2005 Ph.D. Nutrition, University of Saskatchewan
Dr. Dahl’s research focuses on the therapeutic effects of dietary and functional fiber, the development and sensory evaluation of foods fortified isolated fiber sources, the efficacy and effectiveness of functional fiber fortification, and prebiotic fiber and probiotic therapy in GI disease. She has provided consultation to industry and health care facilities 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. Dr. Dahl has also collaborated on a number of research projects related to malnutrition in institutionalized elderly, product development and textural standards for texture-modified foods, and the nutrition and menu standards for long term care facilities, and is currently developing an education program to improve the nutritional density and textural targets of foods intended for the frail elderly.
Current research projects include:
- Fiber intake and supplementation of chronic kidney disease patients
- Knowledge, skills, attitudes and behaviors regarding beans
- Prebiotic effects of beans, grains and isolated fiber sources
