"Ushukela wemvelo" kungenye yamagama we-fructose (i-levulose, i-hexose), i-carbohydrate, futhi kunokuphikisana njalo ngobungozi noma izinzuzo zesakhiwo.
Odokotela bathi i-fructose inempilo futhi ingasebenza njengento ebambele ushukela yemifino.
Abanye odokotela bathi le carbohydrate iyingozi emzimbeni womuntu. Ngaphandle kokungaboni ngaso linye, ushukela wezithelo namanje awukwazi ukwenza kabi ngokuphelele. Namuhla kuvame ukusetshenziswa ekukhiqizeni ukudla njenge-analogue ye-sweeteners. Ngefomu yayo emsulwa, ushukela wezithelo ungazuzisa ngokuhlanganiswa okulinganiselwe ngezakhi ze-ballast.
Ukwakheka kwamakhemikhali kwalesi carbohydrate yi-monosaccharide eyingxenye ye-sucrose. Uma kuqhathaniswa noshukela ojwayelekile, unambitha izikhathi eziyi-1.5 futhi amahlandla ama-3 amnandi kune-glucose. Imvamisa isetshenziswa ngabantu ababheka impilo kanye nesibalo.
I-Levulosis inenkomba ye-glycemic ephansi, kepha kuthiwa yikhompiyutha yokugaya ukudla kalula. Ungawuthola lo muthi ngendlela engokwemvelo neyokufakelwa. I-levulose yemvelo iqukethe imifino nezithelo.
Kukhiqizwa i-fructose eyenziwe ngamabele nama-beet. Kuthuthukiswe ikakhulukazi ukwenziwa kwefreyimu yokwenziwa eChina naseMelika. I-Levulose isetshenziswa njenge-sweetener emikhiqizweni yabashukela. Ngefomu elihlanganisiwe, abantu abanempilo enhle abanconywa ukuthi bayisebenzise ngenxa yezici eziningi ezifundwe ngabezempilo. Akuwona wonke umzimba okwazi ukubekezelela le-carbohydrate, umuzwa ngamunye ungavela kuwo, lapho ngabe i-fructose kungafanele idliwe. Kuyadingeka kakhulu ezinganeni ukwethula ukudla okuqukethe i-hexose ekudleni, ngoba kungavela ukungezwani komzimba noma ukungezwani komzimba.
Ukuzwisisa inqubo nomphumela kashukela wezithelo emzimbeni, udinga ukwazi ukuthi i-fructose imunwa kanjani. Ukufakwa kwe-fructose kwenzeka ngesibindi. Lapho, i-carbohydrate iyacutshungulwa bese iguqulwa ibe ushukela, bese okusele kuguqulwa kube ngamanoni; akunconywa ukuba ukhuthale ngemikhiqizo equkethe i-hexose.
Lokhu kusongela izinkinga zenhliziyo kanye nokukhuluphala, ngoba i-levulosis iqala ukuthatha indawo ngokwayo emzimbeni wamafutha asele angena emzimbeni womuntu, futhi ngenxa yalokho, aqala ukugcinwa lapho kungadingeki khona.
Ngokungafani ne-sucrose, i-fructose ayakhi cimbi lamakhemikhali, futhi ngenxa yalokho ayiphikisi izicubu zomzimba. Kepha ukulimazeka kwe-monosaccharide akukaze kufakazelwe, futhi imikhiqizo enokuqukethwe iba imbala.
Ukugwema imiphumela emibi ye-fructose kulula uma utadisha izakhiwo zayo nomphumela onawo emzimbeni. Udokotela ohambelayo angasho ngalokhu, imininingwane enjalo ingatholwa ngokuzimela, uma usebenzisa imithombo ekhethekile.
Ukuze umzimba uthole inani lezinto ezinhle, kudingeka udle kahle futhi wazi ukuthi yikuphi ukudla okuqukethe i-fructose. Le carbohydrate ingatholakala ekudleni okuhlukile, hhayi nje kuphela isithelo, kodwa futhi nemifino ingaqukatha fructose.
Ezimweni zezitshalo, okuqukethwe kwe-carbohydrate kwesinye isikhathi kufinyelela kuma-85-90%. Ngokubambisana ne-glucose, i-fructose ingatholakala ezitshalweni, emilonyeni, izithelo, uju lwezinyosi.
Uhlu lwemikhiqizo equkethe ushukela wezithelo:
- Izithelo namajikijolo. Banamavithamini amaningi futhi akukho mafutha. Ngenxa ye-fructose, le mikhiqizo ine ukunambitheka okumnandi. Inani elikhulu kakhulu le-monosaccharide litholakala kuma-apula, amagilebhisi, amaparele, ama-cherries, amawolintshi, ikhabe, ikhabe, ipena, i-sitrobheli, ubhanana, izinsuku kanye nama-sitrobheli.
