Which salt is best for high blood pressure? Know the effects of sodium and different salt types
ETimes November 02, 2025 03:39 PM
Salt is a common kitchen essential, but for people with high blood pressure, it’s also one of the most important ingredients to monitor. Whether added during cooking or sprinkled on meals, the type and amount of salt you use can affect your heart health. Many assume that natural varieties such as sea salt or Himalayan pink salt are healthier, but this belief is largely a myth. The real issue lies in sodium content, not the salt’s colour, texture, or source. Understanding how much sodium you consume daily is key to maintaining healthy blood pressure and supporting long-term cardiovascular wellness.



Understanding how salt and sodium intake impact blood pressure and overall heart health
Salt, or sodium chloride, is vital for body functions; it helps regulate fluids, maintain nerve activity, and support muscle function. However, too much sodium causes the body to retain water, increasing blood volume and, in turn, raising blood pressure. Over time, this extra pressure can strain the heart and damage blood vessels, leading to hypertension and a higher risk of heart disease and stroke.

The crucial takeaway is that it’s not the type of salt that matters most, but how much sodium you consume overall. Different salts may vary in appearance, texture, and trace minerals, yet their sodium levels are generally quite similar.



Common types of salt and their effects on blood pressure

1. Table salt

Table salt is the standard salt found in most homes and processed foods. It’s mined from underground deposits and heavily refined to remove impurities. Usually fortified with iodine, an essential nutrient for thyroid function, it’s one of the purest and most concentrated forms of sodium. One teaspoon contains around 2,325 mg of sodium, which can easily exceed healthy daily limits if used excessively.
According to , regular use of refined table salt contributes significantly to total sodium intake, increasing the risk of elevated blood pressure and cardiovascular strain.


2. Sea salt


Sea salt is created by evaporating seawater and tends to be less processed, giving it a slightly coarse texture and unique flavour. It may contain trace minerals like magnesium, calcium, and potassium, depending on its source. However, these minerals are present in tiny amounts and offer no real health benefit compared with table salt. With about 1,872 mg of sodium per teaspoon, sea salt is still high in sodium and should be used moderately.
noted that while sea salt retains minor minerals, its sodium concentration remains nearly identical to that of refined table salt, offering no measurable cardiovascular advantage.


3. Kosher salt


Known for its large, flaky crystals, kosher salt is popular among chefs for its texture and ease of control when seasoning. Because it’s less dense, a teaspoon of kosher salt has slightly less sodium by volume, about 1,120 mg, than fine table salt. Still, it’s easy to use more due to its coarseness, which can cancel out the lower sodium advantage. It’s free from additives and iodine, making it a purer option but not necessarily a healthier one for blood pressure. A Harvard Health Review summary explains that while kosher salt contains less sodium per teaspoon, people tend to use larger quantities, leading to a similar overall sodium intake and blood pressure risk.


4. Himalayan pink salt


Himalayan pink salt is mined from ancient salt deposits in the Himalayan region and gets its distinctive pink colour from trace minerals like iron and magnesium. Despite its natural reputation, the difference in mineral content is minimal and doesn’t provide any proven health advantage. One teaspoon contains about 1,680 mg of sodium, making it comparable to regular salt in terms of blood pressure impact. It’s aesthetically appealing but not medically superior. concluded that Himalayan pink salt contains trace minerals in negligible amounts that do not significantly influence cardiovascular or metabolic health outcomes.



So, is there a “healthier” salt for high blood pressure
While various salts differ in texture and flavour, none of them is truly healthier for blood pressure. Whether it’s pink, grey, white, or flaked, all salts are high in sodium, and it’s the total intake that affects your health most. The small variations in mineral content or sodium density don’t make a meaningful difference to heart health.

People with high blood pressure should aim to reduce sodium intake, not simply switch from one type of salt to another. The recommended daily limit for sodium for most adults is less than 2,300 mg, roughly one teaspoon of salt in total from all food sources.



Smart ways to reduce sodium intake
You don’t have to eliminate salt; instead, adopt mindful habits to lower your intake while keeping food flavourful.

  • Cook more at home: This gives you full control over how much salt you add.
  • Use herbs and spices: Flavour your meals with garlic, pepper, basil, turmeric, or lemon instead of relying on salt.
  • Check food labels: Processed foods, sauces, and ready meals are often loaded with hidden sodium.
  • Rinse canned foods: Beans, vegetables, and soups can contain high sodium levels that can be reduced by rinsing.
  • Gradually cut down: Slowly reduce the salt in your diet; your taste buds will adjust over time.
  • Eat more potassium-rich foods: Bananas, spinach, avocados, and sweet potatoes help counteract sodium’s effects on blood pressure.
  • Be cautious when dining out: Restaurant meals often contain more salt than home-cooked food.



Low-sodium and potassium salt alternatives

Salt substitutes made with potassium chloride instead of sodium chloride can be a useful option for people with high blood pressure. They help lower sodium intake while maintaining a similar salty taste. Some studies suggest that these substitutes can reduce the risk of hypertension and related cardiovascular issues.

However, they’re not suitable for everyone, particularly people with kidney problems or those on medications that affect potassium levels. Always check with a healthcare professional before making the switch.
