Plasma metabolic excursions in MetS persons who followed a DGA-based diet containing potatoes (DGA + POTATO) or bagels (DGA + BAGEL) for 2 weeks prior to completing a glucose tolerance test. (A) Plasma glucose, (B) insulin, (C) CCK, and (D) MDA during a 2-h postprandial period following the ingestion of 75 g of glucose. Data (means ± SE, n = 27) are expressed as changes from baseline (0 min) and were analyzed by 2-way RM ANOVA with Bonferroni’s post-test to assess effects due to time, treatment, and their interaction. p < 0.05 was considered statistically significant, and data are annotated (a > b > c) to visualize post-hoc effects due to time or time x treatment as appropriate. Abbreviations: CCK, cholecystokinin; DGA, Dietary Guidelines for Americans; MDA, malondialdehyde; and MetS, metabolic syndrome.
