Health professionals recommend diets that are high in fruits and vegetables since these contain potassium which is known to normalize blood pressure. The recommended dietary quantity of potassium is actually higher than sodium. They must be balanced in physiological processes such as nerve transmission.
But itâs notoriously difficult to get people to change their diets. Regular table salt (sodium chloride) is very inexpensive relative to potassium salts so commercial processed foods contain a huge preponderance of sodium.
Hereâs information about potassium including cautions about adding additional potassium to the diet.
For people with normal kidney function, Lite Salt (R) brand is a good option since it contains 50% potassium chloride and 50% sodium chloride. I have cooked with this for many years. Itâs more expensive than regular table salt but still a trivial expense. Much cheaper than fruits and vegetables (which we eat also, of course) and easier to get for people who live in food deserts.
The macroeconomic impact of high blood pressure relative to the slight cost of adding potassium to the diet is huge.

The electrolyte composition of blood serum is similar to that of seawater. 140/5 meq/dl (sodium/potassium) is typical. Sodium is much higher than potassium. But sodium is much more abundant in the diet.
Note that too much potassium can be toxic. Donât over do it.
OTOH, the macro-economic impact of not making life-style choices that directly contribute to high blood pressure, such as over-eating and failing to exercise, might avoid having to self-medicate with potassium, not that having a sufficient level of magnesium (and D3, and K2) arenât important to maintaining oneâs immune system.
Iâve been using low sodium salt for years. The price difference is vanishingly small, irrelevant. Itâs great for treating muscle cramps. BTW, my blood pressure was normal even before using it.
Just to mess up the thread, my bloodwork always comes back showing potassium a hair above the ânormalâ range. I donât live on bananas either. Everything else is not only ânormalâ, but most are dead center in the ânormalâ range.
Somehow Iâve always thought âlow sodium saltâ is kind of like ânot wet waterâ. Salt is, I thought, by definition NaCl. Itâs right there in the formula.
But arenât we talking about NaCl in this thread? Thatâs how I took goofyâs remark. What the vast majority of people talk about when they mention âsalt.â
Would it have helped it he said, âcommon salt is, I thought, by definition NaClâ or âtable salt is, I thought, by definition NaClâ?
@MataroPete, yes, that is what a chemist would say.
@Goofyhoofy here is a practical exercise in salts.
If your garden tomatoes have blossom end rot itâs a sign they donât have enough calcium. But common agricultural lime (crushed limestone which is calcium carbonate*) is slow to dissolve. You need a soluble, quick-acting calcium salt.
Dissolve an eggshell (or a Tums tablet) in vinegar, making sure that there is excess solid so the solution is not acidic.
Acid + base â salt + water
CH3COOH + CaCO3 â> CH3COO Ca (calcium acetate) + CO2 (bubbles) + H2O
Water the tomato plants with the solution of calcium acetate salt. That will heal the blossom end rot.

*Quicklime (CaO) is made by heating limestone. Slaked lime has water added to quicklime â itâs Ca(OH)2
Iâm always amazed at the number of people who donât measure their blood pressure somewhat frequentlyâŚsay, once or twice a week and at different times during the day. Reserving the ritual for the annual physical.
Then again, there are probably plenty of folk around who donât bother with an annual physical either, so thereâs thatâŚ
Looking at the cross section of the population that I saw as patients in my office, Iâd say fewer than the numbers who brushed and flossed diligently and effectively. Something that didnât necessarily change when the consequences of high BP and/or periodontal disease became apparent.
@WendyBG âŚthis may or may not have been discussed with you but, post surgery and if your experience is anything like my husband, you might find yourself on BP meds⌠along with everything else⌠in order to keep your BP artificially low. At least, temporarily. To protect the valve etc.
Husband had never experienced high blood pressure prior. Measured periodically (just like weight) since heâs black, and both parents developed quite hard to manage high blood pressure in their senior yearsâŚand he has had a working lifetimeâs experience of folk walking round with preventable/treatable diseases they were unaware of. Whether itâs a consequence of now taking bp meds, or that length of dacron he has in lieu of his dodgy ascending aorta, heâs become quite salt sensitive. Now that he measures his BP every morning, the effects of a saltier-than- usual meal the night before will usually become quite apparent.
Yeap, I am find with sodium and use regular salt. I have the potassium so I can caringly cook for friends who must limiit their sodium and for whom potassium is OK within reason.
Not quite everyone, manifestly. Or, at least, not concerned enough to do the best they can with their alloted lifespan/the genetic hand theyâve been dealt.
