My suggestion of some groups already having deficiency is conjecture based on little hints here and there; more study is needed. My guesses would be: vegetarians, athletes who avoid processed food, ethnicities with a longer history of eating heavily-salted foods, some elderly, some pregnant women.
I suppose that by subjecting the entire population to an enforced low-sodium diet, and seeing who starts suffering from fatigue and early mortality, we'll find out soon enough.
I disagree. I think if anything there are more people dying because of high blood pressure and other illnesses linked through it than low-sodium issues. Besides, the fix to low-sodium, eat more salt. The fix to high blood pressure, exercise and medication.
yes, unit mismatch. calories x 1.5 mg sodium. for instance, I just had a bag of cheetos from the vending machine. 200 calories, 360 mg sodium. probably not great.
OK. I stick to SI units whenever possible. Avoids confusion.
Are cheetos a very `light' snack? I just took some "Hula Hoops" out of our vending machine and that 34g pack had almost 1000 times the number of calories you report. The "Hula Hoops" have 727 kJ / 174 kcal and 0.3g Sodium, and they also report a "salt equivalent" of 0.8g.
