- Ngaphambi kokundizela emkhathini, iNASA yaphoqa osomkhathi ukuthi badle inani elincane lobumba ukuqinisa amathambo esimweni esingenasisindo. Ngenxa yenhlanganisela yamaminerali (bona amaqiniso athakazelisayo ngamaminerali) obumbeni, i-calcium equkethe imuncwa kangcono ngumzimba kune-calcium emsulwa.
- Uvithamini B wokugcina owaziwa watholakala ngo-1948.
- Ukuntuleka kwe-iodine kungaholela ezifweni ze-thyroid kanye nokukhula kwengane.
- Ukunxephezela ukuntuleka kwe-iodine, usawoti one-iodized waqala ukukhiqizwa, ukusetshenziswa kwawo okwaholela ekwandeni kwe-IQ emaphakathi emhlabeni wonke.
- Ngokushoda kukavithamini B₉ (i-folic acid ne-folate), kunengozi yokukhubazeka kombungu kwabesifazane abakhulelwe.
- Ezimweni ezimbi kakhulu, itiye lenaliti likaphayini lingaba ngumthombo ocebile kavithamini C. Itiye elinjalo lenziwa izakhamizi zaseLeningrad ezivinjezelwe, njengoba, njengoba wazi, zabhekana nendlala embi.
- Isibindi sebhere lePolar siqukethe uvithamini A omningi kakhulu ukuthi ukusetshenziswa kwawo kungaholela ekufeni. Ngalesi sizathu, kuyisiko ukuthi ama-Eskimo angcwabe ukuze izinja zingasidli isibindi.
- Izifundo eziningi zesayensi zikhombisile ukuthi uvithamini C awusizi ukunciphisa ubungozi bemikhuhlane.
- Ukuthola i-potassium overdose, umuntu kuzodingeka adle cishe ubhanana we-400 ngemizuzwana engama-30.
- Iqiniso elithandekayo ukuthi ukunikezwa kopelepele kuqukethe uvithamini C ophindwe izikhathi ezingama-400 kunokuphakwa kwamawolintshi.
- Ukweqisa kukavithamini K kuholela ekwandeni kwama-platelet ne-viscosity yegazi.
