Urinary sodium excretion and salt intake are not independently associated with 24-hour blood pressure variability (BPV), according to a study.
Tan Lai Zhou and colleagues used data from 2,652 participants in the Maastricht Study to evaluate whether urinary sodium excretion and salt intake are associated with 24-hour BPV. Participants adhered to a seven-day low- and high-salt diet (50 and 250 mmol NaCl/24 hour, respectively) with a washout period of 14 days.
The researchers found that 24-hour urinary sodium excretion was not associated with 24-hour systolic or diastolic BPV (β, per 1 g/24-hour urinary sodium excretion: 0.05 mm Hg [95 percent confidence interval, −0.02 to 0.11] and 0.04 mm Hg [95 percent confidence interval, −0.01 to 0.09], respectively). There were no significant differences observed in mean difference in 24-hour systolic and diastolic BPV between the low- and high-salt diet (0.62 mm Hg [95 percent confidence interval, −0.10 to 1.35] and 0.04 mm Hg [95 percent confidence interval, −0.54 to 0.63], respectively).
"Our results do not indicate that salt restriction would be an effective strategy to lower BPV," the authors write.

Salt restrictions can kill you!

Deficient Iodine found in table salt might be causing thyroid enlargement in their children. This causes all kinds of problems including allergies.
Does using iodized salt alleviate that problem?
This one is near and dear to me.
This one goes back and forth.
- Salt causes high blood pressure
- Salt doesn’t cause high blood pressure
- Salt causes higher blood pressure if you have high blood pressure issues.
etc..
Somewhere the truth lives.
“Salt restriction doesn’t seem to help change the blood pressures changes we have through the day.”
Yep, Dr. Berry has been quite clear on this. And, in fact, there are only 2 ways to really endanger yourself with salt:
1) Force-feed it to yourself by using far more than needed to make food taste good.
2) Eliminate it to the level that is currently recommended, or less.
Eating the amount needed to make food taste good (roughly two to three times the recommended amount) pretty much gives us the ideal level of salt...which makes sense or humans wouldn’t be alive today as all of these ‘medical experts’ telling us to not eat salt were not around for the first 99.99% of human history.
It's all about the dosage. Many substances that are essential to life can, nonetheless, impair health or even prove fatal if ingested in excessive quantities.
What is the objective?
Unclear what you are asking. Are you asking: By what mechanism could reducing sodium intake possibly reduce blood pressure?
Regards,
Idk, reducing salt really helps lower my blood pressure. I’m not religious about it though.
You needn't school me on this. You are simply repeating what I wrote.
Or are you merely attempting to indicate assent? And repeating this for the benefit of other readers?
Keep your adrenochrome in check you will do far more good.
I'm afraid that most casual readers will not find that advice very helpful. Instead, they need simple, concrete advice like, "Put down the salt shaker!" which they can easily understand and follow (not that that would be the correct advice - I'm only using it as an example).
Regards,
I feel that my use of boldface was appropriate.
"It's all about the dosage. Many substances that are essential to life can, nonetheless, impair health or even prove fatal if ingested in excessive quantities."
Though, you're right: We posters here often respond to other posters with whom we are actually in agreement, and adopt a lecturing or condescending tone which can easily seem directed at the wrong person.
I suppose that I am as guilty of that as others.
Sorry, too!

SAlt restriction may not lower blood pressure, but too much salt ( sodium ) can spike it. Been monitoring my BP daily after stroke. Systolic was averaging about 110 for 2 weeks. One night it jumped to 160. Turns out it was BBQ sauce that did it. Didn’t realize how much sodium is in that and ketchup. 2 teaspoons contained 300mg. I must have had at least 1800mg.
I know this for myself having tried cutting back sodium intake dramatically for no effect. They have been telling us for decades to reduce salt intake to reduce blood pressure while knowing that is effective in a small percentage of cases. They argue that that small percentage who see an improvement is a reason to give everyone the same instructions. Insanity.
The real cause of high blood pressure seems to be insulin resistance for most people. The way to fix that is to go to a low carb diet with intermittent fasting. Worked fantastic for me.
Doctors seem to think a low carb diet with intermittent fasting is not possible or some kind of heroic act of will power. You know what takes heroic will power? Getting up from a meal still hungry because you are counting calories trying to lose weight. I eat until full when I eat, I just restrict the times I eat, don’t eat carbs and make sure I get a lot of healthy natural fat (no vegetable oils except EVOO).
I would say that our bodies do an excellent job regulating salt. If our ancestors didn’t evolve to tolerate wide variations in salt intake, they would not have made it.
Outside of a small percentage of the population, salt restriction has no effect on blood pressure. This is well known in the literature, but doctors keep telling everyone to restrict salt. It is insanity.
