Ndikudabwa chifukwa chiyani timachita mantha ndi mawu akuti "nitrates"? Mu sayansi, izi ndizitsulo zopanda phindu za nitric acid, zomwe zomera zimadya kuchokera ku nthaka monga chinthu chofunikira kwambiri. Zamasamba popanda nitrates ndi zochita zawo pa thupi la munthu sizingowoneka. Chiwerengero chiwerengero! Ngati mankhwalawa amalowa kwambiri mmunda (chifukwa cha feteleza yogwiritsa ntchito nthaka ndi nitrate), amangoziika pamtengo! Komabe, chowopsa chachikulu cha poizoni ndi oyambirira masamba si azitrates okha, koma nitrites anapangidwa kuchokera iwo mu thupi. Kulowa mwazi, kungachititse kuti mpweya wa mpweya ukhale ndi njala, kusokoneza ntchito ya m'mimba, kuwonjezera pa oncorrhiza, komanso kugwiritsa ntchito mlingo waukulu wa nitrates kumayambitsa poizoni. N'zoona kuti mavutowa ndi ovuta kudya zakudya za nitrate. Komabe, popeza kuti ndizosatheka kudziwa kuchuluka kwa "madzi" mu masamba kapena chipatso ndi diso, kusamala sikungalepheretse.
Mwa njira, chikhalidwe chovomerezeka cha tsiku ndi tsiku cha nitrates, malinga ndi bungwe la WHO, ndi 3.7 mg pa 1 makilogalamu a kulemera kwa thupi.
Zomera zimasiyana ndi zomwe zimatha kuunjikira nitrates ndi zotsatira zake pa thupi la munthu: zizindikiro zapamwamba (mpaka 3000 mg) - masamba a masamba, beets, radishes ndi mavwende; Pakatikati (400-900 mg) - zukini, dzungu, kabichi, kaloti, nkhaka; / otsika (50-100 mg) - nyemba, sorelo, mbatata, anyezi, tomato, zipatso ndi zipatso.
Zolemba zonse zomwe zili mu nitrates (80% pamwamba pa chikhalidwe!) - oyambirira radish. Izi zimachokera ku katundu wake kuti atenge chinyezi padziko lapansi (pamodzi ndi nitrates).
Kawirikawiri masamba okwera kutentha amawonongedwa ndi masamba otentha.
Sankhani zipatso zakukhwima ndikuzisungira m'firiji (kutentha, kutentha kwa zakudya m'thupi). Mwa njirayi, saladi zopangidwa kuchokera ku masamba oyambirira, ndi zofunika kuti musagwiritse ntchito mankhwalawa - iwo amayambitsa mchere wa nitric asidi.
Ntchito zapakhomo
Mwamwayi, pali njira zambiri zochepetsera chiwopsezo cha masamba oyambirira popanda kusiya kakhitchini yanu! Choyamba, tifunika kuchotsa masamba awiri kapena atatu komanso chitsa - pamenepo, monga lamulo, zimapangidwira. Kenaka yambani chipatsocho bwinobwino ndi burashi (soda soda: supuni imodzi pa lita imodzi yamadzi, nutsuka mwachizolowezi). Ndipo muyeretsedwe bwino: kaloti ndi nkhaka - kudula kumbali zonse ziwiri ndi masentimita 1, kudula radishes kuchokera ku radishes ndi tomato. Mu maluwa ndi letesi ayenera kudya masamba okha, osati zimayambira (iwo amaunjikira nitrates). Mukhozanso kuthirira masamba musanagwiritse ntchito kwa theka la ora. Izi zidzachotsa 25-50% nitrate. Ngati kuphika kwina kukutsatila, kumapanga 25-50% ya "chemistry". Njira yopindulitsa kwambiri - kuphika: ikani masamba osungunuka m'madzi popanda mchere (mchere - kumapeto kwa kuphika), kuphika, ndiye kukhetsa msuzi. Mwa njira, pamene mwachangu, nitrates amamasuliridwa opanda vuto mopanda phindu - pokhapo 10 peresenti. Koma chowawa, ndithudi, chovomerezeka: mu kabichi okonzedwa motere, kale pa tsiku lachisanu mlingo wa nitrates wafupika ndi theka.
Inde, palinso zosokoneza ndi njirayi - kuchuluka kwa mavitamini, ntchentche, imachepetsanso kwambiri. Ndiyenera kuchita chiyani? Pali zinthu zingapo zomwe mungachite: mungachedwe kugula "achinyamata ndi oyambirira" (mu nthaka zipatso ndi nitrates nthawi zambiri). Mukhoza kukula ndi eco mankhwala (saladi, anyezi, masamba okometsera) kunyumba pakhomo, kapena kuchepetsa vitamini kutaya ndi tiyi wobiriwira kapena zakumwa zakumwa. .. Kusankha ndi kwanu!
Osati kwambiri nitrate ...
Asayansi ena amaganiza kuti nitrates mu mlingo woyenera ndi othandiza kwa thupi lathu! Kawirikawiri munthu amadzipangira yekha mpaka 25-50% mwa mankhwalawa, ena onse amapezeka ndi chakudya. Ndipo izo ziri mu zakudya zamtundu, madzi, mowa. Kale m'kamwa mwachitsulo mothandizidwa ndi mabakiteriya nitrates amasandulika nitrites, ndi mpeni kulowa mmimba. Malingana ndi kafukufuku wa ofufuza a ku Sweden, pali opangidwa ndi nitrosamines ambiri, omwe ndi othandiza kwa nitrogen oxide ya munthu (yomwe imathandiza kuyendetsa magazi m'mimba, kutetezera ku gastritis, zilonda ndi zotsatira za mankhwala osokoneza bongo).
