Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All participants will be randomised to eat one meal of 100gm of bread from the new wheat flour (Yammamori) . There are 3 breads, 25%, 50% and 100% Yammamori wheat. The response to a reference carbohydrate (sugar drink) is used as a standard for comparison in these tests on 3 occasions due to the variability of the glucose response.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Volunteers will be randomly allocated by computer generated sequence to study treatments. The treatments are coded alphabetically. Locked computer files indicate treatment allocation numerically and the treatment code is concealed from research staff.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Volunteers will be initially blocked matched into 4 groups based on age, body mass index and gender, glucose level prior to randomisation by computer generated sequence
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?
