Ngaba zonke ii-alcohols ezineswekile ziyakubangela ukuba urhudo?
Ngaba zonke iintlobo zezinto ezithatha indawo yeswekile ezongezwa ekutyeni zisempilweni?
Namhlanje siza kuthetha ngayo. Yintoni kanye kanye iswekile alcohol? Iiswekile alcohols ziipolyols ezenziwe ngeentlobo ezahlukeneyo zeswekile ezifanayo. Umzekelo, ukunciphisa i-xylose yi-xylitol eqhelekileyo.
Ukongeza, ii-alcohols zeswekile ezisaphuhliswayo ngoku zezi zilandelayo:
Iswekile → i-sorbitol fructose → i-mannitol lactose → i-Lactitol glucose → i-erythritol sucrose → isomaltol
ISorbitol Iswekile yotywala ngoku yenye yezona "zongezo zokutya ezisebenzayo" ziqhelekileyo. Kutheni ifakwa ekutyeni? Kuba ineenzuzo ezininzi.
Okokuqala, ukuzinza kwee-sugar alcohols kubushushu be-asidi kulungile, kwaye i-Maillard reaction ayilula kangako ukwenzeka kubushushu, ngoko ke ngokubanzi ayibangeli ukulahleka kwezondlo kunye nokuveliswa kunye nokuqokelelwa kwee-carcinogens. Okwesibini, ii-sugar alcohols azisetyenziswa ziintsholongwane ezikwimilomo yethu, nto leyo enciphisa ixabiso le-pH emlonyeni, ukuze ingadli amazinyo;
Ukongeza, ii-alcohols zeswekile aziyi kunyusa ixabiso leswekile egazini lomzimba womntu, kodwa zikwabonelela ngomlinganiselo othile weekhalori, ngoko ke zingasetyenziswa njenge-sweetener yesondlo kubantu abanesifo seswekile.
Kukho iintlobo ezininzi ze-xylitol snacks kunye needizethi ezithengiswayo. Ngoko ke ungabona ukuba kutheni i-sugar alcohols iyinto eqhelekileyo "isongezo sokutya esisebenzayo"Emva kwayo yonke loo nto, ayinancasa ingako, ayinazo izondlo ezininzi, ayibangeli ukubola kwamazinyo, ayichaphazeli ixabiso leswekile egazini, kwaye ayizinzisi ubushushu obuphezulu."
Kakade ke, ii-sugar alcohols zilungile, kodwa ungabi namdla - uninzi lwee-sugar alcohols zihlala zikhupha isisu xa zithathwa kakhulu.
I-Maltitol itya urhudo oluninzi, nguwuphi umgaqo?
Ngaphambi kokuba sichaze lo mgaqo, masiqale sijonge iziphumo zokucoca ezibangelwa zii-alcohols ezininzi zeswekile eziqhelekileyo (ezisetyenziswa rhoqo).
| Utywala obuneswekile | Ubumnandi(i-sucrose = 100) | Isiphumo sorhudo |
| I-Xylitol | 90-100 | ++ |
| ISorbitol | 50-60 | ++ |
| IMannitol | 50-60 | +++ |
| I-Maltitol | 80-90 | ++ |
| I-Lactitol | 30-40 | + |

Xa usitya i-sugar alcohols, aziqhekeki yi-pepsin, kodwa ziya ngqo emathunjini. Uninzi lwe-sugar alcohols lufunxwa kancinci emathunjini, nto leyo edala uxinzelelo oluphezulu lwe-osmotic, nto leyo ebangela ukuba uxinzelelo lwe-osmotic lomxholo wamathumbu lunyuke, aze amanzi e-mucosal eludongeni lwamathumbu angene kwi-intestinal cavity, uze emva koko ube sengxakini.
Kwangaxeshanye, emva kokuba iswekile yotywala ingene emathunjini amakhulu, iya kubila yintsholongwane yamathumbu ukuze ivelise igesi, ngoko ke nesisu siya kuqunjelwa. Nangona kunjalo, ayizizo zonke iswekile yotywala ezibangela urhudo kunye negesi.
Umzekelo, i-erythritol, iswekile ekuphela kwayo engenazo iikhalori, inobunzima obuncinci beemolekyuli kwaye kulula ukuyifunxa, kwaye incinci kuphela yayo engena emathunjini amakhulu ukuze ivundiswe ziintsholongwane. Umzimba womntu ukwanokunyamezela okuphezulu kwe-erythritol, i-80% ye-erythritol egazini lomntu, ayilungiswanga zii-enzymes, ayiniki amandla emzimbeni, ayithathi nxaxheba kwimetabolism yeswekile, inokukhutshwa kuphela ngomchamo, ngoko ke ayibangeli urhudo kunye nokuthamba.
