As someone who eats strictly keto (low-carb/high-fat), I actually have to make a concerted effort to get enough salt in my diet due to my naturally retaining less water than non-keto people.

This includes making somewhat high-salt food choices wherever reasonable — bacon, pickles, salted butter, cooking with salt in general, etc. — as well as actually adding a salt/electrolyte solution to the water I drink throughout each day. Not only is my blood pressure fine, my most recent blood test sodium levels are actually on the low end of normal (so I've been trying to bump up my salt intake even a bit higher).

Not sure if this says anything interesting about salt, except maybe that carbohydrates could be the real problem that got salt unfairly blamed.

Think the jury is still somewhat "out"...salt sensitivity variations are difficult to test for...

It is fairly well known that reducing salt intake lowers blood pressure...that has been prescribed for decades, with proven results....

Modern carbs, especially those that are "processed", very often have salt added...no doubt we get too much from modern diets....

Sounds as your dilemma is similar to that of humans from the past...which made salt valuable as an item for trade...

To me, the story of salt strongly highlights the difference between science (as in, the results of scientific experiments and careful reasoning), and "science", the things the general public is told science has found by journalists and policymakers.

Not only was there was never a strong scientific basis for telling people to reduce their salt intake, my anecdotal observation is that it's fairly easy to wind up salt-deficient and get symptoms. Sweat contains salt (1g/L), so when exercising or in high temperatures, I need to eat more of it, or I'll get fatigued and physical exertion will become impossible. (Sweat also makes exercise a confounder in studies that look at urinary excretion.)

Meanwhile, foods that we think of as "salty" are usually not actually salty, but rather, are designed to create salt pica. If you start eating potato chips, with most American brands, you'll get to 2000 calories before you get to a typical salt intake (which is 3.5g).

The article specifically points out the scientifically demonstrated opposite relationship between salt intake and blood pressure than the one you have stated here. "It is fairly well known" is nearly always weaselspeak for unfounded opinion, especially in this case.

I'm tired of this from people who discuss eating habits, because personal changes are personal yet many people interpret them as scientific. If you argue about eating on the Internet, step back and understand that your experiences will always vary. Just own that it's an opinion, and I won't begrudge you an opinion. I'll call it wrong, but I'll let you have it. It's your opinion.

I've also been on a mostly-keto diet for the past two years. I don't really pay attention to salt; didn't eat that much to begin with even before keto.

But yes, it's one of those big food myths. I even know a health teacher in the Peace Corps who is telling 6th graders to cut down salt. It's really sad.

Just looked up a bag of chips:

   100g:
     525 cal
     1.5 g salt
Multiply by ~3.8:

  380g:
    2000 cal
    5.7 g salt
Your mileage may vary, but in Norway, a typical bag of chips contains more than 3.5g of salt per 2000 calories.

Looked up a nutrition label online: https://healthyeatingrocks.files.wordpress.com/2012/08/lays-...

    1 oz:
      150 Calories
      180 mg sodium
multiply by 20/3:

    6.667 oz:
      2000 Calories
      1.2g sodium
The kosher salt in my cupboard (ingredients: salt and an anti-caking agent) is 40% sodium by mass (480 mg sodium per 1.2 grams). Or, going by the atomic mass listed here ( http://www.chemicalelements.com/show/mass.html ), sodium chloride should be 39% sodium by mass. Assuming an even 40%, that's 3 grams of salt (NaCl) in 2000 Calories of american potato chips. (Or, assuming the less generous actual amu ratio, 3.05 grams of salt per 2000 Calories ;D )

HOWEVER: the nutrition label also indicates almost twice as much potassium (330 mg) as sodium. If that potassium is also salt (KCl), the chips will handily exceed 3.5 grams of salt per 2000 Calories.
