Ngaba ukhe uzive ngathi uyenza yonke into ukutya ukutya okucocekileyo, ukuzivocavoca, ukuvala ii-z-kodwa awungekhe usinciphise isikali? I-Evolution lolona tshaba lwakho olukhulu lokuncipha kobunzima, kodwa ngoku unganako ukulodlula.

Kwisifundo esitsha esipapashwe kwiphephancwadi Unyango lweMolekyuli, Iqela labaphandi abavela kwiYunivesithi yase-Iowa kunye ne-Iowa City VA Medical Centre bavelise uhlobo lonyango lwekhemikhali olugqithise ukuxhathisa kwemizimba yethu ekunciphiseni ubunzima bomzimba kwaye lwenze ukuba izihlunu zethu zitshise amandla ngakumbi, kwanakwizinga eliphantsi lokuzilolonga. Ezi ziphumo zinokuthi zibonelele abantu ngeendlela ezizezinye zokufumana ukwehla okukhulu nokungaguquguqukiyo kobunzima ngaphandle kwamathafa adimazayo adibana nawo ngoku. (Ngaphezulu, jonga iNgcebiso nge-7 yoBunzima bokuThoba uMzimba.)

Ukuze siqonde ngokupheleleyo, kufuneka sibuyele umva kwizigidi zeminyaka eyadlulayo. Khawube nalo mfanekiso-ngqondweni: kufuneka uzingele kwaye uqokelele umhlaba wonke ukuze ufumane ukutya ukuze uphile. Umsebenzi onzima ngokwasemzimbeni, kwaye ungahamba iintsuku ngaphandle kwempumelelo. Imizimba yethu ifumene iindlela zokusebenzisa amandla kancinci. Njengabantu, siye savela ukuze sibe zizidalwa ezisebenza ngokumangalisayo.

Nangona kunjalo, kumaxesha anamhlanje (ngaphandle kokuba ukwilizwe elingaphuhliswanga kakhulu), ukutya akukho kuyo yonke indawo, kukwabiza kancinci. Kwaye imizimba yethu ayikaqhelani nenyaniso yokuba sihamba kancinci kwaye sitya kakhulu. Xa sizama ukwehlisa iipounds, imizimba yethu ibuyela kwinto eyazi ngcono: ukonga amandla kunye nokubambelela kubunzima ukuze singafi. Yindlela yokusinda eyaphuhlayo ukuthintela ukufa yindlala.

Ngokwendalo, oku kuxhathisa ekulahlekeni kobunzima kuyabakhathaza abantu abadla kancinci kodwa bangaboni lahleko. Oku kungoyiswa ngokwandisa umsebenzi wokuzilolongela ukutshisa iikhalori ezininzi, kodwa kunzima kakhulu ukuzilolonga ngokwaneleyo ukuze ulahlekelwe sisixa esikhulu sobunzima-kwaye, ewe, abanye abantu abanako ukwandisa umsebenzi wabo ngokulula ngenxa yeminye imida yezempilo. (Kodwa, isayensi ibonakalisile ukuba ukuHamba yeyona nto iphambili kubomi obude.)

Abaphengululi uSiva Koganti, uZhiyong Zhu, kunye noDenice Hodgson-Zingman bazimisele ukubona ukuba bangaziguqula na iitafile zabo kwindaleko. Kuphononongo, batofa izihlunu zomlenze weempuku ukonga amandla emisipha ukugcina amandla. Ukuphendula, iimpuku ezijoyiweyo zitshise iikhalori ezininzi xa bezisebenza, kwanakwinqanaba eliphantsi lomsebenzi, kuneempuku ezingakhange zifumane unyango olufanayo. Eli nqanaba lomsebenzi linokuthelekiswa nezinto ezenziwa ngabantu yonke imihla kubandakanya nokunxiba, umsebenzi wasekhaya olula, ukuthenga-izinto eziqhelekileyo zemihla ngemihla. (Kwaye ujonge la maqhinga ama-9 okulahleka kwesisindo osele usenza.)

"Iziphumo zethu zibonisa ukuba le ndlela ingasetyenziselwa ukunceda ukunciphisa umzimba," kusho umbhali-mbhali uDenice Hodgson-Zingman, MD, UI unjingalwazi onxulumene nonyango lwangaphakathi. "Ngenxa yokuba sijamelene nobhubhane wokutyeba kakhulu onxulunyaniswa nenani leengxaki ezinxulumene nezempilo, amacebo amatsha anje ngala siwacebisayo anganefuthe elikhulu kwimpilo nakwintlalo-ntle yabantu."

Kwaye nangona uHodgson-Zingman ephawula ukuba isicwangciso esicetywayo akufuneki sithathe indawo yokuzivocavoca, sinokukunceda ukuqala inkqubo yokulahleka kwesisindo kwabaninzi.

Abaphandi basafuna ukujongana nemiba emininzi ebalulekileyo efana nokuba isiphumo sihlala ixesha elingakanani, zingaphi kwaye zeziphi izihlunu ezona zitofwayo, kwaye ukuba kukho naziphi na ixesha elide eliphantsi kunyango. Kodwa, ukuba obu buchule buye baqinisekiswa ngakumbi kwaye bacokiswa, bunokufumaneka kubantu abazama ukunciphisa umzimba. "Sinombono wokuba abantu bazokwazi ukufumana inaliti ezithi gqolo zemisipha yemilenze yabo, edibene nokutya kunye nomsebenzi oqhelekileyo ofanelekileyo kwizakhono zabo, ezinokubanceda ukuba bafezekise iinjongo zabo zokwehla kobunzima," utshilo uHodgson-Zingman.

Okwangoku, kukho izinto ezilula onokuzenza ukogqitha indaleko. Ngenye, tshintsha inkqubo yakho yokusebenza. "Olu pho nonongo luhambelana ngokuthe ngqo neentlobo ezahlukeneyo," utshilo uMichele S. Olson, PhD, unjingalwazi wenzululwazi yezomthambo kwiYunivesithi yaseAuburn, eMontgomery, "Shintsha iintshukumo ozenzayo, thatha umdlalo omtsha, funda izakhono ezitsha, okanye wenze into enamandla. . Kufuneka ugcine izihlunu zakho ziqikelela ukuze utshise iikhalori ezininzi, ngakumbi ukuba unamathele kwiipounds ezi-5 zokugqibela, "utsho. (Zama ezi Ndlela zi-6 zokuQhuba nangayiphi na iminyaka.)

Kodwa sukugcina nje izihlunu zakho ziqikelela; cela umngeni nengqondo yakho, nawe. "Ukufunda into entsha kulungile kubuchopho bethu," utshilo u-Olson. "Udala iindlela ezintsha ze-neural nanini na xa ufunda into entsha kwaye ingqondo yethu isebenzisa iipesenti ezingama-80 zokunikezelwa kwe-glucose imihla ngemihla, ngoko uya kutshisa amandla amaninzi ngaloo ndlela." Ayifumani lula kunoko!
