Eminyakeni engaphezu kwemihlanu eyedlule, ososayensi bathole ukuthi ukusetshenziswa kwenyama ethosiwe - okuhlanganisa nama-deep-fried chops, inyama eyosiwe kanye nenyama eyosiwe - kwandisa kakhulu ingozi yomdlavuza wamathumbu.
Lokhu kungenxa yokuthi i-heterocyclic amines, evela enyameni ephekwe ngokweqile, iphazamisa umzimba ojwayelekile. Nokho, ngokocwaningo lwakamuva lwezokwelapha, isimo senyama ethosiwe sibi kakhulu kunalokho okwakucatshangwa ngaphambili.
Ngaphandle komdlavuza wesisu, ubuye ubangele isifo sikashukela kanye nokuwohloka komqondo, okungukuthi, cishe unomphumela ofanayo emzimbeni njengokudla okucutshungulwe kakhulu, “amakhemikhali” kanye “okusheshayo,” noma ukudla okuphekwe ngokungalungile. Odokotela bayaqiniseka ukuthi amathuba okuba nezifo ezinzima nezingenakulungiseka akhuphuka ngokulingana nokuthi umuntu ukusebenzise kangaki ukudla okunjalo - kungaba ibhega efakwe izinto ezilondolozayo ezivela esidlweni sakusihlwa noma isiteki esithosiwe “esidala” esijulile.
Ucwaningo lwenziwe yi-Icahn School of Medicine eNew York futhi lwanyatheliswa kumagazini wesayensi waseMelika i-Proceedings of the National Academy of Sciences. Imiphumela ikhombisa ukuthi noma iyiphi inyama ethoswe kakhulu (kungaba epanini noma eyosiwe) ihlotshaniswa ngqo nesinye isifo esiyingozi - isifo i-Alzheimer's.
Embikweni wabo, odokotela bachaza ngokuningiliziwe indlela yokubonakala kwalabo okuthiwa ama-AGE ngesikhathi sokwelashwa okushisa kwenyama, "Imikhiqizo Ethuthukisiwe Ye-Glicated End" (Imikhiqizo Ephezulu Ye-Glicated End, noma i-AGE okwesikhashana - "iminyaka"). Lezi zinto zisacutshungulwa kancane, kodwa ososayensi sebevele beqinisekile ukuthi ziyingozi kakhulu emzimbeni futhi zibangela izifo ezinzima ezingalapheki, okuhlanganisa nesifo i-Alzheimer's kanye nokuwohloka komqondo.
Ososayensi bazama amagundane aselabhorethri, iqembu elilodwa elanikezwa ukudla okuphezulu emikhiqizweni yokugcina ye-glycation, kanti elinye iqembu laphakelwa ukudla okunokuqukethwe okuncishisiwe kwama-AGE ayingozi. Njengomphumela wokugaya ukudla “okubi” ebuchosheni bamagundane “adla inyama”, kwaba nokunqwabelana okuphawulekayo kwamaprotheni e-beta-amyloid eyonakele – inkomba eyinhloko yesifo i-Alzheimer’s esisondelayo kubantu. Ngasikhathi sinye, umzimba wamagundane adla ukudla “okunempilo” wakwazi ukunqanda ukukhiqizwa kwale nto ngesikhathi sokwenziwa kokudla.
Enye ingxenye yocwaningo yenziwa ezigulini esezikhulile (ezingaphezu kweminyaka engama-60 ubudala) ezihlushwa ukuwohloka komqondo. Ubuhlobo obuqondile busungulwe phakathi kokuqukethwe kwe-AGEs emzimbeni kanye nokubuthakathaka kwamakhono obuhlakani bomuntu, kanye nobungozi besifo senhliziyo. UDkt. Helen Vlassara, owahola lolu cwaningo, wathi: “Ukuthola kwethu kukhomba endleleni elula yokunciphisa ingozi yalezi zifo iwukudla ukudla okungaphansi kweminyaka yobudala. Isibonelo, lokhu ukudla okuphekwe ngokushisa okuphansi namanzi amaningi - indlela yokupheka eyaziwa esintwini amakhulu eminyaka.
Ososayensi baze bahlongoza ukuhlukanisa isifo i-Alzheimer's njenge "Type XNUMX Diabetes" manje. lolu hlobo lokuwohloka komqondo luhlobene ngokuqondile nokwanda kwamazinga kashukela ebuchosheni. UDkt. Vlassara waphetha: “Kudingeka ucwaningo olwengeziwe ukuze kutholakale ukuxhumana okunembile phakathi kwama-AGE nezifo ezihlukahlukene zokuguquguquka komzimba nezinzwa. (Okwamanje, kungashiwo into eyodwa – Odla imifino)…ngokunciphisa ukudla okunothe ngo-AGE, siqinisa indlela yokuzivikela yemvelo ngokumelene nesifo i-Alzheimer kanye nesifo sikashukela.”
Isizathu esihle sokucabanga kulabo abasacabangela i-chop eyenziwe kahle "ukudla okunempilo", futhi ngesikhathi esifanayo bagcina ikhono lokucabanga ngokujulile!
