Program Description

Public policy on sodium and health has focused on limiting the populations’ sodium intake for putative health concerns. This symposium will explore the neuro and systemic physiology underlying the regulation of sodium appetite. Specifically the presentations will cover how interrelated neural networks that control sodium intake respond to peripheral hormonal signals directed at maintaining optimal organ perfusion. In that context, the relation of these neurological pathways to optimizing systemic cardiovascular physiology and thereby reducing cardiovascular risk will be discussed. How this complex physiology of sodium appetite maybe incorporated into setting nutrition guidelines will also be considered.

Moderators:
David A. McCarron, MD, University of California, Davis
Suzanne Oparil, MD, University of Alabama at Birmingham

Learning Objectives

• Describe the neural pathways regulating sodium appetite and primal nature of the neural control of sodium appetite;
• Describe the interface between neural mechanisms and peripheral sodium homeostasis;
• Explain the specific neural responses to a range of sodium intake that modulate CVD risk and the peripheral and neural physiology of sodium control as it impacts CVD risk;
• Describe how complex regulatory mechanisms are evaluated in setting of DRIs and Guidelines
