Ishukela yokuqala, yaqala ukufumana iminyaka emininzi ngaphambi kwexesha lethu, eIndiya. Yenziwe ngotyhu. Kwangexesha elide, bekuphela iswekile esaziwa ngabantu. Kuze kube ngoku, ngo-1747 umkhandi wenzululwazi waseJamani u-Andreas Sigismund Marggrave akazange athi ingxelo yokufumana ushukela kwi-beetroot kwintlanganiso ye-Academy of Sciences yasePrussia. Nangona kunjalo, ukuveliswa kwefotyi ye-beet kwathatha kuphela ngo-1801, kwaye oku bekuyi-revolution kwimveliso yokutya. Ekubeni, ukususela ngeli xesha, iswekile sele ifikeleleke ngakumbi kwaye ifikeleleke, iifomentshi ezidliwayo ezinqabileyo ziye zagqithiswa kwinqanaba lokutya kwansuku zonke. Iziqhamo ezibuhlungu zale nto ziyaziwa sonke kuthi - izifo zamazinyo kunye nokukhuluphala sele kube yingxaki yangempela kweli hlabathi lanamhlanje.
Yintoni ushukela?
I-Sugar ifumaneka kwifom ecocekileyo i-sucrose - i-carbohydrate, eyenziwa emzimbeni wethu ibe yi-glucose kunye ne-fructose kwaye ibhekisela kuma-carbohydrate "ngokukhawuleza." Inkcazo ye-glycemic ishukela i-100. I-Sugar iyinamandla angcolileyo, ayiyingozi okanye ayizuzi, njengenjalo, ayithwali ngokwayo. Iingxaki ziqala xa sifumana amandla amaninzi kunokuba sinokuphinda sisebenzise kwakhona. Cinga oko kwenzekayo xa ushukela ungena emzimbeni wethu. Ukutshiza i-sucrose kwenzeka kwi-intestine encinane, apho i-monosaccharides (i-glucose kunye ne-fructose) ingena egazini. Emva koko isibindi, apho i-glucose idluliselwa kwi-glycogen - indawo yokugcina amandla "kwimihla yamvula", ebuye isetyenziswe kwakhona kwi-glucose, ithatyathwa kwimeko. Ukuba, ubungakanani beshukela budlula ubuninzi obuyimfuneko, obungaguqulelwa kuba yi-glycogen, ngoko-insulin iqala ukusebenza, idlulisela ishukela kwiivenkile zezilwanyana zomzimba. Kwaye ukuchitha amanqatha, umzimba wethu ongawuthandayo, ukusuka apha - ubunzima obuninzi, ubunzima. Ukongezelela, ukuba kukho ishukela enkulu ekudleni, ngoko uvakalelo lweeseli ukuya kwi-insulin yehla, akanako ukuthutha i-glucose engaphezulu kwiiseli, ezikhokelela ekunyuseni okunyukayo kumanqanaba eshukela egazi, kwaye emva koko kunokubangela uhlobo lwesifo sikashukela.
Kodwa ukungabikho kwe-carbohydrates kuyingozi. Umzimba kufuneka uthathe amandla ukusuka kwenye indawo. Ngoko ke, kufanelekile, mhlawumbi, kungekhona ukuthetha ngengozi okanye inzuzo yeshukela, njengaloo nto, kodwa malunga nokusetyenziswa kwayo okufanelekileyo.
Izityalo zeshukela - ezilungileyo nezimbi
Isithelo ishukela, okanye i- fructose - isondlo esisondeleyo se-glucose, kodwa ngokungafani nayo, ayifuni i-insulin ekusebenziseni kwayo, ngoko ingasetyenziswa kwizigulane zesifo sikashukela. Nangona kunjalo, nangona i-fructose inokuthi iqhutywe ibe ngamafutha, ayibangele ingqiqo yokunyamekela, ngoko iyakwenza inxaxheba ekuphuhliseni ukunyanya. Iqukethe i-fructose, kungekhona nje kwiswekile kuphela, kodwa kwiziqhamo ezininzi, ngokubonga, kwaye igama layo.
Iswekile yamagilebhisi ilungile kwaye imbi
Iswekile yamagilebhisi kuthiwa yi-glucose. Le yinqumle ye-carbohydrate, ethatha inxaxheba kumandla omzimba womzimba womntu. Iinzuzo kunye neengozi zeeshukela zediliya ziyahlukahluka kwi-ushukela evamile. Inobungozi ibangelwa yinkqubo yokwenza i-caries kunye ne-fermentation iinkqubo, ezinokuphazamisa i-microflora.
Isityalo seshukela lilungile kwaye libi
Ishukela yokuqala eyaziwayo kuluntu. Ikhishwe kwimixoke. Ngokwakheko, phantse kufana ne-sugar beet kwaye iqukethe i-99% ye-sucrose ukuya kuma-99%. Iipropati zeeshukela zifana nezo zihambelana neetroet.
Ishukela lepalm lilungile kwaye libi
Itholakala ngokumisa umsi womhla, ikonati okanye isundu sesundu. Imveliso engapheliyo, ngoko ke ithathwa njengenye indlela enempilo kwimihla yendabuko yeswekile. Ukuba sithelekisa le shukela kunye nezinye iindidi, ngoko sinokuthi akukho nto.
