    Please excuse my not understanding this but are the studies saying salt isnt good or too much too little isn't good. Can you explain this in layman terms. also what is urea. Thank you.

    I posted that quote in reply to the note that the email-wiki was not available at that time. I have not really read the studies.

    Only screened the first one: It says that aldosterone and insulin went down with higher salt intakes. Norepinephrine (noradrenalin) increased with sodium infusion, but decreased on a high-salt diet.

    Free fatty acids were on average higher with high sodium intakes, but they said this was 'not all statistically significant'.
    Lowered aldosterone is a good thing. Increased FFA is not desirable. Both high aldosterone and high FFA impair glucose handling. For me the question is, why did sodium increase FFA in some participants and not in others?

    The authors discussed this question, but did not really come up with a definite answer. If I should guess, I would say that ones with increased FFA had lower liver glycogen stores (blood samples were taken in overnight fasted subject, even saline infusion was given to fasted subjects).

    Urea is formed in the body, for example to detoxify ammonia.

    oooooh okay.. got it. Thank you very much. I guess just go by what your body is craving IMO. Don,t overdue salt but make sure you have enough..hmmm. I think you said that somewhere.

    Because the extra salt increased metabolic requirements as the study itself said. The people on high salt diet were always hungry. So, even with good glycogen stores you can get into a fuel deficiency state depending on just how much salt revved up metabolism. Thyroid can do the same, as we all know, when consumed on empty stomach or by a malnourished person.

    That sounds like if you are obviously hungry and continue to eat while glycogen stores are good that would have you burn muscle and put on weight? Just how my non scientific mind is thinking. Lol

    No, because the extra energy you consumes will go into synthesizing urea.

    That's what the whole study was about - extra salt increases urea synthesis, which is an energetically demanding process, hence the increase in caloric demands. It's even in the title.

    I see it said that but didn't understand what it all ment. I wasn't sure if it was a good or bad thing. Giraffe explained it to some degree and you finished it. It was just very scientific reading.
    like what Giraffe explained above. I wasn't sure what ffa and aldosterone, and if the effects were good or bad. Also he explained urea which I still reading about. I thank you both for your patience of explanation.

    will supplementing orally with urea decrease metabolism since the body doesn't have to expend the energy to produce it? what effect will urea supplement have on body temperature? will it increase body temp if the temp was a little low?

    Herb Doctors: Continuing Research On Urea

    On urea, but you would expect the same therapeutic effect from more salt:
    "[..]And to keep [the cell] towards the slightly acidic, metabolizing state, in which it doesn’t tend to proliferate; a relatively slightly dehydrating effect."

    But once they're too de-energized, extra salt can be harmful:
    "If the cell is disturbed, then it shifts and loses potassium and takes up calcium and sodium. This is what Gilbert Ling has devoted his life to for the last 60 some years."

    I believe the amounts of salt that optimize health are a bit higher for humans in relation to other animals because we're under chronic stress. No other animal has to endure the task of comprehending Travis' posts.

    This has been my experience when I took 2 Tb+ of salt.

    This illustrates the anti-cancer effects of urea, which robs tumor areas of their water, which Gar Hildenbrand explained is what paralyses normal metabolism around tumors, and which the Gerson people resolve by restricting salt

    I think this matches well with the overall observation from Ling, Warburg, Pauling, Peat, etc that cells start to proliferate when they take up water. So, as per Peat's quote, keeping organism in a slightly dehydrated state should be potently anti-proliferative. In my experience, extra sugar causes this dehydration quite easily confirmed by strongly increased thirst in doses of 40g-50g or more per sitting.

    @haidut between burtlancast's comments on salt and tumor growth and your quote above, I'm now a little weary about my salt intake. I've searched to see if Dr. Peat has followed up on these discussions about the possible negatives of salt intake, but haven't found anything. I'm consuming 10 grams of salt daily due to Dr. Peats recommendations - am I potentially harming myself? Any expert advice would be appreciated?

    I was really excited about increasing my salt intake, too, as Dr. Peat seemed so sure about it!

    I don't think 10g is that much. Up until the early 1960s the average salt intake for an adult in the US was about 12g-15g daily. These days, with everything being made "low sodium" by default, those 10g probably bring you closer to normality and not anywhere in danger-zone. But I think salt should be eaten to taste, not so much based on set daily goals.

    Should not high salt intake be a good treatment for gout? And the gout epidemic a result of salt restriction while still having high protein intake?
