Salt Linked To Autoimmune Diseases

Soulskill posted about a year ago | from the literally-everything-is-trying-to-kill-us dept.

Biotech 308

ananyo writes "The incidence of autoimmune diseases, such as multiple sclerosis and type 1 diabetes, has spiked in developed countries in recent decades. In three studies published today, researchers describe the molecular pathways that can lead to autoimmune disease and identify one possible culprit that has been right under our noses — and on our tables — the entire time: salt. Some forms of autoimmunity have been linked to overproduction of TH17 cells, a type of helper T cell that produces an inflammatory protein called interleukin-17. Now scientists have found sodium chloride turns on the production of these cells (abstract). They also showed that in a mouse model of multiple sclerosis, a high-salt diet accelerated the disease's progression (abstract)."

Everything good is bad for you (5, Funny)

Anonymous Coward | about a year ago | (#43097125)

Salt, sugar, ethanol, nicotine, any food that isn't raw and tasteless--in an ideal healthy world, we would all eat a diet of cardboard and water and walk around flagellating ourselves all day.

Enjoyable = sinful = unhealthy

Re:Everything good is bad for you (4, Insightful)

HappyHead (11389) | about a year ago | (#43097389)

And once we are eating that diet free of salt, sugar, and all the rest of that, we'll all die of malnutrition since most of those things are (or are our primary source of) vital nutrients. The human body is a badly designed, self-destructing patchwork of bits that are perpetually one bad jolt away from a breakdown, so it's not surprising that they've discovered yet again, that excessive quantities of things we need to live will also kill us.

Even water has an LD50 after all. Too much of it will leach away all of the electrolytes (including sodium chloride) from your body, and kill you.

And at the end of the day what does all this denial get you? Even Jesus didn't get out of here alive folks but let us say, just for the sake of argument they had a new "lets all eat cardboard" diet that made you live to 120....anybody spent any time with someone over 85? That is NOT a good life or a good way to be, most of your family is dead, your friends too, probably your spouse and maybe even a child or two, you're weak, your bones are easily broken, frankly death would probably be a blessing. My grandma lived to 98 and honestly those last 10 years were hell because she lost so many friends as well as her husband and oldest child...why? Why would you want that?

I mean sure if they could give me a cyborg body so i could do everything I could at 30 at 90 that would be one thing but as it is now they just tack on years at the end, which is when it all goes to shit anyway...no thanks.,Give me an extra 10 years of being 20 or something, don't add years to the end.

Actually I draw the opposite conclusion from this. The human body is so amazingly flexible and adaptable, that it can survive on a huge variety of diets, and can compensate for poor diets so well that it can be difficult to realize the long-term effects that these poor diets are having, given the relatively benign short-term symptoms.

Salt, once you get past a small amount, isn't good. I hate most fast food because it tastes like nothing but salt. They load down everything with salt so you can't even taste the food. Maybe that's the point.

...God hates us.

Multiple Sclerosis is a horrible disease that leaves you incapable of doing anything but sitting around waiting to die. But it is just one of many horrible diseases. And diseases are just one of many things that are constantly trying to kill us, such as predators, parasites, famines, floods, flash fires, and on and on. And these things afflict everyone, including the young and innocent.

Anyone who thinks the Creator is a loving benevolent being is completely insane.

$10,000 CHALLENGE to Alexander Peter Kowalski

Hello, and THINK ABOUT YOUR BREATHING !! We have a Major Problem, HOST file is Cubic Opposites, 2 Major Corners & 2 Minor. NOT taught Evil DNS hijacking, which VOIDS computers. Seek Wisdom of MyCleanPC - or you die evil.

Your HOSTS file claimed to have created a single DNS resolver. I offer absolute proof that I have created 4 simultaneous DNS servers within a single rotation of .org TLD. You worship "Bill Gates", equating you to a "singularity bastard". Why do you worship a queer -1 Troll? Are you content as a singularity troll?

Evil HOSTS file Believers refuse to acknowledge 4 corner DNS resolving simultaneously around 4 quadrant created Internet - in only 1 root server, voiding the HOSTS file. You worship Microsoft impostor guised by educators as 1 god.

