Ubisi ngenye yezinto ezibaluleke kakhulu ekudleni kwabantu abaningi emhlabeni. Libhekisela emikhiqizweni yokudla ehlukene ngamakhemikhali ngokwezibalo zabo zamakhemikhali. Imiphumela yocwaningo lwesayensi ibonisa ukuthi ebisi kunamakhemikhali angaphezu kuka-50 asebenzayo okuletha izinzuzo ezibonakalayo emzimbeni womuntu. Ubisi bucebiswa ngalezi zakhi ezincane ezincane ezifana ne-phosphorus, i-magnesium, i-sodium, isulfure, i- calcium nama-salts ahlukahlukene emvelaphi yemvelo.
Ngaphezu kwalokho, i-zinc, i-selenium, i-iodine, i-lactic acid nezinye izinto eziwusizo zikhona kulo mkhiqizo ngenani elikhulu. Kukhona izinhlobo eziningi zobisi, futhi ngamunye wabo uhlukile ngemingcele eminingana eyisisekelo echaphazela umthengi wayo nezici zokunambitha. Uyabathinta futhi nendlela umkhiqizo wakhiqizwa ngayo. Okuvamile kakhulu futhi okuvame ukusetshenziswa ekudleni ubisi lwezinkomo. Okuthandwa kakhulu ngumkhiqizo ofana nobisi obisikiwe. Lokhu kungenxa yomdlandla omkhulu wokudla okunempilo. Igama elithi "ubisi oluphekwe" liqondwa ukuthi lisho umkhiqizo onomuthi omncane wobisi obisiwe ekubunjweni kwawo.
Ukwakhiwa kobisi obumhlophe
Izingxabano ngalezi zinzuzo kanye nokulimala emzimbeni wobisi lwe-skim azipheli kuze kube manje. Imibono yabososayensi yahlukaniswa yaba izingxenye ezimbili. Ezinye ziqinisekisa izinzuzo zalo mkhiqizo, zichaza ukuba khona kwazo ekubunjweni kobisi odoba amakhemikhali namavithamini asebenzayo ephilayo. Ngenxa yokuqukethwe kwekhalori ephansi ye-milk skim, ingafakwa ngokuphepha kwimenyu yokudla. Ngokwesilinganiso, i-100.8 kilogram yama-akhawunti womkhiqizo we-30.8 kilocalories.
Kodwa, njengoba bethi "akuzona zonke izinto igolide eligcwala." Ososayensi abaningi baphikisana nokusebenzisa ubisi olunamafutha aphansi, ikakhulukazi ngokucabangela ubuchwepheshe bokukhiqizwa kwawo. Phakathi nokusetshenziselwa izinto zokuqala zangempela ekubunjweni kwamakhemikhali ngobisi obumhlophe akukho mafutha obisi abalulekile. I- vithamini ecebile yeqembu A no-D, iyasiza umzimba ukuba uthathe i-calcium namaprotheni. Ukuqhubeka kulokhu, ososayensi bafinyelela esiphethweni sokuthi ngokusetshenziswa okuvamile kwesibisi sokudla, ukudlala amavithamini kungabonakala.
Imikhiqizo yobisi ephansi kakhulu
Uma ulandela ukudla, khona-ke ukusetshenziswa kwemikhiqizo yobisi oluvutshiwe kuyoba kufanelekile. Zihlukaniswa ngokuqukethwe kwazo kwekhalori ephansi, zithuthukisa ukugaya futhi zicebile ezintweni eziwusizo. Ukukhetha kuleli cala phakathi kwe-kefir ne-fat content ye-1% ne-kefir enomthelela wamafutha we-2.5%, wena-ke, ukhetha ukhetho lokuqala. Ngokusobala, lapho ukudlala ukudla kungcono ukusebenzisa i-kefir ngamaphesenti amancane wamafutha. Inkinga kuphela ukuthi inani lamakholori e-yogurt enjalo ahluke ngempela kulokho okuqukethwe kwamanoni kunkulu. Imikhiqizo yobisi ephansi kakhulu ayinakusiza kakhulu empilweni, ngoba ibuhlungu kakhulu emzimbeni ngenxa yokuntuleka kwamafutha ebisi kuwo. Ngaphezu kwalokho, zingaphansi futhi zinambitha.
Lokhu akusebenzi nje kuphela ku-yogurt, kodwa futhi ku-cottage ushizi. Ngenani lamakholori e-fat-fat curd ne-cottage shizi ngephesenti
Okubalulekile ukuthi ukusebenzisa imikhiqizo yobisi oludwetshiwe, ulahla umzimba we-carbohydrate, amafutha namaprotheni ayadingeka ukuba asebenze.
Iqiniso lokuthi imikhiqizo yemvelo, okuqukethwe okunamafutha okunciphisa, kuzuzisa empilweni, akunakuphikwa. Kodwa ukwenza ngokweqile uma uwasebenzisa akufanelekile. Naphezu kokuqukethwe kwekhalori ephansi yobisi lwe-skim, umzimba wakho ungabhekana nezinhlanganisela ezihlukahlukene zamakhemikhali.
