Kumashumi eminyaka, isiraphu yengqolowa ene-high-fructose isetyenzisiwe njengeswiti kukutya okucutshungulwayo.

Ngenxa yomxholo wayo we-fructose, uye wagxekwa kanobom ngenxa yeziphumo ebezingalunganga zempilo.

Uninzi lwabantu lubanga ukuba luyingozi ngakumbi kunezinye iilekese ezisekwe kwiswekile.

Eli nqaku lithelekisa isiraphu yengqolowa ene-high-fructose kunye neswekile eqhelekileyo, iphonononga ukuba ingaba mbi kunenye.

Yintoni isiraphu yengqolowa ephezulu-yeFructose?

Isiraphu yengqolowa ephezulu ye-fructose (HFCS) siswiti esimnandi esivela kwisiraphu yengqolowa, eqhutywa kumbona.

Isetyenziselwa ukwenza ukutya okuswitiweyo kunye neziselo ezihlwahlwazayo- ikakhulu eMelika.

Ngokufanayo kwiswekile yesiqhelo yetafile (i-sucrose), inezinto zombini i-fructose kunye ne-glucose.

Yaba siswiti esidumileyo ngasekupheleni kweminyaka yee-1970 xa amaxabiso eswekile rhoqo ayephezulu, ngelixa amaxabiso embona ayephantsi ngenxa yenkxaso-mali karhulumente (1).

Nangona ukusetyenziswa kwayo kuphakamile phakathi kwe-1975 kunye ne-1985, iye yehla kancinci ngenxa yokunyuka kokuthandwa kweswekile yokufakelwa (1).

Isiraphu yengqolowa ene-high-fructose siswiti esekwe kwiswekile, esetyenziselwa ukutya okucutshungulwayo kunye neziselo eUnited States. Njengeswekile eqhelekileyo, ineswekile elula yeswekile kunye nefructose.

Inkqubo yokuvelisa

Isiraphu yengqolowa ephezulu ye-fructose yenziwa ngombona (umbona), oqhele ukwenziwa uhlengahlengiso lwemfuza (GMO).

Ingqolowa iyaqala ukusilwa ukuvelisa isitatshi sengqolowa, emva koko kusetyenzwe ngakumbi ukwenza isiraphu yengqolowa ().

Isiraphu yengqolowa ineswekile eninzi. Ukwenza iswiti kwaye ifane ngokungafaniyo neswekile yetafile yesiqhelo (i-sucrose), enye yeglucose iguqulelwa kwi-fructose isebenzisa ii-enzymes.

Iindidi ezahlukeneyo zesiraphu yengqolowa ye-high-fructose (HFCS) zibonelela ngemilinganiselo eyahlukeneyo ye-fructose.

Umzekelo, ngelixa i-HFCS 90- eyona fomu igxile- ine-90% ye-fructose, uhlobo olusetyenziswa ngokuxhaphakileyo, i-HFCS 55, ine-55% ye-fructose kunye ne-42% yeswekile.

I-HFCS 55 iyafana ne-sucrose (iswekile yetafile eqhelekileyo), eyi-50% ye-fructose kunye ne-50% yeswekile.

Isiraphu yengqolowa ene-high-fructose iveliswa ngesitatshi sengqolowa (yombona), esacocwa ngakumbi ukuvelisa isiraphu. Uhlobo oluqhelekileyo lunomyinge we-fructose-to-glucose ofana neswekile yetafile.

Isiraphu yeMbewu ePhakamileyo yeFructose vs Iswekile yesiqhelo

Kukho umahluko omncinci kuphela phakathi kwe-HFCS 55-lolona hlobo luqhelekileyo lwesiraphu yengqolowa ephezulu-fructose- kunye neswekile eqhelekileyo.

Umahluko omkhulu kukuba isiraphu yengqolowa ene-fructose enamanzi equkethe iipesenti ezingama-24 zamanzi- ngelixa iswekile yetafile yomile kwaye inegranulated.

Ngokubhekisele kulwakhiwo lweekhemikhali, i-fructose kunye neglucose kwisiraphu yengqolowa ene-fructose ephezulu ayibophelelwanga kunye njengakwiswekile yetafile enziwe ngegranus (sucrose).

Endaweni yoko, ziyadada zodwa ecaleni kwelinye.

Lo mahluko awuchaphazeli ixabiso lesondlo okanye iipropathi zempilo.

