Why the War on Salt Is Dangerous

This text was beforehand printed March 15, 2017, and has been up to date with new data.

The speculation that salt is dangerous for you and contributes to hypertension and coronary heart illness is an concept that has turn out to be kind of cemented as dogma. Alas, the battle on salt has had quite a few drawbacks and unintended penalties. For starters, proof exhibits having the proper potassium to sodium steadiness influences your threat for hypertension and coronary heart illness to a far higher extent than excessive sodium alone, and the Western food regimen tends to be missing in potassium.

Furthermore, when decreasing salt in processed meals, many producers took to including monosodium glutamate (MSG) as a substitute — a taste enhancer related to quite a few well being issues, together with weight problems, complications, fatigue and despair. On account of its skill to overexcite neurons, MSG might even elevate your threat for neurological problems similar to Alzheimer’s, Parkinson’s and Lou Gehrig’s illness (ALS).

Battle on Salt Is Misguided

In 2010, New York Metropolis launched the Nationwide Salt Discount Initiative, a salt-reduction plan geared toward decreasing salt in processed meals and restaurant meals by 25% within the subsequent 4 years. Two years later, Dr. Sean Lucan of the Albert Einstein Faculty of Medication wrote an article printed on-line within the American Journal of Public Well being, saying:¹

“We can not extrapolate that decreasing sodium consumption would scale back cardiovascular threat or untimely demise. Regardless of assertions on the contrary, we have no idea that decreasing imply inhabitants sodium consumption would lower the danger of heart problems or save lives.”

On the time, Lucan advised the New York Publish:²

“We will not simply swallow this as reality — there’s really debate about this. My concern is that they are specializing in a single ingredient that the meals trade goes to have to exchange with one thing — and what they change it with may be extra damaging.”

Lucan additionally famous that the connection between sodium and blood stress is inconsistent and from a scientific standpoint, insubstantial. Furthermore, he confused that some research really present a low-salt food regimen can worsen heart problems and lift moderately than decrease the danger for early demise amongst sufferers at excessive threat of coronary heart illness.

As well as, decreasing salt consumption might additionally lower insulin sensitivity and have an antagonistic impact on blood lipids. Appropriately, Lucan famous that “Refined carbohydrates are a higher enemy.”

Potassium Stage Impacts Excessive Blood Strain Extra Than Sodium

Research have clearly proven that having the proper steadiness of potassium to sodium is much extra vital than decreasing salt alone. Potassium is a naturally occurring mineral your physique makes use of as an electrolyte (substance in resolution that conducts electrical energy), and it’s important for optimum well being and regular functioning.

Potassium works in your physique to calm down the partitions of your arteries, preserve your muscle groups from cramping and lowers your blood stress.³ The discount in blood stress with added potassium has additionally been related in research with a diminished threat of stroke.⁴

Whereas diarrhea, vomiting, extreme sweating (similar to when utilizing a sauna) and a few medication might deplete or disrupt your potassium steadiness, the most typical motive for low potassium is consuming a potassium-poor food regimen. When you’re consuming largely processed meals, your sodium-to-potassium steadiness is just about assured to be inversed.

The common reported consumption of potassium from meals is about half of the 4,700 milligrams (mg) really useful.⁵ Analysis demonstrates these low ranges of potassium might have a major impression on blood stress, particularly when mixed with an excessive amount of salt.

Dr. Paul Welton, professor of epidemiology at Tulane Faculty of Public Well being and Tropical Medication, analyzed 29 trials that demonstrated low ranges of potassium resulted in increased systolic blood stress readings.⁶ Research carried out since then have discovered comparable outcomes.^7,8 In accordance with Welton:⁹

“The proof could be very sturdy and really constant. The next potassium consumption might blunt the consequences of extra salt on blood stress. Potassium’s impact is greater in individuals who have increased blood stress, greater in older individuals, greater in people who find themselves consuming numerous salt and larger in black individuals.”

The Many Advantages of Potassium

Current analysis discovered that girls with out hypertension who consumed probably the most potassium (practically 3,200 mg/day) had a 21% diminished threat of stroke. Additional, ladies who consumed probably the most potassium have been 12% much less more likely to die in the course of the examine interval than those that consumed the least.¹⁰

Ample quantities of potassium are additionally related to faster restoration from train and improved muscle energy.^11,12 As an electrolyte, potassium helps to manage the fluid steadiness in your cells and all through your physique.¹³ This fluid steadiness is crucial to sustaining life, stopping dehydration on the mobile stage and sustaining mind perform.¹⁴

For instance, potassium is vital within the transmission of nerve impulses in your mind, spinal wire and peripheral nervous system.¹⁵ Nerve impulses transmitting data from one nerve to the subsequent occurs as the results of electrical exercise. This exercise is what an electrocardiogram measures because it tracks coronary heart exercise.

