Mhlawumbe, noma yimuphi umuntu obambe iqhaza ekuletheleni umzimba wakhe nempilo yakhe evamile uyazi ukuthi ama-carbohydrate ayizitha zomfanekiso olinganisiwe kahle. Kodwa-ke, lesi sitatimende asikuvumelekile ngaso sonke isikhathi, ngoba ama-carbohydrate ama-carbohydrate ahlukile. Ukuthola izikhwama nge-sweeteners eminyangweni ekhethekile, abantu abaningi bacabanga ukuthi yini ewusizo kakhulu: i-fructose noma ushukela.
I-Fructose ne-glucose ushukela
Ukungena emzimbeni, ushukela uhlukaniswa waba izinhlobo ezimbili zama-carbohydrate alula: i-fructose ne-glucose, bese kuthi ngamunye wabo uqhubeke. I-glucose isetshenziselwa amandla, ingxenye yayo igcinwe esibindi ngesimo se-glycogen, futhi kuphela izinsalela ezigcinwe ekugcinweni njengamafutha ediphithi. Le-carbohydrate ivuselela nokukhiqizwa kwe-insulini, i-hormone yama-anabolic, eyenza ukunciphisa izinqubo zokugaya nokukhulisa amandla. Ngenxa yalokho, ukuzwa kwe-saturation kubonakala. Kodwa esikhathini esizayo kukhona ukwehla okunjalo okubukhali ekuhlungeni kwe-hormone, futhi lena akuyona indlela engcono kakhulu yokuthinta inhlalakahle.
I-Fructose ine-caloric efanayo ne-caloric njengokweshukela, kodwa ngokungafani nalokhu okulandelayo, akukho ezinye i-carbohydrates esikhwameni eziqukethe. Emzimbeni, i-fructose igajwe ngokungafani ne-glucose. Kubonakala ukuthi le carbohydrate ngokuyinhloko igcinwa ngendlela yamafutha, futhi kuphela lapho isetshenziselwa ukuthola amandla. Ngakho-ke, singasho ngokuphepha ukuthi ukusetshenziswa kwalo kuholela ekwandeni kwamanzimba omzimba, ukuze i-fructose esikhundleni soshukela lapho ukulahlekelwa isisindo akuyona indlela engcono kakhulu.
I-insulini ne-fructose
Into ewukuthi i-fructose inamandla kakhulu ivuselela ukufihla kwe-insulini, ngokungafani ne-glucose. Ngakho-ke, ukusetshenziswa kwalesi carbohydrate ngokulahlekelwa isisindo kuholela emiphumeleni engathandeki:
- ukuqoqwa kwamafutha;
- ukunciphisa ukusetshenziswa kwamandla;
- ukubonakala kwendlala.
Ukususwa kweshukela nge-fructose kuyafaneleka kubantu abane-type 2 yesifo sikashukela esinezinkinga nge-pancreas, kubabo abaveza i-fructose ngendlela ehlanzekile.
I-Sugar ngumthombo wama-khalori engenamsebenzi
Uma kukhona ukukhetha "fructose noma ushukela," kungcono ukunikeza okuthandayo ushukela kunokusebenzisa kuphela fructose. Kodwa, ngokuqondile, ushukela ungumthombo wama-calorie engenamsebenzi, ngoba awunamavithamini, izakhi zokulandelela nezinye izakhi. Ngakho-ke, ukuthola ama-carbohydrate alula kakhulu kunezithelo .
