Ma oxalate ndi abwino kwa anthu ambiri, koma anthu omwe ali ndi vuto la matumbo osokonekera angafune kuchepetsa kudya. Kafukufuku sakusonyeza kuti ma oxalate amayambitsa autism kapena kupweteka kosatha kwa m'mimba, koma amatha kuwonjezera chiopsezo cha miyala ya impso mwa anthu ena.
Oxalic acid ndi mankhwala achilengedwe omwe amapezeka m'zomera zambiri, kuphatikizapo masamba obiriwira, ndiwo zamasamba, zipatso, koko, mtedza, ndi mbewu (1).
Mu zomera, nthawi zambiri zimasakanikirana ndi mchere kuti zipange ma oxalate. Mawu akuti "oxalic acid" ndi "oxalate" amagwiritsidwa ntchito mofanana mu sayansi ya zakudya.
Thupi lanu limatha kupanga ma oxalate lokha kapena kuwapeza kuchokera ku chakudya. Vitamini C imathanso kusinthidwa kukhala ma oxalate kudzera mu kagayidwe kachakudya (2).
Akameza, ma oxalate amatha kusakanikirana ndi mchere kuti apange zinthu monga calcium oxalate ndi iron oxalate. Amapezeka makamaka m'matumbo, komanso amatha kupezekanso mu impso ndi ziwalo zina za mkodzo.
Komabe, kwa anthu omwe ali ndi vuto la khungu, kudya zakudya zokhala ndi ma oxalates ambiri kungapangitse kuti pakhale matenda a impso komanso mavuto ena azaumoyo.
Oxalate ndi asidi wachilengedwe womwe umapezeka m'zomera, koma thupi limathanso kupanga. Amalumikizana ndi mchere ndipo amalumikizidwa ndi kupangika kwa miyala ya impso ndi mavuto ena azaumoyo.
Chimodzi mwa zinthu zomwe zimayambitsa mavuto azaumoyo ndi ma oxalates ndikuti amatha kumangirira ku mchere m'matumbo ndikuletsa kuti asatengeke ndi thupi.
Mwachitsanzo, sipinachi ili ndi calcium ndi oxalates zambiri, zomwe zimalepheretsa thupi kuyamwa calcium yambiri (4).
Komabe, ndikofunikira kukumbukira kuti michere ina yokha yomwe ili muzakudya imagwirizana ndi ma oxalates.
Ngakhale kuyamwa kwa calcium kuchokera ku sipinachi kumachepa, kudya mkaka ndi sipinachi pamodzi sikukhudza kuyamwa kwa calcium kuchokera ku mkaka (4).
Ma oxalates amatha kumangirira ku mchere m'matumbo ndikusokoneza kuyamwa kwa ena mwa iwo, makamaka akaphatikizidwa ndi ulusi.
Kawirikawiri, calcium ndi oxalate pang'ono zimapezeka pamodzi mu mkodzo, koma zimakhalabe zosungunuka ndipo sizimayambitsa mavuto aliwonse.
Komabe, nthawi zina amaphatikizana kupanga makhiristo. Mwa anthu ena, makhiristo amenewa angayambitse kupanga miyala, makamaka ngati kuchuluka kwa oxalate kuli kokwera ndipo mkodzo umatulutsa pang'ono (1).
Miyala yaying'ono nthawi zambiri siimayambitsa mavuto, koma miyala ikuluikulu ingayambitse kupweteka kwambiri, nseru, ndi magazi mu mkodzo pamene ikudutsa mu mkodzo.
Chifukwa chake, anthu omwe ali ndi mbiri ya miyala ya impso angalangizidwe kuchepetsa kudya zakudya zokhala ndi ma oxalates ambiri (7, 8).
Komabe, kuchepetsa kwathunthu kwa oxalate sikuvomerezedwanso kwa odwala onse omwe ali ndi miyala ya impso. Izi zili choncho chifukwa theka la oxalate yomwe imapezeka mu mkodzo imapangidwa ndi thupi m'malo motengedwa kuchokera ku chakudya (8, 9).
Akatswiri ambiri a urology tsopano amalangiza odwala omwe ali ndi oxalate yambiri mkodzo kuti azidya zakudya zochepa (zosakwana 100 mg patsiku) okhawo omwe ali ndi oxalate yambiri mkodzo (10, 11).
Chifukwa chake, ndikofunikira kuyesa nthawi ndi nthawi kuti mudziwe kuchuluka kwa zoletsa zomwe zikufunika.
Zakudya zokhala ndi ma oxalate ambiri zingawonjezere chiopsezo cha miyala ya impso mwa anthu omwe ali pachiwopsezo chachikulu. Malangizo ochepetsera kudya ma oxalate amadalira kuchuluka kwa ma oxalate mu mkodzo.
Ena amanena kuti ma oxalates amatha kugwirizanitsidwa ndi vulvodynia, yomwe imadziwika ndi ululu wosatha komanso wosamvetsetseka wa m'mimba.
Kutengera ndi zotsatira za kafukufukuyu, ofufuza amakhulupirira kuti matenda onsewa sangachitike chifukwa cha ma oxalates a zakudya (12, 13, 14).
Komabe, mu kafukufuku wa 1997 pomwe amayi 59 omwe anali ndi vulvodynia adathandizidwa ndi zakudya zochepa za oxalate ndi zowonjezera calcium, pafupifupi kotala adawona kusintha kwa zizindikiro (14).
Olemba kafukufukuyu adatsimikiza kuti ma oxalates azakudya amatha kukulirakulira m'malo moyambitsa matendawa.
Nkhani zina za pa intaneti zimagwirizanitsa ma oxalates ndi autism kapena vulvodynia, koma kafukufuku wochepa ndi amene wafufuza kugwirizana komwe kungatheke. Kafukufuku wowonjezera akufunika.