Low ranges of potassium have additionally been linked with excessive ranges of insulin and glucose,¹⁶ that are related to metabolic syndrome and kind 2 diabetes.¹⁷ These outcomes have been present in a number of research,¹⁸ main researchers to suggest dietary selections that increase potassium ranges and scale back the danger of kind 2 diabetes.

Sodium/Potassium Ratio Is Key to Sturdy Muscle mass

The important thing to enjoyable your arterial partitions and decreasing your blood stress is the sodium-to-potassium ratio. When you eat numerous processed meals and few contemporary greens, there is a good probability your sodium-to-potassium ratio is unbalanced.

When you’re uncertain, use cronometer.com/mercola, a nutrient tracker that means that you can enter the meals you eat after which calculates the ratio robotically. It is usually really useful that you simply eat 5 instances extra potassium than sodium, however most Individuals eat twice as a lot sodium as potassium.

This ratio is much extra vital in your well being than your total salt consumption,¹⁹ and a greater technique to advertise public well being can be to forgo the strict sodium discount component and focus suggestions on a high-quality food regimen wealthy in potassium as a substitute, as this nutrient helps offset the hypertensive results of sodium.

Imbalance on this ratio cannot solely result in hypertension but in addition contribute to quite a few different well being issues, together with:

Kidney stones	Reminiscence decline	Cataracts
Osteoporosis	Erectile dysfunction	Abdomen ulcers
Rheumatoid arthritis	Abdomen most cancers

Much less Salt, Extra MSG

As Lucan suspected, in lots of instances, meals producers did certainly change the salt with one thing extra damaging, specifically MSG. In an effort to normalize this substitution by declaring it protected and wholesome, the Worldwide Glutamate Data Service wrote the article, “MSG Is Helpful in a Decreased Sodium Eating regimen,” saying:²⁰

“Since its discovery over 100 years in the past, [MSG] has been used successfully to boost the umami style in meals. It’s also an efficient technique of decreasing the degrees of salt utilized in meals preparation.

Research have demonstrated that individuals discover meals with low ranges of salt way more acceptable when a small quantity of [MSG] is added. MSG is mistakenly regarded as being excessive in sodium. Nevertheless, MSG accommodates solely one-third the quantity of sodium as desk salt …

MSG is commonly an vital ingredient for individuals on a low-sodium food regimen, as a result of it improves the flavour of a dish whereas decreasing the necessity for salt … [W]hen MSG is added … sodium ranges will be lowered by as much as 40 % whereas sustaining the specified taste.”

Well being Hazards of MSG

Whereas MSG is touted as a protected meals additive, having acquired “Usually Acknowledged as Protected” (GRAS) standing in 1959, scientific proof towards it has stacked up. Mockingly, MSG has even been linked to hypertension,²¹ successfully negating the proposed advantage of changing sodium with MSG. Analysis has additionally linked MSG consumption to:

Endocrine disruption, metabolic syndrome, weight problems22,23 and weight acquire.24 The burden acquire, which was not related to increased quantities of energy, is considered associated to MSG’s impression on leptin. Individuals who ate extra MSG produced increased quantities of leptin, a hormone concerned in urge for food regulation and metabolism. By inflicting leptin resistance, your physique loses its skill to correctly course of the power derived from the meals

Genotoxicity; particularly, MSG was discovered to be genotoxic to human peripheral blood lymphocytes (mature white blood cells/immune cells present in your blood circulation)25

Thyroid harm, even at low doses26

Kidney dysfunction27

Intestinal harm, attributable to progressive harm to epithelial cells in your small gut28

Liver harm that may result in fibrosis, non-alcoholic fatty liver illness and pre-cancerous lesions29,30

Mind lesions,31 seizures and behavioral modifications32

Elevated threat of infertility33,34

Extreme rhinitis in these with MSG intolerance35

Diabetes36

Acute Facet Results of MSG Ingestion

Many additionally expertise extra fast negative effects from MSG, with a pounding headache being some of the distinguished. Whereas the precise explanation for MSG-induced headache stays unclear, analysis investigating the matter has demonstrated that MSG “induces a dose-dependent swelling and demise of mature neurons,”³⁷ which can be a part of the equation. Different frequent negative effects which will happen inside an hour or so of consuming MSG embrace:^38,39

Sweating	Chest tightness	Wheezing and/or issue respiration
Dizziness	Nausea	Diarrhea
Flushing and/or tingling of the face	Burning or numbness at the back of your neck and/or higher physique	Coronary heart palpitations
Stomach ache	Shaking	Weak point within the legs

The MSG Symptom Advanced Is Actual

A double-blind, placebo-controlled, randomized examine⁴⁰ printed in 1997 investigated MSG signs by conducting an oral problem in “self-identified MSG-sensitive topics” to see whether or not they actually had a better incidence of signs after consuming MSG, in comparison with a placebo. Sixty-one individuals acquired 5 grams (gm) of MSG or placebo as an preliminary problem. Of them:

• 29.5% had no response to both MSG or placebo
• 9.8% responded to each
• 24.6% responded to placebo
• 36.1% responded to MSG

Whereas many reported negative effects from the placebo, the severity of signs have been higher amongst those that acquired MSG than placebo. The individuals have been then rechallenged with placebo and 1.25, 2.5 and 5 gm of MSG. In accordance with the authors:

“Rechallenge revealed an obvious threshold dose for reactivity of two.5 gm MSG. Headache, muscle tightness, numbness/tingling, basic weak spot and flushing occurred extra continuously after MSG than placebo ingestion.

