Kodi mwagula zakudya ndi zakumwa popanda sitolo? Tsopano iwo akuphimba firiji yonse, ndipo mu makabati ophika kake ndi ma chips ndi mafuta ocheperapo? Chifukwa chiyani simunakwanitse kulemera? Mwinamwake zakudya zimenezi sizinali zofanana ndi zomwe amalengeza?
Yankho lingapezekedwe m'zinthu zotchedwa zakudya zokha. Ku yunivesite ya Cornell ku United States, asayansi adapeza kuti anthu omwe amakonda malonda ndi mawu akuti "zakudya zamagetsi" amadya zakudya zowonjezera 28% kuposa omwe samayesa kulemera, koma amadya chirichonse. Phunziroli linasonyeza kuti chifukwa chake mukamadya zakudya zowonjezera, simukumva kuti ndizolakwa zomwe zimatichenjeza kuti tisamadye kudya. Ngati munganene mosiyana, ndiye kuti mumadya zakudya zamtundu wa zakudya zomwe zimakhala zazikulu kuposa momwe thupi lanu likufunira.
Ngati simukumvetsera kuti mu mafuta opanda mafuta mafuta ochulukirapo, akhoza kukhala ndi zakudya zambiri. Pali malamulo ena, malinga ndi zomwe mankhwalawa sayenera kukhala oposa magalamu atatu a mafuta pa 100 magalamu a mankhwala. Komabe, zonse zomwe zingalowe m'malo mwa shuga ndi zowonjezerapo zimakhala zowonjezera zowonjezera zowonjezera zopangira mankhwala.
Mafukufuku opangidwa mu labotayi amasonyeza kuti chakudya chopanda mafuta chimakhala chimodzimodzi ndi chizoloŵezi, koma kumbali ina chimapangitsa thupi kufuna mafuta ochulukirapo. Mafuta ndi zakudya zokoma amakonzekeretsa thupi lathu kuti zikhale zowonjezera kwambiri. Koma ngati sitipereka izi, ndiye kuti ubongo umalandira chizindikiro kuchokera m'mimba ndi zotsatirazi: "Tiyenera kuyang'ana chakudya mwamsanga!".
Zotsatira zomwe tafotokozazi sizatsopano ayi. Anthu akhala akudziwika kuti anthu ambiri ndi okalamba, omwe amamwa zakumwa ziwiri kapena kuposerapo tsiku ndi tsiku, amakula mafuta m'mimba pamimba mofulumira kuposa omwe amadya chakudya. Chifukwa chiyani ndizosamvetsetseka, koma n'zoonekeratu kuti zakumwa zakumwa zimapangitsa thupi kukhala lofuna ndikusowa shuga.
Asayansi ku Yunivesite ya Yale adalongosola malingaliro awo ponena kuti chakudya chomwe chiri ndi zakudya zambiri ndi mafuta zimakhudza mlingo wa mahomoni. Apanso, iwo amayesa kuyesera komwe gulu la anthu akulu adamwa mkaka wa milkshake, womwe umasonyeza kuti unali ndi mafuta ochulukirapo ndipo unali ndi makilogalamu akulu kwambiri. Pamene anthu ankamwa chakudya, mlingo wa hormonegrelin unachepa kwambiri, ndipo hormone iyi imayambitsa kukwanira. Koma gulu lina la akuluakulu analandira malo omwewo, pokhapokha palemba lomwe iwo analemba kuti liri ndi mafuta pang'ono ndipo ali otsika kwambiri. Pambuyo poyeza mlingo wa mahomoni omwewo - ghrelin yakula kwambiri.
Chotsatira chake ndi chakuti ngati mukufuna kulemera, simukusowa kuyang'ana zakudya zamagulu, koma kudya zakudya zatsopano, zochepa muzinthu zing'onozing'ono.
Kodi muyenera kuchita chiyani?
- Pezani diary chakudya, momwe mungalembere mankhwala onse ndi zochepa za calories ndi mafuta. Yesani kuyerekeza ndi zinthu zachilengedwe.
- Mmalo mwa zakumwa zakumwa zimamwa madzi ochepa amchere kapena carbonated ndi laimu watsopano, madzi a lalanje kapena laimu.
- Monga zakudya zopanda zakudya, idyani zakudya zomwe zili ndi zosakwana 100 calories. Zikhoza kukhala nthochi yaing'ono yamitundu yosawerengeka ya mtedza, kaloti ndi kuwonjezera pa makilogalamu anai a Chigriki tsatsika, kapu yaikulu ya saladi kapena zipatso zochepa. Ndipo muiwale za zakudya zamuyaya!