Anthu ena amakhulupirira kuti kudya zakudya zokhala ndi ma oxalates ambiri kungayambitse autism kapena vulvodynia, koma kafukufuku waposachedwapa sakugwirizana ndi zomwe akunenazi.
Anthu ena okonda zakudya zokhala ndi oxalate yochepa amati ndi bwino kuti anthu asamadye zakudya zokhala ndi oxalate yambiri chifukwa zimatha kuwononga thanzi lawo.
Komabe, zonse sizophweka. Zakudya zambirizi ndi zathanzi ndipo zili ndi ma antioxidants, ulusi, ndi michere ina yofunika.
Zakudya zambiri zokhala ndi ma oxalates ndi zokoma komanso zopatsa thanzi. Kwa anthu ambiri, kupewa zakudya zimenezi sikofunikira ndipo kungakhale kovulaza.
Zina mwa ma oxalate omwe mumadya zimasweka ndi mabakiteriya m'matumbo mwanu musanaphatikizidwe ndi mchere.
Chimodzi mwa mabakiteriya amenewa, Oxalobacterium oxytogenes, chimagwiritsa ntchito oxalate ngati gwero la mphamvu. Izi zimachepetsa kwambiri kuchuluka kwa oxalate komwe thupi limayamwa (15).
Komabe, anthu ena alibe mabakiteriya ambiri m'matumbo mwawo chifukwa maantibayotiki amachepetsa chiwerengero cha ma colonies a O. formigenes (16).
Kuphatikiza apo, kafukufuku wasonyeza kuti anthu omwe ali ndi matenda otupa m'matumbo ali ndi chiopsezo chowonjezeka cha matenda a impso (17, 18).
Momwemonso, kuchuluka kwa oxalate kwapezeka mu mkodzo wa anthu omwe adachita opaleshoni ya m'mimba kapena njira zina zomwe zimasinthasintha magwiridwe antchito a matumbo (19).
Izi zikusonyeza kuti anthu omwe akumwa maantibayotiki kapena omwe ali ndi vuto la m'mimba angapindule kwambiri ndi zakudya zopanda oxalate.
Anthu ambiri athanzi amatha kudya zakudya zokhala ndi ma oxalates ambiri popanda mavuto, koma anthu omwe ali ndi vuto la matumbo osokonekera angafunike kuchepetsa kudya kwawo.
Ma oxalates amapezeka pafupifupi m'zomera zonse, koma ena ali ndi kuchuluka kwakukulu ndipo ena ali ndi kuchuluka kochepa kwambiri (20).
Kukula kwa zakudya zomwe zaperekedwa kungasiyane, zomwe zikutanthauza kuti zakudya zina zokhala ndi "oxalate yambiri", monga chicory, zitha kuonedwa ngati oxalate yochepa ngati kukula kwa chakudyacho kuli kochepa mokwanira. Nayi mndandanda wa zakudya zomwe zili ndi oxalate yambiri (zoposa 50 mg pa 100-gramu) (21, 22, 23, 24, 25):
Kuchuluka kwa oxalate m'zomera kumayambira pamlingo wapamwamba kwambiri mpaka wotsika kwambiri. Zakudya zokhala ndi ma oxalate opitilira 50 mamiligalamu pa kutumikira kumagawidwa m'gulu la "oxalate wochuluka."
Anthu omwe amadya zakudya zokhala ndi oxalate yochepa chifukwa cha miyala ya impso nthawi zambiri amafunsidwa kuti adye ma milligram osakwana 50 a oxalate patsiku.
Zakudya zoyenera komanso zopatsa thanzi zimatha kupezeka ndi oxalate yochepera 50 mg patsiku. Calcium imathandizanso kuchepetsa kuyamwa kwa oxalate.
Komabe, anthu athanzi omwe akufuna kukhala ndi thanzi labwino safunika kupewa zakudya zokhala ndi michere yambiri chifukwa chakuti ali ndi ma oxalates ambiri.
Akatswiri athu nthawi zonse amawunika thanzi ndi thanzi lawo ndikusintha nkhani zathu pamene chidziwitso chatsopano chikupezeka.
Zakudya zokhala ndi oxalate yochepa zingathandize kuchiza matenda ena, kuphatikizapo miyala ya impso. Nkhaniyi ikuyang'ana kwambiri zakudya zokhala ndi oxalate yochepa komanso…
Oxalate ndi molekyulu yachilengedwe yomwe imapezeka kwambiri m'zomera ndi anthu. Si michere yofunika kwambiri kwa anthu, ndipo kuchuluka kwake kungayambitse…
Makristalo a calcium oxalate mu mkodzo ndi omwe amayambitsa miyala ya impso nthawi zambiri. Dziwani komwe imachokera, momwe mungapewere komanso momwe mungaithetsere…
Kafukufuku akusonyeza kuti zakudya monga mazira, ndiwo zamasamba ndi mafuta a azitona zingathandize kukweza milingo ya GLP-1.
Kuchita masewera olimbitsa thupi nthawi zonse, kudya zakudya zopatsa thanzi komanso kuchepetsa shuga ndi mowa ndi malangizo ochepa chabe oti musamavutike ndi matenda a shuga.
Ophunzira omwe adanena kuti amamwa malita awiri kapena kuposerapo a zotsekemera zopangidwa pa sabata anali ndi chiopsezo chowonjezeka cha 20% cha matenda a atrial fibrillation.
Cholinga chachikulu cha zakudya za GLP-1 ndikuyang'ana kwambiri zakudya zonse monga zipatso, ndiwo zamasamba, mafuta abwino ndi tirigu wonse, komanso kuchepetsa zakudya zomwe sizinakonzedwe…
