Nadmern\u00e9 u\u017e\u00edvanie vitam\u00ednu D predstavuje probl\u00e9m, lebo patr\u00ed medzi vitam\u00edny rozpustn\u00e9 v tukoch. Telo ho nevyl\u00fa\u010di mo\u010dom, ale ulo\u017e\u00ed ho do tkan\u00edv. Ak ho prijme\u0161 prive\u013ea, za\u010dne sa hromadi\u0165.

\u010eal\u0161\u00edm probl\u00e9mom nadmern\u00e9ho u\u017e\u00edvania je, \u017ee Vitam\u00edn D s\u00edce zv\u00fd\u0161i hladinu v\u00e1pnika v krvi, ale s\u00e1m nerozhodne, kam sa tento v\u00e1pnik ulo\u017e\u00ed.

Pri vy\u0161\u0161\u00edch d\u00e1vkach vitam\u00ednu D preto treba myslie\u0165 aj na jeho kombin\u00e1ciu s K2.<\/p>\n

Zauj\u00edmav\u00e9 v\u00fdsledky priniesli aj \u0161t\u00fadie na star\u0161\u00edch \u013eu\u010foch.<\/a> T\u00ed, ktor\u00ed u\u017e\u00edvali vy\u0161\u0161ie d\u00e1vky vitam\u00ednu D (2 000 a\u017e 4 000 IU denne), mali vy\u0161\u0161ie riziko p\u00e1dov ne\u017e t\u00ed, ktor\u00ed brali ni\u017e\u0161ie d\u00e1vky.

\nVitam\u00edn D nemus\u00ed by\u0165 tak \u00fa\u010dinn\u00fd proti rakovine alebo infarktu, ako sa doteraz verilo<\/p>\n

Ve\u013ek\u00e1 \u0161t\u00fadia VITAL sledovala viac ako 25-tis\u00edc \u013eud\u00ed a nena\u0161la d\u00f4kaz, \u017ee vitam\u00edn D zni\u017euje riziko infarktu, m\u0155tvice alebo rakoviny. Na druhej strane v\u0161ak \u0161t\u00fadia upozor\u0148uje aj na benefit dlhodob\u00e9ho u\u017e\u00edvania. U \u013eud\u00ed, ktor\u00ed u\u017e\u00edvali vitam\u00edn D dlhodobo, klesla pravdepodobnos\u0165 \u00famrtia na rakovinu pribli\u017ene o 25 %.<\/p>\n

\u201eU \u013eud\u00ed, ktor\u00ed u\u017e\u00edvali vitam\u00edn D aspo\u0148 dva roky, sme videli ni\u017e\u0161ie riziko \u00famrtia na rakovinu,\u201c uv\u00e1dzaj\u00fa autori \u0161t\u00fadie.<\/p>\n

\u010eal\u0161ie anal\u00fdzy nazna\u010dili ni\u017e\u0161ie riziko autoimunitn\u00fdch ochoren\u00ed alebo pomal\u0161ie starnutie buniek. No napr\u00edklad pri depresii, pam\u00e4ti \u010di demencii sa \u017eiadny efekt neuk\u00e1zal. V\u0161etky tieto zistenia hovoria, \u017ee\u00a0Vitam\u00edn D m\u00e1 v\u00fdznam, ale nie je univerz\u00e1lny liek.<\/p>\n

D\u00f4le\u017eit\u00fa rolu zohr\u00e1va aj to, ako ho tvoje telo spracuje. Aby sa vitam\u00edn D aktivoval na formu, ktor\u00fa telo dok\u00e1\u017ee vyu\u017ei\u0165, potrebuje hor\u010d\u00edk. Ak m\u00e1\u0161 jeho nedostatok, vitam\u00edn D zostane \u201eneakt\u00edvny\u201c a efekt sa neprejav\u00ed tak, ako by si \u010dakal. Z\u00e1rove\u0148 m\u00f4\u017ee vysok\u00fd pr\u00edjem vitam\u00ednu D e\u0161te viac vy\u010derpa\u0165 z\u00e1soby hor\u010d\u00edka, \u010do sa m\u00f4\u017ee prejavi\u0165 \u00fanavou alebo svalov\u00fdmi k\u0155\u010dmi.<\/p>\n

