The 2010 Dietary Guidelines for Americans recommends that people ages 2 and up limit daily salt intake to less than 2,300 milligrams. These guidelines were developed by the U.S. Departments of Agriculture and Health and Human Services
Adults ages 51 or older, all African-Americans and anyone with high blood pressure, diabetes or chronic kidney disease should limit daily salt intake to 1,500 milligrams. While the human body needs a certain amount of salt, consuming too much salt is a problem for children as well as adults. Ninety percent of adults eat too much salt, mostly in the form of processed and restaurant food. One in six children exhibit high blood pressure, a major risk factor for future heart attacks and strokes. One method of reducing salt in the diet is to eat more meals at home from healthy ingredients, because 75 percent of salt intake is from processed and restaurant foods.
