This research study will be conducted in two parts. The first part will consist of selecting appropriate screening and assessment tools for Veterans undergoing elective surgery and identifying the number of Veterans who are malnourished and at risk of malnutrition. The second portion of the study will be to determine if a protein-enhanced diet before and after surgery will improve function and postoperative outcomes and compare the results to an education control group.
