Ukungezwani okuthile kuyindaba yokunambitha-ngokoqobo. Nge-brunch u-oda i-omelet yemifino enobhekeni we-turkey kuyilapho umngane wakho omkhulu ecela amakhekhe ama-blueberry kanye neyogathi. Kungenzeka ukuthi awukuniki ukudla kwakho umcabango wesibili, kepha awuqapheli ukuthi ziningi kangakanani izinto ezithinta ukuthi unezinyo elimnandi noma elinosawoti futhi ujwayele ukuthanda ukudla okunoshukela noma okubushelelezi.

Amaseli wethu we-gustatory receptor-lokho kuyisayensi okusetshenziselwa ukunambitha ama-buds-ukubona ukunambitheka okuyisisekelo okune: okunoshukela, okunosawoti, okumuncu nokubabayo. Uneziqu ezifihliwe ezingaba ngu-10 000, futhi akuzona zonke ezitholakala olimini lwakho: Ezinye zitholakala ophahleni lomlomo wakho kanti ezinye zisemphinjeni wakho, okuchaza ukuthi kungani umuthi ungathandeki kangaka wehla echosheni.

"I-taste bud ngayinye ine-receptor futhi ixhunywe kuma-neurons wezinzwa adlulisa imininingwane mayelana nokunambitheka okuthile okuyisisekelo ebuchosheni," kusho uJoseph Pinzone, MD, isazi se-endocrinologist kanye noprofesa eDavid Geffen School of Medicine e-UCLA. Futhi nakuba izinhlobo zokunambitha zawo wonke umuntu zifana, azifani.

Ucwaningo lukhombisa ukuthi ikhono lethu lokunambitha liqala esibelethweni. Uketshezi lwe-Amniotic ludlulisa ukunambitheka embungwini, okuzoqala kugwinye ukunambitheka okwehlukene ngamanani ahlukile. Lokhu kuvezwa kokuqala kunamathela kuwe ngemuva kokuzalwa. [Twitha leli qiniso!] "Abanye abantu bazalwa benezinzwa zokunambitha ezizwela kakhulu kuswidi, kanti abanye bazalwa nalawo mafutha azwela kakhulu anosawoti, amuncu, noma ababayo," kusho u-Pinzone.

Izakhi zofuzo ezifaka ikhodi yokunambitha kwakho kanye nama-receptors ephunga wonke adlala indima endleleni ozwela ngayo ekunambitheni. Lapho uzwela kakhulu, maningi amathuba okuba uphakamise ikhala lakho kulokho kunambitheka. Okufanayo kuya kuma-texture. "Noma yikuphi ukuzwa okufana nokuqina noma okubushelelezi kubonakala ngezingcindezi ezithatha ulimi nolwelwesi lomlomo oluxhuma kuma-neurons wezinzwa athumela imiyalezo efana 'nokuthanda' noma 'ukungathandi' ebuchosheni," kusho uPinzone. Ama-receptors amaningi onawo lokho kudla okunoshukela okumnandi, kulapho uzothambekela kakhulu ezintweni ezinjengamantongomane, isinkwa esigaxekile, namakhyubhu eqhwa.

Kepha i-DNA akuyona yonke into; ufunda nokuthanda ukudla okuthile ngokusebenzisa okuhlangenwe nakho kobuntwana. "Lapho sichayeka kunoma yisiphi isikhuthazo esinjengokudla, i-chemistry ebuchosheni bethu iyashintsha ngandlela thile," kusho uPinzone. Uma umkhulu wakho ehlale ekunikeza amaswidi e-butterscotch usemncane futhi uhlobanisa lesi senzo nothando, uthuthukisa ukuxhumana kwemizwa ebuchosheni bakho okuvumela amaswidi-okungukuthi, uthola izinyo elimnandi, kuchaza uPinzone. [Tweet kungani unezinyo elimnandi!] Ochwepheshe bacabanga ukuthi okuphambene nakho kungasebenza futhi, ngakho-ke ukuqhuma okunobuthi bokudla okunobuthi ngemuva kwe-hamburger ephathini lokuzalwa esikoleni samabanga aphansi kungakususa entandokazi yasemuva impilo yakho yonke.

Futhi ngenkathi ukuvezwa okuphindaphindwayo kungakusiza ekutholeni ukunambitheka kwejusi le-beet, cishe awusoze wakwazi ukuguqula kakhulu izintandokazi zakho zokunambitheka njengoba ungeke ukwazi ukuguqula izakhi zakho zofuzo, kusho uLeslie Stein, Ph.D., umqondisi wezokuxhumana kwezesayensi isikhungo seMonell Chemical Senses.

Kepha Kuthiwani Ngoshokoledi?

Eminyakeni eyishumi edlule, abacwaningi baqale ukuhlola ukuthi izintandokazi zokunambitheka zehluka kanjani phakathi kobulili. Kubonakala sengathi abesifazane bangase babe nomngcele ophansi wokunambitheka okumuncu, okusawoti, nokubabayo-mhlawumbe ngenxa yokuzwa kwethu iphunga elingcono-futhi lokho kungachaza ukuthi kungani abesifazane bevame ukubika amaswidi othando noshokoledi ngaphezu kwamadoda.

Kepha usuyazi ukuthi ama-hormone ahlangana nezifiso zakho-izikhathi ezithile zenyanga, akekho ongalokotha ame phakathi kwakho nobhasikidi wesinkwa! "Ezikhathini ezahlukahlukene zomjikelezo wowesifazane wokuya esikhathini, ama-hormone akho abangela ukuthi izinhlayiya ezithile zokunambitha zizwele kakhulu noma kancane," kusho uFlorence Comite, M.D., isazi sokusebenza kokugcina kwezindalo eNew York City. Izinguquko ekusebenzeni kwengcindezi yakho nasekucindezelekeni kwakho nakho kungafaka ushintsho kuzakhi zakho zofuzo, bese uvule noma ucishe ama-buds wokunambitha athanda usawoti noma uswidi, uyanezela.
