Summary

This study examines the impact of daily consumption of ½ c pinto beans, compared to a control (½ c green beans), on fasting glucose, postprandial glucose and HbA1c concentrations in adults with type 2 diabetes mellitus (T2DM).

Detailed description

This study utilized a randomized, pretest-posttest, crossover (within-group) design, that includes two treatment periods \[control period (½ c. green beans each day) and pinto beans (½ c each day)\], each 12-weeks in duration with a 4- week wash-out period to determine the impact on fasting glucose, postprandial glucose and HbA1c concentrations. After a baseline wash-in period, 16 participants are randomly assigned to 2 treatment periods \[control period and pinto beans\], each 12-weeks in duration. On 28 randomized days during the wash-in period and interventions, participants keep diet records and measure a postprandial capillary glucose concentration using a glucometer 1 hour after the meal during which the pinto beans or control are consumed. Before and after each 12-week intervention, participants provide a fasted venous blood sample for glucose and HbA1c analyses.
