Funda ukuxhumana phakathi kokudla okuphansi kwe-carb neshukela legazi
Izidlo ezincane -ze-carb ziphathelene nokulinganisa ushukela wegazi (ama-blood glucose). Ngaphandle kokulahlekelwa kwesisindo, sidla ukudla okuphansi kwe-carb ukugcina ushukela wegazi lethu livamile futhi lizinzile. Ukuze uqonde ngokugcwele ukuxhumeka, kuyasiza ukuthi uqale wazi ukuthi umzimba usebenza kanjani ushukela wegazi esimweni esivamile futhi uphinde uhlole ukuthi lokho kuguquka kanjani uma kunenkinga, njengabanesifo sikashukela.
I-Carbohydrates Yenzani Negazi I-Glucose?
Ama-carbohydrate anakho yonke into ngegazi leglucose. Zonke ukudla nge-carbohydrate - kungakhathaliseki ukuthi ilayisi, i-jelly ubhontshisi, noma i-watermelon - yehla ku- ushukela elula emzimbeni wethu uguquke ube yi-glucose ngokusebenzisa izinqubo zamathambo. Le nqubo yiyona eyenza ukuba i-glucose yegazi yethu ikhuphuke. I- carbohydrate ekudleni okunengi okuyi-starchy (amazambane, isinkwa) imane nje iqoqo lamaketanga amade we-glucose, ephuka ngokushesha futhi ephakamisa ushukela wegazi.
Yini Amalungu Ethu Eyenzayo Lapho Igazi Legazi Liphakeme?
Lapho ushukela wegazi wethu ukhuphuka, umzimba wethu uphendula ngokufihla i-insulin ukuyiqinisa. Ishukela liphuma ngaphandle kwegazi bese liguqulwa libe ngamafutha; Umsebenzi oyinhloko we-insulin ukusiza ukugcina ushukela owengeziwe egazini njengamafutha. Abashukela abayisifo sikashukela abakwazi ukulinganisela ushukela wegazi lapho inqubo yokuguqula ukudla ibe namandla. Lapho amazinga okushukela ephakeme, ikhono lamangqamuzana e-pancreas ukwenza i-insulin yehla.
Ama-pancreas agcwalisa kakhulu lokhu kuntuleka kwe-insulini namazinga e-insulini ahlala phezulu, njengokweshukela egazini. Ngokuhamba kwesikhathi, i-pancreas yonakaliswa unomphela kanti neminye imisebenzi yomzimba ithinteka njengemithwalo yegazi enzima, phakathi kwezinye izifo.
Yiziphi izinkinga ngegazi legazi elikhuphukayo?
Kodwa-ke, kubantu abaningi, le nqubo yokusebenzisa umzimba isebenza kahle.
Ngesinye isikhathi, abantu bafinyelela iphuzu empilweni yabo uma kuhamba kancane (noma kungasebenzi kahle kusukela ebuntwaneni). Lokhu kuthiwa yi- insulin ukumelana , futhi enye yemiphumela ukuthi i-insulin eningi kakhulu egazini njengoba umzimba uzama kanzima futhi kunzima ukuletha ushukela phansi. Lapho i-insulin iphezulu, inzuzo yesisindo iningi, ngoba umsebenzi oyinhloko we-insulin uyisitoreji samafutha. Ngakolunye uhlangothi, abantu abanamazinga aphezulu e-insulin kungenzeka banciphise isisindo ezidlweni ezincane-ze-carb.
Ukugcina i-blood glucose evamile kunezinye izinzuzo zezempilo, njengokuvimbela isifo senhliziyo nesifo sikashukela. Ngisho nabangewona abesifo sikashukela bangenengozi yesifo senhliziyo ngezinga eliphezulu legazi le-glucose.
Kuthiwani Nge-Index Ye-Glycemic? Ingabe Akusizi Ukuhlukanisa "I-Carbs" Ehle "Emakhathuni" Okubi?
Impendulo ye-glycemic yomzimba ku-carbohydrate ibalulekile. Nakuba inkomba ye-glycemic inezilinganiso zayo njengethuluzi , inganikeza umqondo onzima wokuthi umzimba wakho ungaphendula kanjani ukudla okunikeziwe. Noma kunjalo, khumbula ukuthi usayizi wokukhonza ubalulekile. Ukudla ukudla okuningi kwe-glycemic carbohydrate ukudla kuzokwandisa i-glucose yegazi lakho. Yingakho abantu abaningi bakuthola kulula nje ukukhawulela ukudla nge-carbohydrate eningi ngokulandela ukudla okuphansi kwe-carb.
