@photognut interesting article. Thanks for posting it.
I'm being lazy so skipped to the diabetes section. This is
important information. And makes me think I should start supplementing with salt daily (because I'm on LCHF diet, don't eat processed foods, and don't add salt to my food). Here it is...
Salt and Type 2 Diabetes Mellitus
In patients with type 2 diabetes mellitus, a low sodium diet
has been associated with increased cardiovascular and
all-cause mortality.7 Even moderate salt reduction may lead
to increased activation of the sympathetic nervous system
and renin-angiotensin-aldosterone system, and insulin
resistance.
A cohort study7 enrolled 638 diabetic persons who were
consistently followed for a period of 9.9 years. Their baseline
urinary sodium excretion levels
were 184 73 mmol/24 hours,
which remained constant throughout
the study duration. Urinary
sodium levels were inversely
related to the all-cause mortality
rate (P < .001) and cardiovascular
mortality rate (sub-hazard ratio
, 0.65; confidence interval
[CI], 0.44-0.95; P ¼ .03). Each
100 mmol increase in the urinary
sodium excretion led to a decrease
in all-cause mortality of 28% (95%
CI, 6-45; P ¼ .02). This study
implies a potential contraindication
to a low sodium diet not only in
those with type 2 diabetes mellitus but also by extension in
the general population because of the widespread prevalence
of type 2 diabetes mellitus. This leads to the question, are the
current dietary guideline recommendations for a low sodium
diet in the general population (including type 2 diabetes
mellitus) appropriate? The limitation index of these data is
that the results are based on a cohort study examining urinary
sodium excretion levels versus a randomized controlled trial
of patients receiving identical diets, with the only variation
being the amount of sodium intake.
