Study type
Description of intervention(s) / exposure
Following an overnight fast, on two separate occasions separated by a one-week washout, one of two randomised interventions will be served, comprising whole-grain wheat ready-to-eat breakfast cereal prepared by either regular or additional processing methods, with low fat milk, standardised to 50g available carbohydrate (approximately 4 biscuits and 300 ml milk).

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be enrolled by answering advertisements about the trial, considering the Information to Participants" form, followed by medical and eligibility criteria screening. Once the participant has provided informed consent, allocation concealment will be achieved using sealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s

Intervention assignment

Not Applicable
Type of endpoint(s)
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.

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.
