Noakes 1996 (2 strata) To compare the effects of a diet enriched in low or high amylose starch, or oat bran, on blood glucose, insulin, lipids and bowel function. 23 overweight hyperlipidaemic subject. 10 females (45-61y) and 13 males (44-64y). considered as 2 trials; 1 in men and 1 in women Participants consumed bread, cereal, pasta, muffins made with oat bran or high amylose starch on a low fat low fibre background diet. Females consumed 87g oat bran and males consumed 121g oat bran. 3x 4wk intervention. Compliance by daily food records. Dietary intake by 3d weighed food records during each period. Blood lipids measured enzymatically, LDL-C calculated. RMANOVA and analysis. Minimised by cross-over design. No significant change in cholesterol concentration. High amylose stratum selected as control as it provided a better of fibre intakes. The low amylose stratum was not considered further. Onning 1999 To study the properties of an oat milk deprived of insoluble fibre in men 66 men with moderate hypercholesterolaemia (mean age, 62.6y). 52 men completed the study. Participants consumed 0.75L oat milk/day with a daily -glucan intake of 3.825g. Controls drank equivalent volume rice milk. 2 x 5wk intervention with 5wk washout period. Blood lipids measured using automated analyser, LDL-C calculated. Analysed using paired t tests and Wilcoxon nonparametric tests (lipid values were not normally distributed) Minimised by cross-over design. Compliance and dietary intake information not recorded. High attrition due to unwillingness to continue. Significant decreases in total cholesterol and LDL-C. No change in HDL-C. Taste and sensation of milks were tested; participants could not tell them apart.
