Wendy Dahl's current research interests focus on the relationships between fiber, diet quality, probiotics and the gut microbiome.


Wendy Dahl's extension efforts focus on increasing evidence-based knowledge of extension educators, health professionals and the general public related to wellness-promoting food and nutrition strategies, the promotion of healthful dietary behaviors and malnutrition risk reduction in older adults. Wendy's current research interests focus on the relationships between fiber, diet quality, probiotics and the gut microbiome in health and disease.

Perspective: Assessing Tolerance to Non-Digestible Carbohydrate Consumption

Advances in Nutrition

Hannah D Holscher, et. al


Human intestinal enzymes do not hydrolyze non-digestible carbohydrates (NDCs), and thus, they are not digested and absorbed in the small intestine. Instead, NDCs are partially to completely fermented by the intestinal microbiota. Select NDCs are associated with health benefits such as laxation, and blood cholesterol and glucose-lowering effects. NDCs provide functional attributes to processed foods, including sugar or fat replacers, thickening agents and bulking agents.

Higher fiber complementary food alters fecal microbiota composition and normalizes stool form in Malawian children: a randomized trial

African Journal of Food, Agriculture, Nutrition and Development

Edda Lungu, et. al


Dietary fiber favorably modulates gut microbiota and may be protective against diarrhea in sub-Saharan Africa where rates in infants and young children are high. Soybean hull is high in fiber and accessible in rural Africa; however, its use in complementary feeding has not been evaluated. The objective of this study was to determine the acceptability and feasibility of a soybean, soy hull fiber and maize (SFM) blend food; the primary outcome was compliance to the feeding protocol.

Effect of Pea Hull Fiber on Uremic Metabolites and Gut Microbiota Composition in Individuals Undergoing Hemodialysis

Current Developments in Nutrition

Asmaa Fatani, et. al


The objective was to determine the effects of pea hull fiber intake on serum uremic molecules and microbiota composition of individuals undergoing hemodialysis. A randomized, double-blind, placebo-control, crossover study was conducted with individuals undergoing hemodialysis. Following a 1-week baseline, participants consumed muffins with added pea hull fiber (15 g/d) and control muffins daily for 4 weeks in random order, separated by a 4-week washout.

Adults with Prader–Willi syndrome exhibit a unique microbiota profile

BMC Research Notes

Wendy J. Dahl, et. al


Adults with Prader–Willi syndrome (PWS) require less energy intake to maintain body weight than the general adult population. This, combined with their altered gastrointestinal transit time, may impact microbiota composition. The aim of the study was to determine if the fecal microbiota composition of adults with PWS differed from non-affected adults.
