Abalimi abaningi bezinkukhu bakholelwa ukuthi ukuphakama kwezinga lokuzala kwamaqanda ebusika bawo nyaka, kungcono. Eqinisweni, lo mbono awuhambisani nesayensi ngoba uma izinga lokuzalela kwamaqanda lezinkukhu ezisanda kukhiqizwa lidlula ama-60% ebusika, ukwenzeka kokumisa ukukhiqizwa nokuncibilika kuzokwenzeka entwasahlobo yonyaka olandelayo lapho kulindeleke ukuthi iqanda libeke phezulu. Ikakhulukazi kulezo zinkukhu zohlobo lweqanda ezinhle zohlobo lwezinkukhu, ngesikhathi sentwasahlobo lapho ziqoqa amaqanda azalela kanye nokuzalanisa amatshwele, kuzoletha ubunzima ekuzaleni izinkukhu ezizalanisa kahle kakhulu futhi kuthinte izinzuzo zezomnotho. Ngisho noma izinkukhu ezisanda kukhiqizwa zingayeki ukukhiqiza entwasahlobo, kuzoholela ekugxilweni kwamaprotheni amancane kanye nezinga eliphansi, okuzophazamisa izinga lokuchanyuselwa kanye nezinga lokusinda kwamatshwele. Ngakho-ke, kuhle kakhulu ukulawula izinga lokukhiqizwa kwamaqanda ebusika ezinkukhu ezisanda kubekwa phakathi kuka-40% no-50%.
Indlela eyinhloko yokulawula i-izinga lokukhiqiza amaqandayezinkukhu ezintsha ukulungisa isilinganiso samaprotheni nama-carbohydrates ekudleni. Ngaphambi kokubekela amaqanda, okuqukethwe kwamaprotheni ekudleni kwezinkukhu ezintsha kufanele kugcinwe ku-16% ~ 17%, futhi amandla e-metabolic kufanele agcinwe ku-2700-2750 kcal/kg. Lapho izinga lokukhiqizwa kwamaqanda ezinkukhu ezintsha lifinyelela ngaphezu kwama-50% ebusika, okuqukethwe kwamaprotheni ekudleni kufanele kwehliswe ku-3.5% ~ 14.5%, futhi amandla e-metabolic kufanele akhuphuke abe ngu-2800-2850 kcal/kg. Maphakathi nasekupheleni kukaJanuwari wonyaka olandelayo, okuqukethwe kwamaprotheni ekudleni kufanele kukhushulwe ku-15.5% kuya ku-16.5%, futhi amandla e-metabolic kufanele ehliswe abe ngu-2700-2750kcal/kg. Lokhu akugcini nje ngokwenza i-izinkukhu ezintshaukuqhubeka nokukhula nokuvuthwa, kodwa futhi kwandisa ukukhiqizwa kwamaqanda, okwenza kube ngcono ukuzalanisa nokuthuthukiswa kwezinkukhu ezinhle zokuzalanisa ngonyaka ozayo.
