Inulin Improves Postprandial Hypertriglyceridemia by Modulating Gene Expression in the Small Intestine

Figure 1. Body weight evolution. Inulin supplementation was introduced after 4 weeks. Data are presented as mean ± SEM and analyzed with a mixed model ANOVA followed by Tukey post hoc test. * p < 0.05 versus CT, § p < 0.05 versus CT + I.
