Sodium and well being is a extremely controversial subject currently.
The federal government tells us we shouldn’t be consuming greater than 2300mg a day.
The keto folks inform us that we ought to be supplementing our diets with extra salt.
Influencers are promoting electrolyte dietary supplements with large quantities of sodium in them.
So, who’s proper?
Like something associated to diet, there’s numerous nuance right here. On this put up, I’m going to reply your questions on sodium, and deal with the circumstances in which you’ll want much less, or extra, of it.
What’s sodium?
Sodium is a mineral that our our bodies have to perform usually. It’s not the identical as ‘salt,’ which consists of a sodium ion and a chloride ion (which is why the chemical identify for desk salt is ‘sodium chloride’).
Sodium is of course current in numerous meals, even ones that you simply wouldn’t anticipate like meats, milk, and greens. That is in small quantities although – essentially the most sodium-packed meals are ones which have been ultra-processed or cured utilizing salt.
Sodium has been demonized for many years as the reason for assorted well being points. Whereas it’s true that extreme sodium consumption might be dangerous to well being, we will’t make this a blanket assertion that applies to everybody.
How does sodium work in our our bodies?
We’d like sodium to take care of fluid steadiness, and for conduction of impulses in nerves and muscle tissue. The quantity we’d like for these fundamental features is estimated at round 500mg a day.
That is dependent in your sodium ranges to start with, after all, as a result of there are conditions the place sodium ranges are low and have to be changed.
Sodium ranges can go low if you lose fluids via weight loss program (extra on that in a bit), sweat, poop, pee, or vomit, or if in case you have elevated fluid losses from, say, an ileostomy or diuretics.
They’re additionally affected if in case you have a situation that causes fluid retention and dilution of sodium within the physique – resembling coronary heart failure or kidney illness. In these instances, including extra sodium to your weight loss program might be detrimental to well being, so we deal with the reason for the dilution to deliver sodium ranges again to regular that means.
The kidneys are at all times working to take care of the sodium steadiness in our our bodies.
Let’s say you ran for 3 hours in 100F warmth, and also you misplaced numerous fluid. Your blood stress would lower, which might then ship hormonal indicators to the kidneys to filter out potassium, and retain sodium and fluid within the physique to deliver the blood stress again up.
All of those features are regulated by hormones referred to as aldosterone and antidiuretic hormone (ADH), amongst others.
Once we devour extra sodium, our blood sodium rises, and our kidneys maintain on to fluid to dilute the sodium in our blood.
Ultimately, the kidneys do away with that extra sodium and fluid in urine.
Issues turn into problematic when somebody eats extreme sodium all through the day, on daily basis. That’s as a result of the kidneys get strained and overwhelmed, and may’t handle the surplus sodium within the blood, resulting in extra persistent fluid retention, which places stress on blood vessels, resulting in elevated stress – aka ‘blood stress.’
Hypertension causes harm to blood vessels, resulting in kidney harm and a threat of coronary heart assault, stroke, aneurysm, imaginative and prescient loss, abdomen most cancers, and even reminiscence points, amongst different issues.
This all sounds scary, however most of us don’t need to micromanage our sodium consumption.
What are the suggestions round sodium?
The typical North American consumes round 3400 mg of sodium a day, which is lots larger than the advisable 2300 mg.
Youngsters and infants want between 1200-1800 mg/day.
The vast majority of our sodium comes from extremely processed and ready meals, not from the salt shaker in our kitchens.
The best sodium degree for you might be controversial. Some research have prompt that low ranges of sodium within the weight loss program (underneath 2300 mg/day) don’t influence coronary heart illness threat for folks with hypertension. There are lots of people on-line who’re saying that sodium doesn’t have an effect on our well being in any respect, and I’ll deal with that in a bit.
All in all, essentially the most sensible method to handle sodium is to attempt to restrict your consumption of ultra-processed meals as a lot as you may.
In case your blood stress is regular, and also you’re consuming a weight loss program that’s largely complete and minimally processed meals, you in all probability don’t need to be involved with the quantity of sodium you’re consuming.
Exterior of particular diagnoses, some individuals are extra delicate to salt than others. This appears to be due to an irregular response by the kidneys to sodium, however there isn’t a widespread diagnostic check for salt sensitivity.
