Ingabe Ama-Vegans Adinga Izithasiselo? Izakhamzimba Ezibalulekile kanye Nokucatshangelwa

Cha, zonke izakhamzimba ozidingayo ukuze uthole ukudla okunempilo kwe-vegan zingatholakala kalula nangokuchichimayo ngokudla okusekelwe ezitshalweni, mhlawumbe ngokuhlukile okukodwa okuphawulekayo: uvithamini B12. Le vithamini ebalulekile idlala indima ebalulekile ekugcineni impilo yesimiso sakho sezinzwa, ukukhiqiza i-DNA, nokwenza amangqamuzana egazi abomvu. Kodwa-ke, ngokungafani nezakhi eziningi, i-vitamin B12 ayikho ngokwemvelo ekudleni kwezitshalo.

I-Vitamin B12 ikhiqizwa amagciwane athile ahlala emhlabathini kanye namapheshana okugaya ezilwane. Ngenxa yalokho, itholakala ngamanani abalulekile ngokuyinhloko emikhiqizweni yezilwane njengenyama, ubisi namaqanda. Nakuba le mikhiqizo yezilwane ingumthombo oqondile we-B12 kulabo abawudlayo, ama-vegans kufanele afune ezinye izindlela zokuthola lesi sakhi esibalulekile.

Kubantu abadla imifino, kubalulekile ukunaka ukudla kwe-B12 ngoba ukuntula kungaholela ezinkingeni ezingathi sína zezempilo ezifana ne-anemia, izinkinga zemizwa, nokukhubazeka kwengqondo. Ngenhlanhla, kunezindlela ezisebenzayo zokuqinisekisa amazinga e-B12 anele ngaphandle kokudla imikhiqizo yezilwane. Ukudla okuqinisiwe kuyindlela eyodwa; ubisi oluningi olusekelwe ezitshalweni, okusanhlamvu kwasekuseni, kanye nemvubelo enomsoco kunothiswa nge-B12. Enye inketho izithasiselo ze-B12, ezinconywe kakhulu ukuze kuqinisekiswe ukuthi uthola okwanele kwalesi sakhi esibalulekile. Lezi zithako ziqukethe i-B12 etholakala kubhaktheriya, efana nendlela efakwa ngayo ekudleni okuqinisiwe, okwenza kube umthombo osebenzayo nothembekile.

Ingabe Ama-Vegans Adinga Izithasiselo? Umsoco Obalulekile Nokucatshangwayo Agasti 2025

I-Vitamin B12

Ngempela, i-vitamin B12 ibalulekile emisebenzini ehlukahlukene ebalulekile emzimbeni. Kuyathakazelisa ukuthi lesi sakhi esisodwa sidlala indima ebalulekile ezinqubweni eziningi ezahlukene. Ukusuka ekugcineni impilo yamangqamuzana ezinzwa kuya ekusizeni ukukhiqizwa kwe-DNA namaseli abomvu egazi, kuyacaca ukuthi kungani i-B12 ibaluleke kangaka. Iphinde isekele ukusetshenziswa kwe-iron futhi ifake isandla ekuhlelweni kwamasosha omzimba kanye nokulawulwa kwemizwelo. Uma ukhathazekile ngamazinga akho e-B12, ikakhulukazi uma udla imifino noma i-vegan, kuwumqondo omuhle ukuqapha okudlayo noma ucabangele izithasiselo, njengoba zitholakala kakhulu emikhiqizweni yezilwane.

E-UK, amazinga aphansi kavithamini B12 ayinkinga evamile, ikakhulukazi kubantu abadala. Ucwaningo lubonisa ukuthi ukushoda kwe-vitamin B12 kudlangile kuwo wonke amaqembu obudala obuhlukahlukene, ngokungafani okuphawulekayo phakathi kwabantu abasha nabadala. Ngokuqondile, ucwaningo lwathola ukuthi cishe amaphesenti ayisithupha abantu abangaphansi kweminyaka engama-60 bahlushwa ukuntula i-B12. Kodwa-ke, leli phesenti likhula kakhulu kubantu abadala, cishe ngamaphesenti angama-20 alabo abaneminyaka engaphezu kwengama-60 abathintekayo.

