How does SALT raise Blood Pressure?

Research suggests that salt-rich diets significantly increase blood pressure and that lowering the salt content of a persons diet can help lower their blood pressure levels .

For instance, two large reviews report that a reduction in salt intake of 4.4 grams per day may lower systolic and diastolic blood pressure by up to 4.18 mm Hg and 2.06 mm Hg respectively (

12 ).

A review including more than 268,000 participants suggests that those with median salt intakes of 3 grams per day may have up to a 68% higher risk of stomach cancer than those with median salt intakes of 1 gram per day .

Another study further suggests that people with high salt intakes may have a two times higher risk of stomach cancer than those with lower intakes. Still, this study doesnt clearly define what is considered high or low salt intake .

The mechanism behind salts effect on stomach cancer isnt fully understood. However, experts believe that salt-rich diets may make a person more vulnerable to stomach cancer by causing ulcers or inflammation of the stomach lining (

16 ).

While its possible that eating too much salt doesnt increase the risk of heart disease or premature death for everyone, more studies are needed before strong conclusions can be made.


Eating too much salt in the long term may raise your blood pressure and increase your risk of stomach cancer. It may also increase the risk of heart disease and premature death, although more research is needed to confirm this.

Signs Of Deficiency And Toxicity


A deficiency of sodium in the U.S. is rare because it is so commonly added to a wide variety of foods and occurs naturally in some foods. Hyponatremia is the term used to describe abnormally low amounts of sodium in the blood. This occurs mainly in older adults, particularly those living in long-term care facilities or hospitals who take medications or have health conditions that deplete the body of sodium, leading to hyponatremia. Excess vomiting, diarrhea, and sweating can also cause hyponatremia if salt is lost in these fluids that are expelled from the body. Sometimes too much fluid abnormally collecting in the body can lead to hyponatremia, which might stem from diseases such as heart failure or liver cirrhosis. In rare cases, simply drinking too much fluid can lead to hyponatremia if the kidneys cant excrete the excess water. Symptoms of hyponatremia can include: nausea, vomiting, headaches, altered mental state/confusion, lethargy, seizures, coma.

Are There Other Ways To Reduce Blood Pressure

  • Cutting down on the amount of salt we eat helps reduce blood pressure. But our whole diet is also important, as is being a healthy body weight, and if drinking alcohol doing so in moderation.
  • An example of a dietary pattern shown to improve blood pressure is the DASH diet. It emphasises a good intake of fruit and vegetables, low fat milk and milk products , choosing wholegrain foods, poultry, fish and nuts and eating less fats, red meat, sweets and sugary drinks. The DASH diet has a higher intake of potassium, calcium, magnesium and fibre. Saturated fat intake is lower than the typical Western diet, and protein intake is higher.

Our ‘Salt and the heart’ evidence paper recommends we continue to reduce dietary salt intakes, you can read more about our recommendations around salt and the heart in our Sodium Position Statement .

How Can I Check My Blood Pressure

High Blood Pressure Nutrition

High blood pressure is one of the most important health conditions to check for. Its common and can cause serious health problems. Its essential to monitor your blood pressure regularly so you can be sure to take action if necessary. There are two different types of high blood pressure. These are hypertension and isolated systolic hypertension. Hypertension occurs when the blood pressure is high and cannot be attributed to other factors. Some of these factors include being overweight, having diabetes, or taking certain types of medication. Isolated systolic hypertension is high blood pressure that doesnt seem to be caused by anything other than your blood pressure. While it cant be diagnosed until it occurs, its an important condition to be aware of, since it can progress into a more serious condition. Additionally, your blood pressure can be tracked using a blood pressure cuff. These are usually placed around your arm, usually around the wrist or the upper arm. These are usually equipped with a gauge that will tell you your blood pressure.

    Misperceptions About Salt Reduction

    • On a hot and humid day when you sweat, you need more salt in the diet: There is little salt lost through sweat so there is no need for extra salt even on a hot and humid day, although it is important to drink a lot of water.
    • Sea salt is not better than manufactured salt simply because it is natural. Regardless of the source of salt, it is the sodium in salt that causes bad health outcomes.
    • Salt added during cooking is not the main source of salt intake. In many countries, about 80% of salt in the diet comes from processed foods.
    • Food does not need salt to have appealing flavour. It takes some time for a persons taste buds to adjust, but once they get used to less salt, one is more likely to enjoy food and notice a broader range of flavours.
    • Food has no flavour without salt. Whilst this may be true at first, taste buds soon become accustomed to less salt and you are more likely to enjoy food with less salt, and more flavour.
    • Foods high in salt taste salty. Some foods that are high in salt don’t taste very salty because sometimes they are mixed with other things like sugars that mask the taste. It is important to read food labels to find out sodium levels.
    • Only old people need to worry about how much salt they eat: Eating too much salt can raise blood pressure at any age.
    • Reducing salt could be bad for my health: Its very difficult to eat too little salt since there are so many everyday foods containing salt.

