Effectiveness Trial of Functional Ice Cream vs. a Traditional Oral Liquid Nutrition Supplement in Community-Dwelling Older Adult at Risk for Malnutrition: A Pilot Study

Research Objectives:
We are seeking 20 adults who have been recommended to take an Oral Liquid Nutrition Supplement (OLNS) by their healthcare provider to participate in a research study. This clinical study aims to test our research strategy for understanding tolerance (comfort) and adherence (frequency, duration of use) for a nutritional ice cream alternative!

Participation in this research will last for no more than 12 weeks, and involves consuming both our ice cream, and a traditional OLNS, which the research team will deliver to you. In addition, we will ask you questions about the product, and about your nutrition, quality of life, and demographics. You will also be asked to perform short physical assessments in the home setting.

Jonathan Deutsch, Professor, Food and Hospitality Management, Drexel University (PI)
Rose Ann DiMaria-Ghalili, Professor, Nursing, Drexel University (Co-I)
