I-Vitamin C inokubandakanywa kunyango phantse zonke izifo, kubandakanywa unyango lwentsholongwane yentsholongwane - kungekhona nje kwiimeko ezincinci kodwa naxa ikhosi inzima kwaye ukuhlala esibhedlele kuyimfuneko.
I-Vitamin C isebenza ngexesha lobhubhani wentsholongwane
IVithamin C ise-China nase-USA-ubuncinci isetyenziswa kwezinye iikliniki ukunyanga usulelo oluqatha lwentsholongwane egazini njengomzekelo iB. Covid-19 esetyenziswayo kwaye ingalungela kakhulu ukukhulula iinkqubo zempilo ngexesha loqhambuko lomkhuhlane - hayi kancinci kuba. ngexabiso layo eliphantsi.
Nangona kunjalo, ivithamin iyaqhubeka nokujongelwa phantsi ngabasebenzi bezonyango abaqhelekileyo kunye namaziko asemthethweni okutya. Kuba kangaphi sisiva okanye sifunda isivakalisi sokuba isondlo sisinika zonke iivithamini ngokumangalisayo-kuquka ivithamin C-ukuba ukungenisa okongeziweyo akuzisi naziphi na izibonelelo? Kude noko, njengoko kubonisiwe ngokuphindaphindiweyo.
I-Vitamin C inciphisa ixesha kwiiyunithi zokhathalelo olunzulu
Sele sibhale apha (iVithamin C inciphisa ixesha kwiiyunithi zokhathalelo olunzulu) ukusuka kuhlalutyo lwe-meta ukusuka ngo-2019, apho kwafunyaniswa ukuba ulawulo lomlomo lwevithamin C lunokunciphisa ubude bokuhlala kwiiyunithi zokhathalelo olunzima kwaye ke umntu kufuneka asoloko thatha i-vitamin kwizigulane ezihambelanayo -C-isipho kufuneka sicinge.
Kwinqaku elidityaniswe ngasentla, sichaza ukuba abantu abagulayo, ngokukodwa, banezinga eliphantsi levithamini C okanye banesidingo esongeziweyo se-vitamin C kwaye kuya kufuneka bathathe malunga ne-4 grams ye-vitamin C yonke imihla (ngokwezifundo ezahlukeneyo) ukuze ukufikelela kumanqanaba C aqhelekileyo kumntu ophilileyo.
Kungcono ukuthatha ivithamin C kwiidosi eziphezulu ngamaxesha obunzima
Kwi-meta-analysis ekhankanywe ngasentla, i-1 ukuya kwi-3 grams ye-vitamin C ngosuku iholele ekubeni uhlale ixesha elifutshane kwiyunithi yokunyamekela kakhulu, kunye ne-vitamin C nayo inciphisa ixesha elifunekayo lokungena komoya wokufakelwa. Ngokujonga ezi zixa zokuthatha, i-100 mg yevithamin C ecetyiswa yimithombo esemthethweni kwaye ihlala ichazwa njengezandi ezaneleyo ezithandabuzekayo.
Ngokunxulumene nempilo ye-cardiovascular, kudala kwaziwa ukuba iidosi eziphezulu ze-vitamin C ziyafuneka. Sibonise apha (i-Vitamin C iphucula imisebenzi ye-vascular) i-meta-analysis evela kwi-2014. Kuyo, abaphandi abasekelwe kwizifundo ze-44 ezicwangcisiweyo kunye nokulawulwayo baphetha ukuba abantu abaneengxaki ze-cardiovascular system bazuza kuphela kwiidosi ze-vitamin C ezingaphezu kwe-500 mg ngosuku.
Ukusetyenziswa kwevithamin C kwizifo ezosulelayo kuxoxwe ngayo ukusukela ngo-2004 mva nje - ngelo xesha ngokujonga ubhubhane we-SARS. UHarri Hemilä ovela kwiDyunivesithi yaseHelsinki wabhala kwiJenali yeAntimicrobial Chemotherapy ngelo xesha ukuba ivithamin C yonyusa ukuxhathisa kweenkukhu kwi-avian coronavirus. Izifundo ezilawulwa yi-placebo kubantu zibonise ukuba ubude bemikhuhlane eqhelekileyo bunokuncitshiswa ngoncedo lwe-vitamin C, ngoko kunokucingelwa ukuba umngcipheko wentsholongwane yentsholongwane yendlela yokuphefumula ixhomekeke kumanqanaba e-vitamin C.
