MaOxalates akanaka kuvanhu vazhinji, asi vanhu vane dambudziko rekushanda zvakanaka kwemudumbu vangada kuderedza kudya kwavo. Tsvagiridzo hairatidzi kuti maOxalates anokonzera autism kana kurwadziwa kwenguva refu kwechikadzi, asi anogona kuwedzera njodzi yematombo eitsvo mune vamwe vanhu.
Oxalic acid chinhu chinowanikwa mumiti yakawanda, kusanganisira miriwo, miriwo, michero, koko, nzungu, nembeu (1).
Muzvirimwa, inowanzo sanganiswa nemaminerari kuti igadzire maoxalate. Mazwi ekuti "oxalic acid" uye "oxalate" anoshandiswa zvakafanana mune zvesainzi yezvekudya.
Muviri wako unogona kugadzira maoxalate wega kana kuawana kubva muchikafu. Vhitamini C inogonawo kushandurwa kuita maoxalate kuburikidza nemetabolism (2).
Kana ikadyiwa, maoxalate anogona kusangana nemaminerari kugadzira makemikari anosanganisira calcium oxalate ne iron oxalate. Anonyanya kuitika muura, asi anogonawo kuitika muitsvo nedzimwe nzvimbo dzeweti.
Zvisinei, kune vanhu vane hanya nepfungwa, kudya zvine maoxalates akawanda kunogona kuwedzera njodzi yematombo eitsvo nezvimwe zvinetso zvehutano.
Oxalate iasidhi yeorganic inowanikwa mumiti, asi inogonawo kugadzirwa nemuviri. Inobatanidza zvicherwa uye inobatanidzwa nekuumbwa kwematombo eitsvo nezvimwe zvinetso zvehutano.
Chimwe chezvinhu zvinonyanya kukonzera matambudziko ehutano ane chekuita neoxalates ndechekuti anogona kusungira zvicherwa muura uye kudzivirira kuti zvisanyungudike nemuviri.
Semuenzaniso, sipinachi ine calcium yakawanda uye oxalates, izvo zvinodzivirira muviri kuti usatore calcium yakawanda (4).
Zvisinei, zvakakosha kuyeuka kuti mamwe maminera ari muzvikafu chete anosunga kune maoxalates.
Kunyange zvazvo kutorwa kwecalcium kubva muspinachi kuchidzikira, kudya mukaka nesipinachi pamwe chete hakukanganisi kutorwa kwecalcium kubva mumukaka (4).
Maoxalates anogona kusunganidza zvicherwa muura uye kukanganisa kunyudzwa kwemamwe acho, kunyanya kana akabatanidzwa nefayibha.
Kazhinji, calcium neoxalate shoma zvinowanikwa pamwe chete muweti, asi zvinoramba zvakanyunguduka uye hazvikonzeri matambudziko.
Zvisinei, dzimwe nguva anobatana kuti aumbe makristaro. Mune vamwe vanhu, makristaro aya anogona kukonzera kuumbwa kwematombo, kunyanya kana huwandu hweoxalate hwakakwira uye weti inobuda yakaderera (1).
Matombo madiki haawanzo kukonzera matambudziko, asi matombo makuru anogona kukonzera kurwadziwa kwakanyanya, kuda kurutsa, uye ropa muweti paanenge achipfuura nemuurethra.
Saka, vanhu vane nhoroondo yematombo eitsvo vanogona kukurudzirwa kuderedza kudya kwavo chikafu chine maoxalates akawanda (7, 8).
Zvisinei, kurambidzwa kwe oxalate zvachose hakuchakurudzirwi kune varwere vese vane matombo eitsvo. Izvi zvinodaro nekuti hafu ye oxalate inowanikwa muweti inogadzirwa nemuviri pane kutorwa kubva muchikafu (8, 9).
Vanachiremba vazhinji vezvedundira vava kupa vanhu chikafu chine oxalate shoma (chisingasviki 100 mg pazuva) chete kune varwere vane weti ine oxalate yakawanda (10, 11).
Saka, zvakakosha kuti nguva nenguva uongorore kuti zvinodikanwa kudzikamisa zvinhu zvakadii.
Zvikafu zvine maoxalate akawanda zvinogona kuwedzera njodzi yematombo eitsvo kuvanhu vane chirwere ichi. Zvinokurudzirwa kuti vanhu vaderedze kudya maoxalate zvinoenderana nehuwandu hwemaoxalate muweti.
Vamwe vanoti maoxalates anogona kunge aine chekuita ne vulvodynia, iyo inoratidzwa nekurwadziwa kwenguva refu, kusingatsananguriki kwechikadzi.
