People with high blood pressure are often advised to limit their salt intake, but can a low-sodium diet have the same blood pressure-lowering effect as medication? Researchers found that reducing salt intake by 1 teaspoon per day may be as effective as taking blood pressure medications. The findings were published at the 2023 American Heart Association Scientific Sessions.

High blood pressure may increase the risk of heart disease!Study: Reducing salt intake can help lower blood pressure
Hypertension is a state of excessive arterial pressure, defined as systolic/diastolic blood pressure exceeding 130/80 mmHg). About 1 billion people worldwide suffer from hypertension, and it accounts for all heart disease and heart disease in the world. Strokes account for about half of all deaths.
Generally speaking, various factors such as age, lack of exercise, unhealthy diet, smoking, obesity, and stress may increase the risk of hypertension. Intake of high-sodium foods in daily diet is also one of the risk factors. Therefore, the United States The Heart Association recommends consuming less than 1,500 milligrams of salt per day.
According to 1 article published in “Jama Network”new researchby reducing salt intake, nearly everyone, including those taking medication for high blood pressure, could achieve a blood pressure-lowering effect, and participants who reduced their salt intake by 1 teaspoon per day saw their systolic blood pressure drop by approximately 6 millimeters of mercury. column (mm Hg), which is comparable to the use of blood pressure-lowering drugs.
Norina, a professor of preventive medicine and co-principal investigator at Northwestern University’s Feinberg School of Medicine. Norrina Allen said that the first study showed that people who were already taking blood pressure-lowering drugs could further lower their blood pressure by limiting sodium intake, and 70 to 75% of people, regardless of whether they were taking blood pressure-lowering drugs, were able to further lower their blood pressure. Blood pressure can still be lowered by reducing sodium intake in the diet.
The researchers divided 213 participants between the ages of 50 and 70 into a high-sodium diet group (consuming about 2,200 milligrams of sodium per day in addition to their regular diet) and a low-sodium diet group (consuming a total of about 500 milligrams of sodium per day). Sodium), the experiment lasted for 1 week, and at the end of the first week, the participants switched to another diet for another 1 week, and their blood pressure was measured after each study.

Among the 213 participants, the researchers said that systolic blood pressure was significantly lower by 7 to 8 millimeters of mercury in the low-sodium diet group compared with the high-sodium diet group, and by 6 millimeters of mercury compared with the regular diet group. Mercury.
Overall, 72% of participants experienced a decrease in systolic blood pressure while on a low-sodium diet compared with a regular diet. In addition, the research team also pointed out that the blood pressure lowering effect can be seen just by adjusting the participants’ sodium intake for one week.
Cora Lewis, a professor of medicine at the University of Alabama at Birmingham, said that because high blood pressure is a potential health problem that will have a significant impact on the world, the findings from the study , the fact that blood pressure fell so dramatically in just 1 week and was well tolerated is important and emphasizes the importance of reducing dietary sodium intake.
