Ukususela kumaxesha amandulo, abantu baye basebenzisa ubusika ukuze baphathe iintlobo ezahlukeneyo zezifo. Amaziko asebekhulile aseMandulo aseRussia aqukethe inani elikhulu lokupheka ngokusebenzisa ubusi. Okwangoku, izakhiwo zezokwelapha zezinyosi zezinyosi zifundwa ngokwaneleyo, kwaye le nkcazelo isetyenziswe ngabantu abaninzi ukukhusela kunye unyango lwezifo ezininzi. Nangona kunjalo, umntu kufuneka aqonde ukuba inyoko iyindlela yokwenza unyango olungabalulekanga, olwenza ukuba kubekho umgangatho we-physiology yomzimba womntu, kwaye ukuwusebenzisa ngokufanelekileyo kunye nezinye iindlela.
Ngokwakheka ubusi, kukho izinto ezinamakhulu amathathu, ii-60-80% ze-carbohydrate, malunga ne-20% yamanzi kunye no-10-15% kwezinye izinto. Iinjongo eziphambili zobusi zi-fructose (33-42%) kunye ne-glucose (30-40%). Zibaluleke kakhulu kubantu njengezinto zamandla okutya kunye nokungenelela kwigazi ngokuqhelekileyo ngaphandle kokugonywa kwangaphambili ngamalungu okutya. I-Sugar, esiyidla imihla ngemihla, kufuneka iqale ihlukaniswe kwi-glucose kunye ne-fructose, oko kukuthi, ishukela elula. Ngoko ke, ukusebenzisa ubusi kunceda kakhulu kubantu abanesifo sokukhubazeka kunye nesifo sikashukela.
Iipropati zobusi
I-glucose, equlethwe ngobusi, inokukhawuleza ukuzalisa ukungabi namandla emzimbeni, okubangelwa kukuzikhandla komzimba. I-glucose inokufumaneka kwigazi emva kwemizuzu emibini emva kokuyidla imveliso. I-Fructose iphinda iqokelele esibindi ngesimo se-glycogen, ephendukela kwi-glucose njengoko kufuneka. I-Acetylcholine, nayo inxalenye yobusi, i-neurotransmitter elawula ukusebenza kweeseli zesisindo; ichaphazela inkqubo ye-nervous and autonomic system, ikhuphe uxhaphazo lwentloni nokuphumula. Ndiyabulela i-fructose kwisibindi, isitoreji se-glycogen siphucula. Ngexesha elifanayo, i-choline, equkethwe ubusi, inqanda ukukhuluphala kwesibindi. I-Fructose kunye ne-glucose inikezela ngamandla angaphezulu kwintliziyo. I-Acetylcholine inokuphucula umsebenzi wentliziyo. Ukuba inani legazi linyanyiswa yintliziyo landa, i-pulse iya kuba yinto encinci.
Ekubanjwe ngobusi (ubuninzi bezinto zonke ezinobumnyama), njenge-magnesium, i-cobalt, isinyithi, ubhedu kunye namavithamini eqela leqela B, uncedo luvuselela ukuveliswa kweeseli ezibomvu zegazi (iiseli zegazi ezibomvu). Kwakhona, ngenxa yokuba ubusi bunepropati ye-hygroscopicity kunye nexinzelelo olukhulu lwe-osmotic, liyakwazi ukukhubaza izilonda ezivulekileyo, kwaye zikhusela izifo kunye nokunceda ukuhlamba amanxeba.
Ubusi luyimveliso enomsoco. Iingamakhulu amabini ezininzi zobusi ngenxa yesondlo zilingana nama-250 kernels of walnut, i-200 g ye-fatty cheese, i-500 g ye-beluga, i-500 g yeoli yeentlanzi okanye i-350 g yenkomo yomhlaba. Iqukethe iinkalo ezininzi zeemichiza ukuba umzimba wethu udinga ukusebenza ngokufanelekileyo. Umzimba womntu uthatha ubusi ngokupheleleyo (ngokubhekiselele- inyama inomzimba ngama-95%, ubisi ngo-90%, isonka se-rye nge-85%, iitatata ngo-90%, isinkwa sengqolowa ngama-96%). I-kilogram enye yobusi iqulethe i-3100 khalori. Kubantu abadala, umgangatho wemihla ngemihla ungama-100-150 g, kubantwana 40-50 g. Amanyathelo angaphezu kwezi migaqo ayinconywanga, ingakumbi ngokusetyenziswa kwexesha elide.
Kukho iinkcukacha ezininzi ekusebenziseni ubusi kwizinto zokutya kwasebuntwaneni kumandulo (enye yeyona ndlela imdala ibuyele kwiminyaka eyi-900 BC). Kakade e-China yakudala kwakukholelwa ukuba ubusi banda amandla, uqinisa amandla, uvuselela zonke izitho zangaphakathi, utshise amafutha. EYiputa yaseYiputa, unobomi wanikelwa ezikolweni - kwakukholelwa ukuba abo badla ubusi, bakhula ngokukhawuleza ngokwengqondo nangokwenyama. E-Spain, u-honey usetyenziso olongezelelweyo kubambele abancinci bebisi, ekhonza njengendlela yokugcina impilo yeintsana kunye neentsana ezizalwe ngaphambi kokuzalwa, kwakunye nabantwana abafumene i-jaundice okanye i-anemia ye-hypochromic. Kuphawulwe ukuba ubusi bangela ukuba ukwanda komlinganiselo womntwana kunye nokwanda kwenani le-hemoglobin egazini, kunye nokuphucula kwesondlo somntwana kunye nesiphumo esihle kwiimeko zesisu.
