Ingabe bonke utshwala obushukela bukunikeza isifo sohudo?
Ingabe zonke izinhlobo zezinto ezifakwa esikhundleni sikashukela ekudleni zinempilo?
Namuhla sizokhuluma ngakho. Yini ngempela utshwala obushukela? Ama-alcohol kashukela ama-polyols ngokuvamile enziwa kusuka kushukela omningi ohambisanayo. Isibonelo, ukuncishiswa kwe-xylose yi-xylitol ejwayelekile.
Ngaphezu kwalokho, ama-alcohol ashukela okwamanje asathuthukiswa ami kanje:
IGlucose → sorbitol fructose → mannitol lactose → Lactitol glucose → erythritol sucrose → isomaltol
I-Sorbitol Sugar alcohol manje isingesinye "sezithasiselo zokudla ezisebenzayo". Kungani ifakwa ekudleni? Ngoba inezinzuzo eziningi.
Okokuqala, ukuzinza kotshwala obushukela ekushiseni kwe-asidi kuhle, futhi ukusabela kwe-Maillard akulula kangako ukwenzeka ekushiseni, ngakho ngokuvamile akubangeli ukulahlekelwa kwezakhi kanye nesizukulwane kanye nokuqoqwa kwama-carcinogens. Okwesibili, ama-alcohol ashukela awasetshenziswa ama-microorganisms emlonyeni wethu, okunciphisa inani le-pH emlonyeni, ngakho-ke akugqwali amazinyo;
Ngaphezu kwalokho, utshwala obushukela ngeke bukhuphule inani likashukela wegazi lomzimba womuntu, kodwa futhi bunikeze inani elithile lamakholori, ngakho-ke lungasetshenziswa njengesiphuzo esinomsoco kubantu abanesifo sikashukela.
Kunezinhlobo eziningi zokudla okulula kwe-xylitol nama-dessert emakethe. Ngakho-ke uyabona ukuthi kungani utshwala obushukela buyinto yakudala "isithasiselo sokudla esisebenzayo"? Phela, inobumnandi obuphansi, ukuphepha okuphezulu okunomsoco, ayibangeli ukubola kwamazinyo, ayiphazamisi inani likashukela egazini, nokuzinza kokushisa kwe-asidi ephezulu.
Yebo, utshwala obushukela bulungile, kodwa ungabi nomhobholo - otshwala abaningi bakashukela ngokuvamile bayalaxaza uma buphuzwa ngemithamo emikhulu.
I-Maltitol idla isifo sohudo kakhulu, yisiphi isimiso?
Ngaphambi kokuchaza isimiso, ake siqale sibheke imiphumela yokuhlanzwa kwezidakamizwa eziningana ezivamile (ezivame ukusetshenziswa) ushukela.
| Utshwala obushukela | Ubumnandi(i-sucrose =100) | Umphumela wohudo |
| I-Xylitol | 90-100 | ++ |
| I-Sorbitol | 50-60 | ++ |
| I-Mannitol | 50-60 | +++ |
| I-Maltitol | 80-90 | ++ |
| I-Lactitol | 30-40 | + |

Uma udla ama-alcohol ashukela, awaphulwa yi-pepsin, kodwa aya ngqo emathunjini. Utshwala obuningi obushukela bumuncwa kancane kakhulu emathunjini, okudala umfutho we-osmotic ophezulu, obangela ukuphakama kwengcindezi ye-osmotic yokuqukethwe kwamathumbu, bese amanzi e-mucosal odongeni lwamathumbu engena emgodini wamathumbu, bese ungena. isiphithiphithi.
Ngesikhathi esifanayo, ngemva kokuba utshwala obushukela bungena emathunjini amakhulu, buzovutshelwa amagciwane amathumbu ukuze akhiqize igesi, ngakho isisu sizophinde sibe flatulence. Nokho, akubona bonke utshwala obunoshukela obukhiqiza isifo sohudo negesi.
Ngokwesibonelo, i-erythritol, okuwukuphela kwe-alcohol kashukela ene-calorie eyi-zero, inesisindo esincane samangqamuzana futhi kulula ukumunca, futhi ingcosana kuphela yayo ingena emathunjini amakhulu ukuze ivutshelwe amagciwane. Umzimba womuntu futhi ukubekezelela okuphezulu kwe-erythritol, i-80% ye-erythritol egazini lomuntu, ayikhiqizi ama-enzyme, ayinikezi amandla emzimbeni, ayihlanganyeli kumetabolism kashukela, ingakhishwa ngomchamo kuphela, ngokuvamile akubangeli isifo sohudo kanye nokucaba.
