WASHINGTON (AP) -- The government is telling half of the U.S. population to drastically cut their daily salt intake. That's the advice to consumers - and the food industry - as the government issues new dietary guidelines, which are the recommendations behind the popular food pyramid. For the first time, the Agriculture and Health and Human Services departments, which issue the guidelines every five years, are telling people who are 51 and older, all African-Americans and anyone suffering from hypertension, diabetes or chronic kidney disease to reduce daily sodium intake to little more than half a teaspoon.
