Small increases in dietary sodium linked to high blood pressure

Salt-SMALLA large scale Japanese study published in the journal of the American Heart Association has revealed that even small increases in salt consumption may increase blood pressure substantially after several years.The researchers recommend reducing daily salt intake.

The participants consisted of 4, 523 people with normal blood pressure, whose salt consumption was analyzed by the amount of sodium in urine and who were followed for a period of three years. Follow-up urine analysis continued for about . The daily recommended allowance for sodium intake is 1,500 milligrams.

The study analysis revealed that a quarter of the health population developed high pressure over a 3 year period and people who consumed the most salt were most like to develop high blood pressure.

“In our study, it did not matter whether their sodium levels were high at the beginning of the study or if they were low to begin with, then gradually increased over the years – both groups were at greater risk of developing high blood pressure, said Dr. Tomonori Sugiura – lead author and an assistant professor in the cardio-renal medicine and hypertension department at the Nagoya City University Graduate School of Medical Sciences in Nagoya, Japan.

“Americans consume an average of nearly 3,500 milligrams of sodium a day, which is about 1,000 milligrams more than any public health group recommends. Reducing sodium intake can save lives, save money and improve heart health – no matter what background or nationality a person is.”
