I just posted a link to where some of it started. See, the USA doesnt
really 'study' this, they just know a segment are salt related.
The actual testing Don and I had done validate that many will have
hypertension (HTN which John tried to be cute about not translating).
It also showed clearly that it is not 'universal' which John probably
does not know.
It's in the excerpt that it's safe to reduce salt for all of us and
that it was too expensive to conduct detailed studies.
What was funny was you could tell from the chart data, if I was at sea
or inport and you could see if it was a short inport (3-4 days or less)
or if it was a week or so, a spike 2 days before I pulled out to sea
again.
I don't recall the exact details of how the weeks went but you had to
write down a diary of everything you ate and how much of it. If you
used a can of something, how much of the can you ate that meal. You
had to take BPs with a home monitor every 2 hours and record the time
of eating and the BP time as well as a rough of what you had done in
the last 15 minutes before the BP was taken. Don was able to give
better values because he was not on a ship at sea.
There was a week of 'eat normally and record it' then a week of
seriously reduced sodium (I think the aim was 750mg a day?) then a week
of salt bomb (4,000mg a day or higher) then a median week in there
aimed at 2,400mg a day.
My values stayed the same no matter the sodium intake but shifted based
on stress. Don showed stress and salt relation. Don also reacted at
USDA 2,400mg a day but minimal reaction at 2,000 a day and none at
1,800 a day. Aiming for 1,500 a day gives him a little wriggle room if
at the bar, he wants a salty snack. His data shows that the occasional
(truely, not more than once a month) salt bomb is ok.
