Relationship between baseline SCFA profiles and habitual intake of food groups. A Baseline SCFA profiles and average food intakes among participants. Participants (rows) clustered based on proportional SCFA profiles. Cells values represent z-scores within each column. Loadings shown of proportional SCFA concentrations (B) and consumed food groups (C) along canonical axes one and two resulting from co-inertia analysis of SCFA and diet data (p = 0.031). Each axis is represented identically in each plot, so that eigenvectors (direction of arrows) correspond between the SCFA and food group plots and the magnitude of eigenvalues (length of arrows) is related to the strength of that component in the axis loading
