People with diabetes have a higher risk of high blood pressure which can result in stroke, heart and kidney diseases. So, it is important for patients to manage their blood pressure to prevent it from going up. And, one of the ways to do that is by watching the quantity of our sodium intake. Sea salt and dead sea salt both have sodium, but which one is best for diabetes and high blood pressure?

Sodium is a vital mineral our body needs to balance the fluid in our body and control blood pressure. It is also needed for the proper functioning of the nerves and muscles.

Sea salt is a good source of sodium. A lot of people opt for sea salt in place of table salt because they believed that since it is unrefined, it is healthier. But the truth is that It contains almost the same amount of sodium chloride as the common table salt but with other 82 minerals in trace quantity which are beneficial to the body.

Sodium is an essential nutrient, but the quantity you consume has a direct effect on your blood pressure.

Dead sea salt is another type of sea salt, used for therapeutic purpose, it has a lower quantity of sodium and high quantity of other minerals which can help to improve the conditions of a patient with diabetes and high blood pressure.

When Managing diabetes and high blood pressure cutting down your salt intake does not mean your food has to be bland or tasteless. For example, you can use a salt substitute that uses potassium and magnesium in place of sodium. You can also use more natural spices like thyme, ginger, cayenne peppers, oregano, nutmeg etc.

To help to address the main question of this guide the differences between Sea Salt vs Dead Sea Salt, and their effects on Diabetes and Hypertension, let’s identify each salt type first.

What is Sea Salt?

Sea salt, also known as bay salt, are salt obtained by evaporating salty seawater or ocean water. Unlike our common table salt that is refined using different processing like bleaching, iodizing and diluting, sea salt is untreated, pure, natural and darker than the table salt.

The difference when using sea salt instead of table salt for cooking is that the sea salt has other minerals aside from sodium chloride, but these minerals are in trace quantity! And no iodine! And our body really needs iodine for the proper functioning of the thyroid gland.

Sea salt contains a little amount of natural iodine but as not as the iodine content in the common table salt. Sea salt depending on the source and method of extraction varies in grain size from fine grain to coarse, irregular shapes and flakes. It also varies in colors, flavor and amount of sodium chloride and trace elements.

What is Dead Sea Salt?

Dead Sea salt refers to salt obtained from the Dead Sea.

Don’t be misled, the dead sea is not actually an ocean or a sea but a salt lake that lies in the Jordan rift valley with River Jordan as the main tributary.

The dead sea itself is also a type of sea salt, but its composition differs significantly from other types of sea salt.

Dead sea salt ls not used as a food seasoning, but for beauty and therapeutic purposes. This is because the minerals found in Dead Sea salts which are magnesium, calcium, iodine, zinc, bromide, potassium and sulfur are similar to minerals found in the skin cells and are beneficial for anti-aging, keeping the skin healthy and well-nourished.

Differences of Dead Sea Salt from Common Sea Salt?

The Dead Sea salt is extracted from the dead sea while sea salt is obtained from evaporating salty seawater or ocean water from any part of the world.

Dead sea salt is used for therapeutic and skincare purposes, while common sea salt is used in cuisine and cooking purpose.

The dead sea salt has only about 12 to 18 % sodium chloride. It is rich in mineral compounds, having about 21 minerals with magnesium, calcium, potassium, chlorides, sulfur and bromides in higher concentration. The low sodium chloride content makes the dead sea salt not to be an acceptable cooking salt. The rich mineral content makes it to taste bitter.

Meanwhile, the sea salt has about 97 % sodium chloride while the remaining percentage contains an 82 trace element. Since it has almost the same percentage of sodium chloride as the table salt, it is used for cooking and the additional trace element though it may be in little quantity but is an added bonus.

Sea salt is mainly used for culinary purposes whereas Dead Sea salt are used for therapeutic purposes

It is also claimed that the potassium in it helps to reduce water retention in the body, which will help with diabetes-related edema.

Which Salt is Best for High Blood Pressure? Why?

Sodium chloride is the main mineral in sea salt.

The sodium ion is the electrolyte that regulates and balances the fluid in our body, sends electrical signals to the nervous system and balances the blood pressure. Lack or insufficient it in our body can result in Hyponatremia which causes dehydration, confusion, muscle spasm, seizure and even death.

Excess sodium can cause your body to retain water, and when you eat too much of it, your body can retain too much water which can increase your blood pressure and putting more strain on your heart, kidney, arteries and brain. This can result in stroke, kidney problem, heart attack and dementia.

Salt substitutes have salty tastes that is as a result of other compounds aside from sodium chloride. They use potassium and magnesium to substitute the sodium thereby reducing the daily intake of sodium and the consequent health effects of high sodium intake.

The most commonly used salt substitute is potassium chloride with the chemical formula KCl. It has almost the same level of toxicity as sodium chloride for a healthy person.

When used in high quantity, potassium chloride may have a bitter aftertaste.

Other salt substitutes that include magnesium and potassium as their primary substance are Carnallite, Kainit, langbeinite, sylwinite, polyhalite and kieserite.

Salt substitutes with potassium are not recommended for diabetics or people with heart diseases or kidney diseases because their body may not be able to excrete the potassium which may result to excess potassium in the body known as hyperkalemia.

Hyperkalemia can cause muscle pain and weakness, and irregular heartbeat, which may lead to cardiac arrest and death.


Although sea salts are natural, unrefined salt and with many elements in trace amount which our body needs and without additives, but it still has a high quantity of sodium. So the key to using sea salt is to use it in moderation.

Also, for people with hypertension, cutting down your salt Intake (not eliminating) one way to help manage your blood pressure. Dead sea salt, on the other hand, is lower in sodium with other minerals in larger quantity which has a lot of beauty and health benefits. It can be used to manage diabetics and high blood pressure-related symptoms, but since it is not edible, salt substitutes can be used for cooking to minimize sodium intake.