Umzimba womuntu unokubekezelela okuphezulu kwe-isomaltol, futhi ukudla kwansuku zonke kwe-50g ngeke kubangele ukuphazamiseka kwamathumbu. Ngaphezu kwalokho, i-isomaltol nayo iyisici esihle kakhulu sokwanda kwe-bifidobacterium, engakhuthaza ukukhula nokukhiqizwa kabusha kwe-bifidobacterium, igcine ibhalansi ye-microecological yepheshana lamathumbu, futhi ihambisana nempilo.
Ukufingqa, izimbangela eziyinhloko zohudo kanye ne-flatulence okubangelwa utshwala obushukela yilezi: okokuqala, awunqunywanga ngama-enzyme omuntu kodwa usetshenziswa izitshalo zamathumbu; Okunye ukukubekezelela okuphansi komzimba kuwo.
Uma ukhetha i-erythritol ne-isomaltol ekudleni, noma uthuthukise ifomula ukwandisa ukubekezelelana komzimba notshwala obushukela, unganciphisa kakhulu imiphumela emibi yotshwala obushukela.
Yini enye esikhundleni sikashukela? Ingabe iphephile ngempela?
Abantu abaningi bayathanda ukudla okumnandi, kodwa ubumnandi busilethela injabulo kanye kanye, buphinde bulethe ukukhuluphala, ukubola kwamazinyo nesifo senhliziyo. Ngakho-ke ukuze kuhlangatshezwane nezidingo ezimbili zokunambitha nempilo, kwazalwa okubambele ushukela.
Izithako zikashukela ziyiqembu lezinhlanganisela ezenza ukudla kube mnandi futhi kube nama-kilojoule aphansi. Ngaphandle kotshwala obushukela, kunezinye izinhlobo ze-sugar substitutes, ezifana ne-licorice, i-stevia, i-monkfruit glycoside, i-soma sweet nezinye i-substitutes ushukela wemvelo; Futhi i-saccharin, i-acesulfameae, i-aspartame, i-sucralose, i-cyclamate nezinye izithameli zikashukela zokwenziwa. Iziphuzo eziningi emakethe zibhalwe ukuthi "akukho shukela, ushukela ongu-zero", eziningi empeleni zisho ukuthi "akukho sucrose, akukho fructose", futhi ngokuvamile zengeza ama-sweeteners (okuthatha indawo kashukela) ukuqinisekisa ubumnandi. Isibonelo, uhlobo olulodwa lwesoda luqukethe i-erythritol ne-sucralose.
Esikhathini esedlule, umqondo wokuthi "akukho ushukela"futhi"ushukela onguziro" kubangele izingxoxo ezisabalele ku-inthanethi, futhi abantu abaningi bangabaza ukuphepha kwayo.
Ukuyibeka kanjani? Ubudlelwano phakathi kwezinto ezithatha indawo kashukela nempilo bunzima. Okokuqala, esikhundleni sikashukela wemvelo sinomthelela omuhle empilweni yomuntu. Njengamanje, ubunzima obuyinhloko buyizindleko zabo zokukhiqiza kanye nokutholakala kwemithombo yemvelo.
I-Momordica iqukethe ushukela wemvelo "i-Momordica glucoside". Ucwaningo luye lwabonisa ukuthi i-momoside ingathuthukisa ukusetshenziswa kwe-glucose namafutha, ikhulise ukuzwela kwe-insulin, okulindeleke ukuthi ithuthukise isifo sikashukela. Ngeshwa, lezi zindlela zokusebenza azikacaci. Olunye ucwaningo lwesayensi lubonise ukuthi i-zero-calorie synthetic sugar substitutes inganciphisa inani lamagciwane anenzuzo emathunjini futhi iholele ekuphazamisekeni kwezitshalo zamathumbu, okwandisa ingozi yokungabekezelelani kwe-glucose. Ngakolunye uhlangothi, ezinye izithasiselo zikashukela (ikakhulukazi izakhi zokwenziwa ezinekhalori ephansi), njenge-isomaltol ne-lactitol, zingadlala indima enhle ngokwandisa inani nokuhlukahluka kwezitshalo zamathumbu.
Ngaphezu kwalokho, i-xylitol inomphumela ovimbelayo kuma-enzyme wokugaya njenge-alpha-glucosidase. I-Neohesperidin inezici ezithile ze-antioxidant. Ingxube ye-saccharin ne-neohesperidin ithuthukisa futhi ikhulise amabhaktheriya anenzuzo. I-Stevioside inomsebenzi wokukhuthaza i-insulin, yehlisa ushukela wegazi kanye nokugcina i-glucose homeostasis. Ngokuvamile, ukudla okuningi esikubona ngoshukela owengeziwe, njengoba kungavunyelwa emakethe, asikho isidingo sokukhathazeka kakhulu ngokuphepha kwabo.
Bheka nje uhlu lwezithako uma uthenga le mikhiqizo futhi uyidle ngokusesilinganisweni.
