increased potassium intake and consumption of
dietary patterns based on the “DASH diet” have emerged as effective strategies that also lower BP. Of substantial public
health relevance are findings related to blacks and older individuals. Specifically, blacks are especially sensitive to the
BP-lowering effects of reduced salt intake, increased potassium intake, and the DASH diet. Furthermore, it is well
documented that older individuals, a group at high risk for BP-related cardiovascular and renal diseases, can make and
sustain dietary changes.
