UFructose ubizwa nangokuthi ushukela wezithelo, ngoba le monosaccharide itholakala ngamanani amakhulu amajikijolo nezithelo. Umuthi lo umnandi kakhulu kunokucolisiswa okujwayelekile, uba ngumkhiqizo obaluleke kakhulu ekuphekeni.
Sekuyiminyaka eminingi ososayensi bexoxa ngobungozi nezinzuzo ze-fructose, kunamaqiniso angenakuphikwa ongafunda ngawo. Udinga ukwazi ukuthi iziguli ezinesifo sikashukela zinconywa ukusebenzisa i-fructose. Uma uyisebenzisa, umzimba awudingi i-insulin, into leyo ayithinti izinga le-glycemia nganoma iyiphi indlela.
Amanye amaseli adonsa ngqo i-fructose, ayiguqula ibe ngama-acid anamafutha, bese iba amaseli amanoni. Ngakho-ke, ushukela wezithelo kufanele udliwe kuphela ngesifo sikashukela sohlobo 1 nokuntuleka kwesisindo somzimba. Njengoba le ndlela yalesi sifo ibhekwa njengeyokuzalwa, i-fructose iyelulekwa ukuba inikezwe iziguli ezingane.
Kodwa-ke, abazali kufanele balawule inani lale nto ekudleni kwengane, uma engenankinga ngezinga le-glycemia, ukugcwala ngokweqile kwe-fructose emzimbeni kuphakamisa ukukhula kwesisindo ngokweqile kanye nokulimazeka kokudla emzimbeni.
Ukuhlelwa kwezingane
Ushukela wemvelo ungumthombo oyinhloko wama-carbohydrate omzimba womntwana okhulayo, asiza ukuthuthuka ngokujwayelekile, alawula ukusebenza kwezitho zangaphakathi nezinhlelo.
Noma iyiphi ingane ithanda kakhulu amaswidi, kepha njengoba izingane zisheshe zikujwayele ukudla okunjalo, ukusetshenziswa kwefrose kufanele kube nomkhawulo. Yebo, uma i-fructose idliwa ngohlobo lwayo lwemvelo, into etholakala ngezindlela zokwenziwa ayifanele.
Izingane ezingaphansi konyaka ubudala nezinsana azinikwanga i-fructose nhlobo; zithola izinto ezidingekayo ekuthuthukisweni okuvamile kwento ngobisi lwebele noma ngobisi oluxubile. Izingane akufanele zinikeze ujusi wezithelo okumnandi, uma kungenjalo ukumuncwa kwama-carbohydrate kuphazamiseka, i-colic yamathumbu iqala, futhi ngabo ukuleqeka nokuqwasha.
I-Fructose ayidingeki enganeni, into ibekelwa ukufakwa ekudleni uma ingane inesifo sikashukela, kuyilapho ihlala ibheka umthamo wansuku zonke. Uma ufaka ngaphezu kwe-0.5 g ye-fructose ngekhilogremu ngayinye yesisindo:
- kusetshenziselwa ukweqisa;
- lesi sifo siyanda kuphela;
- ukuthuthukiswa kwezifo ezihambisanayo kuqala.
Ngaphezu kwalokho, uma ingane encane idla okuningi okungena esikhundleni sikashukela, iba nokungezwani komzimba, i-atopic dermatitis, okunzima ukuyiqeda ngaphandle kokusebenzisa izidakamizwa.
I-fructose ewusizo kakhulu enganeni itholakala ku uju wemvelo nezithelo. I-sweetener ngesimo sempuphu ekudleni kufanele isetshenziswe kuphela uma kunesidingo esiphuthumayo, ngoba ukulawula okuqinile kwama-carbohydrate adliwayo kusiza ukuvimbela ukukhula kwezinkinga zesifo sikashukela kanye nesifo uqobo. Kungcono uma ingane idla izithelo ezintsha namajikijolo. I-fructose emsulwa iyi-carbohydrate engenalutho; ayisebenzi kangako.
Ukusetshenziswa ngokweqile kwe-fructose kungadala ukuphazamiseka engxenyeni yesistimu yezinzwa, izingane ezinjalo azicasuki kakhulu, ziyajabulisa ngokwengeziwe. Ukuziphatha kuba nokuhlanzeka, kwesinye isikhathi kuze kube nolaka.
Izingane zijwayela ukunambitheka okumnandi ngokushesha okukhulu, ziqala ukwenqaba izitsha ngenani elincane lobumnandi, zingafuni ukuphuza amanzi acacile, khetha i-compote noma i-lemonade. Futhi njengoba ukubuyekezwa kwabazali kukhombisa, lokhu yikho kanye okwenzekayo emsebenzini.
Ukulimaza kwe-Fructose
Izinzuzo nokulimazeka kwezingane ze-fructose kumayelana okufanayo. Kuyingozi ezinganeni ukunikeza inombolo engenamkhawulo yemikhiqizo elungiselelwe kufriji, idliwa ngokulingana. Lokhu kubalulekile, njengoba imetabolism yengane ingathikamezeka, kuyilapho isibindi sihlupheka.
