Uninzi lwabantu luvile malunga nobubi bempilo yesiraphu yengqolowa ephezulu ye-fructose (HFCS) kodwa abanalo ulwazi oluninzi Umahluko phakathi kwe-HFCS kunye nezinye iintlobo zeswekile . Zininzi Izizathu zokuba i-HFCS ayilunganga kwimpilo yakho , kwaye uninzi lwezizathu zokuba ayingoyena nobangela weengxaki ezinxulumene nokukhuluphala.
Imicimbi ejikeleze i-HFCS yile nto iyiyo, isetyenziswa njani, kwaye isetyenziswa kangakanani, zonke ezo zinto zinxulumene neengxaki zempilo ezijamelene ne-United States, kubandakanya nokutyeba kakhulu.
Yintoni isiraphu yengqolowa ephezulu yefructose? Isiraphu yengqolowa, eyi-glucose, inyangwa ngee-enzymes ukuyiguqula ibe yi-fructose. I-fructose ixutywe kunye nesiraphu yengqolowa ecocekileyo, ekhokelela kwiswiti eyi-45 yeepesenti yeswekile kunye neepesenti ezingama-55 ze-fructose. Inkqubo yokwenza iziphumo ze-HFCS ekukhululeni ubudlelwane phakathi kweswekile kunye ne-sucrose, eyenza ukuba ingazinzi ngakumbi, kwaye, kuxhomekeke kubani ocelayo, kunokuba yingozi (nge Imilo ).
Ukonakala kwesiraphu yengqolowa ephezulu ye-fructose
Iswekile rhoqo, okanye iswekile yetafile, eyaziwa ngokuba yi-sucrose, yenziwa ngeepesenti ezingama-50 zeswekile kunye neepesenti ezingama-50 zefructose. Iimolekyuli zeswekile zibotshelelwe ngokuqinileyo. Ii-enzyme kwindawo yokugaya ukutya ziqhekeza i-sucrose ibe yi-glucose kunye ne-fructose, ethi ke ingene emzimbeni. Ngenxa yokuba i-glucose kunye ne-fructose kwi-HFCS ayibophelelwanga, inkqubo yokwetyisa inomsebenzi omncinci ekufuneka iwenze. Oku kunokuvakala kulungile, kodwa kuthetha ukuba bayangena kwigazi ngokukhawuleza, kukhokelela i-fructose ngqo kwisibindi, ukuqala inkqubo ebizwa ngokuba yi-lipogenesis, eyimveliso yamafutha kunye ne-cholesterol. Kungenxa yoko le nto i-HFCS inokubangela iimeko eziphezulu zezifo zesibindi ezinamafutha (nge Iposi likaHuff ).
endaweni yokubhaka i-cocoa
Isiraphu yengqolowa ephezulu ye-fructose sele isetyenzisiwe ixesha elide, ke unokuzibuza ukuba kutheni ngequbuliso ivele yonke indawo njengemveliso engalunganga kwimpilo yakho. Kwaqala ngo-2004 xa abaphandi base-Louisiana State University kunye neDyunivesithi yase North Carolina bapapasha iphepha elichaza ithiyori yokuba i-HFCS inokuba sisizathu sokwanda kokutyeba kakhulu, ekuthiwa sisifo sokutyeba kakhulu. Phakathi kowe-1970 nowe-1990, ukusetyenziswa kwe-HFCS e-United States kunyuke ngeepesenti ezili-1000 (nge Imithombo yeLebhu ). Ewe, iipesenti ezili-1000. Ayisiyo typo. Ubhubhane wokutyeba kakhulu wenzeka ngaxeshanye, ke abaphandi bavavanya ulungelelwaniso phakathi kwezi ziganeko zibini ukufumanisa ukuba ngaba akukho bangela (nge IiNgxelo zabaThengi ).
Iziphumo zomzimba zeHFCS
Esinye isizathu sokuba i-HFCS ichongelwe amanqanaba okutyeba kakhulu kukuba i-fructose ikwenza ulambe. Kukho isifundo esivela kwiYunivesithi yaseJohn Hopkins efumanise ukuba i-fructose ivuselela umdla wokutya. Ngaphandle kokufikelela kwisatiety, abantu bathambekele ekutyeni kakhulu. Ingxaki sesinye isifundo esivela kwi- Ijenali yaseMelika yoNyango lweKlinikhi , ethelekisa uphando kwiziphumo ze-HFCS ukuya kwi- Iziphumo zeswekile yetafile , akafumananga mahluko ubonakalayo kwiziphumo emzimbeni. Zombini ezi zinto azilunganga kuwe, kwaye umzimba uphendula ngokufanayo kuzo zombini ngokubhekisele kwiglucose yegazi, indlala, impendulo ye-insulin, kunye namanqanaba ehomoni alawula ukoneliseka nendlala. Ukucaca, iimpembelelo zazo zombini izinto azibi kwaye zibangela ukutya kakhulu kunye nenqanaba eliphezulu lehomoni.
