Postprandial plasma insulin concentrations over 7 h after consuming high-fat and high-carbohydrate (HFHC) challenge test meals with and without addition herbs and spices (H/S) followed by fasting 24-h plasma insulin concentration in (A) All evaluable subjects (n = 23); (B) subjects with age <40 years (n = 15); (C) subjects with age ≥40 years (n = 8). Main effect of meal (P = 0.12), time (P <0.0001), meal by time interaction (P = 0.04), and meal by time by age interaction (P = 0.001). Data are means ± standard error of mean. Data were log-transformed prior to statistical analysis. PROC MIXED (SAS Institute, Inc., Cary, North Carolina) was used for repeated measures. *Significant meal effect at the time point, P <0.05.