Zvichibva pamhedzisiro yechidzidzo, vaongorori vanotenda kuti mamiriro ese ari maviri haagone kukonzerwa ne dietary oxalates (12, 13, 14).
Zvisinei, muchidzidzo chakaitwa muna 1997 apo vakadzi makumi mashanu nevapfumbamwe vaiva nevulvodynia vakarapwa nekudya kusina oxalate yakawanda uye calcium supplements, vanenge chikamu chimwe muzvina vakaona kuvandudzika kwezviratidzo (14).
Vanyori vekudzidza vakagumisa kuti maoxalates ekudya anogona kuwedzera pane kukonzera chirwere ichi.
Dzimwe nyaya dzepaindaneti dzinobatanidza maoxalates ne autism kana vulvodynia, asi zvidzidzo zvishoma zvakaongorora kubatana kungangoitika. Tsvagiridzo yakawanda inodiwa.
Vamwe vanhu vanotenda kuti kudya chikafu chine maoxalates akawanda kunogona kukonzera autism kana vulvodynia, asi tsvakiridzo yazvino haitsigire zvirevo izvi.
Vamwe vanotsigira kudya kwe low-oxalate vanoti zvakanakira kuti vanhu vasadye chikafu chine maoxalate akawanda nekuti chinogona kukanganisa hutano.
Zvisinei, zvese hazvisi nyore. Zvizhinji zvezvikafu izvi zvine hutano uye zvine ma antioxidants akakosha, fiber, nezvimwe zvinovaka muviri.
Zvikafu zvakawanda zvine maoxalates zvinonaka uye zvine hutano. Kune vanhu vazhinji, kuzvidzivisa hazvina basa uye zvinogona kutokuvadza.
Mamwe maoxalate aunodya anopwanywa nemabhakitiriya ari mudumbu mako asati asanganiswa nemaminerari.
Rimwe remabhakitiriya aya, Oxalobacterium oxytogenes, rinotoshandisa oxalate senzvimbo yesimba. Izvi zvinoderedza zvakanyanya huwandu hweoxalate inotorwa nemuviri (15).
Zvisinei, vamwe vanhu havana mabhakitiriya aya akawanda mudumbu ravo nekuti mishonga inorwisa mabhakitiriya inoderedza huwandu hwemakoroni eO. formigenes (16).
Pamusoro pezvo, zvidzidzo zvakaratidza kuti vanhu vane chirwere chemudumbu chinozvimba vane mukana wakawedzerwa wekuva nematombo muitsvo (17, 18).
Saizvozvowo, huwandu hwakawanda hweoxalate hwakawanikwa muweti yevanhu vakambovhiyiwa gastric bypass kana mamwe maitiro anochinja mashandiro emudumbu (19).
Izvi zvinoratidza kuti vanhu vanotora mishonga inorwisa mabhakitiriya kana kuti vane dambudziko rematumbu vanogona kubatsirwa zvakanyanya nekudya zvine oxalate shoma.
Vanhu vazhinji vane hutano hwakanaka vanogona kudya chikafu chine maoxalates akawanda pasina matambudziko, asi vanhu vane mashandiro emudumbu akachinja vangangoda kuderedza kudya kwavo.
Maoxalates anowanikwa mumiti inenge yese, asi mamwe ane huwandu hwakawanda uye mamwe ane huwandu hushoma (20).
Saizi dzezvikafu zvinogona kusiyana, zvichireva kuti zvimwe zvekudya zvine "oxalate yakawanda", zvakaita sechicory, zvinogona kunzi low oxalate kana saizi yekudya iri diki zvakakwana. Heino runyorwa rwezvikafu zvine maoxalate akawanda (anopfuura 50 mg pa 100-gram serving) (21, 22, 23, 24, 25):
Huwandu hweoxalate mumiti hunotangira pakakwirira kusvika pakaderera zvikuru. Zvekudya zvine maoxalate anopfuura 50 milligrams pachikamu chimwe nechimwe zvinoiswa muchikamu che "high oxalate."
Vanhu vanodya chikafu chine oxalate shoma nekuda kwematombo eitsvo vanowanzo kumbirwa kudya mamirigiramu asingasviki makumi mashanu eoxalate pazuva.
Kudya kwakaringana uye kunovaka muviri kunogona kuwanikwa kana uine oxalate iri pasi pe50 mg pazuva. Calcium inobatsirawo kuderedza kunyudzwa kweoxalates.
Zvisinei, vanhu vane hutano hwakanaka vanoda kugara vaine hutano havafanirwe kudzivirira kudya zvine zvinovaka muviri nekuti vane maoxalates akawanda.
Nyanzvi dzedu dzinogara dzichiongorora hutano uye hutano uye dzichivandudza zvinyorwa zvedu sezvo ruzivo rutsva ruchiwanikwa.