Kukho inkxalabo yokuba i-HFCS inokubenza abantu bagule. Kwakhona, inyani ikwindawo embindini. Isiraphu yengqolowa ephezulu ye-fructose idityaniswe nezifo ezinje ngesifo seswekile kunye nesifo sentliziyo, kodwa kubalulekile ukujonga ibali liphela. Iingxaki zempilo zibangelwa ngamanqanaba aphezulu kakhulu e-fructose asetyenziswa yonke imihla. UAndrew Weil, umlawuli weYunivesithi yaseArizona kwiziko lonyango oluHlanganisiweyo uthe: 'Ngelixa iglucose inyibilikiswa kwiseli nganye emzimbeni, i-fructose yehla esibindini. Imizimba yethu inomthamo olinganiselweyo wokuphatha i-fructose ngezixa eziphakamileyo kwaye ngoku siyazibona iziphumo ebezingalindelekanga.
Abantu badla malini nge-HFCS?
Xa i-fructose yehla esibindini, yehlisa i-HDL, okanye i-cholesterol elungileyo, kwaye inyuse i-LDL, okanye i-cholesterol embi. I-fructose eninzi inokubangela ukwanda kwe-uric acid, enokubangela ukonakala kwezintso kunye ne-gout. Inokuthintela nemithambo yegazi ekuphumleni, ibangele uxinzelelo lwegazi oluphezulu. Uhlobo olongezelelekileyo esibindini lubangela ukuqokelelana kwamafutha, kwaye kunokukhokelela kwisifo sesibindi esinamafutha, kunye nohlobo lweswekile 2 (nge Unyango lwezempilo ).
Into ebalulekileyo yokuchongwa ngaphandle kwe-HFCS njengonobangela wokutyeba kakhulu kukuba ayisiyi-HFCS ngomntu ngamnye, yingxaki leyo, kodwa ukwanda okukhulu ekusetyenzisweni kweswekile xa iyonke. Isiraphu yengqolowa ephezulu ye-fructose iyenzeka nje ukuba ibe yinxalenye ebalulekileyo yentengiso yeswekile ngenxa yenkxaso-mali karhulumente yombona ekhokelela ekubeni i-HFCS ibe ngexabiso eliphantsi kakhulu kubavelisi abayisebenzisayo njengesithambisi, nangenxa yokuba imnandi kunezinye iintlobo zeswekile, iimfuno ezingaphantsi ezakusetyenziswa, konga abavelisi nangaphezulu.
Impendulo kwintengiso
Isiraphu yengqolowa ephezulu ye-fructose ikwandisa ubomi beshelfini yokutya, kwaye igcina izinto zikhangeleka zintsha, zibonelela abavelisi yenye inzuzo.
Umthamo opheleleyo wezinto ezibuswiti ubangela ingxaki, kwaye i-HFCS iyenzeka ukuba ibe siswiti esityiwa ngeyona mali iphakamileyo, esenza malunga nesinye kwisithathu seswekile esenziweyo e-United States. Uphononongo olupapashwe kwi LezeMpilo Jikelele Uhlobo lwesifo seswekile esifunyenweyo siphezulu ngeepesenti ezingama-20 kumazwe atya ukutya okuninzi okusetyenzisiweyo (nge Inzululwazi mihla le ). I-United States isebenzisa iiponti ezingama-55 ze-HFCS ngomntu ngamnye ngonyaka, iyibeka phezulu kuluhlu. Oku kubandakanya ukutya okungenakucingelwa nje ngokuba 'ziilekese,' ezinje ngesonka, iyogathi, okanye ketchup (nge Impilo Yamadoda ).
umtshato we-giada de laurentiis
Kusenokwenzeka ukuba uyidla kakhulu iswekile kunokuba uqonda, kuba abavelisi bayayintywila kuyo yonke into. Ukutya ngekhe ucinga nokuba uneswekile ine-HFCS, enje ngetomato sauce okanye imifuno enkonkxiweyo.
Umahluko kusetyenziso lweswekile namhlanje
Xa i-HFCS yaqala ukufumana ingqalelo engalunganga, uMbutho weConfiners Association wazama ukulwa noluntu olubi ngeentengiso zabo, apho babanga ukuba i-HFCS ayinazithambiso ezingezizo. Lo ngumzekelo wendlela i-HFCS njengemveliso, kunye nomzi mveliso osemva kwayo, ziluhlobo olunomthunzi. Kuyinyani ukuba i-HFCS ayinazithako zokwenziwa. Nangona kunjalo, iyasetyenzwa kusetyenziswa izinto ezingezizo ezifana ne-glutaraldehyde, into eyenziweyo, ngokwe-U.S. Ukunxibelelana nearhente kuthintela imveliso ekuthiwa yeyendalo. Nangona kunjalo, ukuba iarhente isetyenziselwa ukuveliswa kwe-HFCS, kodwa ingekhoyo ekunxibelelaneni ngqo ne-cornstarch, imveliso evelayo isenokubanga ukuba 'yendalo.' Ngenxa yalo msebenzi ujikeleze, ezinye ii-HFCS zinakho ukubanga ngokusemthethweni izithako ezingezizo (nge IiNgxelo zabaThengi ).
Ookhokho bethu batya malunga neetispuni ezingama-20 zeswekile ngonyaka, xa kuthelekiswa ngoku xa isetyenziswa kakhulu loo nto ngosuku. Ukuthelekisa, i-20-ounce isiselo esinxilisayo, esifana nesoda okanye iziselo zemidlalo, iqulethe iitispuni ezili-17 zeswekile. Oko kuthetha ukuba isiselo esinye silingana neswekile seminyaka xa usithelekisa nokutya kwendalo, okungasetyenziswanga (nge Iposi likaHuff ).