Indaba ihlanganiswe namaqembu athile, njengama-vegans. Ngokusho kokutholwe kwakamuva, cishe amaphesenti ayi-11 ama-vegans e-UK ashoda nge-vitamin B12. Lokhu kuveza ukukhathazeka okubalulekile kulabo abalandela ukudla okusekelwe ezitshalweni, njengoba i-B12 itholakala kakhulu ekudleni okususelwa ezilwaneni.

Inhlolovo Kahulumeni Yezokudla Nezokudla Kazwelonke yango-2016 ihlinzeka ngemininingwane eyengeziwe ngokudlanga kokuntuleka kwe-B12 kuzo zonke izinhlobo zabantu zeminyaka yobudala. Ucwaningo lwembula ukuthi cishe amaphesenti amathathu amantombazane aneminyaka engu-11 kuya kwengu-18 abonisa amazinga aphansi e-B12 ebonisa ukuntula. Kubantu abadala abaneminyaka engu-19 kuya kwengama-64, izinga lokuntula licishe libe ngamaphesenti ayisithupha. Kubantu abadala asebekhulile, izibalo ziphakeme: cishe amaphesenti amahlanu amadoda angaphezu kweminyaka yobudala be-65 kanye namaphesenti ayisishiyagalombili abesifazane abaneminyaka yobudala efanayo athintekayo ngenxa yokuntuleka kwe-B12.

Ukuqaphela okuthakazelisayo okuhlobene nalolu daba ukuguqulwa kokuqukethwe kwezakhi zokudla kwezilwane phakathi neminyaka. Ngokuqondile, imikhiqizo eyenziwe ngengulube ibonise ukwehla okukhulu kwamazinga e-vitamin B12 uma kuqhathaniswa nasekuqaleni kwawo-1990. Ukwehliswa kulinganiselwa ukuthi kungaphansi kokukodwa kokuthathu kunangaphambili. Lokhu kuncipha kudalwe izinguquko ezenzweni zokudla kwezilwane; izingulube azisaphakelwa inyama yezilwane, okuyinto ngokomlando enomthelela emazingeni aphezulu e-B12 enyameni yazo. Lokhu kushintsha kwezinqubo zokuphakela kungase kube nomthelela wokuqukethwe kwe-B12 ephansi emikhiqizweni yengulube, okuqhubekisela phambili ingozi yokuntuleka phakathi kwalabo abathembele kulokhu kudla ukuze bathathe i-B12.

Kafushane, ukushoda kwevithamini B12 kuyinkinga ephawulekayo e-UK, ngokuvama okuhlukahlukene kuwo wonke amaqembu eminyaka kanye nemikhuba yokudla. Kubantu abadala asebekhulile kanye nabantu abalandela ukudla kwe-vegan, ukuqapha nokubhekana namazinga e-B12 kubalulekile ekugcineni impilo nokuvimbela izinkinga ezihlobene.

Ivithamini D

I-Vitamin D ibalulekile ekugcineni amathambo, amazinyo, nemisipha enempilo, futhi isekela eminye imisebenzi ebalulekile yomzimba. Ngokuvamile okubizwa ngokuthi “ivithamini yokukhanya kwelanga,” ivithamini D ikhiqizwa lapho isikhumba sichayeka elangeni. Kodwa-ke, e-UK, ukuntula kwe-vitamin D kwande kakhulu. Lokhu kubonakala ikakhulukazi kubantu abanesikhumba esimnyama, abadinga ukukhanya kwelanga okwengeziwe ukuze bakhiqize uvithamini D owanele ngenxa yokuqukethwe okuphezulu kwe-melanin esikhumbeni sabo, okumunca imisebe ye-UVB ngendlela engasebenzi kahle. Ukwengeza, amazinga okuntuleka akhuphuka phakathi nezinyanga zasebusika lapho kunokukhanya kwelanga okuncane nezinsuku ezimfushane.