Hladina vitam\u00ednu sa po\u010das roka men\u00ed, v tomto obdob\u00ed m\u00e1 testovanie najv\u00e4\u010d\u0161\u00ed zmysel<\/p>\n

Zauj\u00edmav\u00fd detail sa t\u00fdka aj merania hladiny vitam\u00ednu D v krvi. T\u00e1 sa po\u010das roka v\u00fdrazne men\u00ed. Po lete alebo dovolenke pri mori m\u00f4\u017ee\u0161 ma\u0165 v\u00fdborn\u00e9 hodnoty. Naopak, po zime b\u00fdva hladina \u010dasto na minime. Preto m\u00e1 najv\u00e4\u010d\u0161\u00ed zmysel da\u0165 si test na konci zimy, ke\u010f s\u00fa z\u00e1soby najni\u017e\u0161ie. Vtedy zist\u00ed\u0161, \u010di telo naozaj potrebuje doplnky.<\/p>\n

Autori \u0161t\u00fadie zistili aj to, \u017ee strava ti \u010dasto dod\u00e1 menej vitam\u00ednu D, ne\u017e by si \u010dakal. V\u00e4\u010d\u0161ina potrav\u00edn obsahuje len mal\u00e9 mno\u017estvo. V\u00fdnimku tvoria mastn\u00e9 ryby ako losos, sardinky alebo obohaten\u00e9 potraviny, napr\u00edklad mlieko \u010di rastlinn\u00e9 n\u00e1poje.<\/p>\n

Preto sa doplnky zdaj\u00fa ako jednoduch\u00e9 rie\u0161enie. Len\u017ee pr\u00e1ve tu sa robia chyby. Ve\u013ea \u013eud\u00ed si mysl\u00ed, \u017ee \u201eviac znamen\u00e1 lep\u0161ie\u201c, no pri vitam\u00edne D to neplat\u00ed.<\/p>\n

Autori namiesto toho odpor\u00fa\u010daj\u00fa sledova\u0165 d\u00e1vku, dr\u017ea\u0165 sa odpor\u00fa\u010dan\u00fdch hodn\u00f4t a neprekra\u010dova\u0165 horn\u00fa hranicu bez d\u00f4vodu.<\/p>\n

\u201eAk nem\u00e1\u0161 konkr\u00e9tny zdravotn\u00fd probl\u00e9m, pravdepodobne nepotrebuje\u0161 viac ne\u017e 600 a\u017e 800 IU denne,\u201c odpor\u00fa\u010daj\u00fa odborn\u00e9 usmernenia.<\/p>\n

Z\u00e1rove\u0148 plat\u00ed, \u017ee jedlo je lep\u0161\u00ed zdroj ne\u017e tabletky. Kombin\u00e1cia rozumnej stravy a pobytu na slnku \u010dasto pokryje tvoje potreby. Doplnky maj\u00fa zmysel hlavne vtedy, ke\u010f m\u00e1\u0161 potvrden\u00fd nedostatok alebo patr\u00ed\u0161 do rizikovej skupiny.<\/p>\n

Najlep\u0161ie rie\u0161enie sa nach\u00e1dza niekde v strede. Netreba vitam\u00edn D ignorova\u0165, no z\u00e1rove\u0148 by si to nemal prehna\u0165 a hlavne pochopi\u0165 s\u00favislosti, ako funguje v tele, \u010do ovplyv\u0148uje jeho \u00fa\u010dinok a pre\u010do nie v\u017edy prinesie v\u00fdsledok, ktor\u00fd by si \u010dakal.<\/p>\n
