Njengokuba kusekwe izazinzulu, igram enye yeoli xa igalelwe emzimbeni kwimveliso yokugqibela (amanzi kunye ne-carbon dioxide) inika amandla kabini kunani elifanayo leprotein okanye i-carbohydrates. Kodwa ngokungekho ngokupheleleyo iifayile zombini kunye nemvelaphi yezilwanyana ekudleni kwayo ayifanelekanga. Inyaniso kukuba xa udla iimveliso ezinamafutha ezivela kwimfuyo, umzimba wethu ufumana into enjalo njenge-cholesterol. Ewe, i-cholesterol efanayo, ebonisa ubuninzi obuninzi yempembelelo kwiimeko zempilo yethu, kwaye ngaphezu kwayo yonke into iphazamisa umsebenzi we-cardiovascular system. Kodwa ungakulibali ukuba le ye-cholesterol enye yezona zinto ziphambili ze-fatabetism emzimbeni womntu. Ngaphandle kokuthabatha inxaxheba kwakhe, kuba nzima ukufeza enye yeyona biosynthesis ebaluleke kakhulu emzimbeni wethu. Ngokomzekelo, ekungabikho kwe-cholesterol, i-hormone ye-steroid ayinakwenzeka, kwaye ukuvela kwezifo ezinjalo ze-hormonal, njengokuba uyazi, kubangelwa yimiphumo emibi kakhulu kwimeko jikelele. Ngoko ke, nangona inani lemfuyo yezilwanyana ekudleni kufuneka libe ncinane kakhulu, akukafaneki ukubabandakanye ngokupheleleyo ekudleni, nangona kukutya kokulahleka kwesisindo. Into kuphela enokukwazi ukuyenza ukuyeka ukusebenzisa amanqatha ngexesha elifutshane kakhulu, umzekelo, ngexesha elithiwa "ukukhulula umhla", xa izitya eziphambili kwitheyibhile yethu ziyimveliso yemifuno okanye imveliso ye-lactic acid.
Ngokuphathelele amafutha emvelaphi yemifuno, umxholo wabo wekhariki uphakamileyo njengento yezilwanyana zezilwanyana. Ukwahlula kwimbonakalo yemifuno yemifuno kwizilwanyana ngokulula: inyaniso kukuba imifuno eninzi yemifuno kwiqondo lokushisa elisebusini iimeko zombuso, kunye nemfuyo yezilwanyana ezivela kuyo. Kodwa omnye ummahluko, obaluleke ngakumbi kwimpilo yethu, uhlala kwimisebenzi eyahlukeneyo yemvelo yale maqela ezinto. Kubonakala ukuba amafutha emvelaphi yemifino anokuqulethwe kwi-organic acid e-unsaturated fatty acids - i-linoleic, i-linolenic ne-arachidonic, eyona nto ibaluleke kakhulu ukugcina impilo yethu. Esi sizathu sokulawulwa kwesondlo, ngokwemizimba yethu kufuneka inike isixa esibalulekileyo samanqatha, kungekhona kuphela kwixabiso lemveliso yezilwanyana, kodwa nangenxa yokutya okunamafutha okuhlaza. Ngendlela, okwangoku kuthengwa kwemifuno yemifuno yindlela ecocekileyo kwiindawo ezahlukeneyo - i-sunflower, umnquma, i-soybean kunye nezinye iifuno zemifuno. Ukuqinisekisa iimfuno zemihla ngemizimba yomzimba kula ma-acid adibeneyo angabhalwanga, iifowuni ezimbalwa zeoyile yemifuno, esiyisebenzisayo xa silungiselela isaladi yemifuno.
Ngaloo ndlela, ukubaluleka kobukho kwindlela yethu yokutya kwamafutha omhlaba wesityalo kunye nesilwanyana kubonakala ngokucacileyo kwaye kuye kwangexesha elide kuqinisekiswa kwinqanaba lezesayensi. Ngoko ke kunye nokutya okuqinileyo ukulahleka kwesisindo, awufanelekanga ngokupheleleyo ngaphandle kokutya okunesondlo ephuma kuluhlu lokutya okudliwe.
