Abaninzi abafazi abathandi ukuchitha ixesha ukulungiselela izitya zentlanzi. Enyanisweni, okokuqala, kufuneka uhlambulule intlanzi kwisilinganisi esincinci seesilinganisi, ukuyiginya, kwaye ukukhusela isikhumba sezandla zakho ukuba ungayithinteli i-spikes ebukhali eentlobo ezininzi zeentlanzi. Nangona kunjalo, zonke ezi zinto zingabonakali kakhulu iimveliso zokutya ziza kuhlawula ixabiso eliphezulu lokusetyenziswa kwemveliso yeentlanzi kumzimba wethu. Ukufakela izitya zeentlanzi kwimenyu kuyimfuneko nje yokondlo olufanelekileyo. Ziziphi iimpawu zentengiso yeentlanzi ezenza zibaluleke kakhulu ekudleni kwethu?
Inyaniso kukuba izondlo eziqulethwe kwiintlanzi zinika oku kutya ukutya okuphezulu. Izinxalenye ezidliwayo zeentlanzi zibonakaliswa ngumxholo ophezulu weeprotheni eziphezulu (inani labo ngokulinganisa lifikelela kuma-17-19% ubuninzi beethambo), kwaye kulezi proteins, ngendlela efanelekileyo, ngokuhambelana neemfuno zomzimba wethu, ukubunjwa kwe-amino acid kulinganayo. Ngokomzekelo, xa kuthelekiswa nomzimba, kwiintlanzi zeentlanzi kuninzi kakhulu i-amino acid methionine. Olunye uphawu olubalulekileyo lweemveliso zentlanzi ngumlinganiselo omncinci wezicubu ezinxibelelwano. Ngaloo nto, emva kokunyanga kwentsholongwane, intlanzi ephekiweyo iyaba yinto ethambileyo kwaye iyinyameko, eqinisekisa ukutya kakuhle kweentlanzi kwi-tract of human tract.
Umxholo wamafutha kwiintlanzi zeentlanzi zisuka kwi-0.5 ukuya kwi-30%. Esi sibonakaliso sibonakaliswa ngokungafani ngokukodwa, kuxhomekeke kwiintlobo zeentlanzi, ubudala, isondlo, amaxesha. Ukusetyenziswa kweemveliso zentlanzi kubantu abaqeqeshwe ngokufanelekileyo kunye nalabo abafuna ukulahlekelwa ngamapounds angaphezulu kunqunywe ukuba ininzi yeentlobo (umzekelo, i-pollock, i-cruci carp, i-burbot, i-perch, i-pike, i-pike) iqulethe kakhulu i-fat, kodwa ngexesha elifanayo liba nenani elikhulu lamaprotheni alambileyo zethu izihlunu. Kwinqanaba elinqwenelekayo leoli linalo inhlanzi njenge-pink salmon, i-carp, i-bream, i-hertic herring, i-catfish, i-horse mackerel, i-sprat. Kodwa kwiintlanzi iintlanzi ezenziwe kwi-salum, i-sturgeon, i-halibut, i-sardine, i-sturgeon stellate, i-eel, i-mackerel kulabo abafuna ukunciphisa ubunzima, umxholo we-fat will be unacceptable. Ukuba inani lakho sele lilungele kakuhle, ukutya inani elincinci leemveliso zentlanzi ephezulu liza kunceda umzimba wakho kuphela. Inyani kukuba ukubunjwa kweoli yeentlanzi kubandakanya i-acids e-insaturated essential acids. Ezi zinto zibonakaliswe ngento yokuba zinemiphumo emihle kwi-cholesterol metabolism, inika izinga eliqhelekileyo lokuqhawula ngegazi kunye neengcinezelo zobisi kwi-atherosclerosis kunye nomfutho wegazi. Ukongezelela, ioli equlethwe kwiimveliso zentlanzi inotye kwiivithamini ze-vitamin A kunye noD.
Iimveliso zentlanzi ezenziwe kwizilwanyana zaselwandle zinomxholo omkhulu wezinto ezifunekayo kumsebenzi oqhelekileyo womzimba wethu - zinc, ithusi, i-fluorine, iodine. Kodwa zikhona ezimbalwa izicatshulwa kwiintlanzi zeentlanzi kunokutya, kodwa zisebenza ngokugqithiseleyo kumsebenzi weengqungquthela zokufihla ukutya. Naphezu kweenzuzo zempilo kunye neempawu eziphezulu zokutya eziyimpawu eziphathekayo zeemveliso zentlanzi, oku kukutya kusalugxininiswa ngamalungu ethu okutya. Ngokomzekelo, iintlanzi ezomileyo nezomisiwe zitsalwa kakhulu kunokuba zifakwe okanye zibiliswe.
