Most People Consume Too Much Salt
Most of the sodium we consume is in the form of salt, and the vast majority of sodium we consume is in processed and restaurant foods. Your body needs a small amount of sodium to work properly, but too much sodium is bad for your health.
Americans get about 70% of their daily sodium from processed and restaurant foods.2 What is processed food?
Sodium is already in processed and restaurant foods when you purchase them, which makes it difficult to reduce daily sodium intake on your own. Although it is wise to limit your use of added table salt while cooking and at the table, only a small amount of the sodium we consume each day comes from the salt shaker.
Did you know that sodium and potassium both affect blood pressure? In general, people who reduce sodium, who increase potassium, or who do both benefit from having lower blood pressure and reducing their risk for other serious health problems. Eating enough potassium each day can help balance out some of the harmful effects that high sodium intake can have on blood pressure. But lowering sodium intake is key to this balance.
CDC works at the national, state, and local levels to help reduce sodium in the food supply. CDC’s approach to sodium reduction includes supporting and evaluating ongoing efforts to reduce sodium, providing technical assistance to the public health community, expanding the scientific literature related to sodium reduction, collaborating with stakeholders, and educating the public.
