CPE Webinar: "Balancing Sodium and Potassium Intake for Disease Prevention and Optimal Health"

This was a live event that occurred in September of 2013. If you attended this webinar and are eligible for CPE credit, please see the bottom of this page for more information.

 The IFIC Foundation is proud to cosponsor this webinar with the USDA-ARS Beltsville Human Nutrition Research Center (BHNRC) and provide 1.5 hours of Continuing Professional Education (CPE) credit to Registered Dietitians and Dietetic Technicians Registered.

This webinar will focus on the range of sodium and potassium intakes by Americans, disease conditions associated with sodium and potassium intakes, and genetic variability in response to these dietary components.

Speakers will address:

  • The relationship between sodium and potassium intakes in subpopulations in the United States.
  • Who is vulnerable to limitation or excesses of sodium and potassium.
  • How sodium and potassium influence health mechanistically.
  • Which genes are involved with the response to sodium and potassium.
  • The future research needs in this area.


  • Dr. John Milner, Director, Beltsville Human Nutrition Research Center (BHNRC) USDA–Agricultural Research Service
  • Alanna Moshfegh, Research Leader, BHNRC, Food Surveys Research Group, USDA–Agricultural Research Service
  • Dr. Lawrence J. Appel, Director, Welch Center for Prevention, Epidemiology, and Clinical Research, Johns Hopkins Medical Institutions
  • Dr. Gordon H. Williams, Professor of Medicine, Harvard Medical School, Director of the Specialized Center of Research in Hypertension, and Chief, Hormonal Mechanism of Cardiovascular Risk Laboratory, Brigham & Women's Hospital
  • Jay Green, Moderator Outreach Coordinator, USDA–Agricultural Research Service

Learning Objectives:

  1. Define how the genetic background of an individual can lead to variable expression of diseases influence by dietary intake of sodium and potassium.
  2. Provide information on the mechanisms and genes involved that can lead to salt sensitive hypertension.
  3. Describe the range of intakes for sodium and potassium and the relationship between these intakes in population subgroups in the United States and how these intakes compare to recommendations from the 2010 Dietary Guidelines for Americans and the Institute of Medicine.
  4. State the impact of select dietary patterns and behaviors on sodium and potassium intakes.
  5. Identify the major dietary sources of sodium and potassium in the American diet.
  6. Cite the importance of age and gender on response of dietary sodium intake; the main and joint effects of sodium and potassium intake on blood pressure, cardiovascular and other outcomes, including kidney disease and bone health.