Oral problem with MSG reproduced signs in alleged delicate individual … In accordance with Meals and Drug Administration suggestions, the signs, initially known as the Chinese language restaurant syndrome, are higher known as the MSG symptom complicated.”

Vitamin C and Lycopene Provide Safety Towards MSG’s Results

Sure compounds have been discovered to supply some safety towards MSG’s antagonistic results. Vitamin C was discovered to offer “vital safety towards MSG toxicity” in a single examine,⁴¹ and lycopene has additionally been discovered to avert its neurotoxic results. A examine investigating the latter gave male rats both 5 milligrams (mg) per kilo (kg) of MSG, 10 mg/kg of lycopene, MSG with lycopene, or placebo, for 30 days. In accordance with the authors:

“The outcomes confirmed that MSG induced elevation in lipid peroxidation marker and perturbation within the antioxidant homeostasis … Glutathione S-transferase … superoxide dismutase … and catalase … actions and gene expression have been elevated and glutathione content material was diminished within the MSG-challenged rats, and these results have been ameliorated by lycopene …

Our outcomes point out that lycopene seems to be extremely efficient in relieving the poisonous results of MSG by inhibiting lipid peroxidation and inducing modifications within the exercise of cholinesterase and antioxidant pathways. Curiously, lycopene protects mind tissue by inhibiting apoptosis signaling induced by MSG.”

Hidden Sources of MSG

Whereas added MSG should be listed within the listing of components as “monosodium glutamate,” its absence is not any assure of security. MSG and artificial free glutamate in various quantities can nonetheless disguise in processed meals below names similar to:⁴²

Hydrolyzed vegetable protein	Autolyzed or hydrolyzed yeast	Yeast extract
Soy extract	Protein isolate	Pure taste
Glutamate and monopotassium glutamate	Calcium caseinate	Gelatin

Whereas not generally recognized, MSG is even used as a stabilizer in sure vaccines,⁴³ which appears to be a very dangerous concept contemplating its many antagonistic well being results, notably on the mind. In accordance with the U.S. Facilities for Illness Management and Prevention, MSG will be discovered within the following 5 vaccines:⁴⁴

• Adenovirus
• Influenza quadrivalent (FluMist)
• MMRV (ProQuad)
• Varicella (Varivax)
• Zoster (Shingles-Zostavax)

Actual Meals Is the Reply

Getting vitamins out of your meals as a substitute of dietary supplements is preferable as your meals accommodates greater than a single nutrient and in numerous types. As an example, potassium present in fruit and veggies is potassium citrate or potassium malate, whereas dietary supplements are sometimes potassium chloride. The citrate and malate types assist produce alkali, which can promote bone well being⁴⁵ and protect lean muscle mass as you age.⁴⁶

Bone loss might result in brittle bones and even osteoporosis. Whereas potassium in fruit and veggies might assist construct bone well being, potassium chloride might not. As researcher Dr. Bess Dawson-Hughes from Tufts College present in a examine evaluating potassium bicarbonate, sodium bicarbonate and potassium chloride supplementation for 3 months, including alkali, not potassium, is the important thing to enhancing bone well being. She explains:⁴⁷

“In the case of dietary issues relating to bone well being, calcium and vitamin D have acquired probably the most consideration, however there’s growing proof that the acid/base steadiness of the food regimen can be vital …

When fruit and veggies are metabolized, they add bicarbonate, an alkaline compound, to the physique. Our examine discovered that bicarbonate had a positive impact on bone resorption and calcium excretion. This implies that growing the alkali content material of the food regimen might attenuate bone loss in wholesome older adults.”

Analysis by Dawson-Hughes discovered that individuals who have been within the impartial vary for web acid excretion, which means they’d a reasonably wholesome steadiness for bone and muscle well being, have been consuming simply over eight servings of fruit and veggies per day together with 5.5 servings of grains. After they rounded this out, it got here to about half as many grains as fruit and veggies.

For a lot of Individuals, a easy suggestion to extend your alkali (and potassium) whereas decreasing acid is to eat extra greens and fewer grains and processed meals on the whole. When cooking from scratch, you’ve gotten full management over how a lot salt you add.

Along with that, once you do use salt, be sure that its unrefined and minimally processed. My private favourite is Himalayan pink salt, wealthy in naturally-occurring hint minerals wanted for wholesome bones, fluid steadiness and total well being. To be taught extra concerning the significance of unprocessed salt in your food regimen, see the associated articles listed.
