While there is some debate over the merit of aerobic exercise wrt CR and

longevity. Perhaps

it is of value to some as a way to remove excess sodium from their system. I

recall back in the army

being fed salt pills before forced marches and such. Sweat apparently may be

good for something.

I doubt anyone sells salt free ocean fish. My research into the unspecified

solution added to

Wal-mart meat products appears to be sodium diacetate

(anti-microbal/anti-fungal, etc).

I guess that's little consolidation if you're already getting too much sodium. I

only say

appear to be, as their labels are not specific. Perhaps this is another one for

truth in labeling laws.

I did send a note off-list to the food columnist you have clipped before on that

topic (no response).

You can get no-salt added chopped tomatoes and sundry other canned foods at

Wal-Mart but I don't have

a warm and fuzzy that they are serious about health. They apparently are serious

about selling stuff and

people are buying no salt added products when given the choice (even I do).

I repeat, I do not advocate blindly adding salt to anyone's diet, I just resist

the characterization that

it is some evil malefactor. It is probably like sugar and most other poisons,

the danger is in the dose.

FWIW a cute interviewing technique when dining with a job candidate is see if

they salt their food before

or after tasting. Probably even more telling today.

May apologies to any I offend, but there are no simple universal solutions other

than perhaps reducing calories

and some have demonstrated that even that can be overdone.

Be well..

Subject: Re: [ ] Fwd: Re: [bloodpressureline New data

onsalt and BP

: 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.
