Research Interests

Dr. Dahl’s current research interests focus on examining the role of fiber and prebiotics in medical nutrition therapy, specifically the role of isolated fibers on various outcomes of chronic kidney disease. She collaborates extensively on studies related to effects of fiber, prebiotics and probiotics on overall health and wellness, gastrointestinal health, immunity and their relationship to gut microbiota. Dr. Dahl is also actively involved in the scholarship of teaching and learning, exploring ways to improve the undergraduate student’s learning experiences.


Dr. Dahl’s primary extension program focusses on food and nutrition issues of the frail elderly, specifically malnutrition and dysphagia management. She has been involved in product development, sensory testing and textural standards for texture-modified foods, nutrition and menu standards for long term care facilities, and leads educational programming to improve the nutrient density, acceptability and texture of foods intended for the frail elderly. In addition, she provides consultation to industry and health care regarding food applications for functional fiber sources and currently provides outreach to industry, food retailers, health professionals and consumers in the development and adoption of wellness-promoting foods and nutrition strategies.
