    > especially relevant in Japan, where the country’s adult population eats more than double the World Health Organization’s recommended intake

    Japan is also the country with the second highest life expectancy in the world. Is salt really that bad? How long would they live if they followed WHO's recommendations?

      No it isn't unless you are salt sensitive. You would know if you are salt sensitive, you would have high blood pressure.

      I'd take some years off my life if it meant I could continue to enjoy salt.
    • hsbauauvhabzb 9 hours ago |
      Iirc only the northern parts of Japan have high salt diets, the south side has lesser intake, but I could be wrong.
      • bamboozled 9 hours ago |
        I don't think this is true at all, everyone here eats a lot of salt.

        Soy sauce is in basically everything, it's full of salt.

      > Is salt really that bad?

      I was wondering, does exercise purge "extra" salt?

      also, since this is japan, would they have a chopsticks model? Maybe this is for soup. Or an export version. Japanese ramen spoons have a different shape.

        When I first heard about that Kirin invention I heard about chopsticks also, so maybe it is in the works

        IIRC sweating is the only way for the body to get rid of salt, so on paper, yes. But it's probably not as simple as that.

          I'm pretty sure you pee it out too.

          No. Absolutely no. The kidneys take care of it pretty good.
      • f1shy 8 hours ago |
        Not really. Of course you tend to drink and sweat more, which contributes.

        No. Your kidneys do this, assuming they work correctly.

      Is salt consumption and life span uniformly distributed across Japan?
      • bamboozled 9 hours ago |
        Everyone in Japan eats a lot of salt, there is no region specific salt intake.

      > Is salt really that bad?

      No, salt is good because it helps you to eat unpalatable, nutritious food.

      • f1shy 8 hours ago |
        And Na is absolutely vital, and depending on your diet, if you cut 100% of table salt you will get deprived of Na and Iodine
    • kopirgan 9 hours ago |
      It's not just one thing. Their diet very low calorie.. Low on fat.

      If we eat oil like Mediterranean fat like Intuit's, carb like Raramurii, protein like Americans will have worst health of all.

      • Blackthorn 4 hours ago |
        Source for the low calorie bit? Seems unlikely, given the amount of rice consumed.
      • wenc 2 hours ago |
        Dietary fat isn't actually bad for you in reasonable amounts. It's the overindulgence of carbs, which turns into body fat.

        Also the Japanese diet is interesting. It's actually not low-calorie pound-per-pound, but the portion sizes are much smaller. The Japanese just eat less than Americans.

        It has also a surprisingly small amount of greens. There is usually a pickled vegetable dish on the side, but that's it.

    • f1shy 8 hours ago |
      Actually a healthy person can regulate Na levels very good. There is a lot of debate if it is as bad as portrayed.
    • kalium-xyz 7 hours ago |
      Im very tempted to think the japanese have higher life expectancy because they are on average much shorter than western europeans with similar quality of life.
      • rafaelmn 4 hours ago |
        You can check this by comparing Japanese who lived in different countries. I vaguely remember it doesn't hold up, but should be simple to search.

      Here's a brief video that makes the claim that you probably need more salt in your diet. He has 3 more salt videos, if you're intrigued.

        This guy is not a healthcare professional and makes intentionally contrarian videos for views. He is cherry picking information and ignoring decades of science on nutritional sodium. Please listen to your doctor, not some random YouTuber trying to monetize your attention.

          As aren't you (and i). And why should i listen to a random Hacker dude? Or a smoking doctor? Dou you think every GP is a nutritionist? And even then...

        • wenc 2 hours ago |
          I watch this guy a lot. I noticed a few things.

          He does two things that increase believability: he cites papers and studies, and he runs experiments on himself. This is good.

          He does one thing that decreases believability: he only cites papers and studies that reinforces his contrarian points, and benignly ignores the rest. This is called being a YouTube influencer.

          In ML terms, his content has high precision and low recall -- he optimizes for true positives but not false negatives. It's a form of confirmation bias. You can still use his data (which I assume to be correctly sourced), but you might want to be skeptical of his conclusions by seeking your own disconfirming evidence.

      tl;dr: Higher (yes, higher) sodium intake correlated with longer life expectancy and lower mortality but the study was observational and not a basis for dietary recommendations.

        Meanwhile the garbage science that got us "salt = blood pressure" has made it into dietary recommendations just fine, ruining food all over the world.

      Salt is not bad for you. The small hypertension decreases people experience on low sodium diets are capped at roughly 10% and salt is almost never the actual cause. It is another victim of choosing a boogie man to hide the fact that sugar is by far the most destructive thing to consume by a huge margin

        • alejoar 9 hours ago |
          A huge percent of the population can't take food with salt because of medical conditions. This would be a quality of life improvement for them.