As with every part, it’s a steadiness. Some belongings you eat are going to be excessive in sodium, as a result of CHIPS. That’s completely positive for many of us – the physique can deal with the occasional inflow of excessive sodium meals.
While you’re a diet label, you’ll need to take a look at the p.c every day worth of sodium that the meals incorporates. If it has greater than 15%, meaning it’s a excessive sodium selection.
In case you’ve had a coronary heart assault, comply with the recommendation of your physician and RD by way of how a lot dietary sodium they suggest. If the center has sustained harm, or you might have coronary heart failure, they’ll in all probability suggest a decrease sodium weight loss program to assist keep away from additional harm to the center and vessels.

Sodium and keto
Lots of people who’re on low-carb and keto diets take electrolyte dietary supplements, and there are a number of explanation why they might really need extra sodium. First, the shortage of ultra-processed meals of their diets imply that they might be consuming much less sodium than the typical individual.
Second, insulin has been proven to trigger reabsorption of sodium into the system as a substitute of elimination via the urine. If somebody’s insulin ranges are low (and they are often with a weight loss program that incorporates only a few carbs), they will not be holding on to sodium – and an electrolyte complement may help with that. Some suggestions for sodium on a keto weight loss program can vary from 3000-5000+ mg/day.
The preliminary fluid loss that individuals expertise from not consuming carbs can be dehydrating and result in elevated sodium wants.
How a lot water do we’d like in a day? Listed below are the suggestions.
For this reason you’re seeing numerous influencers promoting electrolyte replacements (I’m not naming any right here) and ingesting large cups of water with Himalayan salt.
Evidently, in the event you’re not on a low-carb or keto weight loss program, you’re in all probability positive with out the electrolyte dietary supplements or salty water. The folks saying that everybody wants an electrolyte complement, are unsuitable (they usually’re in all probability making an attempt to promote you one thing).
The DASH Weight-reduction plan
The DASH Weight-reduction plan – Dietary Approaches to Cease Hypertension – has been round for many years. Based mostly on the DASH examine from 1997, it reads like one thing that hasn’t been up to date….since 1997.
That was earlier than even I acquired my diet diploma.
The weight loss program has two ranges of every day sodium – 2300mg, and 1500mg which, as a dietitian, I’ll let you know is extraordinarily onerous to take care of for most individuals consuming a diversified weight loss program.
My points with DASH are many.
The weight loss program recommends low-fat and fat-free meals like salad dressings (nonetheless salty) and dairy.
It limits nuts and seeds to 4-5 servings per week, and meat/fish servings to 6oz a day. Whole.
The grain suggestion is, for my part, means too excessive (for carbs and for salt) at 7-8 servings a day.
Fruit servings are too excessive (4-5 a day) and vegetable servings are too low (4-5 a day).
The weight loss program nonetheless maintains that dietary ldl cholesterol ought to be restricted. This has been debunked many instances, notably right here. It additionally promotes a low-fat consuming sample, which, ignoring present analysis, appears to restrict even wholesome fat, and doesn’t make the excellence between dairy and meat fat. (right here) (right here)
I’ve by no means advisable the DASH Weight-reduction plan to anybody for these causes.
sodium and train
Athletes, individuals who sweat lots and/or work out strenuously at size (greater than 60-90 minutes) in scorching climate, might have extra sodium to switch what they’ve misplaced. Not changing sodium may end up in hyponatremia, which is dangerously a low sodium degree. If this isn’t your scenario, and also you’re consuming regularly, you’re in all probability positive with plain water.
This piece from ACE has some good tips and charts round changing electrolytes throughout and after train.
What’s POTS? (Postural Orthostatic Tachycardia Syndrome)
POTS causes dizziness and quick coronary heart fee if you go from sitting or mendacity down, to standing. Mainly, your physique can’t stabilize blood stress, main to those and different signs.
POTS is a really actual factor and it’s additionally fairly widespread. Though we don’t know what the precise reason for POTS is, it appears to be related to viral sicknesses, being pregnant (POTS is way extra widespread in females than males), head trauma, and surgical procedure. Folks with autoimmune ailments are additionally extra more likely to develop POTS.
