Kuyambira kale, anthu akhala akugwiritsa ntchito uchi kuti athetse matenda osiyanasiyana. M'mabungwe akale a zachipatala a Ancient Rus ali ndi maphikidwe ambiri omwe amagwiritsa ntchito uchi. Pakalipano, mankhwala a njuchi akuphunzira mokwanira, ndipo izi zimagwiritsidwa ntchito ndi anthu ambiri pofuna kupewa ndi kuchiza matenda osiyanasiyana. Komabe, wina ayenera kumvetsetsa kuti uchi ndi njira yopanda chithandizo, zomwe zimapangitsa kuti chikhalidwe cha thupi chikhale chokhazikika, ndikuchigwiritsa ntchito bwino pamodzi ndi njira zina.
Mu maonekedwe a uchi, pali pafupifupi mazana atatu zinthu, 60-80% chakudya, pafupifupi 20% madzi ndi 10-15% zina zina. Zikuluzikulu za uchi ndi fructose (33-42%) ndi shuga (30-40%). Iwo ndi ofunika kwambiri kwa anthu monga zigawo za mphamvu za chakudya ndikulowa m'magazi mosavuta popanda chiyambi cha chimbudzi ndi ziwalo za m'mimba. Shuga, zomwe timadya tsiku lililonse, zimayenera kupatulidwa kukhala shuga ndi fructose, ndiko kuti, shuga zosavuta. Choncho, kugwiritsidwa ntchito kwa uchi kumathandiza kwambiri kwa anthu omwe ali ndi vuto lopweteka kwambiri komanso omwe ali ndi shuga.
Zambiri za uchi
Shuga, yomwe ili mu uchi, ikhoza kudzaza msanga mphamvu zopanda thupi m'thupi, chifukwa chochita mwamphamvu thupi. Guluti amatha kupezeka m'magazi mkati mwa mphindi ziwiri mutatha kudya. Fructose imasonyezanso m'chiwindi ngati glycogen, yomwe imasandutsa shuga ngati pakufunika. Acetylcholine, komanso mbali ya uchi, ndi matenda a ubongo omwe amayendetsa kayendedwe ka maselo a mitsempha; Zimakhudza dongosolo lokhazikika komanso lodziwika bwino la mantha, kuthetsa nkhawa ndi mantha. Chifukwa cha fructose pachiwindi, malo osungira glycogen akukwera. Panthawi yomweyo, choline, yomwe ili mu uchi, imaletsa kunenepa kwa chiwindi. Fructose ndi shuga zimapereka mphamvu zowonjezera kuti zikhale ndi minofu ya mtima. Acetylcholine ikhoza kuthetsa ntchito ya mtima. Ngati kuchuluka kwa magazi kukupulidwa ndi mtima kumawonjezeka, kutuluka kumakhala kosavuta.
Zomwe zili ndi uchi (makamaka mu mdima), monga magnesium, cobalt, chitsulo, mkuwa ndi mavitamini a gulu B, zothandizira kupanga maselo ofiira a magazi (maselo ofiira a magazi). Komanso, chifukwa uchi uli ndi mphamvu yowonongeka komanso imakhala ndi mphamvu yaikulu ya osmotic, imatha kuteteza mabala otseguka, motero amateteza chitetezo ku matenda komanso kuthandiza kuyeretsa mabala.
Uchi ndi mankhwala othandiza kwambiri. Ma gramu mazana awiri a uchi pofuna kudya zakudya ndizofanana ndi 250 mg ya mtedza, 200 g ya mafuta a tchizi, 500 g wa beluga, 500 g wa mafuta a nsomba kapena 350 g ya ng'ombe. Lili ndi zinthu zambiri zomwe thupi lathu liyenera kuchita bwino. Thupi la munthu limatengera uchi kwathunthu (chifukwa chakuti nyama imatulutsa thupi ndi 95%, mkaka ndi 90%, mkate wa mkate ndi 85%, mbatata ndi 90%, mkate wa tirigu ndi 96%). Chilogalamu imodzi ya uchi ili ndi 3100 calories. Kwa anthu akuluakulu, chizoloŵezi cha tsiku ndi tsiku ndi 100-150 g, kwa ana 40-50 g. Mankhwala opitirira miyezo imeneyi sakuvomerezedwa, makamaka ndi kumwa kwa nthawi yaitali.
Pali maumboni ambiri onena za kugwiritsidwa ntchito kwa uchi mu chakudya cha ana m'mbuyomo (chimodzi mwa zakale kwambiri zaka za 900 BC). Kale kale ku China ankakhulupilira kuti uchi umachulukitsa mphamvu, kumalimbitsa chifuniro, kubwezeretsa ziwalo zonse zamkati, kutentha mafuta. Ku Igupto wakale, wokondedwa anapatsidwa sukulu - amakhulupirira kuti omwe amadya uchi, amakula mofulumira m'maganizo komanso mwathupi. Ku Spain, wokondedwa amakhala ngati wothandizira kuwonjezera mkaka wa m'mawere, kukhala ngati njira yothetsera thanzi la ana obadwa msanga komanso makanda, komanso ana amene amapezeka kuti ali ndi matenda a jaundice kapena anemia. Zimadziwika kuti uchi umathandiza kuwonjezeka kwa kulemera kwake kwa mwana komanso kuwonjezeka kwa hemoglobini m'magazi, kuphatikizapo kukonzanso kwa chakudya cha mwanayo komanso zotsatira zake pamtunda wa m'mimba.
