Such is a good point. Though it should be noted that even it such
climates
people often have rather low serum 25 OH vitamin D levels due to
indoors
living or how they dress or just the effect of aging on the skin
and it ability to convert cholesterol into the provitamin.
It would be interesting to see the number for age, morbidity, and
mortality from influneza and then compare the serum 25 OH vitamin
D3 levels in such a land as yours.

It takes huge doses in number of international units for this to be a
problem
in most in the population. For most it will likely take huge doses
plus
lots of sun to reach a problem levels. Your concern is overblown.
Don't get me wrong it would NOT for example suggest rPTH therapy and
high dose vitamin D as a wise action.
Vitamins do need to studied in combination with related chemicals i.e.
vitamin C with flavonoids and antioxidants. There are issue of
antioxidant recycling that come into play. Lester Packer had a nice
discussion of the antioxidant network in a couple of journals
some years ago.
Vitamins E, K, D, A all have interlocking properties such that
vitamin E status affects vitamin K levels in personal with marginal
standard diets, vitamin D and A have somewhat opposing actions,
vitamin K helps to prevent ectopic calcifications, etc.
Nor should vitamins and diet be seen as the only knob that
should be turned and altered.
Pete there are excesses on both sides. Pete the problem with
your side is that it seeks to shove it point of view down the
throats of the rest of the population by force of law.
Rather than permitting the market place of ideas to
sort out the issues with time (generations) and ample research
at all the doses and combinations possible.
Hopefully we can carefully avoid your positions on all issues even
those where you are right as even there you are more wrong than
right.
I do agree with you that JOHN is a nut even when he is right.
If JOHN didn't exist you'd need to create him as a strawman.
