I haven't really been paying too much attention to my salt intake in thinking that I know I'm not taking in too much, but after reading that, I might actually be taking in too little.
I've never understood why people think a low- or no-salt diet is beneficial. If our bodies don't get enough salt, WE DIE.
There's a reason salt has been more valuable than gold and jewels throughout human existence; hence a person being 'worth his/her salt'.
Gary Taubes does it again. It's so interesting to learn the history of the health campaigns we're preached to about and about all the dissenting scientific studies that don't get much press. I love that he included quotes about how this information shouldn't be made public.
I have hypertension and I found the article shallow and insulting. So did the following readers:
Overeating salt has very noticeable negative effects on me. It didn't when I was 25 but it does now. Oh, the article left that part out...along with any studies which might call Taube's assertion into question...
I'd have to say that salt depends on a lot on diet. I had horrible problems with swelling whenever I had salt prior to going low carb. Now that I'm low carb, I have to force myself to get enough because I am so used to leaving it out of everything. I think the difference is that having a high insulin level will cause your kidneys to retain salt and generate more uric acid...which can contribute to problems like edema, gout, and hypertension. When carbs are restricted and insulin level drops, the kidneys start excreting more salt and those issues disappear.
Well, one of the major reasons for salt being so valuable in history is that it was the only (poor) iodine supplement for a long time, and many areas of the world were iodine deficient already in the Paleolithic. Another major reason was meat. No refrigeration, it meant all meat had to be cured or eaten right away. Just my grandparents were eating several grams of salt a day from meat alone. But Nature has made sure that we are naturally attracted to salt, sweet, and fat. That is because you need more than in a random natural diet. You have to avoid the pitfalls of artificial, processed sugars and fats, and also learn what is your optimal salt intake.
Let me also mention that people have eaten salted meat for so long that there is certainly a fraction of the population having salt tolerance far in excess of that of primates, just like there are people who can digest grains better.
