Inyama - umhlinzeki oyinhloko wempahla yamandla emzimbeni wethu, okungukuthi, amaprotheni wesilwane. Kukhona futhi ama-amino acid amaningi atholakala kubakhi - inyama abakhiqizi be-DNA ne-RNA yesisindo ngasinye; kukhona kuwo amavithamini namanye amaminerali adingekayo emsebenzini odidiyelwe womzimba wethu.
Izakhiwo eziwusizo zenyama zisekelwe eqinisweni lokuthi liyisithombo samaprotheni ayigugu, afana ne-tropomyosin, i-actin ne-myosin, ehlinzeka ngezinto zokwelapha ezingenakulungiswa ezingamakhemikhali - amino acid (i-lysine, methionine, tryptophan nabanye).
Okuqukethwe inyama kuyisethi ephelele yama-macronutrients - i-magnesium, i-sodium, i-phosphorus, isulfure, i-potassium, ngamanani amancane we-calcium ne-chlorine. Ngamunye wabo unomphumela omuhle emzimbeni, isibonelo, usizo lwe-potassium ne-magnesium ekwenzeni izimo zesisindo - indlela yokuzimela yenhliziyo yethu iswele kakhulu kubo; Isibabule siyingxenye yama-enzyme amaningi namahomoni; i-phosphorus ne-calcium isiza ukukhula nokuqinisa ama-skeleton.
Inyama iqukethe zonke izingxenye ezintathu (i-sodium, i-potassium ne-chlorine), okudala ibhalansi ye-acid-base emzimbeni wethu. Ngakho-ke, ukuthatha inyama, kusiza ukulawula izinqubo eziningi ezakhiweni nezitho.
Kumele kucatshangelwe ukuthi inyama - umthombo ocebile kakhulu wamavithamini B, obhekene nomsebenzi wesimiso sezinzwa, kubaluleke kakhulu ekuvuselelweni kabusha, kusebenze izinqubo zokusebenzisa umzimba.
Yiluhlobo luni lwenyama oluwusizo kakhulu kumuntu?
Ewusizo ekusetshenzisweni, kubhekwa njengenyama yezinhlobo eziphansi zamafutha. Inyama ewusizo kunazo zonke, inyama yokudla - inyama enogwaja, inokuqukethwe kwekhalori ephansi futhi iqukethe zonke izinto eziwusizo.
Izinhlobonhlobo eziwusizo zibandakanya i-turkey, inyamazane nemifino yehhashi. Laba abameleli bezinyama banamaprotheni nezinto ezibalulekile. I-Veal inempahla eminingi ewusizo, kodwa ibangela ekuqongeni kwe-cholesterol, ngakho-ke ayibiza wonke umuntu.
