Researchers have conducted the study on girls aged 9 and 10 years. They had a total of 2,185 black and white girls for the study.
Researchers have observed the sodium and potassium intake in their diet for 10 years.
They have yearly monitored the blood pressure of the teenage girls who regularly consumed 3,000 milligrams of potassium per day.
After they have analyzed the data they found that the teenage girls did not develop high blood pressure at the end of their adolescence.
There were girls who consumed 2,400 milligrams or more potassium per day and at the end of their adolescence they had low pressure compared to girls who had lower potassium intake.
So the researchers said people who have potassium rich diet will be having more health benefits than people who are having low salt diet. So potassium intake should be increased in the diet.
The study revealed that higher salt intake will not have any effect on blood pressure at the end of adolescence.
But 2,300 milligrams of sodium per day is recommended for individuals from ages 2 to 50 by Dietary Guidelines for Americans.
Nutritionists and dieticians recommend limiting salt intake to 1,500 mg per day for individuals diagnosed with kidney disease and diabetes.
World Health Organization recommends at least 3,510 mg of potassium a day for adults.
Potassium helps maintaining muscle mass and regulates heartbeat and also minimizes risk of heart disease and stroke.
Dr. Lynn L. Moore, associate professor of medicine in Boston University, and lead author of the study said, “It may be that potassium is more of a determinant of blood pressure than sodium is. The kids who consumed the most potassium had much lower blood pressures by the end of adolescence. What we need to focus on is increasing potassium intake rather than focusing on restricting sodium intake.”