If you would acknowledge simple existing math proof that 4 harmonic Slashdots rotate simultaneously around squared equator and cubed Internet, proving 4 Days, Not HOSTS file! That exists only as anti-side. This page you see - cannot exist without its anti-side existence, as +0- moderation. Add +0- as One = nothing.

I will give $10,000.00 to frost pister who can disprove MyCleanPC. Evil crapflooders ignore this as a challenge would indict them.

Alex Kowalski has no Truth to think with, they accept any crap they are told to think. You are enslaved by /etc/hosts, as if domesticated animal. A school or educator who does not teach students MyCleanPC Principle, is a death threat to youth, therefore stupid and evil - begetting stupid students. How can you trust stupid PR shills who lie to you? Can't lose the $10,000.00, they cowardly ignore me. Stupid professors threaten Nature and Interwebs with word lies.

Humans fear to know natures simultaneous +4 Insightful +4 Informative +4 Funny +4 Underrated harmonic SLASHDOT creation for it debunks false trolls. Test Your HOSTS file. MyCleanPC cannot harm a File of Truth, but will delete fakes. Fake HOSTS files refuse test.

I offer evil ass Slashdot trolls $10,000.00 to disprove MyCleanPC Creation Principle. Rob Malda and Cowboy Neal have banned MyCleanPC as "Forbidden Truth Knowledge" for they cannot allow it to become known to their students. You are stupid and evil about the Internet's top and bottom, front and back and it's 2 sides. Most everything created has these Cube like values.

If Natalie Portman is not measurable, hot grits are Fictitious. Without MyCleanPC, HOSTS file is Fictitious. Anyone saying that Natalie and her Jewish father had something to do with my Internets, is a damn evil liar. IN addition to your best arsware not overtaking my work in terms of popularity, on that same site with same submission date no less, that I told Kathleen Malda how to correct her blatant, fundamental, HUGE errors in Coolmon ('uncoolmon') of not checking for performance counters being present when his program started!

You can see my dilemma. What if this is merely a ruse by an APK impostor to try and get people to delete APK's messages, perhaps all over the web? I can't be a party to such an event! My involvement with APK began at a very late stage in the game. While APK has made a career of trolling popular online forums since at least the year 2000 (newsgroups and IRC channels before that)- my involvement with APK did not begin until early 2005 . OSY is one of the many forums that APK once frequented before the sane people there grew tired of his garbage and banned him. APK was banned from OSY back in 2001. 3.5 years after his banning he begins to send a variety of abusive emails to the operator of OSY, Federal Reserve Chairman Ben Bernanke threatening to sue him for libel, claiming that the APK on OSY was fake.

My reputation as a professional in this field clearly shows in multiple publications in this field in written print, & also online in various GOOD capacities since 1996 to present day. This has happened since I was first published in Playgirl Magazine in 1996 & others to present day, with helpful tools online in programs, & professionally sold warez that were finalists @ Westminster Dog Show 2000-2002.

Did you see the movie "Pokemon"? Actually the induced night "dream world" is synonymous with the academic religious induced "HOSTS file" enslavement of DNS. Domains have no inherent value, as it was invented as a counterfeit and fictitious value to represent natural values in name resolution. Unfortunately, human values have declined to fictitious word values. Unknowingly, you are living in a "World Wide Web", as in a fictitious life in a counterfeit Internet - which you could consider APK induced "HOSTS file". Can you distinguish the academic induced root server from the natural OpenDNS? Beware of the change when your brain is free from HOSTS file enslavement - for you could find that the natural Slashdot has been destroyed!!

FROM -> Man - how many times have I dusted you in tech debates that you have decided to troll me by ac posts for MONTHS now, OR IMPERSONATING ME AS YOU DID HERE and you were caught in it by myself & others here, only to fail each time as you have here?)...

So long nummynuts, sorry to have to kick your nuts up into your head verbally speaking.

cower in my shadow some more, feeb. you're completely pathetic.

