Zaka zoposa zisanu zapitazo, asayansi apeza kuti kudya nyama yokazinga - kuphatikizapo chops chokazinga, nyama yokazinga ndi nyama yowotcha - kumawonjezera kwambiri chiopsezo cha khansa ya m'matumbo.
Izi ndichifukwa choti ma heterocyclic amines, omwe amawonekera mu nyama yophikidwa kwambiri, amasokoneza kagayidwe kake. Komabe, malinga ndi kafukufuku waposachedwapa wachipatala, mkhalidwe wa nyama yokazinga ndi woipa kwambiri kuposa momwe ankaganizira poyamba.
Kuphatikiza pa khansa ya m'mimba, imayambitsanso matenda a shuga ndi dementia, ndiko kuti, imakhala ndi zotsatira zofanana pa thupi monga zakudya zokonzedwa bwino, "zamankhwala" ndi "zofulumira", kapena chakudya chomwe chaphikidwa molakwika. Madokotala ali otsimikiza kuti mwayi wokhala ndi matenda oopsa, osasinthika umawonjezeka molingana ndi kuchuluka kwa momwe munthu amadya zakudya zotere - kaya ndi burger wodzaza ndi zoteteza kuchokera ku chakudya chamadzulo kapena nyama "yakale" yokazinga kwambiri.
Kafukufukuyu adachitidwa ndi Icahn School of Medicine ku New York ndipo adasindikizidwa mu magazini ya sayansi yaku America Proceedings of the National Academy of Sciences. Zotsatira zikuwonetsa kuti nyama iliyonse yokazinga kwambiri (kaya yokazinga kapena yokazinga) imalumikizidwa mwachindunji ndi matenda ena oopsa - matenda a Alzheimer's.
Mu lipoti lawo, madokotala anafotokoza mwatsatanetsatane njira ya maonekedwe a otchedwa AGE pa kutentha kutentha kwa nyama, "Advanced Glicated End products" (Advanced Glicated End products, kapena AGE mwachidule - "zaka"). Zinthuzi sizimaphunziridwabe pang'ono, koma asayansi atsimikiza kale kuti ndizovulaza kwambiri thupi ndipo zimachititsa matenda aakulu, kuphatikizapo matenda a Alzheimer's ndi senile dementia.
Asayansi anayesa mbewa za labotale, gulu limodzi lomwe linadyetsedwa zakudya zapamwamba kwambiri za glycation end products, ndipo gulu lina lidadyetsedwa zakudya zokhala ndi zocheperako za AGE zovulaza. Chifukwa cha kugayidwa kwa chakudya "choyipa" mu ubongo wa mbewa "zodya nyama", panali kudzikundikira kodziwika kwa mapuloteni owonongeka a beta-amyloid - chizindikiro chachikulu cha matenda a Alzheimer omwe akubwera mwa anthu. Panthawi imodzimodziyo, thupi la mbewa zomwe zimadya chakudya "zathanzi" zinatha kulepheretsa kupanga chinthu ichi panthawi yosakaniza chakudya.
Gawo lina la kafukufukuyu lidachitika kwa odwala okalamba (opitilira zaka 60) omwe akudwala dementia. Ubale wachindunji wakhazikitsidwa pakati pa zomwe zili mu AGE mu thupi ndi kufooka kwa luntha la munthu, komanso chiopsezo cha matenda a mtima. Dr. Helen Vlassara, yemwe anatsogolera zoyesayesazo, anati: “Kupeza kwathu kumasonyeza njira yosavuta yochepetsera ngozi ya matenda ameneŵa ndiyo kudya zakudya zocheperapo m’zaka za m’ma AGE. Mwachitsanzo, ichi ndi chakudya chophikidwa pa kutentha kochepa ndi madzi ambiri - njira yophika yomwe yadziwika kwa anthu kwa zaka mazana ambiri.
Asayansi adaganiza zoyika matenda a Alzheimer's ngati "Type XNUMX Diabetes" pano. mtundu uwu wa dementia umagwirizana mwachindunji ndi kuwonjezeka kwa shuga mu ubongo. Dr. Vlassara anamaliza kuti: “Kufufuza kwina n’kofunika kuti tipeze kugwirizana kolondola pakati pa AGE ndi matenda osiyanasiyana a kagayidwe kachakudya ndi a minyewa. (Pakadali pano, tinganene chinthu chimodzi - Wamasamba) ...
Chifukwa chabwino choganizira kwa iwo omwe amalingalirabe "chakudya chathanzi" chopangidwa bwino, ndipo nthawi yomweyo amakhala ndi luso loganiza bwino!
