Wake wacabanga ukuthi ukudla ngezikhathi ezingavamile ngempelasonto kungaba namuphi umphumela emzimbeni wethu? Le mfihlakalo idalulwe wucwaningo olusha oluvela eNyuvesi yaseBarcelona, eluphethe ngokuthi ukungahambi kahle kwezinhlelo ngezimpelasonto (ukudla i-jet lag) kungase kuhlobane nokwanda kwenani lomzimba.
Idatha, eshicilelwe ku Umagazini we- Nutrients, zitholwe ngaphandle kwezici ezifana nekhwalithi yokudla, izinga lomsebenzi womzimba, ukunensa kwendiza yomphakathi (umehluko ezikhathini zokulala ngempelasonto) noma i-chronotype (isimo semvelo sesikhathi esithile sokulala nokuphaphama). Nakuba i-BMI ingewona umaka othembekile wokwazi ukuthi umuntu unempilo yini noma cha, kubonisiwe ukuthi umthelela omkhulu uyenzeka uma kukhona umehluko wesikhathi wamahora angu-3 noma ngaphezulu phakathi kokudla ngezimpelasonto nezinye izinsuku.
Kungani kubalulekile ukuba njalo ngezikhathi zokudla?
Ngokusho kwabacwaningi, lolu ucwaningo lokuqala olubonisa ukubaluleka kwezikhathi zokudla ezivamile (nangezimpelasonto) zokulawula isisindo. Baqinisekisa ukuthi kungaba yinto okufanele icatshangelwe njengengxenye yezinkombandlela zokudla okunomsoco ukuze kuvinjelwe ukukhuluphala.
Eminyakeni yamuva, kuye kwaboniswa ukuthi umzimba uthatha ama-calories ngokuhlukile kuye ngesikhathi sosuku. Isibonelo, ukudla kwasemini noma isidlo sakusihlwa kuye kwaxhunyaniswa nengozi eyengeziwe yokukhuluphala. Ngokusho kwababhali, “Lo mehluko uhlobene newashi lethu lebhayoloji, elihlela imizimba yethu okwesikhashana ukuze ihlanganise futhi igaye amakholori esiwadla phakathi nosuku.«. Ebusuku, ngakolunye uhlangothi,ilungiselela umzimba ukuzila okwenzeka lapho silele".
«Ngakho-ke, lapho ukungeniswa kwenzeka njalo, el iwashi elijikelezayo iqinisekisa ukuthi imigudu ye-metabolic yomzimba iyasebenza ukuze ihlanganise imisoco. Kodwa-ke, lapho ukudla kudliwe ngesikhathi esingajwayelekile, izakhi zingasebenza emshinini wamangqamuzana wamawashi angaphandle (ngaphandle kobuchopho), ziguqule isimiso sazo futhi, ngenxa yalokho, ziguqule imisebenzi ye-metabolic yento ephilayo.".
Kulolu cwaningo, abacwaningi bahlaziye ubudlelwano phakathi kwenkomba yesisindo somzimba kanye nokuhlukahluka kwezikhathi zokudla ngempelasonto uma kuqhathaniswa nezinye izinsuku. Basebenzise umaka omusha ohlanganisa izinguquko ezikhathini zokudla (ibhulakifesi, isidlo sasemini, nedina) ngezimpelasonto: ukudla i-jet lag, igama elisungulwe kulolu cwaningo.
«Imiphumela yethu ikhomba lokho ukushintsha izikhathi zokudla okuthathu ngezimpelasonto kuhlotshaniswa nokukhuluphala ngokweqile. Umthelela omkhulu ku-BMI ungenzeka uma sinomehluko wesikhathi wamahora angu-3 noma ngaphezulu. Kusukela kuleli qophelo, yilapho ingozi yokukhuluphala ingakhula khona".
Kukhona ikhefu phakathi kwesimiso somzimba kanye nesomphakathi
Ukuchaza ubudlelwano phakathi kokudla i-jet lag nokukhuluphala, abacwaningi baphakamisa ukuthi impelasonto ngayinye abantu bakhanyiselwe. ukuphazamiseka kwe-chronodisruption, okuwukuntuleka kokuvumelanisa phakathi kwesikhathi sangaphakathi sezinto eziphilayo kanye nesomphakathi.
«Iwashi lethu lebhayoloji lifana nomshini, futhi ngenxa yalokho lilungiselelwa ukuvusa impendulo efanayo yomzimba noma ye-metabolic ngesikhathi esifanayo sosuku, zonke izinsuku zeviki. Amashejuli okudla nokulala achaziwe asiza ekugcineni ukuhleleka kwesikhashana komzimba futhi akhuthaze i-homeostasis yamandla. Ngakho, abantu abanoshintsho olukhulu lwamashejuli bangase bathambekele kakhudlwana ekubeni nesisindo ngokweqile nokukhuluphala".
«Ngaphezu kokudla nokuzivocavoca, okuyizinsika ezimbili ekwelapheni ukukhuluphala, kufanele kucatshangelwe izici ezifana nokujwayelekile ngezikhathi zokudla, njengoba sesiqinisekisile ukuthi kunomthelela esisindweni somzimba wethu.«.eating jet lag
