul Kenny, unjingalwazi wezonyango ze-molekyuli kwiziko loPhando lweScripps.
Ukufumanisa oyena nobangela wokukhotyokiswa kokutya, uKenny nogxa wakhe uPaul Johnson bavavanya indlela ezitya ngayo iimpuku. Abaphandi bahlula iigundane zibe ngamaqela amathathu: Elinye iqela lafumana ukutya okunomsoco okuqhelekileyo kwemifuno; iqela lesibini lafumana ukutya okunamafutha, ukutya okunekhalori ephezulu - ukulingana komntu kokuphatha njenge-bacon kunye ne-cheesecake - kwaye iqela lesithathu lifumene i-chow enempilo, ngaphandle kokufikelela okungenamkhawulo kokutya okungenasiphelo kwiyure enye ngosuku ngalunye.
i iqela bafumene izilwanyana ezivezwe kukutya okungenamsoco imini yonke baba ngabatya kakhulu, besitya iikhalori eziphindwe kabini kuneempuku ezitye ukutya okunempilo, kwaye zaqala ukugcwala kwiiveki nje ezimbalwa. Umkhabi kukuba iimpuku ezityebileyo ziqhubekile zisitya ukutya okungafunekiyo ngokugqithisileyo naxa ukwenjenjalo kuya kubangela ukothuka kombane ezinyaweni zeempuku.
UKenny uthi: “Olu hlobo lwesinyanzelo luyinto kanye esiyibona kumakhoboka eziyobisi.
Iimpuku ezinofikelelo olulinganiselweyo ekutyeni okungenazondlo zaye zaba ngabantu abatya kakhulu, besitya zonke iikhalori zabo kwifestile yeyure enye yokutya.
Nangona kunjalo, ezi mpuku azizange zityebe, nto leyo ebonisa ukuba ukutyeba kunokunxulunyaniswa ngakumbi nokunyanzeliswa, kungekhona ukuzitya, ukutya, amanqaku kaKenny.
Emva koko, abaphandi bafuna ukubona ukuba zeziphi iinguqu ze-neurological ezenzeka kwiingqondo zeegundane ezityebileyo.
Bagxile kwi-brain receptor, ebizwa ngokuba yi-dopamine eboniswe ukuba idlala indima ephambili kubukhoboka beziyobisi. I-receptor isebenza ngokubopha i-dopamine, ikhemikhali ekhutshwe kwingqondo ngexesha lokuzonwabisa, njengesondo, okanye ukusetyenziswa kokutya okanye iziyobisi.
Abaphandi bafumanise ukuba ukutya ukutya okungenamsoco kubangele umkhukula we-dopamine engqondweni. Xa iziko lolonwabo lempuku liye lavuseleleka kakhulu nge-dopamine, ingqondo yayo yaqala ukuziqhelanisa ngokunciphisa umsebenzi we-receptors, utshilo uKenny. Njengoko ezi ndawo zolonwabo ziye zancipha ukusabela, impuku yakhawuleza yakhula imikhwa enyanzelekileyo ukunqanda ukurhoxa, isitya izixa ezikhulu zokutya de ityebe.
Abaphandi baye benza ezinye iimpuku ukuba zibe ne-receptors ezimbalwa kwaye zondla ukutya okungapheliyo. Ibhingo! Izilwanyana zaba zizityebi ngokugqithisileyo phantse ngobusuku.
“Oku kunokuthetha ukuba abantu abazalwa benee-receptors ezimbalwa kunokwenzeka ukuba babe ngamakhoboka okutya okanye iziyobisi,” utshilo uKenny.
Nangona iqela lingakhange licinge indlela yokuphelisa ukukhotyokiswa kokutya, uKenny ucebisa ukuba ukuqonda indlela yokulutha ngokweenkcukacha ngakumbi kuya kunceda ukuvelisa iindlela zonyango zokutyeba.
“Ngethemba, ngenye imini siya kukwazi ukuzilungisa ngokufanelekileyo ezi ndlela zokukhobokisa,” utshilo uKenny.
