You may already know some of the dangers of a high-sodium diet, but did you know that it could be used to predict future high blood pressure? If your family is prone to hypertension this information could be life-saving. Read on to learn more. 

High-sodium diet may predict high blood pressure to come


As dietary sodium levels go up over time, so does the risk for high blood pressure, suggests a new study that followed more than 4,000 adults in Japan for four years.

The study did not measure dietary sodium directly, instead using urine samples to estimate levels of sodium consumed, but the results align with other large studies of sodium intake and blood pressure risk, researchers say.

“A small amount of salt (less than 3,000 milligrams a day) is necessary for us, but excessive salt is dangerous,” said coauthor Dr. Tomonori Sugiura of Nagoya City University Graduate School of Medical Sciences in Japan.

Most people eat much more than the recommended amount of sodium daily. A diet high in processed foods is one of the quickest ways to get too much salt in your diet. Just about every processed food out there has sodium and sugar added.

To excrete excess amounts of sodium, the body has to increase blood pressure, Sugiura told Reuters Health by email.

Dietary sodium levels are much higher in Japan than in the U.S., but most people eat too much in both countries, Sugiura said.

U.S. government dietary guidelines recommend consuming no more than 2,300 mg of sodium a day, equivalent to about two-thirds of a teaspoon of salt, and that people with existing high blood pressure or risk factors for it limit total sodium to 1500 mg daily.

Past research indicates the average American consumes about 3,600 mg of sodium a day.

Scientists are still debating whether high levels of sodium intake among people with normal blood pressure could cause chronic high blood pressure or other cardiovascular problems to develop.

But if it does contribute, sodium intake would be a risk factor that would be easy to modify to benefit public health, the authors write in the Journal of the American Heart Association (AHA).

The researchers used urine tests from checkup appointments to estimate the dietary salt intake of 4,523 Japanese adults without high blood pressure. The participants, who ranged in age from 22 to 85 years old, had annual physicals including sodium tests and blood pressure measurements.

The study team used these records to follow people for three or more years to see if they developed high blood pressure. During the study, 1,027 individuals developed high blood pressure, including 26 percent of the men and almost 17 percent of the women.

Having higher sodium levels at the beginning of the study and showing greater increases in sodium levels each year were both tied to higher risk of developing high blood pressure, the researchers found.
