D-vitamin-hypotesen

Vitamin D - Information is Beautiful

Mange hevder at de årlige sesongvariasjoner mht. luftveisinfeksjoner bunner i den årlige variasjon i solinnstråling, og dermed variasjon i hudens produksjon av D-vitamin som dannes ved fotosyntese av kolesterol til kolekalsiferol (previtamin D3).

Hypotesen om sesongvariasjoner ble først fremmet av R.E. Hope-Simpson i 1981 i artikkelen  "The Role of Season in the Epidemiology of Influenza" i tidsskriftet  Journal of Hygiene.

Artkkelen ble republisert i 2010 tidsskriftet Epidemiology & Infection

I 2010 fant den danske professor Carsten Geisler en forklaring på HVORFOR D-vitamin er nødvendig for immunforsvaret; D-vitamin styrer celledelingen av immunceller (T-celler) som kverker uønskede mikrober :

Dermed tok D-vitamin-hypotesen et langt skritt videre mot status som teori…‽

I forbindelse med korona-pandemien har det kommet massiv dokumentasjon på samvariasjon mellom D-vitamin-brist og "smitte"/sykelighet/død av Covid-19…

John Enebak forklarer: Dette er D-vitaminmangel

En grundig gjennomgang av D-vitaminets mangfoldige virkninger finnes i "Vitamin D Endocrine System and COVID-19", Journal of Bone and Mineral Research, 2021-11-08

D-Vitamin-entusiasten Dr. David Grimes har en fyldig oversikt "Covid-19 & Vitamin D. 2020 & 2021 : Nature and anti-nature"

I 2020 publiserte the British Medical Journal en kommentar med fyldig dokumentasjon som styrker D-Vitamin-hypotesen, men det etablerte helsekverket ser ikke ut til å la seg forvirre av fakta…‽ Man lever godt av bestikkelser fra medisin-mafiaen ved å skremme vettet av folk med hjerteinfarkt og hudkreft; for deretter å lokke med vaksine-Nirvana (som aldri kommer…)
