Amaprotheni amancane yinani elincane lamaprotheni elisiza ukugcina ukulingana kwe-nitrogen emzimbeni (i-nitrogen iyinto ebaluleke kakhulu kuzo zonke izinto eziphilayo, njengoba kuyingxenye yazo zonke i-amino acid kanye namaprotheni). Kutholakala ukuthi ngesikhathi sokuzila izinsuku ezingu-8-10 inani lamaprotheni njalo lihlukaniswa emzimbeni - cishe ama-23.2 amagremu (ngomuntu onesisindo esingama-70 kg). Noma kunjalo, lokhu akusho ukuthi ukudla okulinganayo kwamaprotheni okuvela ekudleni kuzokwanelisa ngokuphelele izidingo zomzimba wethu kule nxenye yokudla, ikakhulukazi uma wenza imidlalo. I-protein minimum ikwazi kuphela ukugcina izinqubo eziyisisekelo zomzimba ezingeni elifanele, ngisho nangesikhathi esifushane kakhulu.
Iprotheyini enkulu kakhulu inani lamaprotheni ekudleni okwanelisa ngokuphelele izidingo zomuntu zamakhemikhali e-nitrogen futhi ngaleyo ndlela inikeza izingxenye ezidingekayo emisipha ephulukisayo emva kokuzivocavoca, igcina ukusebenza kahle kwezinto eziphilayo, inomthelela ekwakheni izinga elanele lokumelana nezifo ezithathelwanayo. Iprotheyini enhle yenyama yomfazi omdala ingaba amagremu angu-90 kuya kwangu-100 amaprotheni ngosuku, futhi ngezemidlalo ejwayelekile njalo, lokhu kungakhula kakhulu - kufika ku-130 - 140 amagremu ngosuku nangaphezulu. Kukholelwa ukuthi ukwenza amaprotheni amaningi ngosuku uma wenza umzimba ngokomzimba wekhilogremu ngayinye yesisindo somzimba, isilinganiso sokudla ama-1.5 amagremu amaprotheni nokuningi kuyadingeka. Kodwa-ke, ngisho nasemibuthweni yokuqeqeshwa kunazo zonke ezemidlalo, inani lamaprotheni akufanele lidlule u-2 kuya ku-2.5 amagremu kilogram ngayinye yesisindo somzimba. Uma uhamba emaceleni ezemidlalo noma amaqembu okuzivocavoca enomgomo wempilo kuphela, khona-ke okuqukethwe okunamaprotheni okwanele ekudleni kwakho kufanele kubhekwe njengamanani ayo, okuqinisekisa ukudla okuyi-1.5 kuya ku-1.7 amagremu amaprotheni ngekhilogremu yesisindo somzimba.
Kodwa-ke, ukuhambisana ne-protein encane futhi iphrotheni elihle kakhulu emidlalweni akuyona yodwa isimo sokondla okwanele, okuhlinzeka ngezinqubo zokuvuselela emzimbeni ngemuva kokuqeqeshwa okusebenzayo. Iqiniso liwukuthi amaprotheni okudla angase ahluke ngokuphawulekayo kokudla kwawo okunomsoco. Isibonelo, amaprotheni emvelaphi yezilwane ahle kakhulu emzimbeni womuntu ngokwemigomo yawo ye-amino acid. Zinezo zonke amino acid ezibalulekile ezidingekayo ekukhuleni nasekutholeni okusheshayo kwezicubu zomzimba ezithinta imisipha. Ama-protein aqukethe ukudla okutshalayo aqukethe inani elincanyana kakhulu lamanye amino acid abalulekile noma abonakala ukungabi khona kwezinye zazo. Ngakho-ke, lapho uqhuba imidlalo, ukudla okulungile kuyoba inyama nemikhiqizo yobisi, amaqanda nezinhlanzi.
Ngakho-ke, ngesisekelo sokucabangela amagugu amaprotheni ubuncane kanye neprotein enhle, umuntu kufanele azame ukuhlinzeka umzimba wakho ngezinto ezibaluleke kakhulu ezemidlalo.
