Summary

The purpose of this research study is to determine whether a functional fiber, galactooligosaccharide, can help maintain immune strength and digestive health in free-living older adults. It is hypothesized that older adults consuming the fiber daily for 24 weeks over cold and flu season will have more healthy days due to a proliferation of beneficial bacteria within the colon which alters cytokine production and enhances natural killer cell function. Immune and gastrointestinal health will be evaluated via daily questionnaires obtained from 80 participants and from the collection of blood and fecal samples.
