Study Summary

An individual's immune and metabolic status is coupled to consumed carbohydrates. Complex carbohydrates that are not digested by human enzymes may influence host biology by impacting microbiota composition and function, or act in a yet-unknown microbiota-independent manner. Prebiotics offer a promising safe route to influence host health, possibly via the microbiota. However, it remains largely unknown to what extent immune function and metabolism can be modulated by prebiotics.

Primary Outcome

Change from baseline in Cytokine Response Score (CRS) at 6 weeks. The CRS is a single composite measure of cell-type specific activation of signaling pathways from ex vivo cytokine stimulation of blood samples. This provides a measure of immune response capacity which may be an indicator of immune fitness. The CRS will be calculated as described in Shen-Orr et al, Cell Systems, 2016. The CRS is the sum of 15 age-associated normalized cytokine responses identified in Shen-Orr et. al: In CD8+ T ce
