In this 6-part series of How a Low Sodium Diet Helps to Control Hypertension, we will be looking at the link between sodium and hypertension. By the end, we hope you’ll have a thorough understanding of how a low sodium diet can help you control hypertension. Greater understanding of the subject can lead to healthy lifestyle choices for health and wellness products.

In Part 1 of this blog, called Sodium Intake and Blood Pressure, we will cover sodium intake and blood pressure values to help build your foundations of controlling hypertension.

The Direct Relationship Between Sodium Intake and Blood Pressure

As you may already be aware, excess consumption of sodium leads to increase blood pressure. Wondering what is classified as excess consumption? The World Health Organization (WHO) recommends consuming less than 5g of salt each day. This equates to 2g of sodium. Anything more is considered as excess consumption. Excess sodium consumption has been linked to an onset of hypertension along with cardiovascular complications1.

Lower sodium intake can decrease your blood pressure as well as your hypertension incidence. Additionally, it can reduce cardiovascular disease and mortality1.

34 trials with 3230 participants was conducted where salt intake was reduced for at least 4 weeks. The conclusion from these studies were that modestly decreasing salt intake over 4 or more weeks caused significant and important falls in blood pressure for those with hypertension and those with a normal blood pressure2. Lower salt intake can therefore result in reducing your cardiovascular disease risk.

The Pathophysiological Link Between Sodium Intake and Blood Pressure

For those that aren’t aware, pathophysiological refers to the functional changes associated with or resulting from injury or disease. So, what is the  pathophysiological link between sodium intake and blood pressure, a topic that has been widely debated.

With increased consumption of salt, there may be retention of water in your body, which can lead to a condition of higher flow in your arteries. A pressure of your kidneys to excrete sodium through urine is described to be a normal phenomenon where increased salt and water excretion occurs due to an increase in blood pressure in the renal arteries1.

When there’s high sodium intake with increased blood pressure levels, there are changes in vascular resistances. However, this is viewed to be a reflex response so that there is an increase in sodium excretion1.

There are several adverse effects from excessive salt intake. This includes an inflammation of the endothelial cells (cell layer that lines your blood vessels), an abnormal change in the structure of your endothelial cells and functional abnormalities1.

Healthy Salt for a High Blood Pressure Sodium Diet

As you may already know, salt contains sodium. As discussed above, an excess consumption of sodium leads to an increase of your blood pressure.  By lowering your sodium intake, you can decrease your blood pressure, your hypertension incidence, your cardiovascular disease risk and mortality risk. One way you can reduce your sodium intake includes switching to the best healthy salt like Heart SALT, which has 56% less sodium than regular salt. Heart SALT is a suitable salt for a high blood pressure sodium diet and is the best salt for heart patients.

In Part 2 of How a Low Sodium Diet Helps to Control Hypertension, we will be covering low sodium intake and cardiovascular risk.