Uphononongo oluthathu olulawulwayo lukwafumanise ukuba abantu abanakufane babe nenyumoniya xa besongeza ngevithamin C.
Idosi ephezulu yevithamin C infusions kwizigulana zeCovid-19
Uphononongo lwezonyango lwe-vitamin C lwenziwe e-China ukusuka ngoFebruwari ukuya ekupheleni kukaSeptemba 2020, ekhokelwa nguDkt ZhiYong Peng, unjingalwazi we-Intensive Care Medicine kwisibhedlele saseZhongnan seYunivesithi yaseWuhan eHubei.
Abathathi-nxaxheba bonke babenekhosi eqatha ye-Covid-19 kwaye babekukhathalelo olunzima kunye nesifo esibukhali sokuphefumla. Bafumana nokuba yi-12 g yevithamin C ngokutofelwa kabini ngemini kangangeentsuku ezisi-7 okanye i-placebo. Babefuna ukufumanisa ukuba ivithamin C inokunciphisa ixesha lokuphefumla, inciphise ukufa, ithintele ukusilela kwamalungu kwaye icothise ukuqhubeka kokudumba.
Liyinyaniso elokuba, le vitamin ayizange ikwazi ukulinciphisa ixesha lokuphefumla, yaye ayizange inciphise nokufa. Nangona kunjalo, kwaphawulwa ukuba umsebenzi wamaphaphu wezigulane eziphathwe nge-vitamin C ziphuculwe ngokuqhubekayo (into ebizwa ngokuba yi-oxygenation index yanda ngokuqhubekayo), okwakungenjalo kwiqela le-placebo. Amanqanaba okudumba ayephantsi kwakhona kwiqela le-vitamin C kuneqela le-placebo.
Ngelixa iziphumo bezingekho ntle njengoko umntu ebenethemba, unyango lwevithamin C lunezibonelelo ezicacileyo ekungafanelanga ukuba ziphoswe.
Iingcali ze-Corona zicebisa le dose ye-vitamin C
Ngomhla woku-1 kuMatshi ka-2020, upapasho lwe-Shanghai Medical Association yaseTshayina Ijenali yeZifo ezosulelayo ) yafunda isindululo sonyango lwe-Covid-19-ephuhliswe ziingcali ezingama-30 ze-corona ezivela eShanghai.
Baye bavavanya ukulawulwa komthambo wevithamin C kwi-Covid-19 kwizigulana ezingama-300 kwaye bacebisa le nkqubo ilandelayo yonyango lwe-Covid (ukongeza kunyango lwesiqhelo): Kuxhomekeka kubuzaza besi sifo, isigulana kufuneka sinikwe phakathi kwe-50 kunye ne-200 mg. kavithamini C ngosuku Iikhilogram zobunzima bomzimba zilawulwa ngemithambo, nto leyo kumntu omdala onobunzima obuzi-z. B. I-70 yeekhilogram ingaba yi-3.5 ukuya kwi-14 g yevithamin C.
Yile ndlela i-vitamin C isebenza ngayo kwi-sepsis kunye ne-pneumonia
Xa i-sepsis isenzeka (usulelo lwenkqubo olulandelwa yi-immune response response), izixa ezikhulu ze-cytokines (izithunywa ezivuthayo) zikhululwa. Ngelo xesha, kukho ukuqokelela okuqinileyo kweeseli ezithile zokukhusela (i-neutrophilic granulocytes) kwimiphunga, ekhokelela ekutshatyalalisweni kwe-pulmonary capillaries.
Ngokwezifundo zangaphambili - ngokutsho kwabaphandi abajikeleze uDkt Peng kwinkcazo yabo yophando - ngokufanelekileyo ukukhusela ngokuchanekileyo le nkqubo. I-Vitamin C iphinda incede ukuthintela ukuqokelelwa kolwelo kwimiphunga eyenzeka ngenyumoniya ngokunciphisa ukuqokelelwa kweegranulocyte kwizicubu zemiphunga ezichazwe ngasentla.
Yile ndlela i-vitamin C isebenza ngayo kwingqele kunye nomkhuhlane
Kukwayaziwa ukuba ivithamin C (xa ithathwa ngomlomo) iyalinciphisa ixesha lengqele kwaye inokuthintela imikhuhlane, ngakumbi kubantu abasebenzayo ngokwasemzimbeni. Kwimeko yokugqibela, inani lemikhuhlane lingancitshiswa ngesiqingatha ngenxa yevithamin C. Isiphumo sothintelo sasingcono nge-500 mg ngosuku kune-50 mg ye-vitamin C kuphela.
