Effects of native banana starch supplementation on body weight and insulin sensitivity in obese type 2 diabetics

Int J Environ Res Public Health. 2010 May;7(5):1953-62. doi: 10.3390/ijerph7051953. Epub 2010 Apr 28.


Few fiber supplements have been studied for physiological effectiveness. The effects of native banana starch (NBS) and soy milk (control) on body weight and insulin sensitivity in obese type 2 diabetics were compared using a blind within-subject crossover design. Subjects undertook two phases of 4-week supplementation either with NBS or soy milk. Patients on NBS lost more body weight than when they were on control treatment. Plasma insulin and HOMA-I were reduced after NBS consumption, compared with baseline levels, but not significantly when compared to the control treatment. Results support the use of NBS as part of dietary fiber supplementation.
