Inzululwazi emva kweZinyo lakho elimnandi

Umxholo

• Uphengululo lwe

Umahluko othile ngumbandela wokungcamla-ngokoqobo. Kwi-brunch uyala i-omelet yemifuno kunye ne-turkey bacon ngelixa umhlobo wakho osenyongweni ecela i-blueberry pancakes kunye neyogathi. Mhlawumbi awukucingi okwesibini ukutya kwakho, kodwa awuqondi ukuba zingaphi na izinto ezichaphazelayo nokuba unezinyo eliswiti okanye elinetyuwa kwaye udla ngokuthanda ukutya okurhabaxa okanye okugudileyo.

Iiseli zethu ze-gustatory receptor-yileyo isayensi yolwimi lweencasa zencasa-bona izinto ezine ezisisiseko zokungcamla: eziswiti, ezinetyuwa, ezimuncu, nezikrakra. Unamaqhuma amalunga ne-10,000, kwaye ayizizo zonke ezifumaneka elulwimini lwakho: Ezinye zifumaneka eluphahleni lomlomo wakho kwaye ezinye zisemqaleni wakho, nto leyo echaza ukuba kutheni iyeza lingemnandanga ukuhla.

"I-taste bud nganye ine-receptor kwaye idityaniswe kwii-neurons zemizwa ezihambisa ulwazi malunga nencasa ethile esisiseko kwingqondo," utshilo uJoseph Pinzone, MD, ugqirha we-endocrinologist kunye nonjingalwazi kwiDavid Geffen School of Medicine e-UCLA. Kwaye ngelixa incasa yomntu wonke iyafana, ayifani.

Izifundo zibonisa ukuba amandla ethu okungcamla aqala esibelekweni. Ulwelo lwe-amniotic ludlulisela incasa kusana olungekazalwa, oluya kuthi ekugqibeleni luqale ukuginya incasa ezahlukeneyo ngemilinganiselo eyahlukileyo. Oku kuvezwa kokuqala kunamathela kuwe emva kokuzalwa. [Tweet this fact!] "Abanye abantu bazalwa benencasa ebukhali kakhulu, kodwa abanye bazalwa benetyiwa, ubumuncu okanye ubukrakra," utshilo uPinzone.

Imfuza ekhowudi incasa yakho kunye nevumba lokufumana zonke izinto zidlala indima kwindlela onovakalelo ngayo kukhetho. Okukhona uvakalelo lwakho luphezulu, kokukhona kunokwenzeka ukuba uphakamise impumlo yakho kuloo ncasa. Kuyafana nokuthungwa. "Nayiphi na imvakalelo efana ne-crunchy okanye egudileyo ibonwa ngoxinzelelo lwe-receptors ngolwimi kunye nomgca womlomo odibanisa kwii-neurons ezithumela imiyalezo 'efana' okanye 'engayithandiyo' engqondweni," kusho uPinzone. Ii-receptors ezininzi onazo zokutya okunezinto ezi-crunchy, kokukhona uya kutsalela kwizinto ezinje ngamandongomane, isonka esiqhekezayo, kunye neetyhubhu zomkhenkce.

Kodwa iDNA ayisiyiyo yonke into; Kwakhona ufunda ukuthanda ukutya okuthile ngamava obuntwana. "Xa sibonakaliswe kulo naluphi na uvuselelo olunjengokutya, i-chemistry ebuchosheni bethu iyatshintsha ngandlela thile," utshilo uPinzone. Ukuba utat'omkhulu wayesoloko ekunika iilekese ze-butterscotch xa wawuselula kwaye unxulumanisa esi senzo nothando, uphuhlisa unxibelelwano lwe-neural engqondweni yakho oluthanda iilekese-oko kukuthi, ufumana izinyo elimnandi, uyacacisa uPinzone. [Tweet kutheni unamazinyo amnandi!] Iingcali ziqikelela ukuba okuchaseneyo kunokusebenza nako, ngoko ke ubundlobongela bokutya ityhefu emva kwehambhega kumnyhadala wokuzalwa wesikolo samabanga aphantsi unokukususa kwintandokazi yasemva kwendlu ubomi bakho bonke.

Kwaye ngelixa ukubhengeza okuphindaphindiweyo kunokukunceda ufumane incasa yejusi ye-beet, ngekhe ubenakho ukutshintsha kakhulu izinto ozikhethayo kuba ungekhe uguqule iigene zakho, utshilo uLeslie Stein, Ph.D., umlawuli wezonxibelelwano kwezenzululwazi. iZiko leMonell Chemical Sense Centre.

Kodwa kuthekani ngeTshokholethi?

Kule minyaka ilishumi idlulileyo, abaphandi baqalisile ukuphonononga indlela incasa yokukhetha eyahlukileyo ngayo phakathi kwesini. Kubonakala ngathi abantu basetyhini banokuba nomda osezantsi weencasa ezimuncu, ezinetyuwa, kunye nobukrakra- mhlawumbi ngenxa yokuziva kwethu ngevumba-kwaye oko kungachaza ukuba kutheni abantu basetyhini behlala bexela iilekese zothando kunye netshokholethi kunamadoda.

Kodwa sele uyazi ukuba ukungcola kwamahomoni kunye neminqweno yakho-amaxesha athile enyangeni, akukho mntu unokulinga ukuma phakathi kwakho nengobozi yesonka! UFlorence Comite, M.D., isazi nge-endocrinologist kwisiXeko saseNew York uthi: “Kwiindawo ezahlukahlukeneyo zomjikelo wokuya exesheni kwebhinqa, iincindi zamadlala zakho zibangela ukuba incasa ethile ibe buthathaka ngakumbi okanye kancinane. Utshintsho ekusebenzeni kwe-thyroid yakho kunye noxinzelelo lunokuthi lutshintshe utshintsho kwijene yakho, kwaye uvule okanye ucime i-taste buds ezonwabela ityuwa okanye iswiti, wongeza.