Kolunye uphononongo, umzekelo, umkhuhlane wawungaphantsi kakhulu ukuba abathathi-nxaxheba bathatha i-1 g yevithamin C rhoqo ngeyure (iiyure ezi-6) ekuqaleni kwesigulo kunye ne-1 g ye-vitamin C kathathu ngemini kwiintsuku ezilandelayo. .
Kwisishwankathelo sakhe se-vitamin C kunye nezifo ezosulelayo, umphandi we-vitamin C waseFinnish uHarri Hemilä ubhala ukuba ixesha lokubanda (ngokwezifundo ezibini) linokuncitshiswa ngokukhethekileyo ngeedosi eziphezulu ze-6 ukuya kwi-8 g ye-vitamin C ngosuku Iingxelo zokuba ivithamin C ayiloncedo kwingqele mhlawumbi inxulumene nezifundo apho iidosi ze-vitamin C ebeziphantsi kakhulu (umz. 200 mg) zaye zasetyenziswa.
I-Vitamin C ikhulula ikhosi ye-pneumonia
I-Hemilä ikwalatha kwizifundo ezithathu ezilawulwayo apho ivithamin C yakwaziyo ukuthintela inyumoniya kunye nezinye izifundo ezibini ezilawulwayo apho unyango lwevithamin C lwezisa isiqabu kwinyumoniya ekhoyo (enxulumene nomkhuhlane), umzekelo ukunika izigulane ezisi-9 kuphela endaweni yeentsuku ezili-12 kwafuneka hlala esibhedlele iintsuku.
Izifundo zezilwanyana ezineentsholongwane zomkhuhlane wehagu (iintsholongwane ze-H1N1) zabonisa ukuba ukongezwa kweginseng ebomvu kunye nevithamin C esebenzayo iiseli zomzimba (iiseli ze-T kunye neeseli ze-NK), zithintele iintsholongwane ekuphuhliseni kwaye zinciphise iinkqubo zokudumba ezinxulumene nentsholongwane kwimiphunga, ngenxa yoko ziyanda. izinga lokusinda.
Ukunqongophala kwe-Vitamin C kwandisa umngcipheko womkhuhlane
Olunye uphononongo lomkhuhlane lubonise ukuba ukunqongophala kwevithamin C kwandisa umngcipheko wokubamba umkhuhlane kwaye kunokuwenza ube mandundu ngakumbi ukuba unomkhuhlane. Kwimeko ye-sepsis okanye i-syndrome yokuphefumula yokuphefumula (i-ARDS), kukho iziphumo zophando ezingahambelaniyo ukuza kuthi ga ngoku, ngokutsho kukaHemilä kwinqaku lakhe lokuphonononga.
"Ungaze uthathe iidosi eziphezulu ze-vitamin C!"
Nangona zonke ezi zibonakaliso zeziphumo zevithamin C zivakala zithembisa kakhulu kwaye nangona ivithamin C ingenzi monakalo nakwidosi ephezulu (kunye nokusetyenziswa kwexesha elifutshane kunye nonyango olucetyiswayo apha), oku kulandelayo kuphinda kuphindwe kwakhona njengemantra:
“Amathamo asetyenziswa kwizifundo angaphezulu kwedosi yemihla ngemihla ecetyiswayo kwaye okwangoku akukho bungqina baneleyo bokuxhasa ukusetyenziswa kweedosi eziphezulu zevithamin C kwinyumoniya. Akufanele ke ngoko uthathe iidosi eziphezulu zevithamin C, njengoko oku kunokuba neziphumo ebezingalindelekanga ezifana nesifo sorhudo.
Isiphumo esisecaleni Urhudo lolokwexeshana
Isiphelo: Ngoko ke, kuyenzeka (nokuba oku akukangqinwa ngokwenzululwazi nge-100 leepesenti) ukuthomalalisa okanye ukuthintela isifo esiyingozi nesinokuthi sibulale ngedosi ephezulu yevithamin C. Nangona kunjalo, akukhuthazwa ngamandla ukuba uzame ngenxa yokuba unokufumana urhudo. Isifo sohudo, esingenzeki kuwo wonke umntu, ngaphezu koko - ukuba i-hypersensitivity enjalo kufuneka ibe khona - iguqulwa emva kokumisa i-vitamin C kwaye ingashiyi umonakalo ongunaphakade.