Ukusetyenziswa kweemveliso zentlanzi kwimpilo yakho kuya kugqitywa ngoluhlobo olutsha oluthengiweyo. Ukuze ukhethe intlanzi efanelekileyo kwivenkile ukuze ulungiselelwe izitya ezifanelekileyo ngokwenene, kufuneka uqaphele ezi zinto zilandelayo mveliso. Kwientlanzi ezitsha, amehlo kufuneka abe ne-convex, ene-cornea ebonakalayo. Iimpawu ze-muscular zeentlanzi ezinobungozi zinemibala eninzi kwaye imhlophe imhlophe, kunzima ukuhlukana namathambo. Xa upheka umhluzi weentlanzi kufuneka ubanjwe iphunga elimnandi, kwaye umhluzi uphenduka obala. Ukuba intlanzi efunyenweyo ineempawu ezinje ezinjengezikhwebu ezibomvu, zithinteka kalula emathanjeni emisipha, iigrafu ezibomvu ezibomvu kunye nephunga elimnandi elincinciweyo, ngoko ke ukusetyenziswa kwezimbiza zentlanzi ezinokulungiswa kwimveliso enjalo ngokucacileyo kufuneka zibuzwe.
Amaqanda aseentlanzi anokufumana isondlo esiphezulu. Ngokomzekelo, i-caviar ye-salmon kunye ne-sturgeon iintlanzi iqulethe malunga ne-30% yeeprotheni eziphezulu, inani elikhulu le-lecithin, ii-vithamini A, D, E, i-phosphorus, isinyithi, nezinye iimaminerali. I-Caviar ithathwa njengemveliso yentlanzi ephuma kwinqanaba lezinto ezidliwayo kunye neempawu zokutya eziphezulu.
Kodwa intlanzi okanye i-fish ekhutshwe ngamathanga ayiluncedo kakhulu emzimbeni wethu kuneentlanzi ezintsha. Inyani kukuba iinkqubo zobuchwepheshe ezisetyenziselwa ukuveliswa kwezi ntengiso zeentlanzi, ukulahleka okungenakukupheka kwezondlo. Ukutya okusemgangathweni kwenzelwe ukwenziwa kwi-mackerel, i-salmon, i-horse mackerel, i-herring. Ukutya okusemathinini kwi-tomato sauce kwenziwa kwintlanzi edibeneyo kunye neyintlanzi. Intlanzi ekhonkcisiweyo kwinqwelo yeoli ikulungiswe kwientlanzi ezitshisayo okanye ezibiweyo. Iifate kunye neepasta azifumaneki kuphela kwiintlanzi zonke, kodwa nakwi-caviar, isibindi, ubisi kunye nenye inkunkuma yokutya. Xa wenza intlanzi ekhunjisiweyo, izithako ezinjengentlanzi ye-minced, imifuno ebusiweyo, okusanhlamvu, i-marinade, iziqholo, i-tomato sauce isetyenzisiweyo.
Isalathiso esicacileyo sokugcinwa ngokuthelekiswa nokutya okusemgangathweni kukuba inkqubo yokuveliswa kwawo ayifaki isigaba sokuzalisa inzalo. Ukufumana le mveliso yeentlanzi isebenzisa izilondolozo, ngokuqhelekileyo i-acetic acid okanye i-sodium benzoate. Ngamanye amaxesha kwindlela yokulondolozwa, iipokotshi ezinobisi kunye neentlanzi kunye neeterry.
Iintlanzi ezithengiweyo ezithengiweyo kwiimarike kufuneka zigcinwe ngefriji, kwaye akufuneki ukuba zivunyelwe ukuba zifudumele ngokuphindaphindiweyo (oku kwenza izimo ezilungileyo zokuphindaphinda kweebhaktheriya, zikhokelela ekunciphiseni kwinqanaba lokutya okunomsoco kwemveliso kunye nokuchithwa kwayo). Imveliso yentlanzi enjengokutya okusemgangathweni igcinwa kumaqondo okushisa ukusuka ku-0 ukuya ku-5 ° C kunye nokunyaniseka okuhambelana nomoya akukho ngaphezu kwama-75% ngexesha eliboniswe kwiphakheji (ngamanye amaxesha kwiminyaka emi-2 ukuya kwe-3). Ukugcinwa kufuneka kugcinwe kwiqondo lokushisa elingekho ngaphezu kwe-6 ° C ngaphandle kweentsuku ezi-45.