    Himalayan Salt Vs Other Salts

    Are there nutrition benefits to consuming Himalayan salt compared to other salts? Not really. All salt is composed of the molecules sodium and chloride, and according to information supplied by the USDA, Himalayan salt, sea salt and table salt are all zero-calorie foods.

    As for sodium content, brands may vary, but according to the USDA, Himalayan sea salt and Atlantic sea salt contain comparable amounts. However, Himalayan salt may contain less sodium than table salt â in some cases, up to 200 milligrams less per serving. This may allow you to sprinkle more Himalayan salt onto your food for less total sodium.

    It is also true that, compared to table salt, Himalayan sea salt contains slightly higher amounts of certain micronutrients. Per Kris Sollid, RD, dietitian and senior director of nutrition communications for the Washington, D.C.-based International Food Information Council, Himalayan sea salt boasts more calcium, iron, magnesium and potassium than table salt. But this isn’t necessarily reason enough to pay extra for the pink stuff.

    “The micronutrient differences between types of salt are small, and their resulting impact on health is insignificant,” he says.

    What You Can Do

    There are compelling evidence to support that by lowering dietary salt you can reduce risk of death from cardiovascular disease.You can adopt some of the strategies mention below to cut down in salt intake.

    Shift sense of taste

    Salt is an acquired taste. You can retrain your taste. Start by cutting down salt portion by little amount and gradually increase that amount. After about two to three months, you will get accustomed to eating food with less salt. You can also use lemon, ginger, curry, dried herbs , onion, garlic and dry mustard as natural substitute for salt.

    Eat more vegetables and fruits

    Fruits and vegetables are great source of potassium and they are naturally low in sodium. Our body requires more potassium than sodium but our modern eating habits has resulted us taking in more sodium than potassium. Eating more fruits and vegetables will help you to improve the imbalance of potassium and sodium in your body.

    Avoid processed food

    Processed food contains hight amount of sodium compare to fresh foods and they also do not contain same amount of nutrient and benefits as fresh foods. By avoiding processed food, you will be avoiding excess sodium in you diet.

    Low Sodium Intake And Cardiovascular Risk

    Know Why You Should Limit Your Salt Intake

    Over the years, the evidence of a close relationship between high sodium intake and hypertension, and high sodium intake and increased cardiovascular risk and mortality, has become increasingly consolidated. For this reason, we are used to consider that the lower the sodium intake is, the better the patient prognosis is. However, the studies that are beginning to shake the foundations of this historic fortress are growing in number. Actually, in the analysis of this topic, several cohort studies and meta-analyses have shown that the relationship between sodium intake and poor patient prognosis have not a linear trend, but rather describe a J-shape curve. In these studies, an increased risk not only in high sodium intake, but also in significantly low sodium intake levels is underlined. To reach this declaration, large patient populations have been studied, including various types of healthy patients or those with different co-morbidities , with wide numbers in all subgroups.

    Salt Doesnt Cause High Blood Pressure New Study Claims

    • Study of more than 8,000 French adults found no link between salt consumption and high blood pressure
    • 30 per cent of people in England and the U.S. suffer hypertension â high blood pressure, the most prevalent chronic disease in the world
    • Researchers found body mass index had the greatest impact on systolic blood pressure levels

    A new study has found salt consumption is not linked to higher blood pressure

    Doctors have long warned of the dangers of a high-salt diet.

    But a new study has revealed sodium does not cause high blood pressure, and the link between the two is âmore complex than once believedâ.

    Hypertension is the most prevalent chronic disease across the world.

    Known as a âsilent killerâ high blood pressure rarely has obvious symptoms.

    Around 30 per cent of people in England have hypertension, but many are unaware.

    Meanwhile in the U.S. 67 million adults suffer the condition.

    Scientists analysed data from 8,670 French adults and concluded the assumption that salt causes higher blood pressure is âoverstatedâ.

    Their aim was to evaluate the impact of lifestyle and nutritional factors on blood pressure levels.

