Most Americans consume way too much sodium, with salt (sodium chloride) being the most common form. That can be a serious health hazard, because excess sodium consumption contributes to the development and escalation of high blood pressure, a leading cause of heart disease, kidney disease, and stroke.
Research shows that Americans consume on average about 3,300 milligrams (mg) of sodium every day. The 2010 Dietary Guidelines for Americans recommends a reduction of sodium intake to less than 2,300 mg daily.
And those age 51 and older, and people of any age who are African-American or have high blood pressure, diabetes or chronic kidney disease should further reduce sodium intake to 1,500 mg daily. This amount meets your essential need for sodium. These populations comprise about half the U.S. population.
The Centers for Disease Control and Prevention (CDC) recently reported that children and adolescents consume about the same amount of sodium as adults and also risk developing high blood pressure. The researchers found that kids who consumed the most sodium faced double the risk of having high blood pressure, compared to those who took in less sodium. For overweight or obese children, the risk was more than triple.
“There has been a common misconception that sodium intake is just a concern for people with high blood pressure,” says Jessica Leighton, Ph.D., MPH, senior advisor for science in the Food and Drug Administration’s Office of Foods and Veterinary Medicine. “But it’s a health risk for all people, including children, as the CDC report shows.”
FDA is working on a number of fronts to help consumers manage their sodium intake.