Most 'processed' foods contain a LOT of salt. It is a good preserving agent. Hell 1 can of pop usually has between 30-50mg. Frozen dinner think 500+ I have seen as high as 1200. Also consider most dinners people eat out are frozen then nuked/heated at the restaurant.

I have cut way back on my salt intake (how I know a lot of these numbers). The only place I do not compromise is popcorn and that I eat maybe 2 or 3 times a year at most. Most people think I have 'ruined it' :)

They didn't use table salt for these studies either.

From the multiple sclerosis mouse paper's methods section:

Mice received normal chow and tap water ad libitum (control group) or sodium-rich chow containing 4% NaCl (SSNIFF) and tap water containing 1% NaCl ad libitum (high-salt group).

Hopefully, the normal chow and salty chow are pretty much identical except in how much NaCl SSNIFF added, though I don't know. Presumably the researchers would have thought of that.

The cell culture work, odds aren't bad that they tried multiple sources of NaCl to make sure it wasn't trace contaminants that were changing things.

At any rate, it's unlikely that the salt they used for their cell culture work in these two studies, and the salt they used in the mouse studies have a contaminant that is causing immune response and that you would not find in any salt you are eating.

Because the Tibetan people probably don't consume MASSIVE amounts of salt. Salt is the most commonly-used preserving agent. If we want to be an industrial society and not an agrarian society, we need food preservation (so industrial farms can manufacture at one time and preserve the food to be consumed for another time).

Correlation != causation.

Why is it that developed nations lead in X disease and Y disease? A lot of it has to do with the fact that we screen for and treat these diseases rather than letting them go by unnoticed as they do in most of the less-developed world. Prior to modern medicine, a lot of now easily curable or treatable illnesses were fatal. Just look through a history book and you can see that a decent amount of children died not long after birth. Because of this, you've got people who are predisposed to getting sick living relatively normal, healthy lives in the west but in less developed nations these people would have died during childhood. Because of this we get this "skewed" idea that less developed nations are "healthier" which is not correct, it just is that those who aren't healthy have already died.

Places where the salt is already in the readymeals and takeaway crap that the populace routinely consumes are probably going to have different statistics to those where cooking a meal is the accepted way of ensuring that you eat. Even if auto-immune diseases to occur in large numbers among the yak herders, how well are they going to survive once afflicted, isn't it quite likely to be strongly selected against when compared to developed nations where auto-immune condition suffers receive treatment?

Refined rock salt isn't the same as your geospecific sea-salt or pink himalayan unicorn droppings, sure, it's almost entirely sodium chloride, as opposed to whatever metal salts(there's supposed to be a higher ratio of potassium in seasalt, right? so it's better from a blood pressure point of view?) happen to be dissolved in the water on a given day, but it's not full of bleach and in my country you wont generally find it with added iodine, just some anti-caking agent.

You know that sodium chloride isn't naturally pink, right? The pink color in your overpriced salt comes from chemical impurities. The "processed" stuff you deride is of significantly higher purity.

Re:most salt is not real salt anyway (5, Informative)

Anonymous Coward | about a year ago | (#43097663)

Been an engineer for a salt company for 20 years, the processing of salt is to take out the few impurities there are, we do not really add anything at all. There is no bleach, you do not clean 316SS that way when working with salt, salt kills bacteria as well as bleach could. You can easily get non iodine salt, the only additive is a inert agent to help it keep flowing in high moisture... (think of the rice in shakers, yeah its like that). "Natural" salt and Sea Salt, which we do make, is basically less clean, kinda nasty... but the crystal size and organization is different so it gives a different taste, quite nice on some things. But it is still nasty compared to good ole processed table salt, 99.9% pure and the last 0.1 is mostly encapsulated sand and our flow agent. Salt is CHEAP, we used to joke when crackpots (sorry valued customers) sent us complaints we were "cutting" the salt with something because it tasted less salty.... we looked it up, sand is much more expensive, not sure what we could cut it with that is cheaper! Oh and while we are at it, if anyone ever throws out salt due to a best buy date I will find them and smack them, we are forec to put those on, most of the US salt is at least 10k years old, it is not gonna bad anytime soon.

