Is high blood pressure linked to salt, or sugar?
By Real Salt | Published: December 28, 2011

A certified nutritional therapist, Craig Fear, recently wrote a blog post we liked so well, we asked him if he’d like to share it on the Real Salt blog as well. If you’re into nutrition you’ll want to check out Craig’s website, and if you’re into being healthy (who isn’t?), take a few minutes to read this post!
Why Sugar Will Raise Your Blood Pressure More Than Salt

By Craig Fear, NTP – Certified Nutritional Therapist

To salt or not to salt, that is the question.

According to your doctor, your government, just about every major health organization, and probably your mother (at least mine) salt will raise your blood pressure. This thinking is so pervasive that it’s taken as a fact by just about everyone.

It also sells A LOT of drugs.

I ended last week’s blog about bone broths with four tips to ensure a good supply of minerals in the diet. My last tip was to consume salt liberally. I then proclaimed that there is no connection to salt intake and high blood pressure.

OK, I lied.

I admit it. There is a connection.

But it’s not nearly as much as you think.

Let me explain why in a somewhat roundabout way.

Carbs and water weight

As part of my nutrition practice I teach a 12 week group weight loss class. The program is called “Get at the Roots” because each week we discuss a different underlying cause of weight gain with steps to correct it. Class members learn to address their digestive issues. They learn to identify hidden food sensitivities . They learn how to correct fatty acid deficiencies, hormonal imbalances, brain chemistry deficiencies and many others.

However, the most important underlying issue is addressed in week 1. This is the ultimate foundation. Everything is predicated on this. And that is carbohydrate restriction. More specifically, refined carbohydrate restriction (notice I did not say calorie restriction). Class members learn right from the start that it is not how much they eat but what they eat that is most important.

In week 1 we discuss the Science of carbs and see how they’re broken down into Sugar in the body. We then see how too much Sugar in the blood is dangerous and how the body converts and stores sugar as fat.

We take a historical look at the evolution of the American diet in the 20th century and see the clear influence of industry with the rise of refined carbohydrates. We see a clear connection to this trend and the rise of chronic diseases in industrialized countries.

We explore the bad Science that has led to the idea that fat is bad. We dismantle the myth that fat makes us fat and we learn how vital it is to our body’s functioning. And we learn how fat and protein switch the body’s metabolism from fat storing to fat burning.

“Yeah yeah yeah, so what does this have to do with salt?!” you ask.

Generally speaking most class members lose the most weight in the first two weeks of the 12 week class. But they’re not really losing fat. They’re losing water. Why?

Carbohydrates cause the body to hold on to water. When the water volume increases in our blood, the pressure in our blood vessels increase.

The same can happen when we consume salt.

However, only one of these will cause chronically elevated blood pressure. Let’s see which one is the true culprit.

Understanding Salt

Salt is composed mostly of sodium and chloride. We can’t live without either. Our blood, sweat and tears are salty. Sodium and chloride play vital roles in nerve conduction, muscle contraction (including the heart), digestion and blood pressure, to name a few.

As with everything, our body regulates their concentrations so they don’t get too high or too low.

Sodium’s concentration in our blood is maintained by water. The kidneys job is to maintain this concentration. Consume more salt and your kidneys will excrete it into the urine along with water to flush it out. Consume less salt and the kidneys will hold on to water to maintain the concentration.

So when we consume salt, the blood pressure goes up slightly as the kidneys work to maintain the right concentration. And vice versa. This has given us the belief that reducing salt in our diet will lower our blood pressure. Of course it does, but here’s the million dollar question:

Does it drop our blood pressure enough to resolve chronically high blood pressure?

And the answer is a resounding NO!

Reducing salt in your diet has a minimal effect on lowering your blood pressure. Because salt is so vital to your health, your body will hold on to it in your bloodstream so it doesn’t get too diluted. If you have high blood pressure, study after study has shown that a significant reduction of salt in your diet will only drop it 2-5 millimeters of mercury (mmHg).

Hypertension is defined as having a systolic pressure (top number) of at least 20 mmHg over normal and a diastolic pressure (bottom number) at least 10 mmHG over normal. Normal is considered 120/80 mmHg so hypertension is defined as being above 140/90 (Prehypertension is the range between normal and hypertension). Therefore, reducing hypertension by 2-5 mmHg via salt restriction when you’re already at least 20 mmHg over what is considered normal just gets you slightly less hypertension. This does not resolve hypertension.

To put it in perspective let’s visit re-visit the Weston A. Price Wise Traditions Conference.

The History of Salt

On Saturday at the conference I saw Morton Satin speak. Morton is known as the Salt Guru and is the Vice President of Science and Research for the Salt Institute. Morton’s talk, “Salt Myths,” took on the concept that salt is bad for us and will raise our blood pressure.