There are three sorts of POTS: hypovolemic, hyperadrenergic, and neuropathic. For individuals who have hypovolemic POTS, low blood quantity causes signs. A weight loss program with ample fluids and as much as 10,000 mg of sodium a day (sure, that’s lots) may help enhance blood quantity and alleviate signs. On this case, electrolyte dietary supplements may help.
Meals which might be excessive in sodium
You possibly can in all probability guessed that meals that style salty – like chips, pickles, quick meals, and frozen meals – are excessive in sodium. I’ve discovered that just about something from a restaurant is excessive in sodium, just because they add numerous salt. Salt makes issues style good!
Hidden sources of sodium embody cottage and common cheeses, breads and pastries, soy and different sauces, sauerkraut (even when it’s good on your intestine, it’s nonetheless salty), and salad dressings. Canned meals can be excessive in sodium, so in the event you’re watching your salt consumption, select low-sodium varieties.
Sodium myths
Fantasy: Sodium isn’t dangerous for us; it’s the components in packaged meals that trigger coronary heart illness
I’m not into conspiracy theories, however you’ll discover numerous them surrounding sodium (particularly on a sure fashionable electrolyte firm CEO’s social feed…simply wow)
A weight loss program that’s excessive in sodium, whether or not from packaged meals or not, has proven to be deleterious to our well being (right here) (right here) (right here). The sugar and lack of fibre in packaged meals are one thing totally different, however are additionally related to threat for illness.
None of this issues all that a lot in the event you’re consuming a weight loss program that’s pretty low in ultra-processed and packaged meals.
I’m unsure why anybody would even need to problem the considering that extra sodium is dangerous to us – a decrease sodium weight loss program is one thing that goes hand in hand with consuming extra complete meals. Looks as if a bizarre factor to dispute.
Fantasy: Himalayan pink salt, kosher salt, and Celtic salt are more healthy than desk salt
Nope. Salt is salt, irrespective of how fairly it’s, or if somebody hand-picked it from essentially the most distant place on the planet.
And Redmond Actual Salt? It’s salt. All salt is actual, please don’t fall for these ridiculous advertising and marketing ploys.
Sure, some salts have hint quantities of minerals in them. Nonetheless, you’d need to eat numerous salt to get any considerable results from these. Don’t eat salt for the iron.
Bobby Parrish of FlavCity has been identified to assert that Himalayan salt doesn’t influence blood stress like different salts, and he’s unsuitable (what a shock). All salt is sodium chloride. The chloride doesn’t have a lot impact on blood stress, however the sodium nonetheless does. So far as quantities of sodium in pink or kosher salt versus desk salt, they’re across the similar by weight.
A teaspoon of any rock salt might appear to have much less sodium than the identical quantity of desk salt, however that’s as a result of extra desk salt matches onto a teaspoon. That’s all.
A lot of the unrefined salts on the market aren’t iodized, which might be a problem for somebody who isn’t getting sufficient iodine of their weight loss program.
In a latest Reel, I referred to as out an influencer for suggesting that desk salt is bleached. It’s not. Sodium chloride is WHITE.
See my Reels for particulars, and please don’t comply with folks like this.
It’s an enormous pink flag when anybody claims that desk salt is much less ‘wholesome’ than different salts.
Fantasy: Salt helps you soak up water, so it’s best to drink salt water within the morning to assist hydrate you all day lengthy
The ‘salt makes water wetter’ speculation. I hear numerous health trainers saying this.
It’s an ideal instance of why many health trainers shouldn’t be giving diet recommendation.
Whereas we do want sodium and different electrolytes to soak up water, most of us devour greater than sufficient via meals. We solely want round 500mg a day for our bodily features, so that you don’t want so as to add salt to your morning water. Even in the event you do, it gained’t assist hydrate you all day, as a result of your kidneys will flush it out fairly shortly.
Please don’t pile extra salt onto a weight loss program that’s in all probability greater than ample in sodium. And most of us undoubtedly don’t have to salt our fruit for ‘hydration’:
Lengthy story brief: in the event you’re consuming and also you aren’t shedding a ton of fluids (we talked about this above), you don’t want salt for hydration.
The underside line on sodium is that this: most of us eat greater than sufficient of it. In case you eat a weight loss program excessive in complete meals, and also you don’t have any present well being points, you in all probability don’t have to micromanage your sodium consumption.