Entwasahlobo nasehlobo, abantu abaningi e-UK bangakhiqiza uvithamini D owanele ngokuchayeka kafushane nje elangeni. Ngokuvamile, ukuchayeka imizuzu emihlanu kuya kwengama-25 kwanele ukuhlangabezana nezidingo zomzimba. Lesi sikhathi esifushane sokuchayeka elangeni sinciphisa ingozi yemiphumela emibi njengokushiswa yilanga nomdlavuza wesikhumba. Abantu abanesikhumba esikhanyayo ngokuvamile badinga isikhathi esincane sokuchayeka uma kuqhathaniswa nalabo abanesikhumba esimnyama. Ukuze uthole impilo engcono kanye nokunciphisa ingozi yokushiswa yilanga, indlela “kancane futhi kaningi” yokuchayeka elangeni ngokuvamile iyanconywa.

I-Vitamin D ikhona ngezinhlobo ezimbili eziyinhloko: i-D2 ne-D3. Ifomu ngalinye linemithombo ehlukene nemithelela ekukhetheni ukudla.

Lapho ucubungula ukwengezwa kwe-vitamin D, kubalulekile ukuphatha ukudla ngokucophelela. Ukweqisa kwevithamini D kungaholela ezindabeni zezempilo, njenge-hypercalcemia, lapho umzimba udonsa i-calcium eningi, okungase kubangele ukulimala kwezitho namathambo. Ukuze uvimbele le miphumela emibi, uHulumeni wase-UK weluleka ukuthi umthamo wansuku zonke wevithamini D akufanele udlule ama-microgram ayi-100. Lesi sincomo sisiza ukuqinisekisa ukuthi abantu bathola izinzuzo zikavithamini D kuyilapho begwema izingozi ezihlobene nokusetshenziswa ngokweqile.

Omega-3s

Ama-omega-3 fatty acids angamafutha abalulekile imizimba yethu engakwazi ukuwakhiqiza ngokwawo, ngakho-ke kufanele siwathole ngokudla kwethu. Lawa mafutha abalulekile emisebenzini ehlukahlukene yomzimba kanye nempilo yonke. I-Omega-3s iyingxenye ebalulekile yolwelwesi lwamaseli ethu, ithonya ukusebenza kwamaseli kuwo wonke umzimba. Badlala indima ebalulekile ekukhiqizeni ama-hormone, ekulawuleni ukuvuvukala, futhi okungenzeka kunciphise ingozi yesifo senhliziyo.

Ngaphandle kwe-iodine eyanele, indlala yegilo ayikwazi ukukhiqiza la mahomoni ngokuphumelelayo, okuholela ezinkingeni zezempilo ezingase zibe khona njenge-hypothyroidism ne-goiter.

Iodine ngokwemvelo ikhona ngamanani ahlukahlukene endaweni ezungezile, futhi ukutholakala kwayo ekudleni kuncike kakhulu emazingeni e-iodine yomhlabathi. Imithombo yokudla evamile ye-iodine ihlanganisa:

Kunombono oyiphutha ovamile wokuthi ama-vegans asengozini yokuntuleka kwe-iodine ngenxa yokugwema imikhiqizo yobisi. Kodwa-ke, iodine ayikho ngokwemvelo obisini kodwa yengezwa ngezithako ze-iodine eziphakelwa izinkomo kanye nezibulala-magciwane ezine-iodine ezisetshenziswa ekukhiqizweni kobisi. Ngakho-ke, okuqukethwe kwe-iodine emikhiqizweni yobisi akuyona ukubonakaliswa okuqondile kwamazinga e-iodine yemvelo obisini.

Kuma-vegans, kubalulekile ukufaka ukudla okunothe nge-iodine noma izithasiselo ekudleni kwabo ukuze baqinisekise ukuthi bayahlangabezana nezidingo zabo ze-iodine. Ukusetshenziswa kwezimila zasolwandle ngezikhathi ezithile noma ukusebenzisa usawoti one-iodine kungasiza ukubhekana nokushoda okungenzeka.

Ukudla okunconyiwe kwe-iodine kwansuku zonke kubantu abadala ngama-microgram ayi-140. Lokhu ngokuvamile kungafezwa ngokudla okuhlukahlukene okuhlanganisa imithombo ye-iodine njengokhula lwasolwandle nosawoti one-iodine.

