Izinkinga ngokuyinhloko zihlobene nokuqukethwe kwama-carbohydrate. Amazambane ayimifino enomsoco evame ukuthola indlela yayo kumapuleti esidlo sakusihlwa. Naphezu kokuguquguquka kanye nokudla okunempilo kwemifino yezimpande, ukuyidla kungadala izingozi ezifihlekile zezempilo.
Izinkinga ngokuyinhloko zihlobene ne-carbohydrate equkethwe yimifino, aqukethe ama-carbohydrates amaningi agayeka umzimba ngokushesha, abangele i-spike bese ukwehla kushukela wegazi kanye namazinga e-insulin. "
I-GI iwuhlelo lokulinganisa ukudla okunama-carbohydrates - ikhombisa ukuthi ukudla ngakunye kuwuthinta ngokushesha kangakanani ushukela wakho wegazi (iglucose) uma udliwa uwedwa. Lapho ukudla kwehla ngokushesha kushukela wegazi, kuba mkhulu umphumela wawo emazingeni kashukela egazini - okungase kwandise ingozi yokuba nesifo sikashukela sohlobo 2.
Ngaphezu kwalokho, “umphumela ofana ne-roller coaster womthwalo ophezulu we-glycemic wokudla ungabangela abantu ukuba baphinde bazizwe belambile ngemva nje kokudla, okungase kubangele ukudla ngokweqile,” kuxwayisa i-Harvard Health. “Ngokuhamba kwesikhathi, ukudla okunamazambane amaningi nokudla okufanayo okugaya ngokushesha okunama-carbohydrate amaningi kungaba nomthelela ekukhuluphaleni, isifo sikashukela nesifo senhliziyo.”
Ucwaningo lubonisa ukuthi ukukhuluphala kuyinkinga ethile. Ucwaningo olwanyatheliswa kuyi-New England Journal of Medicine lulandele ukudla kanye nezindlela zokuphila zamadoda nabesifazane abangu-120,000 iminyaka engu-20.
Abacwaningi babekhathazeke ngokuyinhloko ngokuthi izinguquko ezincane ekukhethweni kokudla zibe nomthelela kanjani ekuzuzeni isisindo ngokuhamba kwesikhathi. Bathole ukuthi abantu abenyusa ukudla kwabo amazambane athosiwe namazambane abhakiwe noma acushiwe bathola isisindo esengeziwe ngokuhamba kwesikhathi-okungeziwe okungu-1.5 no-0.5 kg njalo eminyakeni emine, ngokulandelana.
Ngaphezu kwalokho, abantu abanciphisa ukudla kwabo lokhu kudla bathola isisindo esincane, njengoba kwenza abantu abenyusa izinga lokudla kweminye imifino. Ingozi yokuthi amazambane angabangela ukuthuthukiswa kwesifo senhliziyo ingase ihlotshaniswe nomfutho wegazi ophezulu, isandulela sezinkinga zenhliziyo.
Abacwaningi baseHarvard Medical School bafunde amadoda nabesifazane abangaphezu kuka-187,000 ezifundweni ezintathu ezinkulu zaseMelika. Baqhathanisa abantu ababedla amazambane abhakiwe, acushiwe, noma abilisiwe, ama-chips, noma amazambane abilisiwe ngenyanga kanye nabantu abadla ukudla okune noma ngaphezulu ngesonto.
Bathole ukuthi ingozi yomfutho wegazi ophakeme ibiphezulu ngo-11% uma ababambiqhaza bedla ukudla okune noma ngaphezulu kwamazambane abhakiwe, acushiwe, noma abilisiwe ngeviki, kanye nengozi ephakeme engu-17% yama-French fries (chips) uma kuqhathaniswa nabantu ababenamazambane angaphansi kweyodwa. ukukhonza ngenyanga.
Abacwaningi abatholanga ingozi eyengeziwe ngokusetshenziswa okuphezulu kwe-chip. Kodwa-ke, amanye ama-chips ocwaningweni ayemancane kakhulu ngesisindo kunezinye izinhlobo zamazambane (ama-28 g ama-chips uma kuqhathaniswa ne-113 g yamafrimu), ngakho-ke kungenzeka ukuthi inani elincane lamazambane kungenzeka libe nomthelela emiphumeleni.
Ukuqinisekisa lokhu kuhlangana, ucwaningo lwathola ukuthi ukufaka esikhundleni samazambane ngokuphakelwa kwemifino kunganciphisa ingozi yomfutho wegazi ophakeme.
Nokho, ucwaningo lunokulinganiselwa okuthile. “Lolu hlobo lokufunda lungakhombisa kuphela ukuhlangana, hhayi ubudlelwano bembangela. Ngakho-ke, asikwazi ukuphetha ngokuthi amazambane abangela umfutho wegazi ophezulu, futhi asikwazi ukuchaza imbangela yemiphumela ebonwe ocwaningweni, "kusho uVictoria Taylor, isazi sezokudla esiphezulu eBritish Heart Foundation.
"Kubalulekile futhi ukuqaphela ukuthi lolu wucwaningo olwenziwe e-US, lapho imihlahlandlela yezokudla nezincomo zihlukile kwezase-UK."