Ezinye iziphumo ebezingalindelekanga ezihlala kuthiwa zinxulunyaniswa needosi eziphezulu zevithamin C, ezinjengomngcipheko owongeziweyo wamatye ezintso, azihambelani nonyango lwexesha elifutshane lwe-vitamin C ngexesha lobunzima. Okwesibini, kukho yonke into ebonisa ukuba umngcipheko wamatye kwizintso kunye nedosi ephezulu yevithamin C (nethi iphantsi kakhulu) yonyuka kancinci ngenxa yevithamin C kodwa inezinye izizathu, umzekelo, B. iyanda kuphela xa ungabonelelwanga ngemagnesium kwi ngexesha elinye okanye baphelelwe ngamanzi emzimbeni. Unokufunda iinkcukacha kwinqaku lethu malunga nomngcipheko wamatye ezintso kwi-vitamin C.
Thatha i-vitamin C ngamaxesha obunzima
Kufanelekile ke ngoko ukuqinisekisa ukuba kukho ivithamin C eyiyeyona ifanelekileyo ngamaxesha obunzima. Ngezantsi sibonisa ukutya okutyebileyo kwevithamin C ebonisa ukuba ukutya okunempilo okugcweleyo kunye neziqhamo ezininzi kunye nemifuno kunokubonelela ukuya kuthi ga kwi-500 mg yevithamin C ngosuku.
Oku kutya kutyebile ngakumbi kwivithamin C
Iziqhamo, imifuno nemifuno ziyimithombo esemagqabini yevithamin C, ngoxa ukutya kwezilwanyana phantse akunavithamin C. Oku kutya kulandelayo kunovithamini C okhethekileyo (kusoloko kwi-100 g yokutya okukrwada, ngaphandle kokuba kuchazwe ngenye indlela):
Imifuno, imifuno, kunye neesaladi
- Parsley 160 mg
- igalikhi yasendle 150 mg
- I-pepper ebomvu 120 mg
- I-Brussels ihluma i-110 mg
- Kale 100 mg
- I-Broccoli iphekwe kwi-90 mg
- I-Cress / watercress 60 mg
- Kohlrabi 60 mg
- Isipinatshi 50 mg
I-sauerkraut ekrwada 20 mg (ngoko ke ayityebi kuvithamin C njengoko abaninzi becinga; umxholo wevithamin C ude ube “phezulu” njengakwikhaphetshu emhlophe ephekiweyo; ikhaphetshu ekrwada emhlophe ino-45 mg wevithamin C).
I ziqhamo
- Ijusi ye-Sea Buckthorn 260 mg
- Iicurrants ezimnyama 170 mg
- Ipapaya 80 mg
- Amaqunube 60 mg
- Iiorenji / iiLamuni / iOrenji entsha / iJusi yeLemon 50 mg
Siphinde sabonisa iingcebiso ze-7 zokubonelela nge-vitamin C efanelekileyo apha ( Indlela i-vitamin C inceda ngayo intliziyo). Ezi ngcebiso ziquka iingcebiso malunga nokuba ujonge ntoni xa udla ukutya okunevithamin C ukuze ujabulele ubuninzi bevithamin C. Ngenxa yokuba i-vitamin C iyakwazi ukuphuphuma ngokugcinwa, ukuvezwa kobushushu, iindlela zokuthutha ezide, ukupholisa, njl.
Khetha izongezo ze-vitamin C ezikumgangatho ophezulu
Nangona kunjalo, kuba kunzima ukufumana amayeza afanelekileyo evithamin C yeegram ezininzi ngosuku nokuba nokutya okutyebileyo kwiziqhamo kunye nemifuno kwaye, kwimeko yokugula, umntu uhlala engakuthandi ukutya kwaye utya kancinci, umntu uthatha ivithamin. C ukuba kwicala elikhuselekileyo ngendlela yamalungiselelo e-vitamin C, umzekelo ukusuka kwi-acerola cherries, i-hips rose okanye i-sea buckthorn berries.
Kodwa nangezi ncediso zendalo ze-vitamin C, isixa se-vitamin C esithathayo sihlala silinganiselwe. Amalungiselelo edosi ephezulu kavithamin C ke ahlala equlathe i-ascorbic acid (ivithamin C esulungekileyo evela kwilabhoratri) - mhlawumbi ngokukodwa okanye njengomxube kwimithombo yendalo ye-vitamin C.
