There's also ample evidence that 1500mg is too low. https://www.webmd.com/food-recipes/news/20140402/cdc-salt-gu....

Unlike white sugar which seems to be bad for humans in nearly any amount, salt is an essential nutrient. I suspect it was so demonized as an attempt to deflect blame off of other food additives such as sugar. Low sodium diets may make sense for people with high blood pressure, but it isn't something that everybody should be doing.

It seems grossly irresponsible to only highlight the dangers of high sodium while ignoring the dangers of low sodium diets.

I recently listened to a great podcast [1] on the importance of salt and its role in proper brain functioning—the host is a tenured professor of Neurobiology and Ophthalmology at Stanford.

Part of the into: Additionally, I examine research findings suggesting that some individuals might benefit from increased intake of sodium and other electrolytes (magnesium and potassium) to enhance mental performance, lessen anxiety, and offset dizziness. Yet, other people may need less sodium. I discuss how you can determine your optimal sodium intake and why sodium intake levels need to be uniquely tailored to an individual’s lifestyle.

I'm a little shocked at only 2 mentions so far of Huberman on this topic. As you know he goes into great detail here, and a panoply of related health issues.

I don't feel like I tried to do a low salt diet, but I don't eat pre packaged foods and normally cut out skipped salt just because it had such a bad rap.

Recently I started drinking a homemade electrolyte and if I miss it for a few days I can really tell. Increasing my salt and potassium has made my head feel better, I don't get dizzy standing up quickly, I got rid of the always thirsty feeling and my circulation is better (fingers aren't cold all the time).

Why did I make this change? My wife had a bunch of tests. The heart doctor said everything was great and to increase salt in the diet. We eat the same and many of the things I listed were mentioned in her appointment - so I figured it would likely be good for me.

Pass the salt.

It's not the total amount of sodium but the concentration of the dose of sodium which will affect your blood pressure.

So if your food tastes salty, you should drink more water to dilute the concentration (and hopefully you won't drink so much water to induce hyponatremia - it's a balancing act).

Later in the above-mentioned YouTube video, the doctor mentions that drinking water before you get that thirsty feeling is better for you.

By the time you get the thirsty feeling, your body has switched over to converting glucose to fructose, etc.