    Despite finding no direct link, the authors of the study did note those patients who were hypertensive consumed much higher levels of salt than those without the condition.

    Their findings suggest salt affects people in different ways.

    How To Reduce Salt In Diets

    Government policies and strategies should create environments that enable populations to consume adequate quantities of safe and nutritious foods that make up a healthy diet including low salt. Improving dietary habits is a societal as well as an individual responsibility. It demands a population-based, multisectoral, and culturally relevant approach.

    Key broad strategies for salt reduction include:

    • government policies – including appropriate fiscal policies and regulation to ensure food manufacturers and retailers produce healthier foods or make healthy products available and affordable
    • working with the private sector to improve the availability and accessibility of low-salt products
    • consumer awareness and empowerment of populations through social marketing and mobilization to raise awareness of the need to reduce salt intake consumption
    • creating an enabling environment for salt reduction through local policy interventions and the promotion of healthy food settings such as schools, workplaces, communities, and cities
    • monitoring of population salt intake, sources of salt in the diet and consumer knowledge, attitudes and behaviours relating to salt to inform policy decisions.

    Salt reduction programmes and programmes that promote fortification with micronutrients of salt, condiments or seasonings high in salt can complement each other.

    Salt consumption at home can be reduced by:

    Other local practical actions to reduce salt intake include:

    You May Like: Why Is My Blood Pressure So High

    Does Salt Raise Blood Pressure Instantly

    Relation between sodium intake and high blood pressure is well established. Dozen of studies have shown that there will be spike in blood pressure when you intake salt although some people are more salt-sensitive than others. Any elevation should be temporary. Although temporary rise in blood pressure is not of concern but consistent high intake of dietary salt can result in sustain high blood pressure which can cause serious damage to the body.

    Why Salt Raises Blood Pressure

    How Does Salt Increase Our Blood Pressure?

    When you ingest more salt than you need, your body begins to retain water in an effort to wash the salt out of itself. The extra water accumulates in body tissues and raises the volume of blood in your body, explains the American Association of Kidney Patients. This extra volume puts pressure on your blood vessels. This extra pressure causes high blood pressure in some cases, especially if your blood pressure was higher than normal to begin with, or if you have other hypertension risk factors, such as kidney disease, heart disease or obesity.

    Acute Effects Of Ouabain And Eo: Augmentation Of Ca2+ Signaling And Vasoconstriction

    We now consider the direct effects of low-dose ouabain on arteries. Almost all of the studies described in this section were performed with plant ouabain because sufficient purified EO is not available. A single study, however, performed with human EO indicates that ouabain and EO have virtually identical acute effects on arteries and on cardiac muscle . Here we summarize the evidence that many of the observed functional and structural alterations in arteries from hypertensive humans and animals may be consequences of the elevated plasma EO. Indeed, the increased SNA and altered arterial function should be synergistic in driving sustained BP elevation.

    The cardiotonic effects of low-dose cardiotonic steroids are widely recognized: inhibition of 2 Na+ pumps raises sub-PM . This leads to an NCX-mediated gain of and augmentation of cardiac contraction . Similarly, low-dose ouabain augments Ca2+ signaling, vascular myogenic tone, and agonist-induced arterial constriction in rodents the ouabain EC50 is on the order of 109 M . Infusion of low-dose ouabain in humans, too, leads to acute vasoconstriction and increased TPR .

    Are You Salt Sensitive

    As many as one in four Americans with normal blood pressure is salt sensitive, and half of all people with high blood pressure are sensitive to salt, according to the AHA.

    There is no definitive blood test that can say if you are one them, Dr. Bakris says, adding that one way to know for sure if you are salt sensitive is to measure your blood pressure with a reliable home device before and after a high-salt meal. “If it has gone up more than 10 to 15 mm Hg without anything else changing, you are,” he says. Other testing methods involve a hospital stay or weeks of monitoring your diet.

    AHA suggests that cutting back on salt by 1,000 mg a day can improve blood pressure. Along with the Mayo Clinic, it offers these tips to reduce your salt intake:

    • Choose “low-salt” or “low-sodium” foods
    • Read food labels and avoid products with more than 200 mg of sodium per serving
    • Eat more fresh fruits and vegetables
    • Use spices and herbs for flavor instead of salt
    • Skip the salt in recipes
    • Cut back on condiments that are high in salt, such as soy sauce, salad dressings, ketchup and mustard

    If you are concerned about your blood pressure, Dr. Bakris suggests talking to your doctor to find out what else you should be doing to keep it in the normal range and protect your heart.
