Ukutya kakhulu kunokubuyisela ubuchopho bakho

• Uphengululo lwe

Nokuba sizimisele kangakanani kwiinjongo zethu zempilo, nkqu nabona bazinzileyo phakathi kwethu banetyala lokukhohlisa usuku lokuzinkcinkca ngapha nangapha (hay, akukho hlazo!). Kodwa inyani inyani kwimbono yokuba ukutya kakhulu kube kanye kuyakwenza ukuba uqhubeke nokuzinkcinkca ngefrisi ngeyure yokonwaba ukuya kwi-ODing kwi-froyo kamva ngokuhlwa, ngokutsho kwesifundo esitsha esivela kwiYunivesithi yaseThomas Jefferson ePhiladelphia

Isifundo (esenziwe kwiimpuku, sisafuna ukuphindwa ebantwini), sijonge indlela ukutya kakhulu oku kunefuthe ngayo kwiimvakalelo zethu zokugcwala-okanye, indlela isisu nengqondo ezinxibelelana ngayo. Ngokwesiqhelo, xa sisitya, imizimba yethu (kunye nemizimba yeempuku) ivelisa ihomoni ebizwa ngokuba yi-uroguanylin, ebonisa ukuba ingqondo yethu iyondliwa kwaye idala ukuziva uzele. Kodwa ukutya kakhulu kwenza le ndlela ivalwe.

Abaphandi bafumanise ukuba xa iimpuku zigqityiwe, amathumbu amancinci ayekile ukuvelisa i-uroguanylin ngokupheleleyo. Kwaye ukuvalwa kwenzeka nokuba iimpuku bezityebe kakhulu. Ngamanye amazwi, ukutya kakhulu akunanto yakwenza nendlela osempilweni ngayo ukuqala ngayo-kuko konke malunga nokuba zingaphi iikhalori ozityayo ngexesha elinye. (Kubi kangakanani ukutya ngokuzinkcinkca ngamaxesha athile?)

Ukufumanisa ukuba le ndlela isisu-yengqondo ivalwa njani xa sisebenzisa iikhalori ezininzi, abaphandi bajonga iiseli ezivelisa i-uroguanylin emathunjini amancinci eempuku. Nangona bengakhange bayichaze ngokupheleleyo inkqubo kuphononongo, bacingela ukuba i-endoplasmic reticulum (ER), elawula uninzi lweehomoni zomzimba kwaye inovelwano kuxinzelelo, inokuba netyala. Xa abaphandi banika iimpuku ezigqithileyo imichiza eyaziwayo yokuphelisa uxinzelelo, indlela eyavulwa.

Ngelishwa, asazi ukuba ukutya kuninzi kangakanani. Indawo ngqo apho indlela ekhuthaza ukuzala ivaliwe ayaziwa kwaye inokwahluka ukusuka komnye umntu uye komnye. Eyona nto ibalulekileyo: Ukutya ngokugqithisileyo-nokuba ngamaxesha athile-kunokukubeka emngciphekweni wokuguqula isidlo se- #treatyoself sibe kukuzinkcinkca ngempelaveki.
