You raise some valid points, but, like most issues it is not a matter of "good vs. bad". Using basic facts and common sense clears up a lot of this. No M.D. degree needed.(OK, I confess I have one , but trust me anyway.
1) "Salt" refers to sodium chloride (table salt, Kosher salt, sea salt, etc) in these types of discussions. A common "salt substitute" for example is potassium chloride, also a true salt chemically. I don't use it; too dangerous to dose properly. Simplest quickest way to kill someone: iv injection of an ounce of potassium chloride (10-20% solution; higher concentrations are painful in the vein). There are thousands of natural true salts; mineral combinations of positive and negative ions in stable form, usually solid at room temperature. My limited shelf contains these useful salts: Epsom (mag. sulfate), calcium chloride (Tums), glucosamine sulfate or hydrocloride (essential dancers), iron sulfate (essential for vegetarian dancers), and a little chromium and zinc. These last 2 are micronutrients, in contrast with sodium, magnesium, calcium and iron, which are macronutrient minerals.
Glucosamine is an amino acid salt.
Our bodies continuously and instantaneously regulate levels of potassium and magnesium with mind-blowing acurracy. A 10% deviation of serum level can be enough to kill someone instantly, via cardiac arrest, and leaves very little if trace at autopsy As far as I know, potassium and/or magnesium imbalance has never been excluded as a cause of SIDS.
Another common cause of sudden, unexpectedly death in teenagers and adults is from illegal and legal substances (often prescribed).
Here an MD degree (or a PDR) comes in handy (hint: the PDR is less of a threat to your health). This stuff could all easily could be taught at the high school level, and save many more lives than "sex-ed" which they probably already are experts already.
2) Salt (NaCl) on the other other hand, is loosely regulated by our bodies, by which I mean over hours to days, rather than seconds to minutes. We also tolerate a greater range of blood levels than for potassium and magnesium, easily twice the the range, but a more significant factor is chronobiological. I agree a percentage of the population is "salt senstive" maybe 10% , higher in black men. On the other hand, sodium deprivation triggers profound hormonal responses which are a lot scarier than sodium excess, which reduces these hormonal levels, specifically: epinephrine, rennin, angiotensin 1 and 2, aldosteone, cortisol, ADH, ACTH, CRF, and a few others more obscure or as yet undiscovered) And guess what? Most of the drugs for HBP target these hormones directly ie epinephrine: alpha and beta blockers, renin and angiotensin: beta blockers, ACE inhibitors, ARB's; aldosterone: spironolactone and others. Only the cheap, old fashioned thiazide or loop diuretics target sodium itself, although have minimal impact on blood levels or even total body stores of sodium( a powerful dose might result in loss of 2-3 lbs of body weight, and often symptomatic improvement of leg swelling, bloating, etc).
Calcium channel blockers are more complicated, as is calcium metabolism, but undoubted critical in BP regulation, and likely in many other body functions especially brain function. OK, enough pharmacology, it starts to get tedious and I don't have that much RAM installed (yet!) We won't even begin to think about the pituitary/hypothalamic axis that connects all this stuff intimately with brain activity in general.
3)Back to Earth: every individual is unique; people often crave the thing that is most unhealthy for them, whether it's sugar, fat, or salt. On the other hand, I have noted that many people need MORE healthy sugars (I drink fruit juice when dancing; I just make sure it doesn't contain corn syrup for the sweetener, like most Welch's juices). I also like whole fruit for it's natural slow release of water and potassium. In the hottest part of summer I'll drink V8 or tomato juice for a little extra sodium as well. If I'm at a club, I succumb to pressure and order either hard cider (Fox Barrel is the best: all organic pear apple or berry cider from Colfax, in a beer bottle) or more widely available stuff like that the lemonade in a beer bottle, with a 5% alcohol content, easily metabolized at the rate of one or two an hour, usually around one/hour for females, who metabolize alcohol at half the rate of men; with much individual, genetic difference. I'm sure everyone is fascinated by my drinking habits (well, it's more interesting than my sex llife).
Also, most of us scrawny near vegan dancers benefit from Fish Oil Supplements, as does everyone else on the planet: man, woman, pregnant woman, and children especially (makes them smarter, healthier, and more beautiful).
I hope I have brought some light to the issue. No guarantee, other than I'm not blowing smoke, and I'll take the urine test to prove it on request (although everyone wants my blood lately instead; go figure).
Aloha, Namaste, and Shalom. Edited for brevity and levity.
