I-Nitrate ikhona ngokuvumelana emvelo futhi akunakwenzeka ukuyiqeda. Lokhu kuyinto ephoqelekile yokudla kwe-nitrogen izitshalo, ngaphandle kokuthi amaprotheni ayinakwenzeka. Ngisho noma umquba ungasetshenzisiwe nhlobo, usaba yi-nitrites, futhi ekugcineni umphumela waba i-ammonia (ukudla okuyisisekelo kwezitshalo).
Ngakho-ke, ukuba khona kwe-nitrate akuyona into embi kakhulu, kepha ukukhululeka kungabangela imiphumela emibi kakhulu. Ngosuku umuntu uvumelekile ukuba adle 300-350 mg nitrate. Ngakho-ke, ungasheshi ukudla ngokweqile ngemifino nezithelo, futhi ngezinye izikhathi ulandele iseluleko sabachwepheshe.
Inani le-nitrate lithinteka yizici eziningana. Phakathi kwabo, akuzona nje ukufaka umanyolo, kepha futhi nezimo lapho izithelo zikhula khona. Izimila zinamakhono ahlukene okuqoqa lezi zinto. Kunamaqembu amathathu:
Unendawo engozini enkulu (ulethisi, beet, isipinashi, iklabishi, i-dill, u-anyanisi oluhlaza, isithombo, ikhabe kanye namakhabe);
Medium (zucchini, itheniphu, ukholifulawa, iklabishi, ukhukhamba, izaqathe, i-horseradish);
Futhi izithelo, i-nitrate encane eqoqa (amahlumela aseBrussels, i-sorrel, i-peas, amazambane, ubhontshisi, anyanisi, utamatisi, amajikijolo nezithelo).
Ama-nitrate angena emzimbeni wethu hhayi kuphela ngesitshalo sokudla, kodwa nangenyama, amanzi nemithi. Ezinhlanhleni ezintsha nezinhlanzi zenyama azimbalwa. Kodwa emikhiqizweni eqedile ukulondoloza nokuthuthukisa ukunambitheka kwemithi, bonke abakhiqizi bangeza. Ama-nitrate ahlanzekile emanzini angaphansi komhlaba, ugwayi, ngisho nomzimba ngokwawo ungabakhiqiza nge-metabolism ethile.
Kulimaza kakhulu i-nitrate yomzimba womuntu kakhulu:
Umphumela wokucubungula - i-nitrites ekusebenzisaneni ne-hemoglobin ifomu le-methemoglobin, elingenakugcwalisa amaseli nge-oxygen. Ngenxa yalokho, inani le-lactic acid landa futhi amaprotheni egazini ancipha. Lokhu kuyiqiniso ikakhulu ezinganeni, izinhlelo zabo azikakwazi ukwenza ngokushesha ukuhlanganiswa kwe-methemoglobin e-hemoglobin ejwayelekile.
Banciphisa inani lamavithamini ekudleni bese kuthinta umzimba.
Ngokungeniswa okwesikhathi eside, kunesifo se-iodine nokwanda kwegciwane le-thyroid.
Kubonakala ukuthi bafaka isandla ekuthuthukiseni izicubu emaphethelweni emathunjini.
Khombisa ekubunjweni kwemvelo eyingozi emathunjini, okubuye akhiphe ubuthi futhi aphephe wonke umzimba.
Ungazivikela yini ku-nitrate noma uzivikele emiphumeleni yawo? Okokuqala, kubalulekile ukwazi ukuthi "isitha" siphi futhi uma kungenzeka ukuba siwudlulele.
Iningi lazo zonke i-nitrate esikhumbeni semifino nezithelo.
Izithelo ezingagciniwe nazo zicebile kakhulu ezitrate.
Zitholakala ngeziqu. Eduze impande. Ngakho-ke, ukusebenzisa i-celery, i-dill, njll, kungcono ukusebenzisa amaqabunga. Okufanayo kusebenza eklabishi omhlophe, empeleni ababuthelela kuwo.
Ingqungquthela yesanqante ine-nitrate engaphezulu kune-surface part.
I-nitrate enkulu emanzini omvini wevangeloni ne-melon eduze kwe-crust, engenhla eduze kwe-peduncle ye-zucchini, isitshalo seqanda, no-squash.
Emakhukhamba, isithombo, isithombo sebhitrudi ziqoqwe kuzo zombili iziphetho, ezisuswe kahle kakhulu.
Uma izithelo zingagcinwa esiqandisini, i-nitrate iyaguqulelwa kuba nitrite engozini.
Ngemuva kokugeza imifino noma izithelo kahle bese uzigcina emanzini okwesikhashana, uzonciphisa inani lemithi elimazayo ngo-20%.
Lapho upheka ama-saladi, kufanele kukhunjulwe ukuthi indawo eyingozi ikhula ngokushesha ngo-ukhilimu omuncu kanye nemayonnaise, kanye nokushintsha okuvamile okushisa. Ngakho-ke kungcono ukudla konke okulungiselelwe.
Ukwenza ama-pickle, ukulondolozwa nokukhanda, kufanele udle konke emva kwezinsuku ezingu-15, kusukela esikhathini sokuqala, kukhishwa inani elikhulu le-nitrate.
Ukusebenzisa lezi zincomo, ungavikeleka kancane endaweni elimazayo. Ungakhohlwa ukuthi umzabalazo osebenzayo ngalezi zinto ungasusa amavithamini ekudleni. Konke kufanele kutholakale ngendlela efanele futhi umphumela uzolungisa.
