Ngabe zonke ushukela utshwala zikunika uhudo?
Ngabe zonke izinhlobo zezindawo ezifuywayo ezingezwe ekudleni okunempilo?
Namuhla sizokhuluma ngakho. Kuyini ngempela ushukela utshwala? I-Sugar Alcohols yi-polyols evame ukwenziwa kusuka ezinhlobonhlobo zoshukela ohambelana. Isibonelo, ukuncishiswa kwe-xylose kuyinto eyi-xylitol ejwayelekile.
Ngaphezu kwalokho, ama-alcohols oshukela njengamanje asakhiwa yintuthuko anjengokulandelayo:
Glucose → sorbitolol dructose → i-manitol lactose → glucose pucthitol → erythritol sucrose → isodelalt
I-Sorbibibibing ushukela utshwala manje munye wengezo ezingezo ezijwayelekile zokudla "ezisebenzayo". Kungani kungezwa ekudleni? Ngoba inezinzuzo eziningi.
Okokuqala, ukuqina kotshwala bokushisa kwe-acid kukuhle, futhi ukusabela kwe-maillard akulula ukwenzeka ngokushisa, ngakho-ke akubangeli ukulahleka kwezakhi zomzimba kanye nesizukulwane kanye nokuqongelela ama-carcinogens. Okwesibili, ama-alcohols kashukela awasetshenziswa ama-microorganisms emlonyeni wethu, okunciphisa inani le-PH ukukala emlonyeni, ngakho-ke awenzeli amazinyo;
Ngaphezu kwalokho, ama-alcohols kashukela ngeke akhuphule inani likashukela wegazi lomzimba womuntu, kodwa futhi ahlinzeke ngenani elithile lamakhalori, ngakho-ke lingasetshenziswa njenge-sweetener yokudla okunempilo yabantu abanesifo sikashukela.
Kunezinhlobo eziningi zokudla okulula kwama-xylitol kanye nama-dessert emakethe. Ngakho-ke uyabona ukuthi kungani ushukela utshwala buyi-classic "Isengezo sokudla okusebenzayo"?
Kuyiqiniso, ama-alcohols kashukela alungile, kepha ungabi nokuhaha - ama-alcohols amaningi kashukela ajwayele ukuvumelanisa lapho kuthathwa ngemithamo emikhulu.
Maltitol udla uhudo owengeziwe, yimuphi umgomo?
Ngaphambi kokuchaza umgomo, ake siqale sibheke imiphumela ehlanzayo yezimo ezijwayelekile ezivamile (ezisetshenziswayo) zotshwala.
| Ushukela utshwala | Ubumnandi(sucrose = 100) | Isifo sohudo |
| Xylitol | 90-100 | ++ |
| I-Sorbibibittol | 50-60 | ++ |
| Umaneholi | 50-60 | +++ |
| Maltitol | I-80-90 | ++ |
| I-Lactitol | 30-40 | + |

Lapho udla utshwala obunoshukela, abaphulwa phansi nguPepsin, kepha qhubeka ngqo namathumbu. Iningi lotshwala obushukela litholwa kancane emathunjini, elidala ingcindezi ephezulu ye-osmotic, ebangela ingcindezi ye-osmotic yokuqukethwe kwamathumbu ukuba ikhuphuke, bese kuthi amanzi we-mucosal odongeni lwamathumbu angena emgodini wamathumbu, bese umatasa.
Ngasikhathi sinye, ngemuva kokuba utshwala utshwala bungena emathunjini amakhulu, kuzovuswa amagciwane amathumbu ukukhiqiza igesi, ngakho-ke isisu siyofezeka. Kodwa-ke, akuzona zonke izinhlobo zotshwala ezikhiqiza isifo sohudo negesi.
Isibonelo, i-Erythritol, okuwukuphela kwe-zero-calorie ushukela utshwala, inesisindo esincane samangqamuzana futhi kulula ukuyithola, futhi inani elincane kuphela elingena emathunjini amakhulu ukuze livutshwe ama-microorganisms. Umzimba womuntu futhi ngokubekezelela okukhulu kwe-Erythritol, ama-80% e-Erythritol egazini lomuntu, awahlinzeki ngama-enzyme, awanikezi amandla emchameni, ngakho-ke angenziwa nje kubangela uhudo kanye nokugcwala.
Umzimba womuntu unokubekezelela okuphezulu kwe-isomalilt, kanye no-50g ukudla kwansuku zonke ngeke kubangele ukungakhululeki kwesisu. Ngaphezu kwalokho, isomaliltol futhi i-bifidoobacterium enhle kakhulu ye-bifidoobacteration factor, engakhuthaza ukukhula kwe-bifidoobacterium, gcina ibhalansi ye-microocological yepheshana lamathumbu, futhi ilungele impilo.
