Rapid Response:

Why should we control physiology?

I enjoyed very much reading Margaret MacCartney's article. It is
obviously critic of advertisement and what the industry (those who have
something to gain from selling) does with science (theoretically science
should be above commercial interests, right?).

I still get surprised at the lengths to which we, as medical doctors, ignore physiology.

If kids are in schools that limit access to water, do we have to
promote water intake, or should we promote more open schools?

Should we stress the importance of listening to one's thirst (of
hunger, or tiredness...) or should we prescribe a rigid fixed value of 2
litres/day?

Many people already force kids to eat. Are we also going to force
them to drink?

As doctors we should evaluate the individual whom we are caring for.
And adapt our recommendation like doctor Axel Ellrodt says.

As policy makers we should stress the importance of drinking if you
feel thirsty (what a world we are in, where you have to remind people to
live!).

I do feel curious about what you think of fluoridation of water. We
don't have it here, in Portugal, and I'm happy about it. It doesn't seem
sensible to me to ingest something which biggest effect is local, in
direct contact between dentin and fluor...
