Ekusebenzeni kwezilwane, i-avitaminosis yikuntuleka emzimbeni wenyoni ethile yevithamini ethile.
Ngamanye amakhemikhali asebenzayo aphethwe yizinqubo ezithile zomzimba ezinkukhu.
Inyama yezinkukhu ikakhulukazi engazi ukuthi ikhona i-vitamin A.
Ngokuphathelene nalokhu kutholakala kwamavithamini sizoxoxa kule ngxenye bese sizama ukuthola indlela yokuvimbela imiphumela emibi.
Kuyini i-beriberi Futhi ezinkukhu?
I-Avitaminosis A ibonakala uma kungenakho ukuphela noma ukuntuleka okucacile kwe-vitamin A ekudleni. Iqiniso ukuthi le vithamini ewusizo idlala indima ebaluleke kakhulu emzimbeni wenkukhu. Uhileleke ngokugcwele kuzo zonke izinqubo zokuqubuzana ezivela ezingxenyeni zangaphakathi zomuntu ngamunye.
Ngaphezu kwalokho, i-vitamin A noma i-carotene iyadingeka kuzo zonke izinqubo zokukhula. Ngaphandle kwalo, akukho inkukhu ingaba yinyoni enkulu enkulu futhi eqinile. Isiza amathambo ukuba aqine futhi asebenze isikhathi eside, futhi imisipha ngosizo lwayo ibe namandla futhi aqinile.
I-Carotene nayo inegalelo ekusebenzeni okuvamile kwesimiso somzimba sokuzivikela. Uma inkukhu ithola ukuhlushwa okudingekile kwalesi sifo, kungcono ukubekezelela izifo ezithathelwanayo ezithinta isifo esithathelwanayo futhi ziphikisana kakhulu nezifo ezintsha ezikhona.
Isigaba sengozi
Abahlengikazi bezilwane zakudala abathole bafunde ngendima yamavithamini emzimbeni wenkukhu, yingakho irekhodi le-vitamin A labonakala lisaba khona.
Manje ochwepheshe bangasho ngokuqinisekile ukuthi yiziphi izinqubo ze-carotene ezithintekayo.
Ngeshwa, i-avitaminosis A, njengenye i-avitaminosis, ayibonakali ngokushesha, ngakho-ke ngisho nomlimi owaziwayo ekuqaleni akukwazi ukusho ukuthi umhlambi wakhe ubhekene nokuntuleka kwamavithamini noma kulungile.
Ama-vets athola lokho ukuntuleka kwevithamini A kuyabonakala ngokushesha, kodwa emva kwezinyanga ezimbalwa zokudla okungalungile.
Izinyoni kufanele zithole ukudla okwanele sonke lesi sikhathi ukuze umzimba wazo uzizwe ukungabi nalesi sakhi esiwusizo samakhemikhali.
Kodwa-ke, iqiniso lokuthi izinkukhu azipheli neze ngokusweleka kwevithamini A ngeke zihluleke ukujabulisa noma yimuphi umfuyi. Izinkukhu eziningi kakhulu zifa ezifweni ezihlukahlukene ezithathelwanayo eziyingozi.
I-Avitaminosis A kumele yenzeke ngesimo esibi kakhulu ukuze inyoni izofa. Yingakho umlimi enethuba lokuphulukisa yonke imfuyo ngaphambi kokuphuza. Lokhu kunikeza isikhathi esengeziwe futhi kunciphisa ukulimala okungenzeka.
Izizathu
I-Avitaminosis A ikhula emzimbeni wenkukhu ngenxa yokungabi nalutho kwaleli vithamini noma, njengoba kuthiwa, i-carotene.
Ngokujwayelekile, imbangela yezinguquko ekusetshenzisweni kwemithi, lapho i-vitamin A ehilelekile, isondlo esingalungile senyoni. Ngokuvamile kuqukethe inani elincishisiwe laleli khemikhali.
Izinkukhu ikakhulukazi ziqala ukuzwa ukuntuleka kwe-carotene ngenkathi yasebusika, lapho izakhi ezintsha zingenakutholwa kwondlo. Ebusika, abalimi bazama ukuncelisa izinyoni ngesondlo esomile, njengoba ifolda eluhlaza iba yabiza kakhulu.
Enye imbangela yokuntuleka kwevithamini A kungaba noma yisiphi isifo esithathelwanayo esingathí sina. Kanciphisa kancane umzimba wonke wenkukhu, ngakho-ke uzama ukusebenzisa i-carotene engaphezulu. Ezimweni ezinjalo, inkukhu ayikwazi ukuthola inani elifanele lamavithamini, ngakho ngokushesha liqala ukuhlushwa yi-vitamin.
Isimo esingokwemvelo esifundeni lapho ipulazi ikhona khona singabizwa ngokuthi yisici esibalulekile esithinta ukuthuthukiswa kwe-beriberi. Ezindaweni ezinomoya ohlanzekile nenhlabathi, izinkukhu zincane kakhulu ukuthi zihlushwa izifo ezinjalo.
Izifundo nezimpawu
Cishe njalo, ukutholakala kwevithamini A kwenzeka ezithombeni ezincane. Izinkukhu ziqala ukuhlupheka ngenxa yalesi sifo ngemuva kwesonto noma izinyanga ezimbalwa.
