Isizathu esiphambili sokutyeba kukutya ngokugqithisileyo kokutya kunye nesalathisi esiphezulu se-glycemic index.
Iqela lamazwe ngamazwe lezazinzulu ezisuka eUnited States, eDenmark naseKhanada lifumene oonobangela abatsha bokutyeba ngokugqithiseleyo. Abaphandi bathi azihlobene nesixa sokutya okusetyenzisiweyo. Inqaku elipheleleyo kukubunjwa kwayo. Oku kuchazwe kwinqaku elipapashwe kwi-American Journal of Clinical Nutrition, u-EurekAlert ubhala.
Ngokutsho kwamaZiko e-US oLawulo lweSifo kunye noThintelo (CDC), ngaphezu kwe-40% yabantu abadala base-US batyebile. Aba bantu basemngciphekweni omkhulu wokuba nesifo sentliziyo, istroke, uhlobo lwesi-2 seswekile, kunye neentlobo ezithile zomhlaza.
Ngokwesiko, indlela yokunciphisa umzimba icebisa ukunciphisa inani leekhalori ozithathayo kunye nokwandisa inkcitho yakho ngokwenza umsebenzi womzimba. Ngale ndlela unokulinganisa amandla akho.
Nangona kunjalo, ababhali beli phepha bacebise enye imodeli ye-carbohydrate-insulin. Ithi eyona nto iphambili yokutyeba kukutya okuninzi okune-glycemic index ephezulu, ngakumbi ukutya okucutshungulwayo kunye nenani elikhulu le-carbohydrates yokugaya ngokukhawuleza.
Ukutya okunjalo kwenza isiseko sendlela yanamhlanje yaseNtshona yokutya kwaye kubangele utshintsho lwe-hormonal olunciphisa inkqubo ephambili ejongene nokukhuluphala - imetabolism.
“Xa sisitya iicarbohydrates ezicutshungulwayo, umzimba wonyusa ukukhutshwa kwe-insulin kwaye ucinezela ukukhutshwa kweglucagon. Oku ke, kuxela iiseli ezinamafutha ukuba zigcine iikhalori ezininzi, zishiya amandla amancinci okufaka izihlunu kunye nezinye izihlunu ezisebenzayo, utshilo ukukhululwa.
Ingqondo, ihlalutya olu lwazi, ithatha isigqibo sokuba umzimba awufumani amandla aneleyo kwaye ukwandisa ukuvakalelwa kwendlala.
“Ukunciphisa ukuthathwa kweecarbohydrates ezetyiswa ngokukhawuleza akuphelisi nje oyena nobangela uphambili wokufumba kwamafutha emzimbeni kodwa kwakhona kuthomalalisa imvakalelo eqhubekayo yokulamba,” zaqukumbela ngelithi iingcali.
