Statistical methods / analysis
Quantitative data will be entered into and analysed by statistical applications using Microsoft Exel and IBM SPSS Statistics (V.19) with the assistance of a statistician where required. Descriptive statistics will include mean, standard deviation or standard error of the mean for all anthropometric and biochemical data collected and analysed for significance using the statistical software.

Summary
Brief summary
The aim of this study is to measure the acute (2-hour) effects following consumption of wheat whole-grain foods differing in processing treatment on obesity-related measures. This study hypothesises that the grain products that have undergone selected additional processing will contain greater nutrients and bioactive compounds and have favourable outcomes on postprandial measures compared with regular whole-grain products.
