Popanda izi, kukula kwabwino kwa maselo ofiira a magazi ndikosatheka, komwe kusasitsa kwamolekyulu ya DNA yomwe imanyamula zamoyo. Ndiye kuti, kukhazikitsidwa kwa chidziwitso chololera chomwe timapereka kwa ana okhala ndi majini ndizosatheka popanda gawo ili!
Ngati mutayang'ana kutanthauzira kwa ma encyclopedia, ndiye kuti mavitamini B12 amatchedwa gulu la zinthu zomwe zimakhala ndi cobalt zomwe zimatchedwa cobalamins. Nthawi zina amatchedwa cyanocobalamin, chifukwa mavitamini B12 amalowa mwanjira imeneyi thupi la munthu.
Komabe, si zokhazi! Ndinayenera kukumana ndi mawu oti B12 sichinthu china koma bakiteriya yemwe amadzipangira yekha chamoyo chilichonse, osati mtundu wina uliwonse wazinthu. Zomwe zili

Komabe, nsomba zam'madzi ndizomwe zimachokera kuzinthu izi. Zili pamwamba pa zomera ndi zobiriwira zosiyanasiyana, ngakhale pali magwero ena otsimikizira kuti palibe zomera zomwe zili nazo. Amapezekanso pang'ono mu bowa wina, monga shampignons.
Kodi nchifukwa ninji imakhala yochuluka kwambiri m’zanyama? Chifukwa chimodzi chosavuta, amapangidwa m'mimba mwa herbivores ndi kuwira kwachilengedwe kwa mabakiteriya. Zilombo, zomwe zimadya herbivore, zimapeza vitamini kuchokera ku ziwalo zake. Kuwotchera kumapezekanso m'thupi la munthu ndipo kuchuluka kwa chinthu chamtengo wapatalichi kumapangidwa, komabe, mwatsoka, izi zimachitika m'madera a m'mimba momwe kuyamwa kwa zakudya sikumakhala kokwanira.
Momwe mungathetsere kusowa kwa vitaminiKomabe, kungakhale kulakwitsa kwakukulu kunena motsimikiza kuti kuchepako kungathe kudzazidwa ndi nyama ndi mkaka!
Zakudya zamasamba zokha ziyenera kukhala ndizosankha zingapo mosiyanasiyana momwe zingathere!
Popeza munthu wathanzi amafunikira ma microkilograms 2,4 okha patsiku kuti azigwira bwino ntchito hematopoietic element, ndikokwanira kungophatikiza pazakudya zanu masamba ambiri, letesi, sipinachi ndi anyezi wobiriwira, ndi udzu wam'madzi. Masamba akhoza kuwonjezeredwa ku saladi, msuzi ndi maphunziro akulu. Zimapindulitsanso kugwiritsa ntchito chimanga cham'mawa chokhala ndi mavitamini monga chowonjezera pa zakudya zazikulu. Ngakhale sichiwonedwa ngati chinthu chachilengedwe, amathandizanso kukhala ndi mavitamini ambiri mthupi.
Zimapindulitsanso kudya zakudya zopangidwa ndi mavitamini - nthawi zambiri mkaka wokhala ndi soya wolimba, yisiti yolimbitsa thupi, mapira a chimanga, ndi zina zambiri. Kuti mudziwe ngati chakudya china chake ndi vitamini B12, onani mawu oti "cyanocobolamin" pamndandanda wazosakaniza . Zakudya zopindulitsa nazo ziyenera kusungidwa m'firiji, kutali ndi kuwala.
Pofuna kupewa, mutha kugwiritsa ntchito mavitamini kapena mavitamini otafuna m'mapapiso okhala ndi 500 mpaka 1000 μg a B12 1-2 kamodzi pamlungu. Kuwongolera zamankhwala.
