A randomized crossover study design will be carried out in accordance with the guidelines of the Human Subjects Protection Committee of the University of California, Los Angeles. All subjects will give written informed consent before the study begins. There will be two groups of participants (normal and overweight/obese). Each participant will consume oatmeal prepared with 1 cup of 2% milk served with or without 6 g of ground cinnamon in random sequence. At each meal consumption blood will be collected to measure postprandial glucose and insulin at 0, 30, 60, 90, 120, 150 and 180 minutes.
The objective of the proposed study is to investigate the effect of cinnamon on the postprandial glycemic response to a high glycemic index meal in normal and overweight/obese prediabetic subjects