          You can still eat as much salt as you like, not need to feel pathetic.

          • lm28469 9 hours ago |
            Huge percent you say? Feel free to post a source

            How much of this huge percent are people with bad eating habits and who over used salt for decades in the first place?

            We should stop half assing solutions for symptoms when all we have to do is eat properly in the first place, diet coke doesn't solve diabetes, magic salt simulating spoons don't solve decades of bad choices.

              Being fat is uncomfortable, lowers your life-expectancy and is something many people feel embarrased about. In movies and popular culture fat people are overwhelmingly shown in a negative light (stupid, greedy, impulsive).

              All of which is to say: there are many many negative incentives for people to "eat properly" and obesity is still very common. Telling people to just get more disciplined is obviously not working. (Also, obesity and addiction more generally has a large genetic component, so try to have some empathy)

              • lm28469 8 hours ago |
                > Telling people to just get more disciplined is obviously not working.

                Ok so the solution is to give them a plastic spoon that simulates salt, which solves nothing, gotcha...

                > there are many many negative incentives for people to "eat properly" and obesity is still very common.

                And there are infinitely more incentives for food companies to make you fat and addicted at all cost, and many incentives for the pharmaceutical industry to have fat and unhealthy people they can sell "cures" to.

        • helloplanets 9 hours ago |
          Pretty sure yours is the more common take, rather than the opposite. Or at least a view that is very well represented by just about any news outlet. There's also a popular comedy movie about it.

          So, you're not exactly going against the grain here.

          - landed on the Moon

          - industrialized agriculture to support a population orders of magnitude larger than otherwise possible

          - eliminated smallpox, polio

          - invented penicillin which has saved hundreds of millions

          These are just the ones off the top of my head

      Apparently an unpopular comment but I commend it for having the ability to step back and think "wtf are we doing", which far too many people seem to lack. You've gotta admit that a spoon which adds salt flavour is an oddly superficial use of technology... is it really a good solution to a real problem?

    When I heard about this, I couldn't help but think of the taste of a 9-volt battery on the tongue, but from what I understood/guessed from TFA, this does something more like pulling dissolved sodium ions to the outer surface of the food to make them more readily encountered by taste buds? So, the food would need to have a decent salt content to begin with and not be too dry probably?

      The elephant in the room are electrophoretic effects of metal of the electrode leaching into the food, especially with long-term use.

        For $127 I'm guessing the electrode has some sort of inert coating or plating.

    • LWIRVoltage 9 hours ago |
      It's going to be because it needs a complete circuit. (and firm contact with the handle where there will be another 'electrode'

      This sounds exactly like (for example) electric shock gag pens and other things that attempt to emit a charge - A lot of electrical devices need a complete circuit- and so the circuit needs to be complete. For what this device is doing with moving ions, it probably needs the circuit- I don't know that the few devices out there that emit power without that sort of circuit could accomplish the same.

        Which?
        • cogman10 8 hours ago |
          Primarily seafood.

          You can get it from a lot of other places, but they are unreliable. Plants grown in iodine rich soil will have iodine, but good luck identifying that.

          I use iodized salt because I don't love the alternatives.

        Not really, at least not everywhere. If you live away of sea, you will bot be inclined to eat seafood, also will be expensive. There are many cultures in which the diet does not have enough iodine.
        • ZYbCRq22HbJ2y7 2 hours ago |
          Sure, if you live in a country with submodern infrastructure, doesn't produce enriched wheat, or cannot afford to buy an iodine supplement, you are probably right.

          However 1 cup of milk has more iodine than 1/4 teaspoon of iodized salt, 1 egg has half as much, and two slices of enriched wheat bread has three times as much.

          Also, a typical kelp supplement has way more than the RDV, in a single pill.

    • f1shy 8 hours ago |
      This is a very important point. Also other point is that in some hospitals people are going into ER with hiponatremia. Granted extreme cases. But many people are getting obsessive with low Na. And while a little bit too much will not affect you at all, a little bit too little will affect you immediately.

    But does it work?

    This is the third report I’ve seen in recent days and none of them mention if the spoon delivers on its promise. Reporters may be reluctant to share a spoon with dozens of other attendees, but might they practice some journalism by surveying folks who did try it?

    • kalium-xyz 7 hours ago |
      At that price point placebos become pretty powerful. I’d like to see some actual data of salt distribution with a regular spoon vs theirs.

      EDIT: Seems that it works by stimulating the tongue with current not by changing salt distribution
