Program Description

Chair:  Dr. Doug Bolster

Co-Chair:  Dr. Nancy Rodriguez

This session will provide an overview of contemporary topics in the rapidly expanding area of protein research.   Dr. Heather Leidy will discuss the emerging area of appetite regulation by acute protein ingestion and the influence of meal occasion on subsequent food intake. Dr. Marian Hannan will dispel the myth that higher protein intakes are harmful to bone. Specifically, the impact of dietary protein intake on bone metabolism in the context of current recommendations related to habitual protein intakes in excess of the RDA but within the AMDR.  Finally, Dr. Robert Wolfe will explore the changing perspective of protein requirements and its translation to the quality of dietary proteins.

Learning Objectives

At the end of this session, attendees will be able to:

• Describe the role of protein, specifically quantity and timing of intake, in the regulation of appetite control and satiety.
• Describe the positive effects dietary protein can have on regulating bone turnover.
• Consider dietary requirements for protein in light of the prevention of deficiencies versus optimal intake, respectively, as well as understand current perspectives on the amount and timing of protein intake in the context of health.
