Kafukufuku wina akusonyeza kuti kuwonjezera mavitamini D anu kungathandize kuchepetsa vuto lanu la khansa. Zopezeka mu mawonekedwe othandizira, vitamini D ndi vitamini ofunika kwambiri pantchito yoteteza thupi komanso imathandiza kuchepetsa kutupa . Pamene maphunziro a vitamini D ndi katetezedwe ka khansa apangitsa zotsatira zosiyana, pali umboni wina wakuti anthu okhala ndi vitamini D apamwamba angakhale ndi chiopsezo chochepa cha mitundu ina ya khansa.
Pakalipano, chithandizo chachikulu cha sayansi cha ntchito ya vitamini D's yomwe imawathandiza popewera khansa imachokera ku zofufuza zapamwamba (maphunziro omwe amafufuza makhalidwe enieni a anthu ena). Mwachitsanzo, mu lipoti limodzi, ofufuza adapenda kafukufuku wa masewero owonetsera mavitamini D omwe ali ndi chiwerengero cha makumi asanu ndi limodzi (63) komanso chiopsezo cha khansa, kuphatikizapo khansa yamtundu , kansa ya m'mawere , ndi khansara ya prostate . Malinga ndi lipotili, kafukufuku ambiri adawonetsa kuti anthu okhala ndi mavitamini O okwanira ambiri amakhala ndi vuto la khansa ya m'munsi.
Mayesero angapo a zachipatala (kafukufuku omwe amayesa zotsatira za mankhwala ena kapena chithandizo chamankhwala) atha kugwiritsanso ntchito vitamini D ndi ngozi ya khansa. Mwachitsanzo, kafukufuku wina anapatsa amayi 1,179 a thanzi labwino kuposa zaka 55 kuti athandizidwe:
- Gulu limodzi linapatsidwa 1,400 mpaka 1,500 mg ya tsiku ndi tsiku
- Gulu limodzi linapatsidwa calcium komanso 1,110 UU wa vitamini D
- Gulu limodzi linapatsidwa maloboti
Pambuyo pa zaka zinayi, omwe adatenga kashiamu ndi vitamini D adasokonezeka kwambiri kwa mitundu yonse ya khansa, poyerekeza ndi omwe anatenga calcium yekha kapena placebo.
Komabe, mayesero ena am'chipatala apeza kuti kudya mavitamini D kumathandiza kuchepetsa chiopsezo cha khansa ya m'mawere ndi khansa yoyipa kwambiri-mitundu iŵiri ya khansa yofala kwambiri ku United States.
Chifukwa chosowa thandizo la kafukufuku, ndizodziwikiratu kuti kutenga vitamini D zowonjezereka kungachepetse chiopsezo cha khansa.
Kuti izi zitheke, National Cancer Institute sichiteteza kapena kutsutsa kugwiritsa ntchito vitamini D zowonjezereka pofuna kuchepetsa chiopsezo cha mtundu uliwonse wa khansa.
Komabe, popeza kukhala ndi mavitamini D omwe ndi ofunikira kwambiri ndikofunika kwa thanzi lonse, akatswiri ambiri azachipatala amalimbikitsa kuti kuwonjezeka kwa vitamini D kudya. Ngakhale kuti vitamini D imapezeka mu zakudya zina, monga nsomba zonenepa ndi mkaka wolimba, ndipo zimatha kupangidwa ndi thupi panthawi ya dzuwa, kutenga mavitamini angakhale njira zowonjezera zowonjezera mavitamini D.
Ngati mukufuna kugwiritsira ntchito vitamini D zowonjezereka kuti muteteze khansa yanu-kapena cholinga china chilichonse cha thanzi-lankhulani ndi dokotala wanu za kupeza chowonjezera chimene mukufuna. Ndikofunika kuzindikira kuti kudziletsa nokha ndi kupewa kapena kuchepetsa kusamalidwa kosatha kapena njira zothandizira kungakhale ndi zotsatira zoopsa.
