Thank you, Lara!
I was already wondering... if it is indeed SO hard to make vitamin D by 
being outside in a normal way and not half-naked until almost being 
sunburnt... how could people ever have been non-deficient?!
Those in favour of vastly supplementing whole populations... how do you 
explain this? What has changed so dramatically over the course of which 
number of years for us to now all be in danger of breaking our bones? 
Wouldn't it be preferable by far to figure out how much daylight we need and 
which fats and other foods to eat, to get a healthy level *without* 
supplementing?
Supplementing is common, but it is not normal. Supplementation is fighting 
symptoms of unhealthy behaviour. What behaviour would make for a turn for 
the better?
It is funny indeed... In the Netherlands D-recommendations have become 
*less* panicky these last years! Quite a story on borstvoeding.com, about a 
quarter of an hour per day being enough, when combined with a good 
nutritional status.
I think Lara is absolutely right to put question marks to this and to be 
suspicious about the intentions of the pharmaceutical industry behind it...

Warmly,

Marianne Vanderveen IBCLC, Netherlands
