Blood Pressure: Low equals
"slow"
A while back (Daily Dose, 8/8/2003), I wrote an article lambasting the American
Medical Association for lowering its guidelines for healthy blood pressure for
the umpteenth time. To recap, their latest recommendations cite anything over
115/70 (!) as being "high." Just 6 years ago, that number was 140/90
(still plenty low). If their guidelines get much lower, any detectable pulse
will qualify as "high risk" in their eyes...
Aside from the fact that there's no evidence that high blood pressure causes
heart disease (it's often a response to the condition, but not its cause), and
the fact that salt intake is only remotely correlated to hypertension, there's
one more widespread myth about blood pressure that most people - and their
doctors - don't seem to know about:
Your blood pressure can be TOO LOW (115/75 is borderline, if you ask me).
And now, some research from Israel shows just how big of an impact low blood
pressure can have on health - especially upon those who are getting up in
years. According to a recent Reuters online article, a Ben Gurion University
study showed that patients over 70 with what modern standards call "mild
hypertension" actually thought more clearly and creatively than those with
lower blood pressure.
Both men and women in the nearly 500-subject study whose blood pressure was
deemed high enough to warrant treatment with prescription drugs - and also
those with clinically uncontrolled (untreated) hypertension - performed
significantly better on tests of cognitive function, memory, concentration, and
visual retention. Only in tests of verbal fluency was there no meaningful
scoring advantage for the high-BP group...
Those with "normal" blood pressure tested the worst of all three
groups in the study.
Similar studies in younger test populations yielded no difference in
performance based on blood pressure. What's this mean? It means that physicians
need to balance their efforts to control what they perceive as risk factors for
heart disease (namely, BP over 115/75) with patients' quality-of-life concerns
- like mental sharpness and creativity.
In other words, they should stop meddling with the body and mind and let it
find its own equilibrium.

Challenging the salt stigma
Try as I might, I've never been able to make much of a dent on the mainstream's
maligning of salt.
Even though I've shouted at the top of my lungs that salt does NOT cause high
blood pressure except in a very small percentage of people who are abnormally
salt-sensitive, the mainstream continues to portray sodium as a killer to be
shunned at all costs. And with today's ridiculously low guidelines for
"high" blood pressure - there's no reprieve in sight for salt.
But some recent European research has concluded that an extra pinch or two of
salt per day can help the elderly to stay healthy - and that fully 10% of older
folks suffer from a sodium DEFICIENCY! This lack of sufficient daily salt can
cause nervousness, hallucinations, muscle cramps, and even urinary
incontinence.
This, amidst a UK-wide drive to reduce salt in Briton's diets!
In fact, according to a recent Nutraingredients online article, the UK's Health
Minister, Melanie Johnson, rejected a June proposal from Britain's major food
producers to reduce levels of salt in food - for not being stringent enough!
Instead, she issued more than 20 of Britain's food giants a September ultimatum
to reduce the "unacceptably high levels of salt" in their foods.
I guess it takes more than direct scientific evidence to shake the "salt
stigma" in the hallowed halls of parliament, huh? Perhaps she was
suffering from a low-sodium-induced hallucination...
The campaign against salt - and the continuing misinformation of the public
about sodium and high blood pressure - is no less militant on these shores. I'd
hoped that after the last round of downward revisions in the already absurdly
low blood pressure standards, people would have started to question the
conventional wisdom on the topic.
Instead, we seem content with today's most popular salt substitute:
Hypertension drugs.
