U\u017e jste n\u011bkdy sly\u0161eli p\u0159\u00edb\u011bhy vyd\u011b\u0161en\u00fdch pacient\u016f vypr\u00e1v\u011bn\u00fdch o nebezpe\u010dn\u00fdch \u00fa\u010dinc\u00edch p\u0159ed\u00e1vkov\u00e1n\u00ed vitam\u00ednem C? Toto je jeden z mnoha m\u00fdt\u016f, kter\u00e9 ob\u00edhaj\u00ed o tomto popul\u00e1rn\u00edm dopl\u0148ku stravy. Stoj\u00ed za to zn\u00e1t fakta a m\u00fdty o vitam\u00ednu C, aby bylo mo\u017en\u00e9 informovat o zdravotn\u00edm stavu v oblasti zdrav\u00ed. Rovn\u011b\u017e stoj\u00ed za pochopen\u00ed, \u017ee vitamin C nen\u00ed jen \u201el\u00e9k na nachlazen\u00ed\u201c. Tato l\u00e1tka hraje v t\u011ble v\u00fdznamnou roli, jej\u00ed\u017e v\u00fdznam je \u010dasto podce\u0148ov\u00e1n.<\/p>\n

M\u00fdty a fakta o vitaminu C – m\u00fdtus o ledvin\u00e1ch<\/h2>\n

Mnoho z n\u00e1s sly\u0161elo p\u0159\u00edb\u011bhy vyd\u011b\u0161en\u00fdch pacient\u016f, kte\u0159\u00ed byli jejich l\u00e9ka\u0159i varov\u00e1ni p\u0159ed nadm\u011brnou konzumac\u00ed vitam\u00ednu C. Tyto p\u0159\u00edb\u011bhy se t\u00fdkaj\u00ed, ale jsou od\u016fvodn\u011bn\u00e9?<\/p>\n<\/div>\n

\n

Ukazuje se, \u017ee nen\u00ed d\u016fvod panika\u0159it. V\u011bdeck\u00e9 studie neprok\u00e1zaly vztah mezi vitaminem C a tvorbou ledvinov\u00fdch kamen\u016f. To je m\u00fdtus. Ve skute\u010dnosti mohou b\u00fdt ledvinov\u00e9 kameny zp\u016fsobeny jin\u00fdmi faktory, jako je nedostatek ho\u0159\u010d\u00edku.<\/span><\/p>\n<\/div>\n

Ho\u0159\u010d\u00edkov\u00e9 a ledvinov\u00e9 kameny: Zab\u00fdv\u00e1me se m\u00fdty<\/h3>\n

M\u00fdtus ledvinov\u00fdch kamen\u016f zp\u016fsoben\u00fd vitaminem C je roz\u0161\u00ed\u0159en, ale jak se uk\u00e1zalo, je to nepravdiv\u00e9. Ledvinov\u00e9 kameny nejsou spojeny s vitaminem C, ale s ho\u0159\u010d\u00edkem. Je lep\u0161\u00ed \u0159\u00edci s jeho nedostatkem.<\/span><\/p>\n

V roce 2010 komplexn\u00ed studie uk\u00e1zala, \u017ee ka\u017ed\u00fd t\u0159et\u00ed obyvatel Slovenska trp\u00ed zoufal\u00fdm nedostatkem ho\u0159\u010d\u00edku. V na\u0161\u00ed zemi je to podobn\u00e9. A ho\u0159\u010d\u00edk je kl\u00ed\u010dov\u00fdm prvkem br\u00e1n\u00edc\u00ed tvorb\u011b ledvinov\u00fdch kamen\u016f. To je skute\u010dn\u00e1 p\u0159\u00ed\u010dina probl\u00e9mu! Nedostatek ho\u0159\u010d\u00edku m\u016f\u017ee v\u00e9st k nadm\u011brn\u00e9 akumulaci soli v ledvin\u00e1ch, co\u017e zase podporuje tvorbu ledvinov\u00fdch kamen\u016f.<\/span><\/p>\n<\/div>\n

Je vitamin C opravdu magickou slo\u017ekou?<\/h2>\n

Vitamin C, tak\u00e9 zn\u00e1m\u00fd jako kyselina askorbov\u00e1, je organick\u00e1 chemick\u00e1 slou\u010denina, kter\u00e1 hraje kl\u00ed\u010dovou roli v mnoha biologick\u00fdch procesech t\u011bla. Jedn\u00edm z m\u00fdt\u016f, kter\u00e9 st\u00e1le cirkuluj\u00ed, je to, \u017ee vitam\u00edn C je magick\u00fd l\u00e9k na v\u0161echno, od nachlazen\u00ed po rakovinu. A\u010dkoli jej\u00ed role p\u0159i podpo\u0159e imunitn\u00edho syst\u00e9mu je dob\u0159e zdokumentov\u00e1na, nejedn\u00e1 se o v\u0161el\u00e9k pro v\u0161echna onemocn\u011bn\u00ed.<\/p>\n

