Re: Fwd: Re: [bloodpressureline New data on salt and BP

[Guest guest]

Hi JW, I knew I could count on your contradictory response. Is this news?

For the record I do not advocate blindly eating salt. I only want people to be

aware that general population studies are only true in " general " ... Individuals

need to know their personal metrics and act accordingly. Since my BP this

morning

measured 90/60 perhaps I need to add some more salt?

There is such as thing as too little sodium, as I and others have experienced.

Now

apparently there's a large enough market that Gatorade is offering a product

targeting endurance athletes. Don't tell the football players who drink pickle

juice

or eat mustard before long practices to avoid sodium, you could hurt them if

their

electrolyte levels get too out of whack.

I agree that processed foods contain too much salt but I don't eat that poop. I

further

speculate that they increase salt content even more as the ad lib taste buds get

desensitized to all that salt. If there's any folks here who still believe it's

OK

to blindly eat mainstream processed food, wake up and read the label.

However I hope most lurking here already get it.

BACKGROUND: Abundant evidence indicates that a high sodium intake is

causally

related to high blood pressure, but debate over recommendations to

reduce

dietary sodium in the general population continues. A key issue is

whether

differences in usual sodium intake within the range feasible in free-

living

populations have clinical or public health relevance. OBJECTIVE: We

examined the

relation between blood pressure and urinary sodium as a marker of

dietary intake.

DESIGN: This was a study of 23104 community-living adults aged 45-79

y.

RESULTS: Mean systolic and diastolic blood pressure increased as the

ratio of urinary

sodium to creatinine increased (as estimated from a casual urine

sample),

with differences of 7.2 mm Hg for systolic blood pressure and 3.0 mm

Hg for

diastolic blood pressure (P < 0.0001) between the top and bottom

quintiles. This

trend was independent of age, body mass index, urinary

potassium:creatinine, and

smoking and was consistent by sex and history of hypertension. The

prevalence

of those with systolic blood pressure >/= 160 mm Hg halved from 12%

in the

top quintile to 6% in the bottom quintile; the odds ratio for having

systolic

blood pressure >/= 160 mm Hg was 2.48 (95% CI: 1.90, 3.22) for men

and 2.67 (95%

CI: 2.08, 3.43) for women in the top compared with the bottom

quintile of

urinary sodium. Estimated mean sodium intakes in the lowest and

highest quintiles

were approximately 80 and 220 mmol/d, respectively. CONCLUSIONS:

Within the

usual range found in a free-living population, differences in urinary

sodium,

an indicator of dietary sodium intake, are associated with blood

pressure

differences of clinical and public health relevance. Our findings

reinforce

recommendations to lower average sodium intakes in the general

population.

I just posted it because I ran acrossed it. Hope that's ok.

We're also well aware that some people need more salt.

BTW, in my high school, no one drank any water during a game, just wet their mouth and spit it out.

Of course, endurance athletes may need special care, but I think my take is longevity in this group.

I also don't tell football players who expect to play pro ball and make a lot of money not to grow their bodies to 300#.

That particular post was from a noted authority on HTN.

: I didn't see anything in JW's post of a salt study that was aimed at

or addressed to you personally.

I understand JW's frustration because I personally am finding it harder and

harder to shop without finding salt in virtually everything. I like to use

plain canned crushed tomatoes to make my tomato based sauces and am lately

finding that there's all of a sudden, salt added (I guess I'll have to

switch to tomato paste until they start adding salt to that too). As noted

recently I've had to stop buying supermarket poultry because they're now

injecting it with a saline solution. So even though I buy very few

processed foods, the things I used to be able to buy without concern seem to

now be " salted " . Also I eat canned sardines and salmon for their many

benefits and convenience and they of course have always been and probably

will forever be salted (I remember you said that WalMart sells unsalted

canned fish but I don't live near a Wal Mart).

I can't find ANY hummous without salt added and so if I want unsalted

hummous I guess I'll have to make my own. For those of us who perhaps don't

have the time/inclination to make everything from scratch, it can be

frustrating. IMHO a bad practise (one of many) of the food industry.

Salt can always be added for those who want more of it; but can only with

difficulty, be removed from food.
