Johan se oli keväällä tässä ketjussa tiedossa, että Etelä-euroopassa vanhuksilla on puuteita D-vitamiinissa. Luulo on tässä kohtaa väärin, etenkin vanhusten kohdalla. Eivät vanhukset siellä etelässäkään makaa aurinkorannalla.
A new study has found an association between low average levels of vitamin D and high numbers of COVID-19 cases and mortality rates across 20 European countries.

"Italy and Spain have both experienced high COVID-19 mortality rates, and the new study shows that
both countries have lower average vitamin D levels than most northern European countries. This is partly because people in southern Europe, particularly the elderly, avoid strong sun, while skin pigmentation also reduces natural vitamin D synthesis.
The highest average levels of vitamin D are found in northern Europe, due to the consumption of cod liver oil and vitamin D supplements, and possibly less sun avoidance. Scandinavian nations are among the countries with the lowest number of COVID-19 cases and mortality rates per head of population in Europe."
"While I think it is important for people to know that vitamin D deficiency might play a role in mortality,
we don't need to push vitamin D on everybody," said Northwestern's Vadim Backman, who led the research. "This needs further study, and I hope our work will stimulate interest in this area. The data also may illuminate the mechanism of mortality, which, if proven, could lead to new therapeutic targets."
Backman is careful to note that
people should not take excessive doses of vitamin D, which might come with negative side effects. He said the subject needs much more research to know how vitamin D could be used most effectively to protect against COVID-19 complications.
WHO declared SARS-CoV-2 a global pandemic. The present aim was to propose an hypothesis that there is a potential association between mean levels of vitamin D in various countries with cases and mortality caused by COVID-19. The mean levels of vitamin ...

Tuolta löydät taulukon, josta nähdään, että Suomessa D-vitamiinitasot ovat selvästi keskimääräistä korkeammat.
Oleellista tässä nyt on se, mikä on jo moneen kertaan sinullekin kerrottu. On selvä ero D-vitamiinin vajauksessa ja sitten D-vitamiinin reippaassa yliannostuksessa. Suomessa D-vitamiinilisiä suositellaan (vanhuksille vieläpä tupla-annos) ja myös syödään. Sille, että pitäisi alkaa vetää kymmenkertaisia annoksia ei löydy mitään erityistä näyttöä.
No ne kuuluisat tieteentekijät, jotka ovat näitäkin asioita tutkineet. Ja eiköhän me uskota nyt ennemmin niitä kuin jotain foorumin "varmaa tietoa".