Nakuba i-iodine idingeka empilweni, ukudla ngokweqile kungaholela ekungasebenzini kahle kwegilo, njenge-hyperthyroidism noma i-hypothyroidism, nokuzuza isisindo. Umkhawulo ophezulu wokudla i-iodine ngokuvamile ubhekwa njengama-microgram angu-500 ngosuku, futhi ukweqa leli nani kungase kube yingozi empilweni. Abantu abaningi bangahlangabezana nezidingo zabo ngaphandle kokufinyelela lo mkhawulo ophezulu ngokusebenzisa i-iodine ngokulinganisela.

Kafushane, iodine ibalulekile empilweni yegilo kanye nokusebenza kwe-metabolic. Ngokufaka ukudla okunothe nge-iodine ekudleni kwakho noma ukukhetha imikhiqizo eqinile, ungagcina amazinga anele futhi usekele impilo yonke.

I-calcium

I-calcium iyimaminerali ebalulekile ekugcineni amathambo namazinyo aqinile, kanye nokusekela imisebenzi ehlukahlukene yomzimba njengokufinyela kwemisipha, ukudluliswa kwemizwa, nokujiyisa kwegazi. Kulabo abalandela ukudla kwe-vegan, kunemithombo eminingi esekelwe ezitshalweni ukuhlangabezana nezidingo ze-calcium.

Ukudla kwe-vegan okuhlanganiswe kahle okuhlanganisa izinhlobonhlobo zokusanhlamvu, ama-pulses, amantongomane, kanye nembewu kunganikeza i-calcium eyanele. Nansi eminye yemithombo engcono kakhulu esekelwe ezitshalweni ye-calcium:

Imifino ethile efana nesipinashi, i-chard, ne-beet eluhlaza iqukethe i-calcium kodwa futhi inamazinga aphezulu ama-oxalates, izinhlanganisela ezingavimbela ukumuncwa kwe-calcium. Nakuba le mifino isengaba nomthelela ekwakhiweni kwe-calcium iyonke, i-calcium eyinikezayo ayimuncwa kalula umzimba uma iqhathaniswa nemifino ye-oxalate ephansi.

Ukuze uthole ukumuncwa kwe-calcium okuphelele, kuyazuzisa ukudla imifino enokuqukethwe kwe-oxalate ephansi, okufana nalokhu:

Ngokuthakazelisayo, i-calcium evela kule mifino eluhlaza ene-oxalate encane imunca cishe ngokuphindwe kabili kune-calcium esebisini lwenkomo. Ngaphezu kwalokho, le mifino inikeza izinzuzo ezengeziwe zokudla okunomsoco, okuhlanganisa i-fiber, i-folate, i-iron, nama-antioxidants, angekho obisini lobisi.

Ukudla okunempilo kwe-vegan kungahlangabezana kalula nezidingo ze-calcium ngokudla okuhlukahlukene okusekelwe ezitshalweni. Ngokufaka imithombo efana nobisi lwezitshalo eziqinile, i-tofu, imifino enamaqabunga, amantongomane, nembewu, ungaqinisekisa ukuthi uthola i-calcium eyanele. Ukunaka izinhlobo zemifino edliwayo kanye nokufaka izinketho ze-oxalate ephansi kungathuthukisa ukumuncwa kwe-calcium kanye nempilo yonke.

I-Selenium ne-Zinc

I-Selenium ne-zinc kungamaminerali abalulekile adlala indima ebalulekile ekugcineni impilo yonke, futhi ngenhlanhla, ungathola amanani anele ekudleni okuhlelwe kahle kwe-vegan ngaphandle kwesidingo sezithasiselo.

I-Selenium

I-Selenium ibalulekile emisebenzini ehlukahlukene yomzimba, okuhlanganisa ukuvikelwa kwe-antioxidant, umsebenzi we-thyroid, nokusekelwa kwamasosha omzimba. Itholakala ekudleni okuningana okusekelwe ezitshalweni, kodwa eminye imithombo icebile kakhulu nge-selenium:

Zinc

I-Zinc ibalulekile ekusebenzeni kwamasosha omzimba, ukwakheka kwamaprotheni, ukuphulukiswa kwesilonda, kanye nokuhlanganiswa kwe-DNA. Izinhlobonhlobo zokudla okusekelwe ezitshalweni zinikeza i-zinc eyanele:
