Correct. You’ll note that 1500mg is less than 2400 mg.
RL has always made it clear that they go off IOM figures. So the DRI, according to IOM, is 1500mg.
(Daily value comes from FDA. FDA actually takes DRI into account when they determine daily value.)
The American Heart Association used to subscribe to the (relatively) vague limit set by FDA, but they now endorse IOM’s figures.
“Previously, the American Heart Association sodium recommendations set the limit at no more than 2,300 mg/day for the general population and 1,500 mg/day for hypertensive individuals, blacks, and middle-aged and older adults. CDC released data in 2009 showing that nearly 70% of the U.S. population is made up of the groups for whom 1,500 mg a day sodium is recommended. 90% of Americans adults are expected to develop high blood pressure in their lifetimes, and eating too much sodium is strongly linked to the development of high blood pressure. For these reasons and because the potential public health benefits of sodium reduction are significant and extend to all Americans, AHA in 2010 chose to recommend that Americans eat less than 1,500 mg/day sodium as part of the definition of ideal cardiovascular health.”
