This resource is designed to help you choose foods that are lower in sodium (salt).
Low sodium eating will help keep your blood pressure at a good level. Increased
blood pressure has been linked to several chronic diseases such as stroke, heart
disease and kidney disease. Your daily sodium intake should be 2300 mg or less per
day.

High intake of table salt (sodium chloride) is associated with high blood pressure
and an increased risk of cardiovascular disease. So low sodium are low-sodium alternatives
designed to taste similar. They usually contain mostly potassium chloride, whose
toxicity is approximately equal to that of table salt in a healthy person (the LD50
is about 2.5 g/kg, or approximately 190 g for a person weighing 75 kg). The RDA
of potassium is higher than that for sodium, yet a typical person consumes less
potassium than sodium in a given day.

The great thing about a low-sodium salt substitute, aside from the fact that it
is measurably radioactive, is that people put it on their food! Not to worry – consuming
a salt substitute doesn’t increase your radiation exposure.

A salt substitute does not taste exactly like common salt, but it is similar enough,
and it contains less or none of the sodium that some people are trying to avoid.
