Uyazi ukuthi unyaka ngamunye abantu abangaba ngu-200 000 babona udokotela maqondana nezinkinga ezihlobene nomqondo wabo wokunambitha? E-United States, kunezinhlobo ezahlukene zokuthi abantu banamandla kangakanani okukwazi ukuthanda izinto. Ama-25% wabantu abahlangenwe nakho awunambitha, kanti ama-50% kuphela ama-tasters ajwayelekile. Lokho kushiya amanye ama-25% wabantu abaningi abangahle bahlukaniswe ngokuthi "ama-supertasters".
Ngokuvamile sithola izinhlobo ezingu-4 zokuthandwa, kodwa ochwepheshe baphikisana ngokuthinta ama-5:
- elimnandi
- umuncu
- usawoti
- okubabayo
- umami
I-5 th ukunambitheka, i-umami, yizwi lesiJapane elifana nelanga elimnandi noma elimnandi. Empeleni ihlotshaniswa nokunambitheka kwe-glutamate futhi kufana nokunambitheka komhluzi. Leli flavour kuthiwa lifaka impendulo yomzwelo.
Ukuzizwa Kokusebenza Kanjani?
Okuthandayo esikubonayo kuyindlela yokusabela kwamakhemikhali amabili okubandakanya kokubili umlomo nomphimbo (ukunambitha) kanye nephunga lethu (iphunga). Sizalelwa ngama-buddha angama-10 000 atholakalayo olimini lwethu, uphahla lomlomo, kanye nasemikhanda yethu. I-sali idlala indima ebalulekile ekuthuthiseni izinto ezithandwayo esizibona emakhakheni ethu okunambitheka. Ihlumela ngalinye elimnandi linamaseli angaba ngu-10-50 anesibopho sokuqala isenzo sokunambitha futhi sigcwaliswa njalo ngezinsuku ezingu-7 kuya kwezingu-10. Ngokwemvelo siqala ukulahlekelwa lawa maqabunga ezinambitheka ezineminyaka engama-50 kuya kwengu-60 ubudala.
Inzwa yethu yokunambitheka iqala ngephunga noma iphunga elizungezile elikhuthaza izinzwa endaweni encane ephezulu ekhaleni. Iphunga elimnandi, elimuncu, noma elimnandi livuselela ubuchopho futhi lithinte ukunambitheka kwangempela kokudla esikudlayo. Ukuzwa kwethu kokunambitheka kuyaqhubeka njengokudla esikudlayo ukuxuba ngamathe ukuze kusebenze amafleji enambitheka akhona ngolimi lwethu, uphahla lomlomo wethu, nasemqaleni.
Kodwa ukunambitheka okungaphezu nje kokuhlanganiswa kokunambitheka (ukugcoba) nokuphunga (okufakiwe) njengoba kuvame ukukholelwa. Inzwa jikelele yenambitheka ivela ekuhlanganiseni kwezinzwa ezikhethekile zokunambitheka nokuphunga kanye neminye impendulo eyaziwa ngokuthi umqondo ovamile wezoketshezi.
Umqondo ovamile wamakhemikhali ungabangela phezu kwendawo yomlomo, umphimbo, impumu kanye namehlo ensimbi. Ngenkathi uhlelo lubuhlungu bemvelo kanye ne-receptor yokushisa okwakhiwe ukuze kusize ukuvikela umzimba, libuye linendima ekuhlinzekeni ukuzwa okunambitheka noma okunamandla ukunambitheka okunjengokuthi: i-capsaicin evuthayo ye-pepper ensili noma ukunambitheka okumnandi kwesikhumba. Ngenkathi ulimi lwethu nekhala zethu zithumela ukunambitheka okuqondile ebuchosheni, umqondo ovamile wezoketshezi awukona ukuzwa ukunambitheka, kepha usinikeza ikhwalithi ephazamisa isipiliyoni sethu ngokudla okunambithekayo.
Izinganekwane Mayelana Nomqondo Wokudla
Kwake bekholelwa ukuthi izindawo ezithile zolimi zinezinhlobonhlobo zokunambitheka okumnandi ezithinta izinzwa zomuntu ngamunye. Lokhu akukholelwa ukuthi kuyiqiniso njengoba izinzwa ezibhekene nokuthanda izinto ezithile zihlakazekile kuzo zonke izifunda zolimi. Ngenkathi kunezinto ezi-5 ezithandwayo ezikhethekile, kutholakale izinzwa ezintathu ezikhethekile kuphela, ngakho-ke kukholelwa ukuthi inhlanganisela ye-akhawunti yokusebenza ngokuthanda izinto esizibonayo.
Okunye okungaqondakali okuvamile, kuhlobene nokulahlekelwa ukunambitheka . Ukulahlekelwa ukunambitheka akuhlobene neze nokuphazamiseka komlomo, ulimi noma umphimbo. Ukulahlekelwa iphunga noma ezinye izimbangela kungathinta umuzwa wakho wokunambitha. I- otolaryngologist noma omunye udokotela angadinga ukuhlola izinto eziningana ngaphambi kokuthola imbangela yokuguqula izinga lokunambitheka.
Ingabe Ulahlekelwa Inkolelo Yakho Yokudla?
Kunemikhuba nezinkinga eziningi ezingathinta inzwa yakho yonke yenambitha. Abanye ozalelwe nabo, ovezwe njengotshani ugwayi , noma kwenzeka ngenxa yesimo sezokwelapha (isib. Ama- polyp nasal , ukulimala kwekhanda, ukutheleleka kwezindlebe eziphakathi , njll ...).
Funda kabanzi mayelana nesihloko sokulahlekelwa umqondo wakho ukunambitheka kwakho .
