Abstract

Objective: To determine the influence of porridge made with milk, honey, and either rolled oats (R) or pinhead oats (P) on postprandial glycemia and satiety. Methods: Fifteen healthy participants were recruited, but because of noncompliance with the protocol, only 13 participants were included in the final analysis. In a randomized, crossover design, participants consumed porridge made with milk, water, honey, and either R or P. Finger-prick blood samples were taken at baseline and at 15, 30, 45, 60, 90, and 120 minutes following consumption of the porridge to determine blood glucose concentrations. Visual analog scales were used at the same time points to assess appetite sensations. Incremental area under the blood glucose concentration versus time curve (IAUC), ignoring area below the baseline, was used to assess glycemia. Results: Porridge made with P reduced the blood glucose IAUC by 19.51 mmol/L × 120 minutes (95% confidence interval: 5.18, 33.84 mmol/L × 120 minutes; p = 0.012), although no differences in peak or time to peak blood glucose concentrations were observed (p = 0.603 and 1.00, respectively). Hunger was not affected by the type of oats used (p = 0.991), yet participants felt fuller following consumption of R compared with P (p = 0.024). Conclusions: Glycemia is improved yet feelings of fullness are attenuated following consumption of porridge made with P compared with R.
