Plasma Concentrations of GLP-1 and PYY in Rats Fed Dietary Fiber Depend on the Fermentability of Dietary Fiber and Respond to an Altered Diet : Table 2

Table 2: Effect of various dietary fiber on body weight gain, intake, GLP-1, PYY and cecal.
^a,b Mean values within a column with unlike superscript letters were significantly different (P < 0·05).
Data were analyzed by one-way ANOVA, followed by the Tukey–Kramer test.