Kwinkqubo yakho yokwetyisa, iswekile ichithwe yangena kwi-fructose kunye neglucose- isiraphu yengqolowa kunye neswekile ziphela zijongeka ngokufanayo.

Igram yegram, i-HFCS 55 inamazinga aphezulu aphezulu e-fructose kuneswekile eqhelekileyo. Umahluko mncinci kakhulu kwaye awuchaphazeli ngokukodwa umbono wezempilo.

Ewe, ukuba uthelekisa iswekile yetafile rhoqo kunye ne-HFCS 90, ene-90% ye-fructose, iswekile eqhelekileyo inokuba yinto enqwenelekayo, kuba ukusetyenziswa gwenxa kwe-fructose kunokuba yingozi kakhulu.

Nangona kunjalo, i-HFCS 90 kunqabile ukuba isetyenziswe- kwaye emva koko kuphela ngamanani amancinci ngenxa yobumnandi bayo obugqithisileyo ().

Isiraphu yengqolowa ene-high-fructose kunye neswekile yetafile (i-sucrose) iphantse yafana. Umahluko ophambili kukuba iimolekyuli zefructose kunye neglucose ziboshwe kunye kwitafile yeswekile.

Iziphumo kwiMpilo kunye neMetabolism

Esona sizathu siphambili sokuba iiswiti ezisekwe kwiswekile zingenampilo kungenxa yemali enkulu ye-fructose abayinikezelayo.

Isibindi kuphela kwento enokuthi isebenzise i-fructose ngokwexabiso. Xa isibindi sakho sigcwele umthwalo, ijika i-fructose ibe ngamanqatha ().

Amanye ala mafutha anokuhlala esibindini sakho, enegalelo kwisibindi esinamanqatha. Ukusetyenziswa okuphezulu kwe-fructose kukwanxulunyaniswa nokumelana ne-insulin, isifo se-metabolic, ukutyeba kakhulu, kunye nohlobo lweswekile yesi-2 (,,).

Isiraphu yengqolowa ene-high-fructose kunye neswekile eqhelekileyo zinomxube ofanayo we-fructose kunye ne-glucose-ngomlinganiselo we-50: 50.

Ke ngoko, unokulindela ukuba iziphumo zempilo ziyafana kakhulu-eziqinisekisiweyo amatyeli amaninzi.

Xa kuthelekiswa iidosi ezilinganayo zesiraphu yengqolowa ene-high-fructose kunye neswekile eqhelekileyo, uphando lubonisa ukuba akukho mahluko kwiimvakalelo zokugcwala, ukuphendula kwe-insulin, amanqanaba e-leptin, okanye iimpembelelo kubunzima bomzimba (,,, 11).

Ke, iswekile kunye ne-high-fructose ingqolowa yesiraphu iyafana ngokwembono yezempilo.

Izifundo ezininzi zibonisa ukuba iswekile kunye nesiraphu yengqolowa ephezulu eneempembelelo ezifanayo kwimpilo nakwimetabolism. Zombini ziyingozi xa zisetyenziswa kakhulu.

Iswekile eyongeziweyo ayilunganga - Isiqhamo asiyiyo

Nangona i-fructose egqithisileyo evela kwiswekile eyongeziweyo ingenampilo, akufuneki ungakuphephi ukutya iziqhamo.

Iziqhamo kukutya okupheleleyo, kunentabalala yefibre, izakhamzimba, kunye ne-antioxidants. Kunzima kakhulu ukutyisa i-fructose ukuba uyifumana kuphela kwisiqhamo sonke ().

Iziphumo ezingalunganga zempilo ye-fructose isebenza kuphela kwiswekile eyongeziweyo, eqhelekile kwiikhalori ephezulu, ukutya kwaseNtshona.

Nangona iziqhamo ziphakathi kwezona zinto zityebileyo zendalo ze-fructose, zinxulunyaniswa nezibonelelo zezempilo. Iziphumo ezibi zempilo zinxulunyaniswa nokutya kakhulu iswekile eyongeziweyo.

Umgca osezantsi

Eyona ndlela iqhelekileyo yesiraphu yengqolowa ene-fructose ephezulu, i-HFCS 55, iphantse yafana neswekile yetafile eqhelekileyo.

Ubungqina bokucebisa ukuba enye imbi kakhulu kunenye iyasilela.

Ngamanye amagama, zombini zibi ngokulinganayo xa zisetyenziswa kakhulu.
