Abahinzi mu nkoko guhitamo ibiryo cyangwa ni, ukurikije ubwoko bw’inkoko zitandukanye, imikurire yikibazo cyo guhitamo. Uburyo bwo guhitamo umubiri ukenewe nuburyo bukurikira:

Ibiryo bivangwa nubwoko bwibiryo bifite agaciro kamwe kandi byuzuye byuzuye byintungamubiri ukurikije ubwoko butandukanye, ibyiciro byikura n urugero rwumusaruro wamatungo, inkoko n’amafi, ibisabwa byintungamubiri zitandukanye nibiranga physiologique yibiranga, bihuza ibiryo bitandukanye. ibikoresho fatizo hamwe nibindi byongeweho ukurikije formulaire yumvikana hamwe nubuhanga bwateganijwe bwo gutunganya. Ukurikije formulaire yumusaruro udasanzwe wuruganda rwubwoko bwibiribwa byinganda. Byitwa kandi ibiciro byuzuye byuzuye ibiryo. Ubu bwoko bwibiryo bugizwe ninyongeramusaruro, ibiryo bya poroteyine, ibiryo byintungamubiri nibiryo byingufu. Ifite intungamubiri zuzuye. Igicuruzwa kirasanzwe, gikurikiranwa kandi gisanzwe, kandi imikoreshereze yacyo irihariye. Ubwoko bwose bwamatungo, inkoko nandi matungo ntibishobora kuvangwa; Igihe cyikura gitandukanye, imikorere itandukanye, umusaruro winyamanswa imwe ntishobora kuvangwa.

Ikozwe mubiryo byingufu, ibiryo bya protein nibiryo byamabuye ukurikije formulaire. Ubu bwoko bwibiryo bushobora guhaza ingufu, proteyine, calcium, fosifore, umunyu nizindi ntungamubiri zamatungo n’inkoko. Nyamara, ibintu bifite intungamubiri kandi bidafite intungamubiri, nka acide aminide acide, ibintu bya vitamine, vitamine, antioxydants, imiti yica udukoko, nibindi, ntabwo byongeweho. Ubu bwoko bwibiryo bugomba guhuzwa nigice runaka cyibiryo bitoshye cyangwa ibiryo byongeweho kugirango bihuze imirire y’amatungo n’inkoko. Agaciro k'imirire y'ibi biryo ni byiza cyane kuruta iby'ibiryo bimwe cyangwa “ibiryo byo gukora” (imvange y'ibiryo byinshi n'ibindi bikoresho byajanjaguwe kandi bivangwa uko bishakiye). Arakwiriye kurwego rwigihugu cyacu muri iki gihe ubworozi n’ubworozi bw’inkoko, ni uruganda rutunganya ibiryo byo mu mujyi, umusaruro w’umwuga cyangwa umusaruro wabo bwite w’ibiryo nyamukuru.
