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.

Hi all-

Just to let you know. I had been buying Tyson frozen chicken tenders

in a 3lb bag because they were convienent and a couple of them cooked

in my steamer in the same amount of time as my veggies. They did

however have the injected salt+stuff broth.

As an alternative Costco has started selling boneless, skinless

chicken breasts individualy wrapped in heavy plastic bags. You can

just freeze the whole package and take out one breast at a time. The

good thing about this is the product has no added sodium or stuff. The

downside is a breast is larger than a tender so I can't just throw it

in with the veggies and have it come out right.

At Whole Foods and Wild Oats I've found a couple of brands of crushed

tomatoes which have very low sodium, Bionature (from Italy I think)

and Westbrea.
