Salt intake over years is not the same as salt intake over a month making this study meaningless in terms of long term heath impacts.

Nope.

If you're wondering why you're so downvoted, your reply of "Nope." is at best lacking of any substance in a discussion and at worst offensive.

This is with every bottle you drink? So basically once I figure out the amount, I should put that much in every time I get a fresh glass?

Hey. If you're drinking lots of water and getting lots of cramps, don't ask people on the internets. Ask a physician, right? If there's something wrong with your kidneys, say, you won't make it better until you figure out what it is.

Very often people on the internet have more expertise in things than a physician. Also, physicians are often overkill for minor problems, the system would be overloaded if we went to them for every little thing.

For the past year I've been on a low sodium diet, not so easy to achieve. After reviewing the renal physiology I learned about years ago re: sodium and calcium regulation, I'll testify it's every bit as complex as I remember and then some. I'll be interested in reading the articles the newspaper report is based on, but ATM not sure how much the new findings contradict (vs. extend) what's thought to be true about the…

A random theory, if you will: glucocorticoids have a weak affinity for the mineralocorticoid receptors (aldosterone, salt and water retention). The increased salt reabsorption caused by this could cause an osmotic gradient driving calcium excretion. It sounds a bit too complicated though, where a transporter would fit in nicely.

I don't have any direct info re: mineralocorticoid effect on renal reabsorbtion of calcium, however the interaction of sodium and calcium has been studied as it is important in kidney disease, for example kidney stones, and osteoporosis as well. Here is an article on an excellent site that discusses some of the significant aspects of sodium/calcium regulation: http://kidneystones.uchicago.edu/does-too-much-protein-incre....

Nope.

The US recommended salt intake is limited to 1.5g to 2.3g grams of salt depending on some risk factors. Their 'low' intake was 6g and high was 12grams / day. https://sodiumbreakup.heart.org/how_much_sodium_should_i_eat So, I am saying almost 5x the recommended limit for a month might not generalize very well. Sorry, 'Nope' is not going to cut it. Further, the human body climatizes to various situations over time suck…

A lot of the cross-talk in the whole salt/sodium debate is caused by conflating salt (sodium chloride) with sodium, one of its constituents.

The US daily recommended sodium intake is 1.5-2.3g. The sodium component of sodium chloride is about 40%, so that's more like 3.75-5.75g of salt per day. Still lower than the study, but putting the higher recommended amount right around the lower study amount.

(I consume up to an extra teaspoon of salt each day to make sure I'm getting at least 5000mg of sodium so I don't start passing out at an inconvenient moment, on advice of a cardiologist)

You'll notice the same behavior from long distance runners, cyclists, hikers, etc. At some point you start feeling dehydration because you're missing electrolytes. If your water intake isn't salted or packed with minerals in some other way, it just makes you thirstier and thirstier. Especially when it's hot out.

Goes back a lot longer than that, too. A large part of historical African trade was based around salt supplies.

Salt was virtually a currency in Roman times: hence, the word "salary" and how similar the word salt is in various European languages.

Rule of tongue - if it tastes salty its too much salt. Take a half full water bottle. Add some salt. See if it is salty yet, then keep adding until it is just barely salty. Then fill the bottle to the top. If you taste salt you added too much. Note that with kcl, you start with less water, more like a quarter of the bottle, because the salty flavor is much weaker.

This is with every bottle you drink? So basically once I figure out the amount, I should put that much in every time I get a fresh glass?

No, this is only when I am going to exercise for an extended period of time, 30min+. I generally consume enough potassium from fruits and vegetables not to need any additional electrolytes in my day-to-day water.

Basically I don't consume sugar or alt-sugars so I make my own version of gatorade.

Good catch.

These are supposed to be limits not minimum recommendations. Also people get sodium from more than just salt so 5.75g of salt is still high and calling 6g low is kind of a misnomer.
