Background Previous research has shown that whole pulses reduce glucose, hunger and appetite responses compared to other carbohydrate sources. However, it is not known if differential responses occur with consumption of blended pulses or when taking Beano ® (which reduces GI discomfort) with pulses. We therefore tested the hypotheses that blended pulses and/or consuming Beano increase postprandial glucose and appetite. Methods Participants (n=12; BMI 23±3kg/m 2 ; aged 28±10y (mean±SD)) consumed breakfast burritos containing ≥½c of whole (W), blended (B) or no lentils (C), each in combination with 3 Beano or placebo pills in a randomized, crossover, double‐blind, placebo‐controlled trial. AUCs over 3h were calculated. Results Preliminary results showed fullness (p=0.01) and hunger (p=0.04) were lower, and desire to eat (p=0.052) was higher, for Beano compared to placebo. There was a significant meal by Beano interaction effect on glucose (p=0.01), with Beano having 1.3, 1.2, 2.4% lower AUCs than placebo for W, B and C, respectively. Also, W and B lentils had 2.5 and 4.8% lower AUCs than C. Except for desire to eat, all results were in a direction where Beano gave lower values compared to placebo. Conclusion Blended and whole lentils have similar effects on lowering postprandial glucose compared to a control meal, and Beano has only small effects on postprandial glucose and appetite.