Ukufingqa, izimbangela eziphambili zohudo kanye nokufutheka okubangelwa ushukela utshwala yilezi: okokuqala, akugciniwe ngama-enzyme abantu kepha kusetshenziswa yi-flora yamathumbu; Okunye ukubekezelela okuphansi komzimba kukho.
Uma ukhetha i-Erythritol ne-isomalitl ekudleni, noma uthuthukise ifomula ukwandisa ukubekezelelana komzimba kushukela wotshwala, unganciphisa kakhulu imiphumela emibi yotshwala.
Yini enye ephuza ushukela? Ingabe kuphephile ngempela?
Abantu abaningi bathanda ukudla okumnandi, kepha ubumnandi busilethela injabulo ngasikhathi sinye, futhi kuletha ukukhuluphala, ukubola kwamazinyo kanye nesifo senhliziyo. Ngakho-ke ukuze kuhlangatshezwane nezidingo ezimbili zokunambitheka nempilo, kwazalwa ushukela.
I-Sugar Storetites yiqembu lezinhlanganisela ezenza ukudla kube mnandi futhi kuphansi kilojoule. Ngaphezu kotshwala obunoshukela, kunezinhlobo zezinye izinhlobo zezindawo ezifuywayo, njenge-licorice, i-stevia, i-monkfruit glycoside, iSoma elimnandi nezinye izithako zoshukela zemvelo; Kanye ne-saccharin, acesulfameae, i-aspartame, i-sucralose, i-cyclamate kanye nezinye izinto zoshukela zokwenziwa. Iziphuzo eziningi emakethe zibhalwe ukuthi "Alukho ushukela, ushukela we-zero", abaningi empeleni basho ukuthi "akukho sucrose, akekho ama-sweence", futhi ngokuvamile engeza ama-sweeteners (esikhundleni sendawo) ukuze aqinisekise ubumnandi. Isibonelo, uhlobo olulodwa lwe-soda luqukethe i-erythritol ne-sucralose.
Esikhathini esithile esidlule, umqondo wokuthi "Alukho ushukela"Futhi"ushukela we-zero"Kwabangela ingxoxo ebanzi kwi-Intanethi, futhi abantu abaningi bangabaza ukuphepha kwalo.
Ungayibeka kanjani? Ubudlelwano phakathi kwezindawo ezinoshukela nempilo kuyinkimbinkimbi. Okokuqala, esikhundleni soshukela semvelo sinomthelela omuhle empilweni yabantu. Njengamanje, ubunzima obukhulu balele ezindlekweni zabo zokukhiqiza kanye nokutholakala kwemithombo yezemvelo.
I-Momordica iqukethe ushukela wemvelo "Momordica glucoside". Ucwaningo luye lwabonisa ukuthi i-Moyoside ingathuthukisa ukusetshenziswa kwe-glucose kanye nokuthathwa kwamafutha, yandisa ukuzwela kwe-insulin, okulindeleke ukuthi kuthuthukiswe isifo sikashukela. Ngeshwa, lezi zinqubo zesenzo azikacaci. Ezinye izifundo zesayensi zikhombisile ukuthi esikhundleni soshukela sokwenza amakhalori we-zero-calorie kunganciphisa inani lamagciwane azuzisayo emathuneni futhi aholele ekuphazamisekeni kwamathumbu kwamathumbu, okwandisa ubungozi bokungabekezeleli kukashukela. Ngakolunye uhlangothi, esikhundleni esithile soshukela (ikakhulukazi amakhalori aphansi okwenziwa amakhalori), njenge-isomaliltol ne-lactitol, angadlala indima enhle ngokwandisa inani nokwehlukahlukana kwezinombolo.
Ngaphezu kwalokho, i-Xylitol inomthelela ovimbela inhibitory kuma-enzyme wokugaya afana ne-alpha-glucosidase. I-Nehesperidin inezakhiwo ezithile ze-antioxidant. Ingxube ye-saccharin ne-neohesperidin iyathuthuka futhi yandisa amagciwane azuzisayo. I-Stevioside inomsebenzi wokukhuthaza i-insulin, wehlise ushukela wegazi futhi ulondoloze i-glucose homeostasis. Ngokuvamile, iningi lokudla esikubonayo ngoshukela ongeziwe, ngoba lingavunywa emakethe, asikho isidingo sokukhathazeka kakhulu ngokuphepha kwazo.
Bheka nje uhlu lwezithako lapho uthenga le mikhiqizo bese uwadla ngokulinganisa.