Umzimba womntu unyamezela kakhulu i-isomaltol, kwaye ukutya i-50g imihla ngemihla akuyi kubangela ukungakhululeki kwesisu. Ukongeza, i-isomaltol ikwayinto entle kakhulu yokwanda kwe-bifidobacterium, enokukhuthaza ukukhula nokuzala kwe-bifidobacterium, igcine ibhalansi ye-microecological yendlela yamathumbu, kwaye inceda kwimpilo.
Ngamafutshane, izizathu eziphambili zorhudo kunye nokuqunjelwa okubangelwa yiswekile yotywala zezi: okokuqala, ayigaywa zii-enzymes zabantu kodwa isetyenziswa ziintyatyambo zamathumbu; Esinye kukunganyamezelani komzimba nayo.
Ukuba ukhetha i-erythritol kunye ne-isomaltol ekutyeni, okanye uphucule ifomula ukuze wonyuse ukunyamezela komzimba iswekile alcohol, unganciphisa kakhulu iziphumo ebezingalindelekanga zeswekile alcohol.
Yintoni enye into ethatha indawo yeswekile? Ingaba ikhuselekile ngokwenene?
Abantu abaninzi bayakuthanda ukutya iilekese, kodwa iilekese zisizisa ulonwabo ngaxeshanye, zikwazisa ukutyeba kakhulu, ukubola kwamazinyo kunye nesifo sentliziyo. Ngoko ke ukuze kuhlangatyezwane neemfuno ezimbini zencasa nempilo, kwazalwa indawo yeswekile.
Izithako zeswekile liqela leekhompawundi ezenza ukutya kube mnandi kwaye kube neekhalori eziphantsi. Ukongeza kwi-sugar alcohols, kukho ezinye iintlobo zezithako zeswekile, ezifana ne-licorice, i-stevia, i-monkfruit glycoside, i-soma sweet kunye nezinye izinto ezithako zeswekile yendalo; Kunye ne-saccharin, i-acesulfameae, i-aspartame, i-sucralose, i-cyclamate kunye nezinye izinto ezithako zeswekile ezenziweyo. Iziselo ezininzi ezithengiswayo zibhalwe ngokuthi "akukho swekile, akukho swekile", ezininzi zithetha "akukho sucrose, akukho fructose", kwaye zihlala zongeza izithako zeswekile (izithako zeswekile) ukuqinisekisa ubumnandi. Umzekelo, uhlobo olunye lwesoda luqulethe i-erythritol kunye ne-sucralose.
Kwixesha elithile elidlulileyo, ingcamango "akukho swekile"kwaye"akukho swekile"Kubangele ingxoxo ebanzi kwi-intanethi, kwaye abantu abaninzi babuza ukhuseleko lwayo."
Ungayibeka njani le nto? Ubudlelwane phakathi kwezinto ezithatha indawo yeswekile nempilo buyinkimbinkimbi. Okokuqala, izinto ezithatha indawo yeswekile yendalo zinempembelelo entle kwimpilo yabantu. Okwangoku, ubunzima obukhulu bukwiindleko zazo zemveliso kunye nokufumaneka kwezixhobo zendalo.
IMomordica ineswekile yendalo "iMomordica glucoside". Izifundo zibonise ukuba i-momoside inokuphucula ukusetyenziswa kweswekile kunye namafutha, yonyuse uvakalelo lwe-insulin, okulindeleke ukuba iphucule isifo seswekile. Ngelishwa, ezi ndlela zokusebenza azikacaci. Ezinye izifundo zesayensi zibonise ukuba izinto ezithatha indawo yeswekile eyenziweyo ezingenazo iikhalori zinokunciphisa inani leebhaktheriya eziluncedo emathunjini kwaye zikhokelele kwiingxaki zezityalo zamathumbu, zinyuse umngcipheko wokunganyamezelani neswekile. Kwelinye icala, ezinye izinto ezithatha indawo yeswekile (ikakhulu ezo zithatha indawo yeswekile eneekhalori eziphantsi), ezifana ne-isomaltol kunye ne-lactitol, zinokudlala indima entle ngokwandisa inani kunye nokwahlukahluka kwezityalo zamathumbu.
Ukongeza, i-xylitol inefuthe lokuthintela ii-enzymes zokugaya ukutya ezifana ne-alpha-glucosidase. I-Neohesperidin ineempawu ezithile ze-antioxidant. Umxube we-saccharin kunye ne-neohesperidin uphucula kwaye wonyusa iintsholongwane eziluncedo. I-Stevioside inomsebenzi wokukhuthaza i-insulin, ukwehlisa iswekile yegazi kunye nokugcina i-glucose homeostasis. Ngokubanzi, uninzi lokutya esikubonayo kunye neswekile eyongeziweyo, ekubeni zinokuvunywa ukuba zithengiswe, akukho mfuneko yokukhathazeka kakhulu malunga nokhuseleko lwazo.
Jonga nje uluhlu lwezithako xa uthenga ezi mveliso uze uzitye ngokulinganisela.
