A part of Medical Nutrition's Continuing Education (CE) program, credits are available for healthcare professionals that attend.

Cost to participate is $40. The CD-HCF's website address describing the program is here: http://www.cdhcf.org/essentials/events.asp.

The May 13 program discusses new data that point to the fact that aging increases the need for dietary protein and that many elderly people consume a marginal or inadequate amount of protein, resulting in an accelerated rate of sarcopenia or loss of skeletal muscle mass. The webinar is focused on ways to treat loss of skeletal muscle mass in the elderly with the use of a protein complementary.

The program speaker will be William J. Evans, Ph.D., FACSM, FACN Director, Nutrition, Metabolism, and Exercise Laboratory; Professor of Geriatrics, Physiology, and Nutrition; Donald Reynolds Department of Geriatric at the University of Arkansas for Medical Sciences; Geriatric Research, Education and Clinical Center (GRECC) at the Central Arkansas Veterans Healthcare System, Little Rock, Arkansas.
