Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Randomized, within-subject trial comparing two breakfast-lunch combinations that only differ in calcium content of breakfast (~250mg versus 550mg). Each combination will be adminstered on one occassion only, in a random order. Volunteers will crossover to the second combination following a 2 week washout period. Breakfast will consist of rolled oats, sultanas, cream, milk and sugar while lunch will consist of a white bread sandwich of ham, tomato, butter with a serving of fruit and fruit juice.

Comparator / control treatment
The low calcium (~250mg) breakfast-standard lunch combination is the comparator treatment. Each breakfast-lunch combination will be adminstered on one occassion only, in a random order, and volunteers will crossover to the alternative combination following a 2 week washout period.

Summary
Brief summary
The primary purpose of this study is to examine whether a change in calcium intake at one meal modifies the way in which we handle the subsequent meal. We believe that increasing calcium intake at breakfast improves the body's ability to handle glucose following lunch, while promoting utilization of fat and suppressing subjective ratings of hunger.
