Soluble Corn Fiber for Cognitive Health

Start: August 2, 2021
End: June 30, 2023
Enrollment: 40

What Is This Study About?

Studies suggest that regular consumption of dietary fiber supports physical health. This study will evaluate the effects of consuming soluble corn fiber (SCF) on cognitive function and gut health in middle-aged and older adults. Participants will be randomly assigned to consume 22 grams daily of either SCF or maltodextrin, a common food additive, for four weeks. The group assignments will then be reversed for another four weeks. All participants will complete questionnaires and provide stool specimens. Researchers will assess changes in cognitive function, including attention and memory, as well as mood. They will also evaluate any changes in the types of microbes living in the gastrointestinal system, called the gut microbiome, and the effects on digestion.