- Imifino. I-Fructose itholakala kwimifino enjenge-asparagus, i-broccoli, iklabishi, amazambane, upelepele, insiza, izaqathe, u-anyanisi nazo zonke izinhlobo zezinhlamvu. Zama ukufaka imifino ekudleni kwakho kwansuku zonke.
- I-Legumes Ziqukethe inani elikhulu lezinto eziwusizo - i-iron, amaprotheni kanye ne-fiber, ezinye i-legumes zine-fructose, zingatholakala kumantongomane, o-lentini nobhontshisi.
- Ijusi neziphuzo. Ama-Store ama-juices aphezulu kakhulu ku-fructose ngenxa ushukela ovela esithelweni nesithelo se-cocuctose-ecebile yommbila ukuze wenze umkhiqizo ube muncu. Okufanayo kusebenza nakwezinye iziphuzo, ezinjengezithelo, isoda, i-lemonade, iziphuzo ezidakayo, ngoba nazo zengeza isiraphu yommbila.
- Amaqanda. Yize zingenawo ukunambitheka okumnandi, ngaphezu kwamavithamini B4, B12, ama-amino acid, amaprotheni ne-cholesterol, nawo ane-fructose.
Inani elikhulu kakhulu lama-carbohydrate, kufaka phakathi i-fructose, lingatholakala kuju. Kutholakala nesigaxa se-maple, ushukela onsundu nethebula noshukela oluyimpuphu.
Njengoba kushiwo ngaphambili, odokotela abakwazi ukuza nesinqumo esisodwa ngezinzuzo ezingalingani noma ukulimala kwe-fructose yomzimba. Abanye babo bayaqiniseka ukuthi ushukela wezithelo ulusizo kakhulu, ngoba ngosizo lwayo kungenzeka ukuvimba ukuthuthukiswa kwe-plaque kanye ne-caries. Ayigcwali i-pancreas futhi, uma iqhathaniswa noshukela ojwayelekile, imnandi kakhulu, ngenxa yokuthi kungenzeka ukuthi inciphise izingxenye ezidliwayo. Enye ingxenye yabodokotela abathi i-fructose ingadala i-gout kanye nokukhuluphala. Bakwazi ukufika ekuvumelaneni kuphela ngendaba yokuthi uma usebenzisa ukudla okuqukethwe yile monosaccharide ngamanani ajwayelekile, ngokulinganayo, umzimba uzobe usizakala kuphela.
Nsuku zonke, umuntu kufanele adle kusuka kuma-30 kuya kwangama-50 amagremu we-fructose. Abantu abanesifo sikashukela, ukuthatha izidakamizwa ukwehlisa ushukela wegazi noma ukujova i-insulin bavunyelwe ukudla i- fructose ngenani lama-gramu angama-50 ngosuku, ingalungiswa ijamu yezithelo. Lapho upheka le ubilongwe ngokufakwa kwe-fructose, iphunga nokunambitheka kwamajikijolo kuyathuthukiswa.
Umehluko kuphela kusuka ku-jam ushukela ojwayelekile kuzoba umbala olula womkhiqizo osuqediwe. Iresiphi ilula kakhulu. Hlambulula amajikijolo alungiselelwe bese ulungiselela isiraphu namanzi. Ukuze wenze ukuvumelana kube kukhulu, ungangeza i-gelatin. Letha uketshezi ngamathumba. Hlanganisa isiraphu namajikijolo bese upheka imizuzu emi-5 kuye kweli-7 ekushiseni okuphansi kakhulu. I-Fructose ishintsha izakhiwo ngesikhathi sokulashwa okushisa isikhathi eside, ngakho-ke isikhathi sokupheka sincishisiwe.
Ukusetshenziswa ngokweqile kwe-fructose kungaholela ekwakhekeni kwesisindo ngokweqile (ukumuncwa okunciphisiwe kwe-carbohydrate ngesibindi futhi namafutha acids aqala ukugcinwa "endaweni yokugcina"). Elinye iphuzu elingelibi ukwanda kwesifiso sokudla - i-leptin ye-hormone, ebhekene nesifiso sokudla, icindezelwa yi-fructose, ngakho-ke isibonakaliso mayelana nokugcwala komzimba akungeni ebuchosheni.
Kepha ukuntuleka kwe-fructose kuyingozi emzimbeni ngokukhathala kokwethuka, ukulahlekelwa amandla, ukudangala, ukunganaki kanye nokuxaka. Ngakho-ke, kubaluleke kakhulu ukulondolozela ukulinganisela futhi unamathele okujwayelekile ekusetshenzisweni kwemikhiqizo equkethe ushukela wezithelo. Imiphumela emihle ye-levulosa emzimbeni womuntu ifaka ukukhuthaza ukusebenza kobuchopho, amandla, ukuphuculwa kohlelo lwe-endocrine, kanye nokuvimbela ama-caries. Ukuphindwaphindiselwa kokulondolozwa kwamandla kwenzeka ngokushesha futhi akuholeli ekugxumeni okubukhali kushukela wegazi.
Imininingwane nge-fructose inikezwe kuvidiyo ekulesi sihloko.