Okungabalulekanga kangako inqubo ye-phosphorylation, okuholela ekuhlukanisweni kwe-fructose ku-monosaccharides, okuphenduka ama-triglycerides namafutha acid. Le nqubo iyisidingo sokwandisa inani lezicubu ze-adipose, ukukhuluphala.
Ososayensi bathole ukuthi ama-triglycerides angalandisa inani lama-lipoprotein, abangele i-atherosulinosis yemithambo yegazi. Lesi sifo sibangela nezinkinga ezinkulu. Odokotela banesiqiniseko sokuthi ukusetshenziswa kaningi, kwe-fructose kushukela sikashukela kuhlotshaniswa nokukhula kwe-bowel syndrome.
Ngalesi sifo, izingane zinenkinga yokuqunjelwa kanye nokugaya ukudla, ubuhlungu besisu, ukuqhakaza nokuqothuka nakho kuyenzeka.
Inqubo ye-pathological ayibonakali kahle ekufakweni kwezakhi zomzimba, umzimba wengane uhlushwa ukushoda kakhulu kwamaminerali namavithamini.
Izinzuzo ze-Fructose
Kunezindlela ezimbili zokuthola i-fructose: yemvelo, yezimboni. Umuthi ukhona ngobukhulu bezithelo ezimnandi kanye ne-artichoke yaseJerusalema. Ekhiqizweni, i-fructose ihlukaniswe nama-molecule woshukela, ngoba iyingxenye ye-sucrose. Yomibili le mikhiqizo iyafana, akukho mehluko obalulekile phakathi kwefrose yemvelo neyokufakelwa.
Inzuzo enkulu yento ukuthi i-monosaccharide iwina kaningi uma iqhathaniswa noshukela omhlophe. Ukuthola ubumnandi obufanayo, i-fructose kufanele ithathwe ngesigamu njengoba icolisisiwe.
Kungcono ukunciphisa inani le-fructose kwimenyu, okubangela umkhuba wokudla ukudla okumnandi kakhulu. Njengomphumela, okuqukethwe kwekhalori kokudla kukhuphuka kuphela, kwabanesifo sikashukela kuyingozi empilweni.
Impahla ye-fructose kumele ibizwe ngokuthi minus, ngoba ingane ingavela:
- ukukhuluphala nesifo sikashukela;
- izinkinga zenhliziyo
- isifo se-pancreatic.
Izakhiwo eziwusizo zifaka ukunciphisa ukuncishiswa kwamakhokho nezinye izinqubo ezingathandeki emgodini womlomo.
I-Fructose ayinabungozi enganeni, uma kufanele unake umthamo wento, kubandakanya inani lesithelo esidliwayo.
Nge-sukari mellitus yohlobo lokuqala, abazali kufanele babheke ukuthi izinga le-glycemia enganeni likhuphuka ngokushesha kangakanani ngemuva kokudla ushukela. Umthamo we-insulin ukhethiwe ngokuya ngale nkomba. Njengoba indawo kashukela inoshukela omnandi kunoshukela ocolisisiwe, ingathathelwa indawo kalula ngayo emathosheni nasekulondolozweni.
Lokhu kunobulungiswa uma ingane ingayithandi imizwa ebabayo ye-stevia.
Umbono ka-Eugene Komarovsky
Udokotela wezingane odumile uKomarovsky uqinisekile ukuthi ushukela ne-fructose ngeke kubizwe ngobubi ngokuphelele futhi kukhawulele yonke imikhiqizo. Ama-carbohydrate abalulekile enganeni, ukukhula komzimba, kepha ngesilinganiso esifanele.
Udokotela uthi uma ingane ithola ukudla okuhlanganisiwe, ngakho-ke akudingekile ukuyinika ukudla okunoshukela. Uma enqaba amanzi noma i-kefir ethambile, imikhiqizo enjalo ngeke ilimaze ukuhlangana nama-purees wezithelo noma izithelo ezomisiwe, kungcono kakhulu kune-fructose futhi ikakhulukazi ushukela omhlophe.
Ezinganeni ezineminyaka engaphezulu konyaka ezinempilo ejwayelekile kanye nomsebenzi, ukudla okumnandi kungafakwa ekudleni, kudliwa ekuseni. Noma kunjalo, kugcizelelwa iqiniso lokuthi abazali ngokuvamile banxephezela ukunganakwa ngamaswidi. Uma amaswidi ethengwa esikhundleni sokuchitha isikhathi esisebenzayo sindawonye, okokuqala kudingeka ushintshe isimo ngaphakathi emndenini, futhi ungafaki ingane efrijini nokudla okumnandi okufanayo.
Kwividiyo ekulesi sihloko, uDkt Komarovsky ukhuluma nge-fructose.
