Inqubo efanele yokugaya ingenzeka kuphela esimweni senhlanganisela efanele yemikhiqizo, okungukuthi amaprotheni, amafutha nama-carbohydrates, ngesikhathi esisodwa. Isisu, lapho kuvela khona ukubola kokudla okuxutshwe ngendlela engafanele, ngeke sikwazi ukunikeza umzimba ama-calories namavithamini ayekhona ekuqaleni ekudleni okudliwe.
Esihlokweni sizohlala ngokuningiliziwe ngemithetho eminingana ethize yokudla okuhlukene. Isinkwa, amazambane, uphizi, ubhontshisi, ubhanana, izinsuku kanye namanye ama-carbohydrate akukhuthazwa ngokuqinile ukuthi kudliwe ngesikhathi esifanayo nelamula, umcako, i-orange, i-grapefruit, uphayinaphu nezinye izithelo ezine-asidi. I-enzyme ptyalin isebenza kuphela endaweni ene-alkaline. Ama-asidi ezithelo awavimbeli nje kuphela ukugaya ama-asidi, kodwa futhi akhuthaza ukuvutshelwa kwawo. Utamatisi akufanele udliwe nanoma yikuphi ukudla okunesitashi. Yidle kanye namafutha noma imifino. Izinqubo zokwenziwa kwama-carbohydrate (isitashi noshukela) namaprotheni zihlukile komunye nomunye. Lokhu kusho ukuthi amantongomane, ushizi, imikhiqizo yobisi akuvunyelwe ngesikhathi esifanayo nesinkwa, amazambane, izithelo ezinoshukela, ophaya nokunye. Amaswidi (kanye noshukela ocolisisiwe ngokuvamile) acindezela ukukhishwa kwejusi yesisu ngezinga elikhulu, kubambezeleka kakhulu ukugaya. Zidla ngobuningi, zivimbela umsebenzi wesisu. Ukudla okubili kwamaprotheni emvelo ehlukene (isibonelo, ushizi namantongomane) kudinga izinhlobo ezahlukene zejusi yesisu ukuze zimunce. Kufanele kuthathwe njengomthetho: esidlweni esisodwa - uhlobo olulodwa lwamaprotheni. Ngokuqondene nobisi, kuyinto efiselekayo ukusebenzisa lo mkhiqizo ngokwehlukana nakho konke okunye. Amafutha anciphisa umsebenzi wezindlala zesisu, avimbele ukukhiqizwa kwejusi yesisu ukuze kugaywe amantongomane namanye amaprotheni. Ama-fatty acids anciphisa inani le-pepsin ne-hydrochloric acid esiswini. Ujeli, ujamu, izithelo, isiraphu, uju, ama-molasses - konke lokhu sikudla ngokwehlukana nesinkwa, amakhekhe, amazambane, okusanhlamvu, ngaphandle kwalokho kuzobangela ukuvutshelwa. Ama-pie ashisayo anoju, njengoba uqonda, ngokombono wokudla okuhlukile, awamukeleki. Ama-monosaccharides nama-disaccharides abila ngokushesha kune-polysaccharides futhi avame ukubila esiswini, alinde ukugayeka kwesitashi.
Ngokulandela izimiso ezilula ezibalwe ngenhla, singakwazi ukulondoloza impilo yomgudu wethu wamathumbu kanye nawo wonke umzimba wonke.
