A latest study has found that it is not sodium that has adverse effect, but is potassium that improved blood pressure in teen girls.

The study discovered that intake of 3,000 mg per day of salt or more didn't have any adverse effect on blood pressure in adolescent girls, whereas, those girls consuming 2,400 mg per day or more of potassium showed lower blood pressure at the end of adolescence.

Historically, the scientific community used to believe that most people in the United States consume a lot of salt in their diets.

The current Dietary Guidelines for Americans has recommended all to limit the intake of sodium to less than 2,300 mg per day for healthy individuals between the ages of 2 and 50.

According to the study background, the relationship between dietary sodium and blood pressure in children and adolescents was largely unexamined in prospective studies,

Lynn L. Moore of the Boston University School of Medicine and co-authors didn't find any evidence showing that higher sodium consumption had any adverse effect on adolescent blood pressure.

As per some analysis the girls, who consumed 3,500 mg per day or more of salt had generally lower diastolic blood pressures as compared to the ones, consuming less than 2,500 mg per day. Consumption of food was based on self reports and their blood pressure was measured annually.

The study finding showed that, on the whole, girls of the highest category of potassium consumption that is 2,400 mg per day or more had lower late-adolescent systolic and diastolic blood pressure as compared to those girls who consumed less potassium.

The results also found that the girls, consuming most sodium and potassium consumed the most calories too, along with the most dairy, fruits, vegetables and fiber.

The study has emphasized on the need of developing methods to estimate salt sensitivity to be used in future studies of high-risk populations. It has also pointed out towards the potential health risks linked to the existing low dietary potassium consumption among US children and adolescents.
