The body needs a small amount of sodium to function, but most Americans consume too much sodium. High sodium consumption can raise blood pressure, and high blood pressure is a major risk factor for heart disease and stroke. Most of the sodium we consume is in the form of salt.
How does salt affect blood pressure?
Research shows a strong relationship between the amount of salt consumed and raised levels of blood pressure.
When salt intake is reduced, blood pressure begins falling within weeks in most people.
In countries where people consume diets low in salt, people do not experience the increase in blood pressure with age that is seen in most Western countries.
Reducing sodium intake lowers blood pressure, with greater effects among people with hypertension.
Reducing Sodium and Reducing Cardiovascular Disease Burden
Lowering high blood pressure reduces the risk of heart disease and stroke. Adults with elevated and high blood pressure especially benefit from lowering their blood pressure.
If manufacturers gradually reduced the amount of sodium in processed and prepared foods, public consumption of sodium could be reduced to safer levels with little or no change in behavior on the part of the individual consumer.
Sodium intake from processed and restaurant foods contributes to high rates of high blood pressure, heart attack, and stroke. Because nearly 500,000 deaths each year are related to high blood pressure, reducing sodium intake could prevent thousands of deaths annually.
Reducing average population sodium intake to 2,300 mg per day may save $18 billion in health care dollars and reduce cases of high blood pressure by 11 million annually.
Sodium reduction continues to be an effective and safe strategy to lower blood pressure.
Lowering blood pressure reduces and prevents heart attacks and stroke.
Hypertension is having blood pressure that is consistently high. Learn more about how elevated and high blood pressure are defined.
