(Lu et al. 2000) in Australia Crossover To compare the effect of meals containing AX-rich fibre on postprandial glucose and insulin responses in healthy subjects. 14 adults completed the study (5 men and 9 women) aged 32.0±6.6 years, with BMI of 22.7±4.3 kg/m2. isoenergetic breakfasts, comprising bread, margarine, and jam, and contained 0, 6, and 12 g AX-rich fibre. The meals provided 75 g available carbohydrate. Total fibre from wheat in the included strata was 6 g, containing 62.8% w/w total AX and therefore delivering 3.7 g of AX per eating occasion. Venous blood glucose was drawn before the intervention and at frequent intervals up to 120 min following the intervention. Plasma glucose was measured with an automatic analyser (Hitachi 705) and colorimetric reagents (Boehringer Mannheim). GLM was used to compare the effects of the intervention. Reduced by crossover design. Glucose: Peak postprandial glucose concentration in control meal was significantly (P < 0.001) higher than with 6 g AX-rich fibre and meals with 12 g AX-rich fibre. Mean difference between the included stratum and the control was -0.80±0.27 mmol/l. Insulin: no significant difference between the included (6 g) or the (12 g) strata and the control (0 g) at the peak. A significant (P <0.05) reduction in postprandial insulin concentration was observed Intervention delivering 6 g of AX-rich fibre has been used in the trial
