ObjectiveTo compare the effects of Salba and flax, two nutritionally similar, high fiber grains whose main difference is viscosity, on postprandial glycemia and appetite.MethodsUsing an acute randomized, single‐blind, crossover design, 9 healthy subjects (4M:5F; BMI 22.7±4 kg/m2) received, on 3 different occasions, a 50g glucose drink alone or with either 25g Salba or 31g flax added, which were matched for fiber. Capillary blood was taken and hunger questionnaires completed at fasting, 15, 30, 45, 60, 90 and 120 min post‐consumption. Viscosity was measured using a Brookfield Dial Viscometer.ResultsThe viscosity of Salba was approximately 3 times higher than that of flax. Salba significantly reduced the glucose iAUC compared to control (p=0.049), whereas flax did not. Salba and flax consumption increased 2hr satiety scores compared to control by 83% and 55%, respectively (NS).ConclusionsAddition of Salba, but not flax, to a glucose drink significantly lowers postprandial glycemia. Although Salba increased satiety to a greater extend than flax, this did not reach statistical significance. These preliminary data suggest that the greater effectiveness of Salba may be due to its higher viscosity level. Further research is warranted to assess the effects of Salba on postprandial glycemia and appetite control.Research support: Salba Smart Natural Products, Denver, CO, USA.
