Okwangoku, inani elikhulu labantu abanakho ukungena kwe-acid eliclic acid, kodwa kwiimeko ezininzi abakwaziyo ngoku. Kodwa i-aclic acid (okanye, ngenye indlela, i-vitamin B9) yinto ebaluleke kakhulu kumzimba, kubaluleke kakhulu kwi-vitamin. Ingakumbi ibonisa ukungabikho kwale vithamini kubantwana nakwabasetyhini ngexesha lokukhulelwa.
Ukungabikho kwe-vitamin B9 kudla ngokukhawuleza. Nangona kunjalo, emva kwexesha, umntu uyacaphuka, ukhathala kwanda kunye nesondlo siyancipha, ke ukuhlanza, isifo sohudo sinokuvela, kwaye ekugqibeleni inwele iphuma, kunye nefom yefom yomlomo. I-acid ye-folic inxaxheba kwiinkqubo ezininzi ezenzeka emzimbeni: ukwakheka kwe-erythrocytes, ukusebenza kweenqwelo zomzimba, iintsholongwane kunye neemzimba zokuzivikela, izicwangciso zesisombululo, umsebenzi wegciwane lesisu. Xa kunqongophala kakhulu kwe-aclic folic, i-megaloblastic anemia ikhula, ngezinye izihlandlo iholela ekufeni.
I-Vitamin B9 ichitheka emanzini, umzimba womntu awuhlanganiswa, ufike ngokutya, kwaye unokuveliswa ngama-microorganisms emathunjini amakhulu.
Imisebenzi yeVithamini B9
Iipropati ze-folic acid zininzi, ngoko kubalulekile:
- uthatha inxaxheba kwi-assimilation, ezothutho kunye nokubola kweeprotheni;
- kuphucula ukusebenza komzimba kunye nengqondo;
- uthatha inxaxheba kwiinkqubo zokuxilonga;
- luyimfuneko kwi-synthesis ye-RNA ne-DNA, ejongene nokugcinwa kunye nokuhanjiswa kweempawu zobomi;
- khuthaza ukufana kwe-amino acids kunye noshukela;
- inqanda ukubunjwa kwezidumbu;
- unempembelelo yomzimba;
- ithatha inxaxheba kwinkqubo yokwakhiwa kweeseli zegazi (i-leukocyte, i-erythrocytes kunye neeplatelets);
- inqanda ukuphuhliswa kwe-atherosclerosis;
- Ukukhawuleza ukuvuselela (ukuphilisa) iinkqubo;
- ubeka umgangatho womsebenzi wegama lokutya;
- igalelo ekwandiseni kwimveliso yobisi.
Ngethuba lokukhulelwa, ukuba ne-vitamine ibalulekile kubaluleke kakhulu, ekubeni i-vitamin B9 ayibandakanyeki kuphela ekuvelweni nasekuphuhlisweni kwebhanki ye-neural ye-fetus, kodwa igalelo ekusebenzeni ngokuqhelekileyo kwe-placenta.
Ukutya okuqukethe i-folic acid
I-acid ye-folic inokufumaneka kwiindawo ezahlukeneyo zokutya: ezi zinto ziyimveliso yesibini kunye nesilwanyana.
Iyokuqala: imifuno eluhlaza (i-lettuce, i-parsley, i-anyanisi eluhlaza, isipinashi), iimbotyi (iifisi ezihlaza, iimbotyi), ezinye iinkozo (i-oat kunye ne-buckwheat), i-bran, ibhanana, iinqotyi, i-ithin, imvubelo, amantongomane, i-apricots, i-oranges, amakhowe .
Kuluhlu lwemveliso yemvelaphi yezilwanyana: inkukhu, isibindi, intlanzi (i-salmon, ityhuna), imvana, ubisi, inyama, inyama, amaqanda.
Ukungabi ne-acid ye-folic ngexesha lokukhulelwa
Ngexesha lokukhulelwa, ukungabikho kwe-vitamin B9 kunokukhokelela kwimiphumo engapheliyo:
- i-cerebral hernia;
- ukukhulelwa kwesisu sokukhulelwa;
- i-palate yengxolo okanye umlomo we-hare;
- ukuhanjiswa kwangethuba;
- i-edema yengqondo (i-hydrocephalus);
- ukuphazamiseka kwamaplanga;
- ukulibaziseka ekuphuculweni kwengqondo komntwana;
- spina bifida kumntwana;
- ukubeletha nokukhupha isisu;
- ukungabikho kwengqondo (unencephaly);
Kwimeko yokuntula kakhulu ukukhulelwa kungaboniswa kwifomu:
- Toxicosis;
- intlungu emilenzeni;
- ukuxinezeleka.
Imfuno ye-folic acid ngosuku
Umntu omdala wemihla ngemihla u-400 mcg. Kwabesetyhini abakhulelweyo, imfuno iphindwe kabini ngaphezulu - 800 mcg.
Ukongezelela, ukungenisa iivithamini kufuneka kuqalwe kwimeko:
- isidingo sokwanda kwexesha le-aclic acid (ixesha lokulahlwa, ukukhulelwa, iminyaka yabantwana (ixesha lokukhula), ukuthatha i-contraceptive, abantu abanomdlavuza);
- ukubonelela ngokwaneleyo kwezinto ezinokutya;
- ukuphazamiseka kwenkqubo yokumangcwaba emathunjini.
Iimviwo zokuthatha i-vitamin B9 kwabasetyhini abakhulelweyo
Inketho efanelekileyo yimeko xa umfazi eqala ukuthatha i-vitamin kwiinyanga ezintathu ngaphambi kokuqala kokukhulelwa. I-acid ye-folic ekhulelwe imiselwe ngexesha lokubeka kunye nokwakhiwa kwebheysi ye-neural ye-fetus, oko kukuthi, kwiiveki zokuqala ezi-12-14. Ukufunyanwa ngokuthintela kunciphisa amathuba okuphuhlisa iziphene ze-neural kunye nokubonakala kweengxaki ezahlukeneyo.