Vitamin C: Z\u00e1hadn\u00e1 ochrana t\u011bla<\/h3>\n

Dnes, ve sv\u011btle v\u011bdeck\u00e9ho v\u00fdzkumu, bylo prok\u00e1z\u00e1no, \u017ee vitamin C pln\u00ed v\u00edce ne\u017e 100 r\u016fzn\u00fdch \u00fakol\u016f v t\u011ble. Toto je skute\u010dn\u00fd multitaser ve sv\u011bt\u011b vitam\u00edn\u016f. Nam\u00edsto pono\u0159en\u00ed do ka\u017ed\u00e9 z t\u011bchto funkc\u00ed se v\u0161ak zam\u011b\u0159me na dva nejd\u016fle\u017eit\u011bj\u0161\u00ed aspekty.<\/p>\n<\/div>\n<\/div>\n

\n

D\u016fle\u017eit\u00e9 role vitam\u00ednu C v t\u011ble<\/h3>\n

V laboratorn\u00edch podm\u00ednk\u00e1ch bylo opakovan\u011b potvrzeno, \u017ee obsah vitam\u00ednu C v b\u00edl\u00fdch krvinek, kter\u00e9 byly odd\u011bleny od \u010derstv\u00e9 krve, je stokr\u00e1t vy\u0161\u0161\u00ed ne\u017e v jin\u00fdch t\u011blesn\u00fdch tk\u00e1n\u00edch. Granulocyty, tj. B\u00edl\u00e9 krvinky, kter\u00e9 p\u016fsob\u00ed jako druh ohrani\u010dovac\u00ed str\u00e1\u017ee t\u011bla, jsou kl\u00ed\u010dov\u00fdm prvkem v boji proti vet\u0159elc\u016fm, jako jsou viry a bakterie.<\/p>\n

Vitamin c<\/b><\/span> Funguje to jako ochrann\u00fd \u0161t\u00edt a pom\u00e1h\u00e1 chr\u00e1nit t\u011blo p\u0159ed \u00fatoky patogen\u016f. Abychom v\u0161ak tuto funkci efektivn\u011b splnili, pot\u0159ebujeme mnohem v\u011bt\u0161\u00ed mno\u017estv\u00ed vitam\u00ednu C, ne\u017e mnoho lid\u00ed p\u0159edpokl\u00e1d\u00e1. Standardn\u00ed d\u00e1vka 60 mg za den je absolutn\u00ed minimum, ale ani 4000 mg nemus\u00ed sta\u010dit. Ale mus\u00edme se opravdu b\u00e1t nadm\u011brn\u00e9 spot\u0159eby vitam\u00ednu C?<\/div>\n<\/div>\n
\n

Jak bezpe\u010dn\u011b konzumovat vitam\u00edn C b\u011bhem nachlazen\u00ed a ch\u0159ipky<\/h2>\n

Na\u0161t\u011bst\u00ed nen\u00ed d\u016fvod se b\u00e1t konzumace vitam\u00ednu C. Ve skute\u010dnosti je to zvl\u00e1\u0161t\u011b d\u016fle\u017eit\u00e9 b\u011bhem nachlazen\u00ed a ch\u0159ipky, kdy\u017e imunitn\u00ed syst\u00e9m pot\u0159ebuje podporu. Doporu\u010duje se vz\u00edt alespo\u0148 5-6 000 mg vitam\u00ednu C denn\u011b, aby se t\u011blu poskytlo nezbytn\u00e9 prost\u0159edky k boji proti infekc\u00edm.<\/p>\n

Ale nezapome\u0148me na ho\u0159\u010d\u00edk. Minim\u00e1ln\u011b 500 mg ho\u0159\u010d\u00edku denn\u011b, rozd\u011blen\u00e9ho do dvou d\u00e1vek, pom\u00e1h\u00e1 udr\u017eovat zdrav\u00e9 ledviny a zabra\u0148uje tvorb\u011b ledvinov\u00fdch kamen\u016f.<\/p>\n

\n

Z\u00e1kladn\u00ed podm\u00ednky pro v\u00fdhody v\u00fdhod vitam\u00ednu C<\/h3>\n

Posledn\u00ed, ale stejn\u011b d\u016fle\u017eit\u00fd stav je dostate\u010dn\u00e1 hydratace t\u011bla. U\u017e\u00edv\u00e1n\u00ed nejm\u00e9n\u011b 2,5 litru tekutin denn\u011b pom\u00e1h\u00e1 zajistit, aby vitam\u00edn C a ho\u0159\u010d\u00edk byly \u0159\u00e1dn\u011b distribuov\u00e1ny v t\u011ble a budou schopny optim\u00e1ln\u011b vykon\u00e1vat sv\u00e9 funkce.<\/p>\n

Abych to shrnul, nen\u00ed d\u016fvod se b\u00e1t nadm\u011brn\u00e9 spot\u0159eby vitam\u00ednu C. Je to kl\u00ed\u010dov\u00e1 \u017eivina, kter\u00e1 podporuje imunitn\u00ed syst\u00e9m a mnoho dal\u0161\u00edch funkc\u00ed t\u011bla. Ledvinov\u00e9 kameny jsou probl\u00e9mem souvisej\u00edc\u00edm s nedostatkem ho\u0159\u010d\u00edku, nikoli vitaminem C. Proto se b\u011bhem nachlazen\u00ed a ch\u0159ipky nesad\u00edme po dopl\u0148c\u00edch vitam\u00ednu C a ho\u0159\u010d\u00edku, pokud dodr\u017eujeme doporu\u010den\u00e9 d\u00e1vky. P\u00e9\u010de o spr\u00e1vnou hydrataci je dal\u0161\u00edm kl\u00ed\u010dem k udr\u017een\u00ed zdrav\u00ed.<\/p>\n<\/div>\n
