Uma kukhulunywa ngokwehlisa isisindo, umbuzo omdala uwukuthi ngabe kubalulekile yini ukuthi wehlisa isisindo sakho. Ukuhlolwa kwamuva nje kwezokwelapha kunikeze impendulo eshukumisa ingqondo: kubalulekile. Abacwaningi eWashington University eSt. Louis baqhathanise ukudla okuthathu okudumile kubantu abanokukhuluphala ngokweqile, isifo sikashukela esingakafiki, kanye nesifo sesibindi esinamafutha, futhi bathola ukuthi nakuba bonke abathathu bathola ukwehla kwesisindo okufanayo, imiphumela ye-metabolic yayingafani.
Lolu cwaningo, olwanyatheliswa kuyi- Cell Metabolism , lulandele abahlanganyeli abangu-42 izinyanga ezine kuya kwezinhlanu. Bonke bathola ukudla okulungiselelwe yithimba locwaningo futhi kwaqashwa masonto onke nguchwepheshe wezokudla. Umgomo kwakuwukuba umhlanganyeli ngamunye anciphise cishe u-10% wesisindo somzimba wabo, okwafezwa kuwo wonke amaqembu amathathu. Kodwa lapho kuhlaziywa okwakwenzeka emizimbeni yabo, kwavela umehluko ngokushesha.
Lena yindlela ucwaningo olwenziwe ngayo
Abahlanganyeli babelwa ngokungahleliwe kokunye kokudla okuthathu: ukudla okune-carbohydrate ephansi kakhulu , ukudla kwaseMedithera, noma ukudla okunamafutha amancane, okunemifino eminingi. Ukwakheka kwezakhamzimba eziningi kwahlukahluka kakhulu. Ekudleni kwe-ketogenic, ama-calories angu-4% kuphela avela kuma-carbohydrate kanye nama-73% avela emafutheni. Ekudleni kwaseMedithera, ama-carbohydrate abalelwa ku-50% kanti amafutha abalelwa ku-35%. Futhi ekudleni okunamafutha amancane, ama-carbohydrate abalelwa ku-70% kanti amafutha aba ngu-15%.
Abacwaningi balungisa ukudla kwama-calories omuntu ngamunye ukuze ukwehla kwesisindo kulingane. Lokhu kwabavumela ukuthi bahlukanise umphumela wokwakheka kokudla, ngale kokunciphisa isisindo okulula. Wonke amaqembu athuthukise ukuzwela kwawo kwe-insulin futhi anciphisa ubukhulu bamafutha awo, kodwa lapho ebheka isibindi, indaba yashintsha.
Imiphumela: Amafutha esibindi kanye ne-prediabetes
Umehluko ovelele kakhulu utholakale enanini lamafutha aqongelelwe esibindini. Abahlanganyeli abalandela ukudla kwe-ketogenic banciphise amafutha esibindini sabo ngesilinganiso esingu-67%, kanti emaqenjini okudla aseMedithera nakwamafutha aphansi ukwehla kwaba cishe ngu-45%. Ngaphezu kwalokho, ukuzwela kwesibindi ku-insulin kuthuthuke kabili noma kathathu eqenjini le-ketogenic, okugqamisa indima yesibindi ekucutshungulweni kwamafutha.
Okunye okuphawulekayo okwatholakala kwakuwukusabalala kwesifo sikashukela sangaphambi kokwelashwa. Ngemva kokungenelela, cishe ingxenye yabahlanganyeli eqenjini le-keto ayisahlangabezani nezindinganiso zesifo sikashukela sangaphambi kokwelashwa. Eqenjini laseMedithera, isilinganiso sasingu-29%, kanti eqenjini lokudla okusekelwe ezitshalweni okunamafutha aphansi, u-7% kuphela. Ukunciphisa ukudla ama-carbohydrate kubonakala kunomphumela oqondile wokwelapha ekugayweni kwe-metabolism , ngale nje kokulahlekelwa isisindo.
Kuthiwani nge-cholesterol nama-hormone?
Enye yezinto ezivame ukwesaba ukudla okunamafutha amaningi ukuthi kuphakamisa amazinga e-cholesterol. Kodwa-ke, lokhu bekungenjalo kulolu cwaningo. Ababhali bagcizelele ukuthi abahlanganyeli eqenjini le-ketogenic abazange babhekane nokwanda kwamafutha egazini noma i-cholesterol , naphezu kokudla ingxenye enkulu yamafutha. Lokhu kuphambene nezinkolelo ezithile ezidumile futhi kunikeza ulwazi oluqinisekisayo kulabo abacabangela lolu hlobo lokudla.
Kuye kwabonakala nezinguquko ezinkulu zamahomoni. Iqembu le-keto libonise ukwanda okukhulu kwe-glucagon, i-hormone ekhuthaza ukuthuthwa kwamafutha agciniwe, kanye nokwehla okukhulu kwe-insulin egazini. Lezi zinguquko zingachaza ukuthi kungani amafutha esibindi ehle kakhulu kuleli qembu.
Imikhawulo kanye nomongo
Ababhali ngokwabo bayavuma ukuthi lolu cwaningo lunemikhawulo. Usayizi wesampula mncane, isikhathi sokulandelela sifushane, futhi ababambiqhaza bathole konke ukudla kwabo okulungiselelwe kusengaphambili, okungabonisi izimo zangempela. Ngaphezu kwalokho, imiphumela ibhekisela kuphela kubantu abanokukhuluphala ngokweqile, isifo sikashukela esingakafiki, kanye nesifo sesibindi , ngakho-ke ayinakuhunyushwa kubantu abavamile.
Okwamanje, ukudla kwaseMedithera kuyaqhubeka nokuba nobufakazi obuqinile obusekela izinzuzo zako zesikhathi eside zempilo yenhliziyo nemithambo yegazi. Ukukhetha phakathi kokudla okukodwa noma okunye kufanele kusekelwe ezidingweni zomuntu ngamunye kanye nephrofayili yakhe , futhi njalo ngeseluleko sochwepheshe bezempilo. Lolu cwaningo alusho ukuthi luphumelele, kodwa kunalokho lugcizelela ukuthi ukwakheka kokudla kubaluleke kakhulu kunalokho obekucatshangwa ngaphambilini.
Ngamafuphi, lolu cwaningo luphakamisa iphuzu elithakazelisayo: abantu ababili bangalahlekelwa isisindo esifanayo kodwa bangabi nezinguquko ezifanayo ze-metabolic. Ukwehla kwesisindo kusabalulekile, kodwa indlela esetshenziswayo inganikeza izinzuzo ezengeziwe, ikakhulukazi uma kunezinkinga zesibindi nezinkinga zokulawula ushukela. Abacwaningi sebevele basebenza ekuhlanganiseni lokhu kudla nama-inhibitor e-GLP-1 ukuze baqonde ukuthi bangahambisana kanjani. Okwamanje, isincomo esinengqondo kakhulu ukungabheki ukudla okulingana nosayizi owodwa, kodwa kunalokho okuhambisana kahle nesimo ngasinye, ngokuqondiswa uchwepheshe.
