Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The participants consume an infant formula and this is compared to the glucose response in the blood for 25g glucose. There are 17 infant formula's, made up from a powder mixed with water and 3 glucoses in all. 21.3g infant formula powder is added to 220ml water. Each formula is consumed once only. The participants come in on 20 seperate occassions, usually 2 to 3 times a week. The formula's are mixtures of lactose, glucose solids, dextrose, maltodextrin, galacto-oligosaccharides, fructo-oligosaccharides, oat fibre, apple fibre, docosahexanoic acid, arachidonic acid, alpha-linoleic acid and linoleic acid. Response is monitored for 120 minutes after consumption.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects respond to newspaper advertisements. They are randomised to the order in which they receive the infant formulas. Allocation is not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomization table created by computer software.
Masking / blinding
Open (masking not used)

Summary
Brief summary
The aim of this study is to evaluate to blood glucose response of a variety of infant formula products. The glycaemic index measures how blood glucose changes after a portion of food that contains 50g avaliable carbohydrate has been eaten. Teh benefit of the system is that it allows us to classify whether a food causes a large increase in blood glcuose after it is eaten, or if its response is lower and lasts for longer. Blood glucose control is especially important for people with diabetes as high levels of circulating glucose can cause cellular damage and increase their risk of coronary heart disease. Low GI foods will produce a smaller, longer lasting increase in blood glucose and hence consuming a diet high in low GI foods will improve blood glucose control in people with diabetes