Dissecting flawed study after flawed study, Morton reminded everyone that before the advent of refrigeration, foods were preserved and cured in salt and that contrary to popular belief salt has dramatically decreased in our diet since WWII. In fact, ‘sal’ is Latin for the word salt. In Roman times, sal-ad was traditionally meant to be vegetables and salt or a salty dressing. Similarly the word ‘salary’ also comes from the Latin ‘sal’ as Roman soldiers were paid in salt.

Go to the “history of salt” page on Wikipedia. Here’s what the first sentence reads: “Salt’s ability to preserve food was a foundation of civilization.” If you read further, you’ll see that humans have gone to great lengths throughout history to secure salt. Empires have risen and fallen due to salt trade routes and salt production.

Furthermore, salt’s use as a healing remedy dates back thousands of years. Cultures throughout the world have found healing properties to salt water. Could this possibly be a reason so many of us are drawn to the ocean?

In fact, salt is so vital to your health, that not getting enough can have adverse health consequences including an increase in your likelihood of hypertension and cardiovascular disease, the very conditions we’re told are related to too much salt.

The True Culprit

So if it’s not salt, what is it?

It seems like in everything I write, in all my public talks, in all my discussions about nutrition, I somehow find my way to this statistic:

The average American consumes 150 pounds of refined sugar per year.

We are so used to it in our diet that we don’t realize it’s relatively new historically speaking. Prior to industrialization, making refined sugar from sugar cane was a long and laborious process. The sugar industry was built on the back of the slave trade. Initially, only wealthy Europeans could afford it. This is also the first evidence we see of diabetes.

With the advent of industrialization in the 19th century, industry took over for slave labor and made the manufacturing more efficient. Throughout the 20th century, sugar became increasingly available to everyone as the food industry put it in everything.

This is without question the root reason to our type II diabetes epidemic (chronically elevated blood sugar). This is the root reason to our obesity epidemic as the body stores excess sugar as fat. And yes, it’s the root reason to hypertension.

Hypertension is a condition of industrialized societies. Countless researchers including Dr. Price did not find hypertension in non-industrialized societies despite many cultures liberally consuming salt in the form of Sea Salt , sea vegetables and salt-preserved foods. Nor did they find rampant sugar consumption.

We know that hypertension goes along with obesity, heart disease and diabetes, the so called diseases of civilization.

Again, too many refined carbohydrates increase water in the blood thus increasing blood pressure. Refined carbs have no nutrients. The nutrients are stripped out in the refining process. As we’ve seen the body must maintain sodium in the bloodstream or significant health problems will ensue. Consider that an intravenous solution of salt water is the first thing given to ER patients.

So if the body is not getting sodium through the diet it must retain it. It will do this by retaining water in the blood vessels to maintain the concentration of sodium. Thus, blood pressure rises and thus we get hypertension.

And this is why most people lose the most weight in the form of water in the first two weeks on carbohydrate-restricted diets. This is exactly what happens in the weight loss program I teach.

And of course, class members blood pressure drops as well. Many stop their blood pressure medications.

This is just one of the many benefits that come with restricting sugar and processed carbohydrates. For others cholesterol comes down, creaky joints feel better, mood improves and so on.

What about the studies?

You would be surprised just how many studies exist that shows no connection to salt and hypertension. So forget the studies. Study it in yourself. If you have hypertension, reduce your salt intake for two weeks and do nothing else (you’re probably already doing this). See if that brings down your blood pressure significantly. If not, eliminate all sugar intake in the form of refined sugar and refined carbs for two weeks. See what happens.

Please note there are some medical conditions that are can be exacerbated by increased salt intake such as kidney failure and congestive heart failure. Consult your doctor if you have a serious medical condition.

Sources of salt

Of course not all salt is created equal. Most Americans use processed salt which is stripped of trace minerals and full of anti-caking chemicals such as aluminum which make salt easier to sift.

God forbid we might have to use real salt that doesn’t come out of matching porcelain salt and pepper shakers. Oh, the inconvenience.

Yes, Nature’s true salt, Sea Salt , forms clumps. It is also offers a wonderful supply of trace minerals which the body needs for so many biochemical processes.

There are many healthy sources of Sea Salt in health food stores. Many people have favorite brands for different reasons. I like Redmond Sea Salt which is mined from ancient sea beds in Utah. Others prefer Himalayan sea salt or Celtic sea salt.

Finally, the last question I get from many people.

How much salt is too much salt?

Dr. David Brownstein, a holistic doctor who specializes in treating thyroid issues and the author of Salt Your Way to Health recommends at least a teaspoon per day of unrefined salt.

But don’t discount your innate intelligence! Innate intelligence communicates to you through your taste buds. If you’re craving salt, salt your food. You’ll know when you’ve overdone it.
