Study type
Interventional
Description of intervention(s) / exposure
This trial aims to show that a drink containing protein and a mix of protein and soluble fibre (guar) slows starch hydrolysis and absorption of glucose.

On each of the 4 test days participants will attend the research centre at 9am having fasted overnight for 12 hours. On the first test day a continuous glucose monitor will be inserted. It will remain in place for 5 days and calibrated daily using fingerprick glucoses 4 times/day.

On each test day participants will be fed a morning meal consisting of 4 slices of white bread (50g of carbohydrate) with 5g jam on each slice. No fat topping will be provided. On two occasions the bread and jam will be preceeded by 150ml of water (control) and on the other 2 occasions preceeded by a 150ml drink containing 20g protein plus 5 g guar (treatment). The drink (control or treatment) will be taken 15 minutes before consuming the bread and jam.

The tests will be performed across four consecutive days with 12 volunteers, with the first two days randomised to treatment or control, and the second two days randomised to treatment or control.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Both the researcher who determined if the subject was eligible for inclusion in the trial, and the subject, were not aware if the subject would be allocated to the treatment or the control on a given day. Allocation was centrally performed by computer software.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by computer software (i.e. computerised sequence generation)
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?