Umuntu ngamunye uphendula ngendlela yakhe ekuntulekeni kwaleli vithamini, ngakho-ke kunzima ukusungula izinsuku eziqondile.
Ezilwaneni ezincane, kukhona ukuhambelana komhlaba jikelele ukusebenzisana. Abakwazi ngisho nokuma futhi bahambe, futhi lapho behamba, imilenze yabo iyanuka. Ngesikhathi esifanayo i-conjunctiva iqala ukuvutha, okuyinto esikhathini esizayo engase iholele ekumpumpheni kwenyoni.
Futhi, ukuntuleka kwe-vitamin A kuyathinta kakhulu ukusebenza kwesimiso sezinzwa. Izimpawu ezesabekayo zivela ezinkukhu ezincane, ukunyakaza kwazo kuyaqina, izinyoni ezinjalo zivame ukuzamazama.
Kwezinye izimo, uketshezi olucacile luqala ukugeleza kusuka ekhaleni labo, okuyinto ngokuvumelana kwalo kufana ne-snot.
Ezimweni eziphambili kakhulu ze-avitaminosis A, le nyoni inayo ukuphela kokulahlekelwa kwesisindo somzimbaokuthiwa i-dystrophy. Inkukhu iba buthakathaka, ayikwazi ukujikeleza egcekeni. Unenkinga yokudla okunomsoco, ngezinye izikhathi wenqaba ngokuphelele ukudla kanye namanzi, okuholela ngokushesha ekukhatheni.
Izinkukhu Umbala omhlophe wesikhumba seqhwa uzohlobisa noma iyiphi i-monasteri!Ngemva kokufunda lesi sihloko //selo.guru/ptitsa/kury/bolezni/narushenie-pitaniya/avitaminoz-rr.html, uzofunda ukuthi i-beriberi RR eyingozi ezinkukhu.
Ngeshwa, ababelethi bezinyoni abaqapheli kakhulu ukuphazamiseka ekuqaleni, ngoba izinkukhu zihlale zigcwele amaphuphu amaningi. Iqala ukuwela kuphela ezimweni ezinzima kunazo zonke ze-avitaminosis A.
Ukuhlonza
Ukuzimisela ukuxilongwa okuqondile izilwane zezilwane zihlola isibindi se-vitamin A ngokuningiliziwe. Ku-1 g yesibindi somkhuhlane omdala onempilo kufanele kube ngu-300 kuya ku-500 μg ka-vitamin A, ezinkukhu ezinsuku ezineminyaka engu-30, emini ezincane ezineminyaka engu-10, 30, 60-120 izinsuku 40-60 μg, 100-150 μg, 200-300 μg ngokulandelana.
Isibonakaliso sokuqala kokwelashwa yisilungiselelo ku-5 amagremu esibindi nge-5.9 μg ye-carotene. Futhi, abanye abantu bangabhalisa ukungabi naso okuphelele kwevithamini A, okudinga ukwelashwa okusheshayo futhi okuphakeme kakhulu kwezokwelapha.
Ukwelapha
Ukwelashwa kwanoma yikuphi ukutholakala kwamavithamini kulula.
Kwanele ukulungisa ngokuphelele ukudla kwezinkukhu, ukuze bathole inani elidingekile levithamini elingekho.
Ngomuthi omkhulu we-carotene, emzimbeni wenyoni ngenxa yokuphendula kwamakhemikhali iba i-vitamin A, iqukethe isanqante, izitshalo ezincane eziluhlaza kanye nofulawa obusatshani.
Zonke izithako ezifakwe ohlwini zingahle zichotshozwe futhi zengezwe ukuphakela izinkukhu. Lokhu kuzokwenza ukuthi ukudla kwezinkukhu kuphelele kakhulu futhi bayothola masinyane, babuyiselwe emuva kwe-avitaminosis A.
Ukuvimbela
Ukuvimbela okuphumelelayo kakhulu kwe-beriberi kubhekwa ukudla okuphelele nokulinganisela.
Ukuze ukondle izinyoni epulazini lezinkukhu, kuphela ukudla okunjalo okufanele kukhethwe, okuqukethe ekubunjweni kwawo lonke uhla lwezinto eziwusizo. Ngesikhathi esifanayo, zonke izakhi kumele zibe nesilinganiso ukuze kungabikho ngaphezulu kokushukela okwenzeka emzimbeni wenkukhu.
Ukuze uthole ukudla ebusika, ungasebenzisa ukudla okukhethekile okuqinisekisiwe, okugcwalisa kahle ukungabi nalutho kokudla okuluhlaza. Ngezinye izikhathi ungasebenzisa izithako esikhundleni salokhu okuphakelayo. Zisemhlabathini futhi zongezwe kunoma yikuphi ukuphakela kwezinkukhu.
Uma inyoni ethile isesimweni esibuthakathaka, ingabe inganikwa i-vitamin A ngokwehlukana ngendlela yamafutha wezinhlanzi, amaphilisi noma imijovo, kuye ngesimo sayo.
Isiphetho
I-Avitaminosis A akuyona isifo esingenabungozi, njengoba singase sibonakale ekuqaleni. Iba nemiphumela eminingi engathinti isimo esijwayelekile senyoni.
Esimweni sokunganakwa, lolu hlobo lwe-avitaminosis lungabangela ukufa kwenkukhu noma kuyenciphisa kakhulu kangangokuthi kuzozibulala ngaphandle kokungenisa ukudla.