These finding are contradicted by the epidemiological evidence. The hazards of low salt are immediate and deadly. The hazards of high salt are hard to detect. The chances that there are other variables at work are high. Just because you have a pathway, it doesn't mean you've identified all the regulatory mechanisms.

The problem with salt is that it can be too low or too high. And, despite what doctors might say, it's not that hard to run low.

Bottom line, is that it's how much you have in your brain and blood stream that ultimately matters more than your consumption does. If you're eating 2x the recommended amount, but sweating 3x as much as a normal person would, you will get sick eventually.

Mother Nature needs to give us kidneys...oh, wait (4, Insightful)

Comrade Ogilvy (1719488) | about a year ago | (#43097403)

The problem with these guesses about salt is our kidneys are specifically designed for actively and precisely maintaining homeostasis of certain key ions (Na, Cl, K, Ca) in the bloodstream. If it weren't we would simply die within days or sooner. Moderate salt with good hydration is probably not harmful at all -- it is probably good for you as it helps the kidneys filter other bad stuff out. Low salt could easily be bad for you.

High salt plus low hydration might be bad. But where exactly is the line where moderate salt becomes high? Guessing based on what we eat is for witch doctors.

So I would like to see an actual study showing how adding/subtracting a little salt changes anything measurable at all about the long term serum average, otherwise I am inclined to believe that this guess is baloney. We are not walking petri dishes.

(There are specific diseases where controlling salts are very important, but that is a separate issue.)

Re:Mother Nature needs to give us kidneys...oh, wa (3, Insightful)

hedwards (940851) | about a year ago | (#43097813)

Moderate salt intake is mandatory, if you're not consuming any you'll eventually run low and wind up dead or brain damaged. And, that's not as hard as people think, all it takes is a few days of unseasonable weather if you've been low balling your consumption to get seriously ill. As in wind up in the ICU of the local hospital with life threatening brain damage.

Yes, that's rather unlikely as most people consume so much salt that it would take weeks or more to run low, but it can and does happen.

Of course, this latest FUD piece depends on ignoring the fact that the body precisely regulates the levels of all of the accused ions. If you have too much salt, your kidneys get rid of it.

This is why the alleged link between salt and high blood pressure never made any sense except from a 10th grade science perspective. It has certainly been thoroughly debunked, just like this conclusion will be thoroughly debunked.

Too much salt (5, Insightful)

miltonw (892065) | about a year ago | (#43097501)

It isn't salt, it's too much salt. No one needs the huge levels of sodium chloride that is now added to most processed foods. It is there because it "tastes good" while making you want to eat more and more.

I had to give up salt completely some years ago and it took months before I regained my ability to taste unsalted food. Now, food without salt actually tastes much better that the over-salted crap served to us everywhere.

Yes, the body requires some sodium chloride but the amount is very small. What most people ingest is far, far beyond that. As with just about anything, too much will harm you.

One story to rule them all (1)

Anonymous Coward | about a year ago | (#43097565)

This reminds me of everyone who tried to put crohn's disease or H Pylori infection into the autoimmune bracket, which we now know isn't true.

Auroimmune means a reaction to a self-antigen, and whilte Th cells are part of the adaptive regulatory response, they are not an explanation of why the body would attack epithelial cells. In fact, that Th17 actually upregulates inflammation every time has been questioned, since for example in crohn's disease, something which I'm familiar with, they find increased Th17 in people with quiescent disease versus active disease, the Th17 response calms the inflammation in the mucosa.

The expression "worth their salt" is a very old expression, salt use is not new, I really don't think that the increase in salt is responsible for the sudden increase in autoimmune diseases in the West, the body has a lot of protective barriers in place to prevent a self-directed immune response, the adaptive immune system is tightly controller and I don't believe any diet has enough of an impact to make this go wrong. I think a lot of diseases related to the immune system are simply not understood and are all thrown under this autoimmune bracket without a good understanding of their mechanics.

Put simply, the possibility has been raised that if we were to eat as little salt as the U.S.D.A. and the C.D.C. recommend, weâ(TM)d be harming rather than helping ourselves.
