Fig. 1

After initial screening, eligible participants were randomized to a premeal almond load treatment-control sequence or to the control-treatment sequence after a run-in period of 2 weeks. Intravenous blood was withdrawn at −30, 0, 30, 60, 90, and 120 min in each period. After completion of the OGTT-based study phase, participants entered the CGMS-based study phase. The CGMS device was inserted in the subcutaneous tissue of the lateral abdominal wall for 3 days. Participants were asked to record activity, mealtime, and premeal almond load timings, which was indicated in Supplementary Fig. 1. After 3 days CGMS was removed, and participants were given a normal diet from 22 to 28 days followed by crossover and application of CGMS for another 3 days. There was no participant dropout in the study.
