While some of us experience a rise in blood pressure after eating salty foods, there are people who might feel lucky being able to avoid high blood pressure caused by consuming sodium. However, a recent study proved that nobody is safe from the negative effects of salt.

Proven By Science

Most of us look at salt as seasoning for our favorite meals, but as you’ll soon find out, salt is a lot more than just something you can add to a dish to give it more flavor.

According to a team from the University of Delaware College of Health Sciences, even when it doesn’t cause an increase in blood pressure, excess dietary salt can still greatly impact your organs, such as blood vessels, kidneys, heart, and brain.

William Farquhar, a co-author of the study, said: “Blood pressure responses to alterations in dietary sodium vary widely, which has led to the concept of ‘salt-sensitive’ blood pressure.

“There are no standardized guidelines for classifying individuals as having salt-sensitive blood pressure, but if blood pressure increases during a period of high dietary sodium or decreases during a low-sodium period, the person is considered salt sensitive. If there’s no change in blood pressure with sodium restriction, an individual is considered salt resistant.”

Reasons To Be Careful

You’re probably wondering now “How much damage can salt actually do to me?” To answer that question, we’ll look into every part of our organism dietary sodium can affect in a bad way.

First off we have artery damage. Salt can reduce the function of the endothelial cells, which are responsible for coagulation and immune function.

Next up are the kidneys. Dietary sodium is linked to reduced renal function and the forming of kidney stones, and we don’t need to explain how uncomfortable and dangerous that can be.

Last, but certainly not least, is salt’s impact on our nervous system. As Farquhar said: “Chronically elevated dietary sodium may ‘sensitize’ sympathetic neurons in the brain, causing a greater response to a variety of stimuli, including skeletal muscle contraction.”

“Again, even if blood pressure isn’t increased, chronically increased sympathetic outflow may have harmful effects on target organs.” So think twice the next time you’re about to add a pinch of salt to your favorite dish, because it may not be worth it.
